the neck, at which point it is strongly constricted on all sides. The 
elytra are proportionally more dilated near the apex than in 4. 
geniculata, and the sutural angle is much more produced, resem- 
bling in this respect 4.rufescens ; their surface is marked with im- 
pressed rows of distinct regular fovez, the bottoms of which have 
a slight brassy lustre, and the interstices both longitudinal and 
transversal are narrow, so that the surface appears almost reticu- 
lated. The legs are robust and shining black, except the middle 
part of the femora, which is yellow; the middle and hind tarsi 
are elongated, the basal joints being also elongated and slender. 
The antennz are shining black (apical joints wanting). 
Male.—Middle of metasternum and a space in the middle of 
the hind part of the three basal ventral segments punctured and 
pubescent. Anterior tarsi with the basal joint rotundate-dilatate ; 
middle tibize with a strong tooth within (and hirsute) near the 
apex ; posterior tibiz strongly bent inwardly in the middle and 
thickened and hirsute thence to the apex. 
This large and handsome species is from Peru; there is a 
single specimen only in Mr. Saunders’ Collection. 
Agra occipitalis. (Pl. XX. fig. 1, $.) 
A. nigra, thorace elytrisque zeneis, his certo situ subeupreo-mi- 
cantibus ; capite elliptico, ante oculos modice protenso, pone 
oculos valde elongato, vix attenuato; thorace angusto, grosse 
lineatim punctato ; elytris flexuoso-truncatis, angulis suturali- 
bus nullomodo, externis breviter, productis, supra lineatim 
foveolatis (haud striato-impressis ), foveolis interdum elongatis, 
fundo multipunctatis ; antennis pedibusque nigro-piceis. 
é tibiis posticis leniter incurvatis, a medio usque ad apicem 
intus dense hirsutis.

Allied to 4. merens, Chaud. (Ann. Soc. Ent. Fr. 1861, p. 119) 
and A. scrutatrix (ante, p. 370); the head is broader and less 
narrowed behind the eyes than in the ¢ of 4. merens, and the 
insect differs from both species in its brighter brassy colour, with 
faint coppery reflexions towards the apex of the elytra. The head 
is of an elliptical shape, and the part behind the eyes is much 
longer than the anterior part. The fovez on the elytra have no 
trace of lying in impressed lines as is the case with the species 
above quoted, and some of the fovez are elongated, with a few 
obscure bluish punctures at their bottoms. 
One example, from Brazil.
