and are very finely punctured. On each stria is a series of small 
black and whitish spots, and these most of them are oblong.

This species closely resembles the last in many respects, and espe- 
cially in its colouring, and in being covered with minute ashy-brown 
decumbent hairs, but it is of a narrower and more elongated form, 
and of a much smaller size. 
The rostrum is about half as long again as the head, rugose, and 
has three parallel keels on the upper surface, of which the central 
one is the most prominent. The head is thickly punctured. The 
thorax is scarcely one-third broader than long, slightly emarginated 
in front; the sides are nearly straight and parallel, but near the 
anterior part they gradually converge, so as slightly to contract the 
width of the thorax at this part; about the posterior third of the 
thorax the sides also converge towards the posterior margin, so that 
the thorax may be described as obliquely truncated on each side be- 
hind: the posterior margin is straight; the upper surface is nearly 
flat, and thickly and distinctly punctured. The elytra are moderately 
convex and of an elongated ovate form, and about half as broad 
again as the thorax; punctate-striated, the punctures of moderate 
size and distinctly separated, excepting on the hinder part of the 
elytra; they are densely clothed with decumbent ashy-brown hairs, 
and on each stria is a series of oblong blackish spots ; the interstices 
are very delicately but thickly punctured. 
Aproristus conspersus. Ad. niger, subopacus, fusco-pilosus ; an- 
tennis tarsisque fuscescentibus ; rostro brevi, crasso, carinato ; 
thorace punctatissimo, subquadrato, postice pauld angustiore, modice 
convexo, lateribus subrotundatis ; elytris quoad latitudinem thorace 
Sere coequalibus, lateribus subparallelis, punctato-striatis, intersti- 
tits planis.

Hab. Valleys of Petorca. : 
Rostrum about half as long again as the head, much dilated at the 
apex, with three distinct carine, and the two outer carinz converging 
slightly towards the base of the rostrum; between the carine are 
minute longitudinal ruge, but these are hidden by the numerous 
small brownish hairs which cover this and other parts of the insect. 
The head is thickly punctured, and there is a minute oblong depres- 
sion between the eyes. The thorax is subquadrate, about one-fourth 
broader than long; the anterior margin is straight; the sides are 
slightly rounded, but nearly straight towards the hinder part of the 
thorax ; the greatest width is at the anterior third; the posterior
