BEETLES OF THE GENUS RENOCIS — BLACKMAN 385 



sulcus to appear deeper than it actually is. Ventral surface reddish 

 brown, shining, rather sparsely clothed with nearly white, recumbent, 

 bifurcate scales, those on the last three abdominal segments being 

 suberect and some of them entire. Foretibia (fig. 18, c) each with 

 six rather large teeth on outer margin. 



Male. — Similar in size and habitus, but with the f rons concave for 

 entire width, thinly clothed with hairs, with abundant, coarser, 

 longer, fulvous hairs at sides; pronotum with posterior group of 

 asperities poorly developed; venter of last abdominal segment with 

 hairs directed laterally. 



This species is rather closely related to Pseudocryphalus maclayi 

 Bruck but differs in the absence of the frontal tubercles, in the nota- 

 bly stouter form, in the uniformly light-brown body color, and in the 

 very different color pattern formed by the scales. 



Type locality. — Southern California. 



Additional locality. — Catalina Springs, Ariz. 



Host. — Encelia farinosa A. Gray. 



Type materidl. — Holotype, allotype, and 12 paratypes, U.S.N.M. 

 No. 62950. 



Remarks. — Holotype, allotype, and 7 paratypes are from the 

 Coquillett collection, taken in San Bernardino County, Calif.; 1 

 paratype, labeled "Cal."; 1 specimen without data; 3 paratypes —

 Figures 17, e, f; 18, d 



Female. — Piceous black, clothed with cinnamon-brown and light- 

 cinereous scales; 1.45 to 1.8 mm. long; holotype 1.57 mm. long, 1.75 

 times as long as wide. 



Frons with epistomal margin ending in a sharp median point, with 

 a fringe of moderately long, rather fine, yellowish hairs, shorter 

 and sparser at middle, reaching nearly to tips of mandibles at sides ; 

 arcuately, transversely impressed above epistoma, with impression 

 widened and forming a subtriangular concavity extending to just 

 above eyes; surface piceous, shining, finely and closely granulate- 

 punctate, elevated and more strongly granulate at sides and above; 

 surface of concavity partly concealed by rather short, moderately 

 coarse, cinereous setae, which are longer and more abundant above 

 and at sides. Eye about 3.3 times as long as wide, finely granulate, 

 inner line shallowly, broadly emarginate. Antenna (fig. 17, /) with 

 club comprising nearly half of visible length, slightly more than 

 twice as long as wide, with three straight, annulate-setigerous 

 sutures, setae rather long and slender.
