CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 435 



Pronotum: Length slightly more than half of width, 0.87(0.84- 

 0.90) : 1.60(1.56-164) ; anterior margin moderately, simply emarginate; 

 lateral margin straight on basal half, without submarginal row of 

 setigerous punctures; transverse impression obsolete, postmedian, 

 without defining row of special punctures; anterior lobe with numer- 

 ous crowded punctures laterally, subapically and between calli, latter 

 with minute punctures discally; posterior lobe with fine punctures 

 over entire width, these mLxed with coarser ones anteriorly. 



Scutellum: Longer than wide, 1.16(1.15-1.17) : 0.94(0.93-0.95); shin- 

 ing; surface, except basal angles, with scattered fine and coarse 

 punctures. 



Hemelytron: Clavus and corium polished or weakly alutaceous; 

 clavus with 1]^ rows of punctures; mesocorium with two rows of punc- 

 tures paralleling claval suture, elsewhere punctures becoming much 

 finer and more v/idely scattered towards apex; exocorium punctate 

 similar to mesocorium; costa flattened, slightly rcflexed, without 

 setigerous punctures; membranal suture straight, lateral angle not 

 prolonged; membrane longer than basal width, reaching apex of 

 abdomen. 



Propleuron: Anterior convexity with numerous crowded, longitu- 

 dinal rugulae, depression with coarser punctures; prosternal carinae 

 less than half as high as labial II, abruptly terminated posteriorly. 



Mesopleuron: Evaporatorium reaching into posterolateral angle 

 but not to side of margin of segment; lateral area in part coarsely 

 rugopunctate. 



Metapleuron: Peritreme terminated by large, semicircular lobe 

 reaching almost to lateral margin of evaporatorium; lateral area with 

 few distinct striae. 



Legs : Anterior tibia with five stout spines dorsally. 



Sternites: Weakly alutaceous and minutely punctate, with few 

 distinct punctures and weak rugae laterally near spiracular area. 



Terminalia: Genital capsule with few more punctures laterally, 

 apical margin entire, wealdy convex; gonostylus as illustrated 

 (fig. 211). 



Length of body: 3.17(3.09-3.29). 



Female: Similar to male. 



Head: Length-width ratio, 0.52(0.50-0.56) :0.79(0.78-0.83); inter- 

 ocular width, 0.54(0.53-0.56). Antennal segments: I, 0.16(0.16-0.19) ; 



II, 0.17(0.16-0.20); III, 0.18(0.16-0.23); IV, 0.24(0.21-0.27); V, 0.30 

 (0.27-0.33). Labial segments: I, 0.20(0.20-0.22); II, 0.38(0.33-0.41); 



III, 0.31(0.30-0.33); IV, 0.24(0.22-0.30). 



Pronotum: Length-width ratio, 0.92(0.88-0.95) : 1.67(1.58-1.76). 

 Scutellum: Length-width ratio, 1.23(1.17-1.31) :0.98(0.93-1.06). 

 Length of body: 3.17(3.09-3.29).
