the sides of the face, disk of the meso- and metapleura, base of the first 

 ventral segment, a line on either side close to the base of the remaining seg- 

 ments, a cloud on each segment of the connexivum and a mark either side of 

 last ventral segment and the oviduct of the female black. Front more or less 

 ferruginous. Knees and apex of the tarsi above touched with black. Elytral 

 nervures pale to beyond the node, infuscated at apex. The hyaline portion 

 of the elytra slightly fuliginous, the basal areola subopaque, fuscous. Male 

 uncus much like that of noveboracensis but a little broader and more convex 

 below toward the apex. 



Described from four examples taken by Dr. E. C. Van Dyke; one 

 pair captured at Carrville, Trinity Co., Calif., June 29, 1913, two males 

 from Nash Mine, Trinity Co., June 29, 1913, at an altitude of 8,000 

 feet, and one male taken by Mr. Nunenmacher in Plumas Co. in June 

 and now in the collection of Mr. Davis. 



It affords me pleasure to name this distinct species for its dis- 

 coverer who has long been known as one of the most active and 

 efficient entomologists on the coast, a close student of the Coleoptera 

 and perhaps our best authority on the ecology and distribution of the 

 west American insect fauna.

This pretty species resembles consohrina but it is smaller with the 

 surface more polished, the colors clearer, the pale markings more 

 extended and the surface less densely clothed with pale scale-like 

 hairs. The male genital characters scarcely differ from those of 

 vanduzeei of which it may be but a variety. Thus far it has been 

 taken onh- south of the Tehachapi.

x'Vs I determine this species it is very close to californicus but is 

 more strongly narrowed anteriorly, the head is narrower (3 by 5 

 mm.), the front is more produced above and mostly black, the prono- 

 tum is black margined all around with pale and sometimes with pale 

 marks in the lateral depressed lines, the venter is pale and im- 

 maculate, the mesonotum wants the pale marks at the apex of the 

 loop and sometimes those at the anterior angles of the X. The male
