CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 603 



Description. — Based on a single male. Oval, widest near midlength. 



Head: Length more than half width, 1.90:2.77; interocular width, 

 1.67; anterior outline semicircular, clypeus as long as juga and only 

 slightly narrowed apically; surface convex with scattered minute 

 punctures and weak, incomplete radiating rugae; jugum submarginally 

 with three widely separated setigerous punctures; ocelli large, separated 

 from eye by a space subequal to transverse ocellar width; juga 

 ventrally polished, impunctate; maxillary plate on apical half polished 

 with a few scattered punctures; posterior half alutaceous and punctate. 

 Antennal segments: I, 0.66; II, 0.70; III, 0.70; IV, 1.00; V, 1.00. 

 Bucculae higher than labial II; labium reaching between posterior 

 coxae. Labial segments: I, 1.30; II, 1.99; III, 1.82; IV, 1.31. 



Pronotum: Length more than half width, 3.31 :6. 30; anterior margin 

 shallowly, doubly emarginate; side margins entire, very weakly 

 sinuate at midlength, with six or seven submarginal setigerous 

 punctures; transverse impression obsolete, absent medially, marked 

 by medially interrupted row of very close-set punctures; anterior 

 lobe with curved, subapical band of intermixed minute and close-set 

 coarse punctures; laterally similarly but with mixed sparser punctures; 

 posterior lobe with scattered moderate and more numerous minute 

 punctures. 



Scutellum: Longer than broad, 1.79:1.67; polished, with numerous 

 minute punctures and scattered coarser punctures discally becoming 

 finer toward apex, 



Hemelytron: Corium and clavus polished; clavus with two lateral 

 exterior rows and one mesal row of punctures; mesocorium with two 

 complete rows of punctures paralleling claval suture, discally with 

 scattered fine punctures becoming crowded toward apex; exocorium 

 for full length with numerous crowded punctures over most of surface ; 

 costa depressed, flattened, with two setigerous punctures on basal 

 half; membranal suture nearly straight, lateral angle little produced; 

 membrane surpassing apex of abdomen, longer than basal width. 



Propleuion: Weakly punctate, rugose on anterior convexity, 

 distinctly punctate in depression and laterally on posterior convexity, 

 prosternal carinae very low, less than half as high as labial II. 



Mesopleuron: Evaporatorium interrupted near posterior margin by 

 polished band (as in fig. 108); lateral area roughened. 



Metapleuron: Evaporatorium occupying more than three-fourths 

 of segment, side margin straight; lateral area impunctate. 



Sternites: Polished, with weak to obsolete minute punctures over 

 most of surface and longitudinal rugae laterally. 



Legs: Anterior tibia with subquadrate lobe at apex of lower margin 

 (fig. 128); posterior leg (fig. 149) with a prominent knob near middle
