424 HETEROMERA. 
“ Elongata, opaca, nigra, pube grisea densissime vestita, marginibus elytrorum tenuissime albo pilosis ; antennis 
basi rufis.—Long. 17, lat. 4 millim. ¢ tibiis omnibus subcurvatis, articulo primo tarsorum anteriorum 
majore, dense spongioso.” 
I have not seen an Lpicauta answering to this description, which seems to be based 
upon a single specimen. The colour of the antenne is of little value as a specific 
character.

Not uncommon in the State of Vera Cruz, whence we have received upwards of fifty 
examples. . obesa may be known from the allied uniformly cinereo-pubescent species 
by the strongly setaceous antenne in the male sex, joints 3-6 moderately thickened, 
and 4 and 5 together not much longer than 3, 1 comparatively short; in the female 
joints 3-6 are more slender, 4—6 more elongate. The pubescence is fine and not very 
dense. The anterior tibie have two spurs in the male; the outer spur of the hind 
pair is stouter than the inner one. The head and thorax are closely, finely punctate, 
the epistoma and labrum more coarsely and sparsely so. 
Lytta mus, Haag, to judge from a specimen ( 2 ) from Orizaba (determined by Haag 
himself) before me, is inseparable from E. obesa. 
42. Epicauta auricomans, (Tab. XIX. figg. 22,¢; 22a, antenna, ¢ .) 
Moderately elongate, black, above and beneath densely, uniformly clothed with rather coarse golden or 
cinereous pubescence ; the legs yellowish- or cinereo-pubescent, with the tips of the femora and tibie and 
the tarsi entirely piceous or black. Head closely, finely punctate, coarsely so in front, and with a fine 
median groove, the labrum feebly emarginate; antenne black or piceous, setaceous, moderately long, 
joints 3-6 stouter in the male than in the female, 3 very elongate, much longer than 1, the latter com- 
paratively short ; prothorax subquadrate, with the sides rounded and converging in front, punctured like 
the head, and with a fine median channel ; elytra wider than the prothorax in both sexes, very finely 
scabrous-punctate ; legs piceous or black, long and stout; the spurs of the hind tibie rather stout, sub- 
equal; the tibie slightly curved, the hind pair in one example strongly and sinuously bowed inwards, 
and the anterior pair with two spurs, in the male. 
Length 11-14 millim. (¢ 9.)

Eleven examples. Closely allied to E. obesa, Chevr., and with the antenne formed
