FALL AND COCKERELL. 223 



flattened along the median line, punctuation moderately close and rather fine, 

 the punctures tending to coalesce in short rugffi toward the anterior angles. 

 Elytra almost exactly equal in length to the head and prothorax united ; punc- 

 tures between the costffi very fine but usually evident. No sexual differences 

 are detectable in the numerous examples seen. Length 2.5-3.3 mm. 



This is the species referred to as grandiceps in my list of the 

 Coleoptera of Southern California. The latter species was described 

 from Pennsylvania, and is quite surely distinct if correctly defined 

 by Casey. The five species now known to us may be separated as 

 follows : 



Median apical process of epistoma bifid at apex. 



Head longitudinally strigose or aciculate, and more or less evidently longer 

 than the prothorax. 

 Antenna scarcely as long as the head ; nuchal constriction distant from the 

 eye by nearly twice the length of the latter, elytra shorter than the 



head and prothorax together (Pennsylvania) grandiceps. 



Antennae plainly though not greatly longer than the head ; nuchal constric- 

 tion distant from the eye by less than one and one-half times the 

 diameter of the latter; elytra equal in length to the head and thorax 



together (Southern California) striaticeps. 



Head not strigose and shorter than the prothorax ; elytra longer than the head 



and prothorax together (Middle California) simulator. 



Median apical process of epistoma truncate or subtruncate at apex. 



Head subequal in length to the prothorax ; elytra longer than the head and 

 prothorax together; punctuation very fine (New Mexico). 



inonticola. 



Head shorter than the prothorax ; elytra equal in length to the head and pro- 

 thorax together; punctuation stronger (Florida) breviceps. 



NrriDULIDiE. 



Epuriea alticola n. sp.-Broadly obtusely oval, pale rufotestaceous, shin- 

 ing sparsely pubescent. Head moderately punctate, the punctures separated by 

 about their own diameters. Anteunte rufotestaceous, club slightly darker ; third 

 joint scarcely twice as long as wide, fourth and fifth equal and slightly longer 

 than wide, sixth as wide as long, seventh and eighth transverse, the latter strongly 

 so; club broadly oval, its first and last joints subequal in length, each about two- 

 fifths the entire length of the club ; antennal grooves confluent behind, not very 

 sharply impressed. Thorax about twice as wide as its length on the median line, 

 widest a little before the ba.se, sides thence broadly arcuate and convergent to 

 apical angles; j.ust visibly sinuate before the hind angles, which are sharply de- 

 fined and slightly obtuse; disk evenly not very closely punctate, side margins 

 rather broadly reflexed. Elytra scarcely one-sixth longer than wide, sides feebly 

 arcuate apex broadlv truncate and subequal in width to the base, side margins 

 rather narrowly reflexed; punctuation similar to that of the head and thorax. 

 Beneath moderately closely punctate ; intercoxal process broad, obtuse. Length 

 2.5 mm. ; width 1.5 mm.
