HOPLOCOPTURUS, 53 
HOPLOCOPTURUS. 
Hoplocopturus, Heller, Abhandl. Mus, Dresden, no. 11, pp. 4, 50, tab. fig. 4 (1895). 
Under this genus, the type of which is Copturus armatus, Boh., are placed various 
species agreeing in the following characters * :— 
Mesosternum (as in Mremynurus) flattened, declivous, with a shallow transverse depression limited anteriorly 
by an arcuate ridge (reduced to two short carine in H. costatipennis). Metasternum flattened 
(H. leptopus, &c.), hollowed, or foveate between the middle coxe (H. elegans). Rostrum not reaching 
beyond the middle of the metasternum. Joint 2 of the funiculus elongate. Posterior femora extending 
beyond the apex of the abdomen (shorter in H. elegans and H. densus), carinate or not externally, the 
inner apical lamella spiniform or acutely produced. 
Hoplocopturus is connected with Mnemynurus by intermediate forms, and it can only 
be separated therefrom by the shorter rostrum. The arcuate ridge on the mesosternum 
distinguishes it from Copturus. The Central-American forms may be grouped thus :— 
a, Rostrum reaching the middle of the metasternum ; femora unidentate . . . Species 1, 2. 
6. Rostrum not (except in H. leptopus, 2) reaching the middle of the 
metasternum. 
a’. Femora bidentate; metasternum hollowed between the middle coxe . . Species 3-6. 
é'. Femora unidentate. 
a’, Head rather broad, with very large eyes: body oblong-rhomboidal or 
elliptic. 
a*, Metasternum hollowed between the middle coxe. 
a‘, Elytra costate ; the arcuate mesosternal carina reduced to two short 
ridges . 1 1 ee ee ee ee ee ee ee ee + Species 7. 
b*. Elytra not costate ; the arcuate mesosternal carina complete. . . Species 8, 9. 
b°. Metasternum foveate between the middle coxe: species very small . Species 10-18. 
8°. Head smaller, the eyes not so large ; metasternum hollowed or flattened 
between the middle cox: body subrhomboidal . . . . . . . . Species 14, 15. 
1. Hoplocopturus javeti, sp. n. (Tab. IV. figg. 3, 3a.) 
Copturus javeti, Jekel, in litt. 
Oblong-rhomboidal, shining, piceous or rufo-piceous, the prothorax sometimes rufous, the antenne ferruginous 5 
the vestiture sparse, fine on the elytra, coarser on the prothorax, ochreous or yellowish-white, condensed 
into a line around the eyes, a line along the anterior margin of the prothorax, and a sinuous fascia 
towards its base, the latter extending down the median lobe, the elytra with various interrupted denser 
yellowish lines on the basal half and a narrow whitish sutural stripe; the under surface, a broad bare 
space along the middle of the abdomen excepted, thickly clothed with coarse, oval, whitish scales, the 
vestiture of the legs also white. Eyes very large, narrowly separated. Rostrum reaching to about 
the middle of the metasternum, rugulose and sharply carinate at the base. Joint 2 of the funiculus 
elongate, rather longer than 8 and 4 united, the latter subequal in length, each as long as 1, 5-7 short. 
Prothorax somewhat convex, subconical, a little broader than long, with rounded ocular lobes; closely, 
coarsely punctate, the punctures transverse and here and there confluent, a narrow space at the 
base densely, finely punctate, the disc subcarinate. Scutellum small, tuberculiform. Llytra rapidly 
* Copturus furfuraceus (Germ.) is included in Hoplocopturus by Heller, but it wants the transverse 
depression at the base of the mesosternum.
