CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 499 



submarginal row of eight or nine setigerious punctures; transverse 

 impression postmedian, weakly impressed and obsolete at middle, 

 marked by medially interrupted row of numerous close-set, moderate 

 punctures; surface with numerous scattered minute punctures; 

 anterior lobe with few, obsolete, small punctures laterally; posterior 

 lobe without coarser punctures. 



Scutellum: Little longer than wide, 2.08:2.02; disc shining, with 

 very many well-separated minute punctures and numerous widely 

 separated coarser punctures becoming finer toward apex, 



Hemelytron: Clavus and corium weakly alutaceous; clavus with 

 single longitudinal row of punctures; mesocorium obsoletely punctured 

 except for one complete and the suggestion of a second row of distinct 

 punctures paralleling claval suture; exocorium with few obsolete 

 punctures scattered along full length; costa with three or four setigerous 

 punctures; membranal suture almost straight, lateral angle somewhat 

 produced; membrane little longer than basal width, slightly surpassing 

 apex of abdomen. 



Propleuron : Alutaceous, without distinct punctures except ventrally 

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



Mesopleuron: Lateral area impunctate, with few oblique rugae. 



Metapleuron: Lateral margin of evaporatorium distinctly concave; 

 lateral area alutaceous, neither rugose nor punctate. 



Sternites: Alutaceous, impunctate. 



Legs: Posterior tibia without subbasal angulation ventrally, with 

 four spines on posteroventral margin. 



Length of body: 6.24. 



Type data. — Jensen-Haarup listed type material from "Lima" 

 and "Mendoza." The "Lima" specimen (Copen) was loaned for 

 study by Dr. S. L. Tuxen. This specimen bears the label "Type., 

 Coll. J-Hrp.," and is here designated lectotype. 



Specimen studied: The female type (Copen) from Lima, Peru. 



Discussion. — The median, interocular fovea around which the 

 proximal ends of the clypeal sutures diverge appears to be unique 

 not only within this genus but also within all other genera in the 

 Western Hemisphere.

Diagnosis. — The presence of four setigerous punctures on the sub- 

 margin of the head coupled with the very few scattered punctures 

 laterally on the anterior lobe of the pronotum and the single setigerous
