California (Mendocino Co.). 



The small size, narrow form and complete absence of any scutellar 

 modification of the basal lobe of the pronotum, will readily distin- 

 guish this species from any Dryops known to our fauna. 



ELATERIDJE. 



ALAUS Esch. 



A. ZimiaTlllS n. sp. — Elongate, very convex, shining, black throughout, 

 the upper surface with sparse patches of dense yellowish-white squamiform 

 pubescence ; vestiture elsewhere less dense, black ; integuments finely closely 

 and distinctly punctate, the punctures larger on the prothorax, becoming 

 coarse and very dense anteriorly, the elytra with series of small but strong, 

 close-set punctures, the two or three series nearest the suture not coinciding 

 with the feebly impressed lines. Head impressed anteriorly, coarsely, densely 

 punctate, the punctures intermingled with finer punctules ; vestiture in great 

 part pale ; antennae scarcely extending to basal third of the prothorax, nearly 

 as in gorgops Prothorax scarcely as long as wide, parallel, broadly and dis- 

 tinctly arcuate at the sides, the ornamentation as in gorgops. Scutellum 

 abruptly more declivous anteriorly. Elytra as wide as the prothorax and 

 distinctly more than twice as long, the usual large black spot at the sides 

 well defined and bordered anteriorly by a large solid patch of the pale pubes- 

 cence. Under surface with some patches, more or less isolated, of pale pubes- 

 cence near the sides ; presternum longitudinally canaliculate between the 

 coxae. Length 33.0-44.0 mm. ; width 10.0-13.5 mm. 



Arizona. 



The three specimens before me represent a species allied to 

 gorgops, resembling that species especially in the large uneven 

 and isolated patches of pale pubescence, which are here still larger 

 and less numerous. Jt differs greatly in general form and sculp- 

 ture, the sides of the prothorax being nearly straight in gorgops, 

 with the elytra scarcely twice as long, and with the elytral punc- 

 tures very fine and sparse, the series composed of much smaller and 

 more remote punctures, and coinciding with the feeble impressed 

 lines. In zunianus the pronotum is finely but distinctly canalicu- 

 late along the middle, and the eye-like spots are more distant from 

 the edge and more approximate than in gorgops; the last segment 

 of the abdomen is devoid of pale vestiture in the three specimens 

 before me. 



Lusciosus Hope, with which gorgops is united by Candeze, is 

 stated to be shorter in form than oculatus ; this is distinctly true
