HOPLOCOPTURUS. 55 
anteriorly by an arcuate ridge. Legs rather elongate, femora bidentate beneath (the outer tooth small), 
the posterior pair carinate externally and extending beyond the apex of the elytra, the intermediate and 
posterior knees spinose. 
Length 63, breadth 3 millim. 
Hab. Nicaracua, Chontales (Belt). 
One specimen. . Very like Copturus quadricinctus, but a little more elongate, and 
with longer legs, the prothorax 5-vittate, the elytra deeply striate, the interstices not 
costate, the abdomen with a broad almost bare space down the middle, the femora 
bidentate, the posterior knees with two sharp spines, the mesosternum with a trans- 
verse, semicircular depression. 
4. Hoplocopturus nubilus, sp. n. (Tab. IV. fig. 6.) 
Subelliptic, moderately long, brown, the antenne ferruginous ; rather sparsely clothed with narrow scales: the 
head with a line around the eyes, and the prothorax with an oblique vitta on each side and a less distinct 
median stripe, ochreous, the elytra with a quadrate patch at about the middle of the suture, the suture 
narrowly at the apex, and numerous indefinite spots or markings, ochreous, the rest of their vestiture 
reddish-brown ; the under surface with oval and narrow ochreous scales, the vestiture of the legs similarly 
coloured, the posterior femora with a broad dark annulus beyond the middle. yes very large, narrowly 
separated. Rostrum carinate and rugulosely punctate at the base. Joint 2 of the funiculus elongate, 
about as long as 3-6 united, 3 and 4 equal in length, 5-7 short. Prothorax broader than long, narrowing 
from near the base, feebly constricted in front; densely, rugulosely punctate, and obsoletely carinate. 
Elytra much wider than the prothorax, moderately long, gradually narrowing from near the base, the 
sutural region depressed ; punctate-striate, the interstices rugulose and (except near the suture) convex. 
Meso- and metasternum hollowed between the middle coxe, the mesosternal depression limited in front 
by an arcuate ridge, the other depression foveiform. Legs moderately long; femora each with a sharp 
triangular tooth and a minute tooth exterior to it, the posterior pair carinate externally and reaching to 
a little beyond the apex of the abdomen ; intermediate and posterior knees each with a sharp spine. 
Length 63, breadth 34, millim. 
| Hab. Guatemaua, Senahu in Vera Paz (Champion). 
One specimen. Near #. sulphureus, but larger and longer, the prothorax less trans- 
verse and with a sharply-defined oblique vitta on each side, the elytra with numerous 
indefinite markings and a quadrate sutural patch, their outer interstices convex, the 
metasternal depression foveiform *, 
5. Hoplocopturus sulphureus, sp. n. (Tab. IV. fig. 7.) 
Subelliptic, opaque, piceous, the antenna and rostrum rufescent ; the vestiture close and fine: the head with 
a line around the eyes, the prothorax with the sides broadly, and the elytra with a transverse mark on 
the suture beyond the middle, another at the sides beyond this, the suture itself at the apex, and some 
other faint scattered markings, sulphur-yellow, the rest of the upper surface brown, the under surface 
uniformly sulphur-yellow, the legs flavo-cinereous, the intermediate and posterior femora with an almost 
bare dark annulus tewards the apex. Eyes very large, subcontiguous. Rostrum carinate and rugulosely 
punctate at the base. Joint 2 of the funiculus very elongate, about as long as 3-6 united, 3 as long as 1, 
4 slightly longer than 3, 5-7 short. Prothorax short, narrowing from the base; densely, finely punctate 
* We have another allied form from Chontales, but as the head is now missing the species cannot be 
described. |
