B. refugians n. sp.
♀. Eyes bare, moderately dichoptic; front narrow and greyish-yellow, due to a dense tomentum; ocellar triangle blackish-brown; antennae situated about middle line of head, blackish-brown with a testaceous band in the middle, in length about half the width of head; 1st and 2nd joints bristly, the former slightly elongated, the latter shorter and basin-shaped; flagellum (fig. 29) pubescent, clavate, and composed of 7 segments, the first 4 testaceous and semi-diaphanous, the remainder blackish-brown; the ultimate segment terminates in distinct hairs.
Face with a silvery tomentum darker in certain lights, a few scattered yellow hairs and a dark spot beneath the antennae; there are also a few longer yellow hairs beneath the eyes; proboscis and palpi a delicate pale yellow, the former with yellow hairs; palpi not reaching in front of proboscis, 2-jointed; the 1st densely pubescent with longer yellow hairs and a slightly darker reflection, the 2nd about as long as the 1st, minutely pubescent, fusiform, and ending in a distinct blackish-brown bristle; oral margin shiny blackish-brown with an anterior tubercle. Posterior orbits pubescent, narrowed toward the vertex, and with a tuft of long hairs below; posterior orbital hairs distinct; occiput depressed at the vertex, but slightly convex below, and of a greenish-yellow colour.
Thorax comparatively small considering the abdomen, shiny and bare but for a minute and scattered tomentum on the dorsum; humeri pale green with a dark mark beneath; dorsum tawny with darker reflections, the margins of the transverse suture and the anterior margin between the

humeri blackish-brown; in certain lights may be seen 2 lighter longitudinal stripes anterior to the transverse suture, while posterior to it are 2 black stripes, the edges of the dorsum also being here margined with black; those 4 stripes posterior to the suture do not extend to the scutellar suture; pleurae pale yellowish-green with brownish markings on the pteropleurae and mesopleurae; the lower half of the pteropleurae and sternopleurae dark brown; metapleurae hairy; scutellum apple-green with a darker brownish base, the spines short and pale yellow; halteres dark tawny.
Legs tawny but paler than the coxae; tarsi fuscous from the apex of the epitarsi to the onychotarsi (inclusive); in certain lights the posterior protarsi with a darker mark at the apex, posterior tibiae with a darker tawny colour above; posterior femora slightly thickened, the protarsi of all legs a little more than half the length of the whole joint.
Wings very faintly tinted with yellow; stigma pale yellow; veins brownish-yellow; auxiliary vein not sinuated; 1st section of 2nd vein about three times the length of the anterior cross-vein and almost parallel to the costa; 1st section of 3rd vein shorter than anterior cross-vein, the 2nd section slightly sinuated to the bifurcation, the anterior branch arising at a slightly acute angle and distinctly curved forward to the costa, the posterior branch curved downward and forming an obtuse angle with the 2nd section; apex of discal cell distinctly posterior to apex of 2nd vein; anterior cross-vein anteriorly oblique, vein separating the basal cells present; both basal cells closed toward the base, the 2nd of those cells being considerably narrower than the 1st.
Abdomen covered with delicate minute and bristle-like hairs, fusiform, about twice as long as the thorax and distinctly broader, composed of 7 segments, the apex upturned and bearing the 2 styliform appendages; the whole tawny but semi-diaphanous on basal half, while at the base is a blackish spot, each segment except the 1st and 6th margined posteriorly with blackish-brown, which on the 2nd, 3rd, and 4th segments extends to and along the lateral margins in the form of a triangular spot; in the middle, at the anterior margin of the 4th segment is a circular black spot; on the 5th the black margin hardly extends to the posterior corners, on the 6th it is confined more or less to the centre of the posterior margin, while on the apical segment it forms a broader and wider marking. The 1st joint of the styliform appendages is tawny, hairy, and equal in length to the 2nd, which is elongate, fusiform, and tawny on proximal half but black distally, carrying long hairs. The apical segment of the abdomen is hairy.
