densely punctured, middle line slightly smoother, a vague oblique impression 

 hehind the middle. Elytra a little wider than the thorax, oblong parallel, 

 narrowed at apical third, disc moderately convex and with rows of punctures 

 coarse at base gradually finer and more confused toward the tip, intervals with 

 a row of finer punctures. Body beneath more shining than above, moderately 

 densely punctate. Length .22 inch; 5.5 mm. 



Occurs in the White Mountains, New Hampshire, (Austin), and in 



Illinois, (Ulke). 



ElJRYPOGOl^ Motsch. 



This genus agrees in all respects with Macropogon except in the 

 structure of the antennse. The second joint is small oval, third 

 longer, the two together longer than the fourth, joints 4 — 11 slender, 

 subequal. 



Two species are known, distinguished as follows : 



Punctures of elytra coarse, intervals less wide than the punctures niger. 



Punctures fine, intervals broader californieus. 



E. niger Mels. — Oblong, black, shining, sparsely pubescent. Head very 

 sparsely punctate. Thorax one-half broader than long, slightly broader at 

 base, sides straight, disc moderately convex, sparsely coarsely punctate and 

 with traces of the oblique impressions posteriorly. Elytra a little wider 

 than the thorax, oblong parallel, with rows of moderately coarse punctures 

 closely placed, intervals with a row of fine punctures, surface with semi-erect 

 short black hair. Body beneath black, shining, sparsely punctate, logs piceous. 

 Length .16 — .18 inch; 4 — 4.5 mm. 



Occurs from Pennsylvania to Kansas. 



E. californicus n. sp. — Oblong, piceous, moderately shining, sparsely 

 pubescent. Head coarsely sparsely punctate. Thorax very nearly twice as 

 wide at base as long, narrower at apex, sides nearly straight, disc moderately 

 convex with broad vague depressions posteriorly, surface sparsely coarsely 

 punctate. Elytra a little wider than the thorax, oblong parallel, gradually 

 narrowing at apical third, surface with rows of moderately fine punctures not 

 closely placed, the intervals flat, much broader than the punctures and with a 

 single row of finer punctures, sparsely clothed with semi-erect, short, brownish 

 hair. Body beneath piceous, sparsely punctate. Legs and autennse brownish. 

 Length .18 inch ; 4.5 mm. 



Distinct from niger by the finer elytral sculpture and its more 

 elongate form. 



One specimen from the Geysers, California, given to Dr. Leconte 

 by Mr. C. Bolter. 



It is probable that the discovery of other species will show the 

 necessity of uniting this genus with Macropogon, 



AI.I.OPOGON n. g. 



Form and general appearance of Macropogon differing as follows : 

 Antennae serrate, not longer than half the body, first joint cylindric- 

 coniC; rather short, second short broader than long, third one-half
