16 JOUKNAL, OF ENTOMOLOGY AND ZOOLOGY 



joint in the male, the processes subequal in length to the joints them- 

 selves. 



Head and prothorax finely and sparsely punctured. Elytra 

 closely punctate. Claws with a small basal dilatation. 



Male: Antennse pectinate; elytra not at all swollen at tip, but 

 with a small shallow apical impression; front and middle tarsi dis- 

 tinctly dilated; oedeagus nearly as in abiwrmis. 



Female: Antennae subserrate, elytra not mociified at apex; tarsi 

 not dilated. 



Of this species I have seen only the three examples — 1 5,2$ — 

 in the LeConte collection. The species was described from the $ 

 only, taken by Crotch at Crystal Springs, San Mateo Co., Cali- 

 fornia, a few miles south of San Francisco. The two 9 's were 

 probably added later since in the original description the 9 is said 

 to be unknown and if this be the case it is quite possible that they 

 are not really crotchii. It is a little surprising that with all the 

 collecting done by Drs. Blaisdell and Van Dyke in the vicinity of 

 San Francisco, their collections contain no examples of this species, 

 unless perchance there be some unrecognizable 2 's. The $ may 

 be at once distinguished from all our other known species by the 

 pectinate antennae, but the ? must, I think, be very similar to that 

 of several other species.

 Trans. Am. Ent. Soc, 1874, p. 40. 



Length: 6}i to nearly 8 mm. Black, shining, elytra in the $ 

 normally more or less pruinose and dull; prothorax typically red, 

 more rarely black. 



Antenuie rather short and stout, moderately serrate, half as long 

 as the body or slightly more in the $ , scarcely half as long as the 

 body in the ? ; intermediate joints about J4 longer than wide. 



Head parallel behind the eyes; minutely remotely punctulate; 

 tempora and sides beneath sparsely finely punctate. 



Prothorax sparsely punctate. 



Elytra closely, rather finely punctate. 



Male: Elytra more shining than in the 9, not pruinose, apex 

 not modified. Four anterior tarsi dilated. Hind tibiae arcuate and
