and even between tlic carina and the hind angle the punctua-

 striate, interstices finely punctured, apices minutely infuscate ; 

 the antenna? black, third joint obconical and larger than the

Atcr, nitidus, nigro- vol griseo-pubescens ; capite conferiim punc- 

 tate ; thorace parum angustato, anticc lateribusqiic fortius et

L. 10-U mill. 



Densely black, shining, with black or griseous pubescence, 

 grey when the insect faces the eye and reversely black ; the 

 liead evenly, rather densely, and somewhat coarsely punc- 

 tured ; the thorax narrowest in front and gradually widening 

 to base, punctures on the disk rather fine, not closely set, ante- 

 riorly and on the lateral border the punctures are rather strong 

 and much more dense, and behind the eye the punctures are 

 obscurely ocellate ; the elytra bright red, punctate-striate, 

 interstices convex, finely punctulate, interstices 2, 3, 5 wide, 

 especially the third; the antennae — third joint obconical, 

 larger than the second, and with the legs densely black, claws 

 reddish. 



Differs from E. canah'coUis in the punctuation of the thorax

Elater miles, sp. n. 



Ater, nitidus, subrobustus, nigro- vel griseo-pubescens ; thorace 

 parum lato, in medio subtiliter, ad angulos parum dense, punc- 

 tate ; elytris coccineis ; antennis pedibusque nigris.

This species is extremely like E. pumiceus ; the thorax is 

 more convex and much broader, especially in the middle, with 

 an opalescent tint ; the elytra are feebly rugose and relatively 

 shorter ; the tarsi are more robust and the third joint of the 

 antenna longer and less obconical.
