Hemelytron: Claviis and corium shining; clavus with several 

 punctures in one longitudinal row; mesocorium finely or obsoletely 

 punctate except for one complete and basal third of second row 

 paralleling claval suture; exocorium obsoletely punctured; costa with 

 two setigerous punctures; membranal suture straight, lateral angle 

 not produced; membrane longer than basal width, surpassing apex 

 of abdomen. 



Propleuron: Faintly alutaceous, punctate only in depression; pro- 

 sternal carinae less than half as high as labial II. 



Mesopleuron: Lateral area impunctate. 



Metapleuron: Lateral margin of evaporatorium straight; lateral 

 area impunctate. 



Legs: Not specially modified, hind tibia with four spines on postero- 

 ventral margin. 



Sternites: Polished, impunctate. 



Terminalia: Genital capsule with few scattered, fine punctures; 

 apical margin very broadly and very shallowly U-shaped; gonostylus 

 as illustrated (fig. 225). 



Length of body: 5.00. 



Type data. — Holotype male (Cap), "Venezuela Exp., Culebra N. 

 Duida Terr., Amazonas, April 7-16, J. Maldonado Capriles Coll." 



Discussion.- — The name bisetosus is given in obvious reference to 

 the two setigerous punctures on each jugum. 



Pangaeus (JPangaeus) docilis (Walker) 



Plate figures 156, 226 



Aethus docilis Walker, 1867, p. 154. 

 Pangoeus [I] dallasi Signoret, 1882, p. 263, pi. 9, fig. 121, 

 Pangaeus dallasi Lethlerry and Severin, 1893, p. 69. 

 Pangaeus docilis Distant, 1899, p. 221. 



Diagnosis. — The male of docilis may be separated from all other 

 species in the genus by the subbasal angulation on the posteroventral 

 margin of the hind tibia and the single setigerous puncture on the costa. 



Description. — Male: Oval, widest near midlength. 



Head: Length two-thirds width, 0.86(0.81-0.90): 1.28(1.13-1.36); 

 interocular width, 0.78(0.72-0.83); anterior outline semicircular, 

 clypeus as long as juga and strongly narrowed apically ; surface shining, 

 impunctate, with weak rugae; jugum with one submarginal setigerous 

 puncture anterior to eye; ocelli moderate, separated from eye by space 

 more than twice transverse ocellar width; jugum ventrally and 

 maxillary plate, except basal margin, polished, impunctate. Antennal 

 segments: I, 0.24(0.21-0.26); II, 0.24(0.20-0.26); III, 0.36(0.30-0.43); 

 IV, 0.46(0.37-0.53); V, 0.55(0.48-0.60). Bucculae nearly as high as 

 labial II; labium reaching between middle coxae. Labial segments:
