This fine species, the type (2) of which I have seen, approaches the Antillean 
LE, quadrivittatus, Oliv., the type of the genus; but it has the head shorter and the 
elytra less lobed at the base, the depressed dense patches of ochreous or whitish scales 
on the latter arranged into interrupted arcuate or angulate fascie and a common 
transverse scutellar spot. The scape of the antenne is widened from near the base 
and setose; the rostrum has a broad smooth space down the middle; the prothorax is 
feebly canaliculate and transversely depressed at the base, bivittate, the bare portion 
in some specimens coarsely punctate and in others almost smooth; the seriate 
punctures on the bare portions of the elytra are coarse and deep ; the small scattered 
scales on the legs, apex of elytra, and rostrum are usually green or blue; the tibia 
are feebly denticulate towards the apex; and the body is winged. Most of the 
examples seen are females, the male being narrower and less widened posteriorly. 
2. Exophthalmus fasciatus, sp.n. (Tab. XI. fig. 4, 3.) 
Prepodes fasciatus, Jekel, in litt. 
Exophthalmus princeps, Chevr. in litt. 
Oblong, robust, broad, somewhat shining, black or nigro-piceous; the head, rostrum, prothorax, scutellum, 
basal margin of elytra, and legs thickly clothed with narrow whitish scales; the elytra with a large 
transverse humeral patch, two common transverse fascie (the anterior one extending forwards for some 
distance along the suture), and a large spot at the apex, clothed with black, and the rest of the surface 
with imbricate, white or brownish-white, scales; the surface also set with rather long, scattered, bristly 
hairs, which are semierect on the elytra; the lower surface thickly clothed with white scales intermixed 
with scattered adpressed hairs, the legs also pilose, the tibie setose. Head and rostrum closely, finely 
punctate, the rostrum considerably longer than broad, sharply carinate down the middle, and with a fine 
oblique carina towards the sides, the inter-ocular fovea deep; antenne with a rather stout funiculus, 
joint 2 scarcely so long as 1, the scape slender, clubbed at the tip, not reaching the posterior margin of 
the eyes, the latter prominent. Prothorax transverse, obliquely narrowed anteriorly, sinuate at the sides 
behind, bisinuate at the base, narrowly sulcate down the middle; with scattered irregular confluent 
fovese intermixed with a fine interstitial punctuation. Scutellum rather large. Elytra broad, oblong- 
subtriangular in ¢, widened to the middle in 2, broadly depressed along the suture at the base, the 
humeri moderately prominent, the apices dentiform, dehiscent in 2 ; with twelve rows of coarse, deep
