294 Mr. H. W. Bates on the Longicorn Coleoptera 
tures confused except towards the apex, where they are partly 
arranged in rows. Body beneath and legs dusky, clothed with 
coarse greyish pile.

Genus EPecrasts, nov. gen. 
Body greatly elongated, narrow, cylindrical, clothed through- 
out with erect, fine hairs. Head small, face convex, vertex de- 
pressed between the bases of the antennz ; eyes reniform, rather 
distant on the crown. Antenne as long as the body, filiform, 
clothed both above and beneath with long and fine hairs; basal 
joint short and thick, but narrowed at the base ; third jot con- 
siderably shorter than the fourth, the following joints gradually 
and successively shorter. Thorax elongate, cylindrical ; lateral 
tubercles nearly obsolete. Elytra elongated, cylindrical, apex 
obliquely truncated. Legs short; thighs scarcely clavate, basal 
joint of the posterior tarsi cylindrical, as long as the second and 
third taken together; claws semidivergent. Sterna narrow, 
plane. 
The chief points of distinction between this genus and the two 
preceding are the elongated cylindrical form of body, the hairy 
antenn, both above and beneath, and the unarmed thorax. The 
insect known in collections under the MS. name of Huteles lurida, 
might be included in it, as it offers most of the characters, with 
the exception of the fourth antennal joint not exceeding in length 
the third. 
Epectasis attenuata, nu. sp. 
EZ. elongata, cylindrica, hirsuta, obscure castaneo-fusca; antennis 
piceo-rufis, articulo terminali dimidioque penultimi pallide testa- 
ceis; thorace crebre punctato, medio late cinereo-fusco vittato ; 
elytris grosse confuse punctatis, prope apicem cinereo plagiatis, 
apice oblique valde truncatis. Long. 4 lin. 
Head small ; face convex, hairy, and clothed with dingy-greyish

of several preceding joints also greyish. -'Thorax cylindrical, elon- 
gate, sides slightly conical in the middle; surface closely punc- 
tured, dull blackish castaneous, middle with an obscure dull- 
ashy vitta. Hlytra elongate, cylindrical, hirsute, covered with 
large punctures, dull chestnut-brown ; apex with a greyish patch 
and obliquely truncated. Body beneath and femora blackish, 
tibie and tarsi reddish, hirsute, and clothed with dingy-ashy 
pubescence.
