finer than in Be/yragei. I'hc (ilih ventral segment ( c^ ) is deeply subpara- 

 bolically emarginate ; the sixth segment much longer than wide, slightly 

 narrowed to apex, which is broadly, not very deeply arcuately emarginate, 

 the lateral angles moderately acute, but not produced or incurved, their 

 points bent downward ; lateral cariniii very feebly arcuate, and only 



slightly convergent anteriorly, nearly reaching the base of the segment, the 

 surface between them rather coarsely punctate and subcarinate throughout 

 along the median line. Last dorsal notched at middle, the sides rounded; 

 penultimate dorsal broadly, deeply triangularly emargmate. Female as in 

 Belfragei. 



Length, 1 1-13 mm. 



The type is a male from Claremont, California, collected by Baker. 

 With tliis I have placed a second male collected by Schwarz at Oracle, 

 Arizona, and females from Pomona, Riverside, Echo AEt., and San 

 Jacinto Mt., in Southern California, and Harqua Hala, in South-western 

 Arizona. 



The elytral band is almost exactly at the middle of the elytra ; it is 

 very narrow on the disk, widening a little at the margin, and is frequently 

 obscure or visible only at sides. In Belfragei the sixth ventral is nearly 

 square, a little wider toward the apex, the lateral carinas shorter and more 

 convergent. 



Hydnocera plagifera, n. sp. — Very robust, black, slightly aeneous, and 

 moderately shining ; elytra each with a broad reddish-yellow stripe of 

 uneven width extending from the base to apical two-fifths, touching the 

 base and side margin, but not reaching the suture, the tips of the humeri 

 dark. Pubescence moderately plentiful, erect and subrecumbent, white, 

 mixed with black, and with a denser transverse fascia of white hairs 

 covering the dilated posterior end of the pale stripe. Antennae pale 

 yellow j eyes moderately large ; head densely, not coarsely, punctate. 

 Prothorax distinctly wider than long, nearly as wide as the head, including 

 the eyes, sides strongly dilated before the middle, straight and parallel in 

 apical two-fifths ; strongly impressed along the basal margin ; disk evenly 

 convex, median line smooth posteriorly, becoming evanescent in front, 

 elsewhere closely but not coarsely punctate, the sculpture becoming 

 somewhat rugulose laterally. Elytra covering the abdomen, plainly wider 

 than the head, almost three-fifths as wide as long, punctuation coarsr and 

 rather dense ; apices impressed before the margins, which are serrulate
