Table of species of Epicserits. 



A. Scutellum small, triangular. 



1. Frontal fovea round or very shortly oval and not merging into a sulcus. 



a^. Elytral atrial punctures very large, much wider than the intervals; beak 

 medianly broadly impressed, subsulcate; pronotal punctuation minute, with 

 few large depressions, median line broadly impressed; scales rusty in color 



mexicanus Bohemaai. 

 a-. Elytral intervals at least as wide as striae. 



¥. Beak smooth on median line, but with two broad sulci at sides; frontal 

 puncture round, small, or moderate. Strial punctures round, deep and 

 almost as wide as the intervals; all funicular joints longer than wide, 

 seventh joint shortest; elytral vestiture distinctly iasciate. imbricatus Say. 

 b^. Beak broadly impressed on median line; fourth, fifth, and sixth funicular 

 joints about as wide as long, moniliform; seventh longer; elytral vesti- 

 ture unicolorous, grayish wickhami, new species. 



2. Frontal fovea elongate, merging into frontal sulcus of beak. 

 a^. Funicular joints elongate. 



¥. Very large species (16 mm.), elytra not more than one-half longer than wide; 



prothorax shallowly impressed along middle lucanus Horn. 



6^. Smaller species (under 10 mm.); elytra almost twice as long as wide; pro- 

 thorax medianly sulcate texanus Casey. 



a'-. Funicular joints 3-6, about as wide as long. 



c^. Elytra from one-half to two-thirds longer than wide. 



d^. Seventh funicular joint evidently longer than sixth; median line of 



prothorax sulcate ; length 8-10 mm sidcatus Casey. 



d^. Seventh funicular joint hardly if any longer than sixth ; median line 

 hardly indicated; elytra about one-half longer than wide; length 



4.5-6.5 mm lepidotus Pierce. 



c^. Elytra but slightly longer than wide formidolosus Boheman. 



B. Scutellum transverse, broadly oval; frontal fovea small, round; beak smooth on 



median line; funicular joints elongate, seventh shortest; vestiture fasciate 



benjamini, new species. 



EPICSIRUS IMBRICATUS Say. 



This species while quite variable in form, due to the inflation of the 

 abdomen in the female, nevertheless has a facies different from any 

 of our other species. Typical specimens are at hand from Washing- 

 ton, District of Columbia; Travilah and Locust Grove, Maryland; 

 Sharpsburg, Virginia; Catoosa, Georgia; St. Louis and Sedalia, Mis- 

 souri, and Tonganoxie, Kansas (T. B. A.). A series of smaller indi- 

 viduals with somewhat smaller strial punctures is at hand from 

 Arkansas (taken on strawberry, June 11), and Texas. Another simi- 

 lar series is at hand from Nebraska. Western Kansas and Texas 

 forms frequently are almost unicolorous, gray. 



EPICffiRUS WICKHAMI, new species. 



Described from eight specimens from New Mexico, collected by 

 Professor Wickham, in whose honor the species is named. One speci- 

 men from the Continental Divide of New Mexico (Townsend), two 

 from Colorado, and one from Wasatch, Utah, June 27 (Hubbard and 

 Schwarz) are also at hand.
