by three specimens from Chiriqui and one from Vera Paz. Smaller and narrower than 
I’. spinole, the rostrum more curved, the elytra with short fuscous and cinereous 
lines on the disc, the dark lines forming an interrupted median fascia and a short 
scutellar streak, the alternate interstices without sete. In one immature specimen 
from Bugaba the rostrum is quite smooth (except at the base) and the prothoracic 
carina is wanting. 
SUPPLEMENT. 
Durinea the course of publication of the preceding pages various interesting forms 
have been received from Costa Rica, mainly from Prof. G. Biolley and Mr. C. F. 
Underwood, of San José. These are now enumerated, together with a few other 
species kept back for further study or previously overlooked. 
HYLOBIINA. 
HILIPUS (pp. 7-49). 
Amongst the four new species now added, one, H. terebrans, is a peculiar 
form approaching Cholus*. The synoptic table (antea, p. 8) requires modifying 
to include it :— 
A. Anterior coxe contiguous . . 6. ee ee eee ee ee Species 1-78. 
B. Anterior coxe narrowly separated . 2. 1. ee ee ee eee) «Species 79. 
14(s). Hilipus rufocinctus, sp.n. (Tab. XXXV. figg. 16, 16a, ¢.) 
Elongate, subcylindrical, shining, black, the prothorax (except at the base and apex), a broad annulus on the 
incrassate portion of the femora, and the metasternum (except at the sides), rufous; the elytra with 
various scattered whitish-ochreous spots, which are condensed into an irregular transverse fascia before 
the middle and another towards the apex; the ventral segments 1-5 each with a few small white scales 
on either side in front. Head almost smooth, slightly depressed between the eyes, which are well- 
separated; rostrum exceedingly stout, arcuate, finely, very sparsely punctate, the antenne inserted 
towards the apex. Prothorax as long as broad, subcylindrical, abruptly narrowed at the base and apex ; 
sparsely, finely punctate. Elytra elongate, very little wider than the prothorax ; finely seriate-punctate,
