CRYPTORRHYNCHUS. 641 
Species small, subovate, very densely squamose and coarsely setose, with the rostrum feebly 
arcuate, the antenne inserted near its tip, the antennal club acuminate-ovate, the eyes 
distant, the prothorax bisinuate at the base, the elytra very little wider than the prothorax, 
comparatively short, the mesosternum broad, prominent, shallowly emarginate, the 
metathoracic episterna moderately broad, the ventral segment 2 longer than 3, the femora 
unidentate, the anterior tibiz and tarsi not ciliate in the male. (No. 14.)

Hab. Mexico, Playa Vicente in Vera Cruz (Sal/é).—Cotompzia 1. 
A single specimen ( ¢ ) from Mexico agrees very well with another before me from 
Colombia. In this insect the vestiture is very dense above and beneath, and in great 
part white. The elytra have a common, arcuate, blackish fascia at the middle of the 
disc, and a similarly-coloured streak on each of the third and fifth interstices below 
the base; the interstices 2, 3, and 5 are raised. The antenne are inserted near the 
tip of the rostrum. The second joint of the funiculus is elongate, as long as the first. 
The anterior tarsi are without projecting hairs. The femora are each unidentate. 
The only important character it has in common with Gasterocercus is the broad, 
shallowly emarginate mesosternum. 
Species small, oblong-ovate, densely squamose and setose, with the rostrum short, a little 
widened towards the base and apex, and almost straight, the eyes distant (small in 
C. curtirostris), finely facetted, the antennal club ovate, the prothorax bisinuate at the base, 
with rather prominent ocular lobes, the scutellum small, the elytra wider than the 
prothorax, with the second or third interstice raised at the base, the mesosternum 
prominent, feebly arcuate-emarginate, the metathoracic episterna moderately broad, the 
ventral segment 2 a little longer than 3, the femora unidentate. (Nos. 15-17.) 
The more finely facetted eyes and the strongly setose upper surface separate these forms 
from Semnorrhynchus. 
15. Cryptorrhynchus spiculosus, sp.n. (Tab. XXXI. figg. 21, 21a, 3.) 
Oblong-ovate, black, the antenne and tarsi ferruginous; densely clothed above and beneath with whitish 
scales, the prothorax with a broad space on the disc behind (divided down the middle and surrounding 
two triangular black basal spots), and the elytra with the base and apex, and an interrupted, outwardly 
widened, common, median fascia, more or less brown, the elytra also with a streak on the second 
interstice at the base, and some other markings, black, the femora and tibie annulate with dark brown ; 
the upper surface set with scattered, coarse, blunt, erect, light and dark sete, which on the elytra are 
mainly concentrated on the alternate interstices, the legs setose. Head densely punctate, the eyes rather 
large, finely facetted, widely separated ; rostrum short, stout, slightly widened towards the base and 
apex, feebly curved, rugosely punctate, in the 2 more finely punctured, the antenne inserted behind the 
middle, joints 3-7 of the funiculus short, 2 shorter than 1, the club stout, ovate. Prothorax transverse, 
abruptly constricted and much narrowed in front; densely, finely punctate. Elytra wider than the 
prothorax, subparallel in their basal half; punctate-striate, the interstices closely punctulate, 2, 4, and 6
