HYPOPLAGIUS. 
Hypoplagius, Desbrochers, Ann. Soc. Ent. Belg. xxxv. p. 40, nota (1891) ; Heller, Abhandl. Mus. 
Dresd. no. 11, pp. 3, 18. 
The characters of this genus, described from an old mutilated specimen from 
Cayenne, may be given thus :-— 
Rostrum moderately stout, short, not longer than the head as seen in profile, depressed and slightly widened. 
at the base, almost straight, the antenne inserted behind the middle, joints 1 and 2 of the funiculus 
equal in length, 3 much shorter, not longer than 4, 6 and 7 transverse, the club small, acuminate-ovate, 
its first joint shorter than the others united; eyes large, oval, somewhat angular below, separated in 
front by fully half the width of the base of the rostrum, the intraocular space equal in width above and 
beneath ; prothorax transverse, truncate in front, without ocular lobes; scutellum subtriangular, small ; 
elytra oblong, obtuse at the apex; pygidium very short, covered by the elytra ; mesosternum flat, declivous, 
the meso-metasternal suture straight and in a line with the middle of the widely-separated intermediate 
coxe ; metasternum long; ventral segments gradually ascending, the sutures almost straight, the second 
segment longer than 3 and 4 united; legs short, the posterior femora not reaching the apex of the 
abdomen, all the femora sublinear and unarmed. 
Hypoplagius includes a single species, peculiar to Eastern Mexico, Guiana, and 
Brazil, so far as at present known. It is very like a small, short-legged Zygops, but 
the pygidium is short and hidden, the rostrum and antenne are differently formed, the 
femora are unarmed, &c. 
1. Hypoplagius pectoralis. (Tab. IT. fieg. 27, 27a, b, 3.) 
Hy, oplagius pectoralis, Desbr. Aun. Soc. Ent. Belg. xxxv. p. 40°. 
Oblong, flattened above, convex beneath, opaque, nigro- or rufo-piceous, the legs reddish, the antenne 
ferruginous ; thickly clothed above and beneath with minute, hair-like, yellowish-cinereous or fulvous 
scales, the meso- and metasternum with coarser fulyous scales. Head rugulosely punctate, slightly 
depressed between the eyes; rostrum finely carinate, rugulosely punctate in the ¢, more sparsely 
punctate and shining at the tip in the 2. Prothorax constricted and narrowed in front, and also a little 
narrowed behind, bisinuate at the base; densely, rugulosely punctate, not or faintly carinate. Elytra 
oblong, a little wider than the prothorax; shallowly striate, the interstices almost flat and densely 
rugulose. 
Length 5-63, breadth 2-22 millim. (¢ 2.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé).—Soutnw America, Cayenne, Para. 
Three immature specimens, agreeing with the type communicated by M. Severin, of 
the Brussels Museum, and with others from Cayenne and Para in the British Museum. 
No locality was given by Desbrochers !. 
HELLERIELLA, gen. nov. 
Rostrum about as long as the head and prothorax, feebly curved, cylindrical and rather slender, much widened 
towards the base, sulcate along the sides beneath, the antennee inserted at about the basal fourth, joints 
1 and 2 of the funiculus long, subequal in length, 3 and 4 much shorter, the club ovate, small, its basal 
joint as long as the others united ; eyes large, separated by more than half their width as seen from 
above, sinuato-acuminate below ; prothorax cylindrical, long, truncate at the apex, feebly sinuate at 
the base, the ocular lobes almost obsolete; scutellum very small, convex; elytra comparatively short, 
oblong-cordate ; pygidium not visible ; intermediate coxe narrowly separated ; mesosternum flattened ; 
metasternum short ; ventral segments gradually ascending, 1 very long, 2 three times as long as 3 or 4;
