412 HETEROMERA. 
14. Epicauta evanescens. 
Moderately elongate, black or blackish-brown, the head and prothorax shining, the elytra opaque; finely, 
sparsely pubescent, the pubescence not hiding the sculpture, in great part cinereous, that on the elytra 
variable—black or purplish, or with intermixed cinereous hairs, the base, suture, and apex rather broadly, 
and in one specimen the sides also, indeterminately cinereous; the under surface very sparsely cinereo- 
pubescent. Head rather coarsely, closely punctate, with an indistinct median groove and the usual fulvous 
streak between the eyes, the latter large and somewhat prominent, the labrum rather deeply emarginate ; 
last joint of the maxillary palpi (¢) elongate, obliquely truncate at the tip; antenne black (obscure 
ferruginous in one specimen), subfiliform, becoming a little thinner towards the tip, moderately long, stout, 
joints 1 and 3 about equal in length, 2 short, 4-10 subequal, much shorter than 3, 11 a little longer 
than 10; prothorax campanulate, slightly dilated at the base, fully as long as broad, closely, rather coarsely 
punctate, with a smooth, well-marked median groove; elytra moderately long, subparallel, finely scabrous- 
punctate; legs stout, black or blackish-brown, the spurs of the hind tibie equal; anterior tibiee with a 
single spur in the male. 
Length 103-14 millim. (¢ 9.) 
Hab. Guatemata, Champerico (Champion). 
Two males and one female, from the vicinity of the Pacific coast. ‘This obscure 
species is perhaps nearest allied to #. unicalcarata, from which it differs in the coarsely- 
punctured head. The filiform, shorter antenne, the more campanulate thorax, the 
latter with sharply-defined median groove, and the less elougate shape distinguish 
E. evanescens from E. cinereiventris, which has a variety with the apex of the elytra 
cinereous. It is probable that the elytral pubescence may vary in colour to entirely 
cinereous; the three specimens obtained have it as described above.

Hab. Mexico, Guanajuato (Dugés1, Sallé), Michoacan (Dugés *). 
We have received one female and two male examples of this species. H. horni 
chiefly differs from its allies by the fine punctuation of the head and thorax. The 
antenne are moderately long and filiform, not thinner towards the tip. The anterior 
tibie have a single spur in the male. The pubescence above and beneath is uniformly 
cinereous and rather dense. Dr. Horn (Trans. Am. Ent. Soc. xii. p. 107) remarks that 
“ E. vicina belongs to the series with filiform antenne, and is most closely related to 
E. sericans, Lec.” ; the antenne, however, are much more elongate, the joints less 
closely articulated. JLytta vicina, Haag (1880), from Brazil, is an Hpicauta, and 
Dugés’s second name, vicina, as well as his first, cinerea, is preoccupied. 
16. Epicauta unicalcarata. 
Elongate, narrow, subparallel, black, opaque, above and beneath sparsely uniformly clothed with fine cinereous 
pubescence. Head finely, sparsely, shallowly punctate, with a faint median line and a longitudinal 
fulvous streak in the middle between the eyes, the latter large and deeply emarginate, the labrum feebly
