In the very greatly magnified representation the antennae are much 

 too short. The detached figure in front of the head is the maxillary 

 palpus, the penultimate joint being concave to receive a corresponding 

 convexity of the terminal joint.

This genus is the only one in our fauna with the elytra so abbrevi- 

 ated as not to cover the greater part of the abdomen. Our species are 

 found along the California sea coast, and may be known as follow* : 



Body entirely ferruginous. 



Elytra opaque black, basal margin ferruginous b:es;alis. 



Body almost entirely black; thorax ferruginous; elytra black. 



Head, antenna? and legs ferruginous ab ilominalis. 



Head, antennse and legs black oollaris. 



E. basalis, Lee. (Ateksius) Proc. Acad. 1853, 168. 



This species is entirely ferruginous except the elytra which are 

 opaque, nearly black, with the basal margin ferruginous and some- 

 times a narrow sutural and lateral space of the same color. Length 

 .14 inch ; 3.5 mm. 



E. abrtominalis, Lee. loc. cit. 



In this species the abdomen, under posterior of body and elytra are 

 black, the head, thorax, antennae and legs ferruginous. It otherwise 

 resembles the preceding. Length .1 1 inch ; 3.5 mm. 



E. collaris. Lee loc. cit. — Head, antennae, legs, elytra and abdomen black. 

 Thorax red and more shining and usually broader than in either of the pre- 

 ceding species, with which it otherwise agrees in form. The black color has a 

 slight tinge of blue. Length .14 — .22 inch; 3.5 — 5.5 mm. (The latter measure- 

 ment is that of an unusually large female.) 



The genus Endeodes may be known by its short elytra, apterous 

 body, five-jointed tarsi, the anterior pair rather shorter than usual and 

 the second joint % prolonged aver the third, as in Attains, and con- 

 cave beneath. They were originally described as Atelestus.

Tarsi all five-jointed, simple in both sexes. Head short, antennaj 

 inserted nearly between the eyes. 

 Our species may be thus arranged:
