Description. — Male: Oval. 



Head: Length about two-thirds width, 1.29(1.24-1.36): 1.92(1.89- 

 2.01); interocular width, 1.41(1.36-1.43); anterior outhne a slightly 

 truncated semicircle, clypeus almost as long as juga, narrowed apically, 

 with two subapical setigerous punctures; submarginal setigerous punc- 

 tures bearing full row of stout pegs and few long hairs; surface flat- 

 tened, obsoletely punctate, moderate rugae radiating from eyes by 

 space greater than tln-ee times transverse ocellar width; jugum ven- 

 trally and maxillary plate impunctate. Antennal segments: I, 

 0.44(0.41-0.50); II, 0.39(0.36-0.41); III, 0.48(0.45-0.50); IV, 

 0.57(0.55-0.60); V, 0.62(0.61-0.64). Bucculae higher than labial II, 

 almost semicircular; labium reacliing between middle coxae. Labial 

 segments: I, 0.67(0.63-0.83); II, 0.98(0.96-1.00); III, 0.84(0.80-0.96); 

 IV, 0.65(0.63-0.66). 



Pronotum : Length more than half width, 2.56(2.50-2.70) :4. 67 (4.56- 

 4.76); anterior margin deeply, roundly emarginate; lateral margin 

 entire, not emarginate, with submarginal row of 20 to 23 setigerous 

 punctures; transverse impression absent or weakly indicated laterally; 

 disc with few widely scattered, very fine punctures. 



Scutellum.: Length usually slightly greater than width, 3.07(3.00- 

 3.15) :2. 96(2. 85-3. 01); discally with few scattered, moderate punc- 

 tures. 



Hemelytron: Clavus and corium polished; clavus with UTegular row 

 of punctures; mesocorium with obsolete, fine punctures becoming 

 slightly more distinct basally, row paralleling claval suture represented 

 by few, usually separated punctures; exocorial punctation stronger, 

 more abundant than that on mesocorium; costa with four setigerous 

 punctures; membranal suture nearly straight (fig. 82); membrane 

 reaching base of abdomen. 



Propleuron: Shining, with distinct punctures in depression and 

 above acetabulum; prosternal carinae less than half as high as labial 

 II, truncated posteriorly. 



Mesopleuron: Evaporatorium interrupted posteriorly by polished 

 band; lateral area roughly rugopunctate. 



Metaplem'on: Lateral margin evaporatorium concave; lateral area 

 coarsely punctate near evaporatorium. 



Legs : Not unusually modified. 



Sternites: Smooth, punctate only laterally. 



Terminalia: Genital capsule shining, with few scattered, distinct 

 punctures, apical margin almost straight; gonostylus as illustrated 

 (fig. 254). 



Length of body: 8.55(8.40-8.70). 



Type data. — Distant's (1880) types (BrM) are from "Mexico; 

 Panama."
