Text-Figure 23.—Hyperechia consimilis Wood. the dorsal and posterior mesopleuron, the pteropleuron, the posterior hypopleuron and a wide band on the meta- pleuron with dense, long pile. Mesopleuron without bristles; metanotal slopes micropubescent only; tegula is pubescent only or may have some short, stiff setae; lateral metasternum with only short, scanty pile; ven- tral metasternum with abundant long pile; postmeta- coxal areas membranous. Legs: All the femora and tibiae are especially stout; the hind femur is only moderately swollen and is plane ventrally; the hind tibia is proportionately rather more swollen and more or less arcuate, with concave ventral surface and strongly arched dorsal surface. All the femora and tibiae have a dense brush of long, stiff hairs on all surfaces but it is much longer on the dorsal and ventral surfaces; the dorsal surfaces of the first 2 or 3 basitarsal segments have a long, similar brush of pile in decreasing length. Bristles are virtually absent; all tarsi end in slender, sharp claws, chiefly bent at the apex, long, well developed pulvilli and slender em- podium, bladelike but swollen at the base. Wings: The wings are characterized by their basal breadth and apical pointed form; the marginal cell is closed, the anterior branch of the third vein is sigmoid, bent backward, ending a short distance before the wing apex; the posterior branch ends far to the rear. First posterior cell narrowed throughout its length, closed with a short or long stalk in 11 species before me. Fourth posterior and anal cells closed with a long stalk; alula quite large, extremely long but short at the base; ambient vein complete. Abdomen: The abdomen is very broad and robust and only gently convex; it is shining, with extremely short, scanty, fine, setate pile; in some species the pile is almost absent on the last four tergites. In one group of species the fi
