collected in the Indian Islands by My. A. R. Wallace. 141 
small, flattish granules in front; prothorax short and very transverse, 
much contracted behind, the sides rounded, closely fringed with stout, 
stiff setee; scutellum very small but distinct; elytra ovate, contracted 
at the base, rounded at the sides, the squame arranged in lines; body 
beneath dark brown, closely punctured; legs and antennee ferruginous. 
Length 13 line. 
A much narrower insect than the last, the elytra more rounded at 
the sides, &c. In both the scales or sete are arranged in rather 
numerous lines on the elytra. 
Minthea similata. 
MM. brunnea ; capite lateribus integris ; prothorace medio depresso ; elytris 
vage seriatim squamosis. 
Hab. Saylee. 
Reddish brown; head broadly triangular with greyish scales, the 
sides entire; prothorax somewhat broader than the head anteriorly, 
narrower behind, depressed in the middle, with scattered greyish scales; 
scutellum minute; elytra a little broader than the prothorax, with 
greyish erect scales arranged in a few distant but very distinct rows ; 
body beneath reddish brown, finely punctured ; legs and antennz red- 
dish brown. Length 1 line. 
The characters of Minthea are given at page 97 of this volume. 
The species there described from the Amazons is exceedingly like the 
present, differing principally in the longer terminal joint of the an- 
tenne and more convex prothorax. 
Minthea dentata, (Pl. VII. fig. 10.) 
M. fulvo-brunnea; capite lateribus tridentatis; elytris subtiliter squa- 
mosis. 
Hab. Xulla. 
Pale reddish or fulvous brown; head broadly triangular, the side above 
and below the eye terminating in three large recurved teeth; prothorax 
broader than the head, covered with small, erect, greyish scales ; elytra 
slightly broader than the prothorax, rather closely covered with small 
greyish scales not arranged in definite lines ; body beneath finely punc- 
tured; legs and antenne yellowish ferruginous. Length 1} line. 
A very remarkable species on account of the singular toothed sides 
of the head; the first of these teeth is directly above the eye, the 
two others occupying the rest of the space below it. In Minthea 
similata the club is about a quarter of the entire length of the an- 
tenna, in this species it is at least a third of the length.
