Thorax.
Sterno-pleural bristles strong, 3 in number, a pair being approximated a little anterior to the line of meso-pleural suture (fig. 3, a), and a single larger and longer bristle posterior to the line of this suture (a′); surface of sterno-pleurae with scattered bristles.
Ptero-pleural bristles long, 4 in number, a pair of strong (c, c′) and a pair of weak bristles (d) being arranged alternately near wing-articulation (e); around the insertion of these bristles are scattered black hairs, otherwise this segment is bare.
Meso-pleural bristles long, strong, 7 in number, 6 placed along mesopleural suture (g), the 7th, which is shorter, inserted in the vicinity of the upper anterior angle of pleura (g′).
Pro-pleural bristles strong, 3 in number (k).
Noto-pleural bristles strong, reclinate, 2 in number (fig. 4, a).

Post-sutural long, 8 in number, 4 in each row (b); the posterior ones very long, extending beyond the scutellum, not exactly in line with the others, but inserted slightly towards the post-alars.
Dorso-central bristles long, 6 in number, 3 in each row (c).
Acrostichals (d) strong, 8 in number, 4 in each row, shorter than the post-suturals; the posterior pairs are nearer to the scutellar than to the dorsal suture, the posterior ones being more erect.
Humeral bristles strong, reclinate, 5 in number, the most anterior more erect than the others; a pair upon lateral margin, one upon anterior margin, another in the centre of the humerus, and a delicate one between but in from the anterior and central chaetae (e).
Post-humeral bristles 3 in number, the anterior and posterior ones weak, not being in line with the strong intermediate bristle (f).
Pre-sutural bristles 2 in number, the one nearer to the dorsal suture weak (p).

Intra-alar bristles long, 3 in number (g).
Supra-alars (h) consisting of 3 long reclinate bristles and a weak shorter spine between the two anterior chaetae and slightly toward the intra-alar system.
Post-alar bristles long, 2 in number (l).
Scutellar bristles long; two pairs of lateral (am and pm), one pair of apical (n), and one pair of short discal bristles (o); the anterior lateral (am) and apical chaetae are of equal length; the posterior laterals (pm), being the longest of this system, extend to the posterior margin of the 2nd abdominal segment.
Thorax tawny, with fuscous reflections, which are darker posterior to the transverse suture; 4 dark-brown longitudinal stripes upon the dorsum. As the thorax is covered with short bristles, and those of the dorsum have a dark spot at the insertion, this portion is rendered darker in certain lights.
Scutellum ochreous-yellow, with cinereous reflections.
