CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 577 



Length of body: 9.40(8.78-10.21). 



Type data. — The type female, now in the W. S. Blatchley collection 

 (Ind), was listed as coming from "near Sunland, Los Angeles County, 

 California."

Discussion. — In describing this species as new, Blatchley pointed 

 out its nearness to Uhler's "Pangaeus discrepans" and suggested that 

 these two forms differed from other true Pangaeus in lacking the 

 subapical impressed line on the pronotum. 



Ecological data consisted of the lone collection note given with the 

 original description, "from beneath a stone in a small semi-desert 

 area."

Diagnosis. — This species may be separated from its related species 

 by the elongate scutellum and the polished mesocorium, which is vir- 

 tually impunctate on the apical half or more, coupled with the smaller 

 size, 6.8-8.2. 



Description.— Male: Oval, widest behind the middle. 



Head: Length about two-thirds width, 1.23(1.24-1.26) :1.83(1.71- 

 1.91); interocular width, 1.22(1.16-1.26); anterior margin a broad 

 semicircle, sometimes slightly truncated apically; juga as long as 

 clypeus or slightly longer and nearly or quite meeting anterior to it; 

 surface with several radiating, moderate rugae and numerous minute 

 punctures; ocelli very small, separated from eye by a space equalling 

 about four times transverse ocellar diameter; jugum ventrally polished, 

 unpunctate; maxillary plate faintly alutaceous, with few or no punc- 

 tures. Antennal segments: I, 0.41(0.40-0.43); II, 0.49(0.46-0.53); 

 III, 0.47(0.43-0.50); IV, 0.64(0.60-0.70); V, 0.65 (0.60-0.70). Buc- 

 culae about as high as labial II. Labial segments: I, 0.64(0.60- 

 0.70); II, 1.00(0.96-1.06); III, 0.84(0.76-0.90); IV, 0.51(0.57-0.54).
