234 RHYNCHOPHORA. 
very prominent and narrowly separated from the prothorax; joint 2 of the funiculus about twice as long 
as 1, the scape extending to about the posterior margin of the eyes. Prothorax transverse, rounded at 
the sides, a little narrowed in front, deeply bisinuate at the base; closely, finely punctate and obsoletely 
canaliculate. Elytra moderately long, considerably wider than the prothorax, broader in 9, flattened 
on the disc anteriorly, the base sinuate and obliquely truncate laterally, the humeri somewhat tumid ; 
rather coarsely punctate-striate, the interstices flat or feebly convex and closely punctulate. First 
ventral segment slightly hollowed down the middle in §. Anterior tibie sparsely denticulate, sharply 
unguiculate in ¢, the intermediate pair also with a small uncus in this sex. 
Length 83-104, breadth 2,%-4 millim. (¢ 9.) 
Hab. Costa Rica (Pittier, in Mus. Brit.), Surubres near San Mateo, 250 metres, 
Pacific slope (Biolley), Piedras Negras (U.S. Nat. Mus.). 
I have seen twelve specimens of this species; two of those in the British Museum, 
received in 1855, are labelled “ Guatemala,” but no reliance can be placed on this 
locality. The insect when fresh is thickly clothed with an ochreous or sulphur-yellow 
exudation, through which the markings are traceable. The short, broad head and the 
still more prominent eyes separate the southern JV. laticeps from its Mexican allies.

Hab. GUATEMALA ! 2, 
This insect is stated to be near N. cinerosus, Schonh., but to differ in its larger size, 
and in having the prothorax broader than long and bisinuate at the base, the elytra 
each extending forward at the base, &c. It is 11 mm. long, including the rostrum; 
uniformly clothed with cinereous scales, and also pubescent; the elytral inter- 
stices 4-7 gibbous towards the apex. This lJast-mentioned character differentiates 
NV. cinerascens from any of the species in our collection. 
GERMARIELLA, gen. nov. 
Rostrum broad, flattened, subquadrate, the upper portion widened towards the base, sulcate, emarginate at 
the apex, the bare nasal plate extremely short, the scrobes deep, sinuous, extending to beneath the eyes, 
the latter rounded, convex, and strictly lateral; antenne slender, the scape feebly clavate and about 
reaching the posterior margin of the eye, Joint 2 of the funiculus much longer than 1. 3-7 obconic; 
prothorax short, rounded at the sides, broadly margined (as seen from behind) and strongly bisinuate at 
the base; scutellum small, depressed; elytra very broad, comparatively short, sinuate at the base, 
conjointly rounded at the apex, 10-striate, the outer strie approximate from the basal third; legs 
slender, comparatively short ; anterior tibiz feebly denticulate and unguiculate ; posterior tibiee narrowly 
laminate and squamose at the apex, the glabrous articular surface cavernous and ascending; tarsal 
claws free; body oblong, winged, uniformly squamose, in life clothed with a powdery exudation. 
Type, Curculio juvencus, Oliv. (= diadema, F.). 
Curculio juvencus, Oliv., and the very closely allied Cyphus pudens, Boh., seem to 
me to be best separated from Cyphus, from which they differ in several details of 
structure, as well as in general facies. ‘The basal margin of the prothorax is as deeply 
hollowed for the reception of the separately rounded anterior edge of each elytron as
