CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 487 



row of punctures paralleling claval suture, elsewhere impunctate or 

 obsoletely punctate; exocorium without distinct punctures; costa with 

 one setigerous puncture; membranal suture virtually straight; mem- 

 brane longer than basal width, surpassing apex of abdomen. 



Propleuron: Faintly alutaceous, with distinct punctures only in 

 depression; prosternal carinae less than half as high as labial II. 



Mesopleuron : Lateral area impunctate. 



Metapleuron: Lateral margin of evaporatorium straight; lateral 

 area impunctate. 



Legs: Posterior tibia with distinct, subbasal angulation on postero- 

 ventral margin which also bears only two subapical spines. 



Sternites: Finely alutaceous, impunctate. 



Terminalia: Genital capsule finely alutaceous, punctate laterally; 

 apical margin slightly convex at middle, gonostylus as illustrated (fig. 

 227). 



Length of body: 6.22(5.84-6.60). 



Type data. — Holotype male (USNM 64421), from "Above Tepic, 

 Mexico, Mar. 23, W. M. Mann collector." Paratype, 1 male (RLU) 

 from Tejupilco, Mexico, June 18, 1933, H. E. Hinton and R. L. 

 Usinger. 



Discussion.— The presence of a deep transverse impression on the 

 pronotum is reflected in the name impressus.

Diagnosis. — As here determined, laevigatus may be recognized in 

 the subgenus by its large size, single setigerous puncture on submargin 

 of head and one on costa and lack of a ventral, subbasal angulation on 

 the posterior tibia. 



Description.— Based on one male specimen, the type. Male: 

 Oval, widest behind midlength. 



Head: Length about two-thirds width, 1.13 : 1.68; interocular width, 

 1.06; anterior outline semicircular, juga slightly longer than clypeus, 

 narrowly contiguous above its apex; surface shining, with few moder- 

 ate, radiating rugae and scattered minute punctures; jugum longi- 

 tudinally impressed medially, with one submarginal setigerous punc- 

 ture; ocelli small, separated from eye by space distinctly more than 

 transverse ocellar width; jugum ventrally and maxillary plate (except
