Pentatominae

1. Juga (lateral lobes of face) considerably longer than tylus (median lobe) and wholly or largely enclosing it in front 2
Juga about as long as tylus and not enclosing it in front 3
2. Body and legs black, body with margins narrowly tawny, widest above on abdomen second and third antennal segments subequal in length; anterior angles of pronotum widely raised and alate: known only as a brachypterous alpine form, without ocelli; length about 9 mm. Hypsithocus hudsonae Bergroth (Figs. 16, 37, 49)
Brown, connexivum with transverse black bar at anterior and posterior margin of each segment; second antennal segment much longer than third, anterior angles of pronotum not widely raised and alate, fully winged, membrane of hemelytra reticulately veined; with ocelli; common and generally distributed, length, 8–10 mm. Dictyotus caenosus (Westwood) (Figs 12, 22, 39, 50, 57)
3. Green (one uncommon colour form of Nezara viridula is orange, overwintering forms more or less brown); connexivum without large black markings, at most with a small black spot at posterior angle in each segment, rostrum not or scarcely extending on to abdomen, abdominal sterna without large black punctures; metathoracic evaporating areas only weakly rugulose, of uniform colour, normally yellowish-green; posterior margin of spout of metathoracic scent-gland orifice gradually curved or nearly straight 4
Brown, with a conspicuous pale band along each side of pronotum; connexivum with large, irregular, dark patches

rostrum very long, extending well back on to abdomen; in addition to ordinary punctation, a series of very large black punctures near posterior margins of 2nd to 6th abdominal sterna; meso- and metathoracic evaporating areas strongly rugose, reddish-brown mottled with black; spout of metathoracic scent-gland orifice with posterior margin strongly incurved about halfway from base, apical half much narrowed; length about 9 mm Antestia orbona Kirkaldy* (Figs. 14, 23, 38, 45)
4. Large (length 14–16 mm); posterior angles of pronotum rounded and not produced; ventral thoracic keel very low, ridge-like, only slightly notched behind; abdominal spine convex on ventral surface; posterior margin of 7th abdominal sternum in ♀ roundly, and rather shallowly excavated; posterior margin of 9th abdominal sternum in ♂ deeply excavated between the lateral lobes 5
Smaller (length 9–11 mm.); posterior angles of pronotum acute and produced; ventral thoracic keel large, high, platelike, deeply cleft behind to receive anterior abdominal spine, which is flattened on ventral surface; posterior margin of 7th abdominal sternum in ♀ very deeply and almost squarely excavated; posterior margin of 9th abdominal sternum in ♂ not deeply excavated, with a median lobe extending further back than lateral lobes Cuspicona simplex Walker* (Figs. 13, 36, 48, 56)
5. Dorsal surface shining, punctures remote, those of pronotum shallow, irregular, and confused with rugulae; head impunctate but transversely rugose; scutellum with apex broadly rounded and without any pale or black spots on anterior margin; spout of metathoracic scent-gland orifice produced as a long ridge ending near antero-lateral angle of segment; posterior margin of 9th abdominal sternum in ♂ concave between lateral lobes, which are strongly sinuate behind and bilobed; posterior margin of each anterior genital valve in ♀ strongly convex Glaucias amyoti (A. White) (Figs. 11, 21, 35, 46, 54)
Dorsal surface dull, closely punctate, especially on pronotum and scutellum; head closely punctate, not distinctly transversely rugose; scutellum with apex more narrowly rounded and with three small yellowish spots on anterior margin and a small black spot on each anterior angle; spout of metathoracic scent-gland orifice ear-shaped, short, apex distant from lateral margin of segment; posterior margin of 9th abdominal sternum in ♂ convex between lateral lobes, which are not sinuate behind and are subtriangular; posterior margin of each anterior genital valve in ♀ nearly straight or slightly concave Nezara viridula (Linn.)* (Figs 10, 40, 47, 55)
