HILIPUS. 47 
Prothorax broader than long, moderately rounded at the sides, considerably narrowed in front, bisinuate 
at the base, sparsely granulate. Elytra one-half wider than the prothorax, subparallel towards the base, 
conjointly rounded at the apex, the humeri rounded; seriate-punctate, the interstices transversely wrinkled 
and also granulate. Ventral segment 1 in the ¢ shallowly grooved down the middle, and with a dense 
oblong patch of ochreous and white scales on each side of the depression; in the Q sometimes 
depressed along the middle behind. Tibise mucronate in the 9, obsoletely so in the ¢, 
Length 94-12, breadth 33-5 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet, Bugaba (Champion). 
Eleven specimens. Not unlike H. pulverulentus, but narrower and less robust, the 
prothorax narrower, less rounded at the sides, and with the fulvous clothing more or 
less concentrated into two broad converging vittee on the disc; the elytra less sinuate 
at the base, and with a transverse black mark or fascia beyond the middle (sometimes 
reduced to a small spot), and usually a spot beyond it. 
75. Hilipus hyperoides, sp. n. 
Oblong-ovate, shining, black, the legs and antenne in part piceous or rufo-piceous; the upper surface some- 
what thickly clothed with fulvous scales, with some whitish ones intermixed, the latter concentrated into 
a small patch on the disc of each elytron beyond the middle and also covering the scutellum; the under 
surface and legs with scattercd, whitish, piliform scales. Head closely punctured, foveate between the 
eyes, which are widely separated; rostrum moderately stout, curved—in the g about as long as the 
prothorax and closely punctured throughout, in the Q a little longer, more slender, and smoother at 
the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the sides, 
abruptly constricted and narrowed in front, strongly bisinuate at the base ; closely granulate at the 
sides, sparsely and transversely so on the dise. Elytra one-half wider than, and three times as long as, 
the prothorax, sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, the 
humeri rounded and somewhat swollen; deeply seriate-punctate, the interstices broad, granulate on the 
apical declivity, the outer ones granulate and transversely rugose. Metasternum and ventral segments 
1-4 very sparsely, minutely punctate, the first segment unimpressed in both sexes, the metasternum 
short, foveolate along the outer margin. Legs comparatively short, the tibie feebly mucronate. 
Length 8, breadth 3? millim. (¢ 2.) 
Hab. Mexico, Santecomapan in Oaxaca (Sallé); British Honpuras (Blancaneauz). 
- Two rather worn specimens. ‘This species resembles H. dioculatus in general shape, 
except that it is smaller and less convex, and has relatively shorter elytra. The amount 
of white squamosity is variable, it being more abundant in the Mexican insect than in 
the one from Honduras. 
76. Hilipus sulcifer, sp. n. (Tab. IV. figg. 6, 6; 6a, terminal ventral 
segments, 9 .) 
Elongate-ovate, black or piceous, the antenne and legs sometimes partly rufescent; mottled above with a 
somewhat dense clothing of fulvous and whitish scales, the latter often aggregated so as to form an oblique 
stripe on the outer part of the elytra below the base and a common apical patch, the elytra with a spot 
on the outer part of the disc beyond the middle (in some specimens large and sharply defined, in others 
indistinct), an oblong one close to the suture at the apex, and sometimes several others on the apical half, 
black; the under surface and legs thickly clothed with whitish and fulvous scales. Head rugosely 
punctured and not or feebly foveate between the eyes, which are rather narrowly separated; rostrum 
in the ¢ stout, feebly curved, as long as or longer than the prothorax, rugosely punctured and obsoletely 
quadricarinate towards the base, smoother at the tip, that of the 2 a little longer and smoother, the
