BEETLES OF THE GENUS RENOCIS — BLACKMAK 383 



"arrowhead-shaped" spot, and in a smaller, irregular-shaped spot at 

 each side involving both groups of asperities; anterior margin with 

 very sparse fringe of lighter brown, erect setae. 



Elytra 1.28 times as long as wide, slightly wider than pronotum; 

 sides subparallel on anterior two-thirds, broadly rounded behind; 

 each basal margin strongly elevated from first to fifth interspace, 

 with 6 coarse crenulations, very coarse nearest suture; striae dis- 

 tinctly but rather weakly impressed, with punctures moderate and 

 fairly close; interspaces nearly flat, finely rugose punctate; surface 

 nearly concealed by numerous small, rather narrow, semirecumbent 

 scales, some of them brown and some very light cinereous ; light scales 

 forming the usual sutural stripe, and two broad fasciae, one in an- 

 terior half of elytra, the second involving entire face of declivity; 

 each interspace with a median row of erect, broad, spatulate setae, 

 brown or cinereous in color; each elytron with a dense group of erect 

 brow setae just behind the basal elevation. Declivity moderately 

 steep, very broadly sulcate between third interspaces, first and second 

 interspaces flat, nearly devoid of erect median setae ; third interspace 

 rather high, with median erect setae more numerous than on disk, 

 forming a partial double row. 



Ventral surface dark brown, shining, sparsely clothed with white, 

 recumbent, bifurcate scales, which are suberect on last three ab- 

 dominal segments. Foretibia with six rather long teeth on outer 

 margin. 



Tyfe locality. — ^Los Angeles County, Calif. 



Host. — Eihcelia calif ornica Nuttall. 



Type material. — Holotype in collection of C. R. Bruck. Para- 

 types: Collection of California Academy of Sciences, San Francisco, 

 Calif. ; Canadian National Collection, Ottawa, Canada ; Los Angeles 

 Museum ; collection of A. T. McClay. 



Remarks. — The foregoing description was prepared from a para- 

 type of Pseudocryphalus maclayi Bruck loaned by the Los Angeles 

 Museum through the courtesy of Dr. John A. Comstock and Dr. W. 

 Dwight Pierce. The paratype bears the data "Westwood Hills, L. A. 

 Co. Cal., 1.26.1936; Encelia calif ornica; A. T. McClay, Collector/' 

 From comparison with other species of Renocis it is believed that 

 this paratype is a female. ISTo other specimens have been seen by the 

 writer. 



RENOCIS PRUINOSUS, new species 



FiGTJEEs 17, d; 18, c , 



Female. — Light reddish brown, but appearing pruinose owing to 

 light-cinereous scales; 1.8 to 2.25 mm. long; holotype 2.14 mm. long, 

 1.85 times as lone: as wide.
