HILIPUS. 49 
Fourteen specimens, one only being from Guatemala. This species, except that it 
is very much smaller, has the same general shape and coloration as H. angulosus, in 
which the apex of the first ventral segment is slightly produced in the centre behind. 
In the setigerous elytra it resembles H. asperatus, &c. 
The following species is unknown to me. It may belong to Hilipinus. 
78. Hilipus tugusti. 
Heilipus tugusti, Boh. in Schénh. Gen. Cure. vii. 2, p. 45°, 
Hab. Mexico (coll. Chevrolat'). 
I am unable to certainly identify this species amongst our material, and the type of 
it cannot be found in the Chevrolat collection at Stockholm. It is described as nigro- 
piceous in colour, variegated above with yellowish piliform scales, the elytra with a 
large, transverse, fulvous patch far beyond the middle. The prothorax broader than 
long, rounded at the sides, closely granulate throughout, and with rather prominent 
ocular lobes. The elytra one-half broader than, and nearly three times as long as, the 
prothorax, with the sides straight to beyond the middle, and then convergent to the 
apex, which is rounded; rather deeply and closely seriate-punctate, with the interstices 
narrow, subconvex, and transversely rugose. | 
In my remarks under J. belti (antea, p. 15) mention is made of a nearly allied form 
with a peculiarly shaped prothorax: a second specimen of this insect has since come 
to hand, and a description of it is therefore appended :— 
14 (a). Hilipus compressicollis, sp.n. (Tab. IV. fig. 8, ¢.) 
Oblong-ovate, shining, black, a broad space extending across the entire disc of the prothorax and the incrassate 
portion of the femora rufous; the elytra with numerous, irregular, whitish, transverse spots and markings, 
the latter tending to form two common angulated fascie, one before, the other beyond the middle. Head 
foveate between the eyes; rostrum stout, curved, about as long as the prothorax, sparsely punctate 
towards the base. Prothorax broader than long, rounded at the sides, sinuously narrowed behind and 
constricted and much narrowed in front, the disc broadly and obliquely depressed on each side before the 
middle (the depression extending inward from the lateral constriction), the base very strongly bisinuate, 
the surface sparsely, irregularly punctate. lytra one-half wider than the prothorax, subparallel towards 
the base, seriate-punctate, the interstices faintly transversely wrinkled. Venter with a broad depression 
extending down the middle of segments 1 and 2. 
Length 16-17, breadth 64-64 millim. (¢.) 
Hab. Nicaracva, Chontales (Janson); Costa Rica, Chirripo, Atlantic slope (Biolley). 
Two males, agreeing perfectly enter se. Distinguishable at a glance from H. belti 
by the shorter, broader, compressed prothorax, with rounded sides and more strongly
