RHINOSPATHE,—EXOPHTHALMUS. 249 
Hab. Costa Rica? (Wagner ', Sallé, Van Patten, Mus. Brit.), San José, Guaitil de 
Pirris (Biolley), Escazu, Pozo Azul (Underwood), Irazu (Rogers), Piedras Negras 
(U.S. Nat. Mus.) ; Panama, Chiriqui (Zrétsch, ex Staudinger). 
A common insect in Costa Rica; the variety is represented by five specimens (¢ @ ) 
from Chiriqui. The squamose portions of the surface are usually more or less coated 
with a powdery ochreous exudation, this being particularly noticeable on the excavate 
scutellar patch. Chevrolat’s reference! to Hypsonotus albomarginatus, Motsch. (Etudes 
Ent. v. p. 22), is incorrect. 
2. Rhinospathe v-album, sp. n. (Tab. XI. figg. 2, 2a, 2.) 
©. Elongate, robust, subfusiform, shining, black or piceous; almost glabrous above, except on the apical 
declivity of the elytra, which is clothed with black or blackish-brown scales intermixed with semierect 
black and white seta, the dark scales preceded by a common, v-shaped, irregular fascia of white scales, 
the lower margin of the elytra and the sides of the body beneath also more or less albo-squamose, the 
rest of the under surface with a few widely scattered adpressed hairs, the tibie and antenne setose. 
Head and rostrum closely punctate; the rostrum longer than broad, widened outwards, obsoletely 
carinate down the middle, and with a fine oblique carina on each side extending from the transverse 
inter-antennal ridge to near the small inter-ocular fovea, the declivous apical portion hollowed, the sides 
deeply foveate before the eyes, the latter large, rounded, and moderately prominent; antennal scape 
widened from near the base. Prothorax about as long as broad, subeylindrical, gradually narrowing 
from the middle forwards ; transversely wrinkled and very sparsely punctate, depressed and longitudinally 
suleate in the middle at the base. Scutellum transverse, small. Elytra widened to the middle, 
conically produced at the apex, excavate along the suture at the base; seriate-punctate, the interstices 
flat or transversely wrinkled. Tibize denticulate within, the anterior pair feebly unguiculate. 
Length 14-20, breadth 42-68 millim. 
Hab, Guatemata (ea Donckier), Zapote (Champion), Escuintla (Conradt). 
Four specimens. This species differs from FR. albomarginata in having the rostrum 
less excavate behind the transverse inter-antennal ridge, and the declivous apical 
portion less dilated ; the elytra neither depressed along the suture nor densely villose 
at the apex, the basal excavation small and almost bare, the squamose apical portion 
of their surface preceded by a common v-shaped fascia of white scales.

The numerous species referred to this Tropical-American genus agree with the type 
(Curculio quadrivittatus, Oliv.) in having two or more abbreviated supplementary rows 
of punctures on the exterior portion of the disc of the elytra; the outer striz entire ; 
the gene emarginate in front; the scrobes lateral, long, and descending; the eyes 
large, more or less prominent, not strictly lateral; the vibrisse wanting; the scutellum 
well developed; the femora unarmed; the tibiz with or without denticles, the anterior
