 A. delicatulus, Lee., Ann. Lye. 5, 117 lis. 



A small (.17 inch) insect, with brownish head and thorax and black elytra. The 

 thorax and head are continently punctured, the elytra punctured in striae. The eye- arc 

 almost entirely divided. The under surface and legs are ferruginous. Occurs at Valle- 

 cito (Leconte), and in Owens' Valley, where many specimens were found under stones. 



TRIBE XII — NTCTOPORINI. 



Mentum moderate, supported by a short broad gular peduncle, ligula hardly visible, 

 base of maxilla* exposed, genae very prominent. Anterior tibiae slender, spurs small on 

 all the legs, tarsi silky pubescent beneath.

 Nyctoporis, Esch., Zool. Atl. IV. p. 11. 



This genus, only one of the tribe, is remarkable for the vestiture of its tarsi. Its spe- 

 cies appear to be confined exclusively to maritime California, and to the region of the 

 Coast Range. 



Our species are four in number, as follows: 

 I lead strongly carinate. 



Thorax with two deep foveae. cristata. 



ga 1 e a t a . 

 Thorax not idveate. car in at a. 



Head not carinate; thorax not foveate. aequicollis. 



X. cristata, Esch., Atlas Heft. IV. p. 11, a very ran- species. Length .50 inch. 

 N. galeata, Lee, Pacif. R. R. Rep. IX. Append. I. p. 19, pi. 2, fig. 1. 



This species is closely allied to the preceding, and it is very doubtful whether they are 

 distinct. A typical specimen of cristata is in the collection of Dr. Leconte, and we are 

 thus enabled to make perfect comparisons. In both species the elytra are ornamented 

 with acute ridges interrupted, forming rather a s ( . r i,.s of short elevations or catenulations. 

 The only essential difference between the two species appears to lie in these ridges. In 

 cristata they are rather longer, less acute on top and higher than in galeata. The two 

 forms thus appear to differ strikinglj at first sight, hot an analysis slums but little of spe- 

 cific value, and it is highlj probable that other forms from the northern portion of Cali- 

 fornia will unite the two. Found abundantly near San Francisco. 



Length .50 inch.
