AMERICAN COLEOPTERA. 145 



Eyes and front nearly as in alutaceus; antennae slender, joints 2, 3 and 4 nearly 

 equal, the second stouter; 3 and 4 fully twice as long as wide (similarly propor- 

 tioned but stouter in alutaceus) ; 6 and 7 subequal, the latter just visibly the 

 longer, and each very slightly shorter than 2, 3 or 4 ; 8 shorter, as wide as long 

 or very nearly so ; 9 a little longer than the four preceding. Sixth ventral deeply 

 cleft ; tarsi more slender than in alutaceus. 



California. Collected by Crotch, near San Francisco if my 

 memory serves me. 



The specimen which forms the type of this species was placed 

 with the type of alutaceus in the LeConte collection, but though 

 there is a considerable resemblance between them I believe them 

 quite distinct. The type of Crotchii is certainly a male, the geni- 

 talia being exposed. 



8. E. gracilis Lee. — " Elongate, rufotestaceous, less shining, finely pubes- 

 cent, densely scabrotis-punctulate. Eyes moderate in size, very convex. Antenna? 

 half the length of the body, rather stout, joints 3-8 nearly equal in length, 5-8 

 wider than 3rd and 4th ; 9th as long as the five preceding united, 10th and 11th 

 each as long as the ninth. Prothorax more than twice as wide as long, sides 

 very much rounded and widely margined, concavity of the margin extending 

 along the base to a basal fovea, where it becomes narrower. Elytra convex, finely 

 margined." "Leugth 3.7 mm." 



"Garland, Colorado ; one male." 



LeConte's statements that joints 3-8 of the antennae are nearly 

 equal in length, and that the prothorax is more than twice as wide 

 as long are probably both incorrect, at least they do not at all apply 

 to any other species in our fauna and it is easier to believe an error 

 has been made in description than to imagine so great a deviation 

 from the prevailing type. 



Since the above transcription of LeConte's original description 

 and the remarks following were written, I have personally examined 

 the type at Cambridge and find the description to be in error as 

 suspected above. The prothorax is of the usual form and plainly 

 less than twice as wide as long. Joints 3, 5 and 7 of the antennae 

 are subequal, and 4, 6 and 8 are also subequal and a little shorter; 

 9 is not much longer than the four preceding. The front is about 

 twice as wide as the longest diameter of the eye ; the prothorax very 

 feebly, just visibly granulate; the sixth ventral broadly not deeply 

 emarginate. According to LeConte the type is a male; of this I do 

 not feel at all certain.
