CYDNIDAE OF THE WESTERN HEMISPHERE FROESCHNER 427 



Pronotum: Length half of width, 1.04:2.08; anterior margin deeply, 

 almost quadrately emarginate; lateral margin subparallel on basal 

 third, with one submarginal setigerous puncture at apical angle; trans- 

 verse impression postmedian, moderately impressed across full length, 

 medially extended anteriorly as distinct impression between convex 

 calli; anterior lobe with dense, moderate punctures laterally, anteriorly 

 and medially, calh polished, with minute punctures centrally; posterior 

 lobe densely punctate almost to hind margin. 



Scutellum: Length greater than width, L57:L30; surface shining, 

 all except basal angles with crowded, small to moderate punctures, 

 apical half with faint suggestion of median carina. 



Hemelytron: Clavus and corium polished; clavus v/ith two rows of 

 punctures; mesocorium with two complete rows of punctures parallel- 

 ing claval suture, elsewhere with abundant, distinct punctures; 

 exocorium with more abundant punctation; costa very narrowly 

 convex dorsally, without setigerous punctures; membranal suture 

 almost straight, lateral angle not prolonged; membrane slightly 

 longer than basal width, just surpassing apex of abdomen. 



Propleuron: Alutaceous, strongly punctate in depression and 

 anteriorly to acetabulum, with few fine punctures on anterior 

 convexity. 



Mesopleuron: Evaporatorium extended into posterolateral angle, 

 not reaching lateral margin of sclerite; lateral area in part rugo- 

 punctate. 



Metapleuron : Peritreme reaching almost to straight lateral margin 

 of pronotum, terminal modification large, semicircular, distinctly 

 alutaceous, more shining than evaporatorium; lateral area shining, 

 with few striae. Legs: Anterior tibia with five stout spines dorsally. 



Sternites: Polished, finely punctate medially, very coarsely so 

 laterally. 



Terminalia: Genital capsule punctate, more densely so laterally, 

 apical margin virtually straight; gonostylus as illustrated (fig. 207). 



Length of body: 4.50.

 Antennal segments: I, 0.23; II, 0.33; III, 0.34; IV, 0.48; V, 0.36. 

 Labial segments: I, 0.46; II, L06; III and IV missing. 



Pronotum: Length-width ratio, L10:2.28. 



Scutellum: Length-width ratio, L76:1.34. 



Length of body: 4.97. 



Type data. — The two females in the Uhler collection (USNM) 

 from which this species was originally described were collected in 

 McLennan Co., Tex.
