damage?) and all tarsi, and the pronotum is fractured. In the original 

 description the equality of antennals II and III was noted. This is an 

 unusual feature within the genus and would suggest that the species 

 had not been properly placed. However, the type not only shows the 

 antennal condition as described by Signoret, but also has the general 

 shape and osteolar and leg modifications of Cyrtomenus, thereby con- 

 firming the generic assignment.

Diagnosis. — This species may be recognized by a combination of 

 three features: regularly rounded outline of head, less than 10 setiger- 

 ous punctures on costa, and the short labium which does not surpass 

 or only very slightly surpasses the posterior coxae. 



Description. — Male : 



Head: Length more than half width, 1.79(1.69-1.91) :2.63(2.60- 

 2.70); interocular width, 1.68(1.56-1.75); anterior outline a flattened 

 semicircle, clypeus nearly or quite as long as juga, moderately to 

 strongly narrowed apically; surface shining, with faint to moderate, 

 radiating rugae, punctation fine or absent; ocelli large, separated from 

 eye by space slightly greater than transverse ocellar width; jugum 

 ventrally and maxillary plate shining, impunctate. Antennal seg- 

 ments: I, 0.56(0.51-0.60); II, 0.41(0.36-0.45); III, 0.67(0.66-0.70); 

 IV, 0.72(0.70-0.73); V, 0.71(0.70-0.73). Bucculae low, about half as 

 high as labial II; labium reaching between or slightly beyond pos- 

 terior coxae. Labial segments: I, 1.10(1.01-1.16); II, 1.59(1.50-1.66); 

 III, 1.66(1.60-1.69); IV, 1.34(1.23-1.40). 



Pronotum: Length more than half width, 3.66(3.31-3.83) : 6. 15(5.70- 

 6.27); lateral margin with 16 to 18 setigerous punctures submargin- 

 ally; transverse impression more strongly impressed laterally than 

 medially, marked with irregular, medially interrupted row of coarse 

 punctures; anterior lobe impunctate except for few punctures laterally 

 and irregular, transverse row of coarse punctures subapically; pos- 

 terior lol)e polished, with few widely scattered punctures. 



Scutellum: Length subequal to width, 4.13(4.05-4.20) :4. 12(4.05- 

 4.19); disc impunctate or with few widely scattered punctures. 



Hemelytron: Clavus and corium pohshed; clavus with one complete 

 row of punctures, sometimes also with several scattered punctures; 

 mesocorium with two rows of punctures paralleling claval suture,
