CERAMBYCID/E 279 



In fact, some of the forms placed near the head of the Lamiinse by 

 LeConte and Horn, such as Cyrtinus and Psenocerus might better 

 be transferred to the Clytini, where the type species were originally 

 placed by Haldeman and Say respectively. The species described 

 by the writer as Psenocerus tristis, afterwards suppressed by Hamil- 

 ton, is by no means the same as supernotatus or even a subspecies; 

 it is abundantly distinct in outline, structure and habitus and should 

 be rehabilitated. There is another species of the genus in my collec- 

 tion from Tamaulipas, Mex. 



Tribe DORCADIONINI. 

 Ipochus Lee. 



This is one of the very few American types representing the 

 extremely numerous and diversified Dorcadion and Parmena of the 

 old world; it is a very local development, confined to the coast 

 regions of southern California and is moderately rich in species; 

 it is allied very closely to Parmena, differing almost solely in the 

 absence of lateral thoracic prominences; the type of elytral vesti- 

 ture seems to be the same in both. The species in my cabinet may 

 be recognized as follows: 



Elytral punctures simple; last ventral segment of the male broadly 

 arcuato-truncate and simple at apex 2 



Elytral punctures more or less evidently asperate; last ventral strongly 

 margined medially at apex in the male 7 



2 Prostrate hairs of the elytra long and usually denser 3 



Prostrate hairs very much shorter and generally distinctly sparser. . . .4 



3 Fasciae of the elytra white, narrow; vestiture of the prothorax not 

 conspicuously dense, having the four small clusters of ; white hairs 

 very distinct; body rather narrow, very convex, the elytral humeri 

 moderately impressed; antennae as long as the body; erect hairs 

 very numerous, white and blackish intermingled. Length (cf) 6.5 

 mm.; width 2.1 mm. California (near San Diego), Ricksecker. 



hispidus n. sp. 



Fasciae yellowish, the posterior very broad, equalling nearly half the elytral 

 length, its anterior limit sharply biserrate, the subbasal fascia 

 narrow; vestiture of the prothorax very dense, pale brown and con- 

 spicuous, the four pale points evident; antennae (9 ) nearly as long 

 as the body, gradually and feebly tapering; erect hairs relatively 

 less abundant than in the preceding; prothorax decidedly transverse, 

 not as wide at base as at apex. Length (9) 8.0 mm.; width 3.3 

 mm. California (near San Diego), Dunn pubescens Csy. 



4 Prothorax (9) rather strongly transverse, somewhat hexagonal, the 

 sides being very broadly angulate medially; body piceous in color,
