4. Estola porcula, n. sp. 
E. oblongo-ovata^, iiispida, obscure brumiea, griseo confluenter macu- 
lata; anteniiis testaceo aimulatis ; eljtris antice confuse, postice 
sublineatim pimctatis, apice obtusis. Long. 2-Z\ lin. 
Head thickly punctured, blackish, clothed with coarse greyish 
pubescence and rigid hairs. Antenna dusky; fourth, sixth, eighth, 
and tenth joints ringed with pale testaceous. Thorax convex, 
thickly punctured, setose, and clothed with dull-greyish tomentum; 
lateral tubercles small, acute. Elytra oblong, scarcely narrowed 
behind, apex obtusely rounded ; surface closely setose, minutely 
varied with dingy grey and dusky brown, punctured, the punc- 
tures confused except towards the apex, where they are partly 
arranged in rows. Body beneath and legs dusky, clothed with 
coarse greyish pile.

Genus Epectasis., nov. gen. 
Body greatly elongated, narrow, cylindrical, clothed through- 
out with erect, fine hairs. Head small, face convex, vertex de- 
])i*essed between the bases of the anteiinse ; eyes reniform, rather 
distant on the crown. Antenna 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 joint 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 
antennse, both above and beneath, and the unarmed thorax. The 
insect known in collections under the MS. name of Euteles 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.

elytris grosse confuse pimctatis, prope apicern cinereo plagiatis, 
apice oblique valde truncatis. Long. 4 liii.
