CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 473 



to a specimen from "Mexique." Horv^th (1919, p. 236) called atten- 

 tion to this error and proposed the new name Pangaeus rugiceps for 

 this Mexican specimen, which thus becomes the type of rugiceps. 

 The vspecimen was originally in Signoret's own collection.

Discussion. — Signoret's erroneous application of Herrick-Schaef- 

 fer's name is quite understandable, especially if he had only very 

 hmited material of hilineatus and thus was not aware that individuals 

 of hilineatus did show rugae on the head. The figure of rugifrons, 

 especially in rugae and outline of the head, is very suggestive of the 

 present species. The type locality, however, precludes the employ- 

 ment of that name for this species. 



Pangaeus (Homaloporus) setosus, new species 



Plate figures 49, 222 



Diagnosis. — This species may be recognized within the subgenus 

 by the presence of numerous tubercles on the ventral surface of the 

 posterior femur (as in fig. 154) in combination with a partial, sub- 

 marginal row of setigerous punctures on the anterior half or more of 

 the head (fig. 49). 



Description. — Male: Oval, somewhat parallel- sided. 



Head: Length almost two-thirds width, 1.18(1.00-1.26):!. 84(1.71- 

 1.95); interocular width, 1.17(1.06-1.26); anterior outline elongate, 

 wealdy truncate semicircle, juga longer than and nearly or quite 

 contiguous beyond apex of clypeus; surface shining, with numerous 

 minute punctures and partial, radiating rugae; jugum depressed dis- 

 cally, with four or five setigerous punctures submarginally in front 

 of eye and on apical half a partial row of close-set setigerous punctures 

 giving rise to a row of short, stout pegs (fig. 49) ; ocelli small, situated 

 behind line connecting hind margins of eyes, removed from eye by 

 more than two times a transverse ocellar width; jugum ventrally and 

 maxillary plate shining, impunctate. Antennal segments: I, 0.40 

 (0.38-0.46); II, 0.52(0.50-0.60); III, 0.55(0.46-0.66); IV, 0.69(0.60- 

 0.76); V, 0.75(0.70-0.83). Bucculae about as high as labial II, 

 obliquely terminated posteriorly; labium reaching between middle
