CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 555 



Description. — Male: Oval. 



Head: Wider than long, 1.47(1.36-1.56): 1.02(0.93-1.10); inter- 

 ocular width, 0.97(0.90-1.04); juga semicircular, slightly but dis- 

 tinctly surpassing clypeus, not or only slightly converging in front of 

 latter and leaving a rectangular emargination at apex of head; eyes 

 projecting by more than half their width; clypeus with a few coarse, 

 transverse rugae and two subapical setigerous punctures; jugum with 

 a submarginal row of coarse, close-set punctures giving rise to long 

 cilia and stout pegs, surface with numerous coarse punctures, some of 

 them contiguous in radiating rugae; vertex polished, a few coarse 

 punctures medially; ocelli present, separated from eye by more than 

 ocellar width; jugum ventrally polished, impunctate; maxillary plate 

 with few coarse punctures, especially posteriorly. Antennal seg- 

 ments: I, 0.36(0.31-0.40); II, 0.28(0.25-0.33); III, 0.34(0.31-0.38); 

 IV, 0.43(0.40-0.48); V, 0.41(0.38-0.46). Bucculae lower than labial 

 II; labium reaching between middle coxae. Labial segments: I, 0.60 

 (0.56-0.63); II, 0.86(0.81-0.90); III, 0.63(0.60-0.66); IV, 0.48(0.46- 

 0.51). 



Pronotum: Width almost twice length, 3.15(2.90-3.41): 1.67(1.47- 

 1.82); anterior margin moderately biemarginate; lateral margins 

 entire, not emarginate opposite ends of transverse impression; latter 

 postmedian, weakly indicated and usually obsolete medially; anterior 

 lobe impunctate except for broad lateral baud of coarse, setigerous 

 punctures; posterior lobe with numerous similar setigerous punctures 

 scattered over surface, those along transverse impression coarser, 

 elongate. 



Scutellum: As long as or slightly longer than width, 2.07(1.82-2.28) : 

 2.05(1.82-2.25); surface polished, with coarse, sunken punctures scat- 

 tered over disc, basal angles impunctate. 



Hemelytron: Corial areas well defined, disc with scattered moderate 

 punctures intermixed with finer ones; coarse ones along claval suture 

 forming two rows; exocorium more closely and coarsely punctured; 

 costa with many close-set, irregularly arranged setigerous punctures; 

 clavus with two irregular rows of coarser punctures; membranal 

 suture straight, lateral angle rounded; membrane reaching apex of 

 abdomen, basal width slightly more than half of length. 



Propleuron: Smooth, with a few coarse punctures at anteroventral 

 angle, in depression and near posterolateral angle; prosternal carinae 

 ventrally abruptly terminated at almost a right angle, with a broad, 

 deep trough between them. 



Mesopleuron: Evaporatorium restricted, interrupted on outer half 

 along posterior margin; lateral area in part rugose, with few coarse 

 punctures.
