CYDNIDAE OF THE WESTERN HEMISPHERE FROESCHNER 505 



that the large ocelh, which are separated from an eye by less than the 

 transverse diameter of an ocellus (fig. 46), appear to be serviceable 

 for that purpose within the subgenus. 



Description. — Male: Oval, widest near midlength. 



Head: Length about two-thirds width, 1.39(1.15-1.56) :2. 14(1. 84- 

 2.36); interocular width, 1.15(0.98-1.30); anterior outline a slightly 

 elongate semicircle, juga as long as or longer than clypeus and nearly 

 or quite contiguous beyond its apex; surface pohshed, with few scat- 

 tered minute punctures, apex distinctly recurved; juga longitudinally 

 impressed medially, with one submarginal setigerous puncture im- 

 mediately anterior to eye; ocelli large, separated from eye by space 

 less than transverse ocellar width (fig. 46) ; jugum ventrally and maxil- 

 lary plate, except posterior fourth, polished, impunctate. Antennal 

 segments: I, 0.39(0.33-0.43); II, 0.41(0.33-0.46); III, 0.57(0.47-0.63); 

 IV, 0.69(0.56-0.76); V, 0.78(0.66-0.83). Bucculae (fig. 24) almost as 

 high as labial II; labium reaching between or slightly beyond middle 

 coxae. Labial segments: I, 0.70(0.58-0.83); II, 1.19(0.93-1.30); III, 

 0.97(0.80-1.06); IV, 0.56(0.50-0.62). 



Pronotum: Length more than half width, 2.47(2.15-2.86) :4. 55(3. 84- 

 5.04); anterior margin shallowly, doubly emarginate; lateral margin 

 nearly straight on basal two-thirds, with four or five setigerous punc- 

 tures submarginally; transverse impression weak but evident, marked 

 by medially interrupted row of punctures; anterior lobe with median 

 line finely impressed on apical half, impunctate except for variable 

 lateral patch; posterior lobe with several to many punctures scattered 

 across full width, most abundant medially. 



Scutelhim: Length equal to or slightly longer than width, 2.97(2.34- 

 3.16) :2. 79(2. 34-3. 16); disc polished, with numerous punctures scat- 

 tered nearly to apex. 



Hemelytron: Clavus and corium alutaceous; clavus with one com- 

 plete and sometimes a second incomplete row of punctures; meso- 

 corium with one complete and sometimes another incomplete or com- 

 plete row of punctures, elsewhere impunctate or with obsolete to dis- 

 tinct punctures, especially basally and at outer apical angle; exocorial 

 punctures likewise varying from absent to distinct; costa with two 

 setigerous punctures; membranal suture straight, lateral angle feebly 

 or not produced; membrane longer than basal width, surpassing apex 

 of abdomen. 



Propleuron: Weakly alutaceous, punctured in depression and some- 

 times anterior to acetabulum; prosternal carinae less than half as 

 high as labial II. 



Mesopleuron: Lateral area with few or no punctures. 



Metapleuron: Lateral margin of evaporatorium weakly or not con- 

 cave; lateral area impunctate.
