Mr. P. H. Gosse on the Insects of Jamaica. 
a slightly impressed line down the middle, which runs into a 
triangular depression in front of the scutellum ; scutellum white, 
without apparent punctures. 
Elytra, each furnished with nine deeply impressed lines, the 
third (from the suture) joined at the tip with the eighth, fourth 
and seventh joined at the tip, and the third and fourth also joined 
at the tip and connected with the fourth by a branch. 
Hab. Philippine Islands. Mus. Brit. 
Elytra considerably depressed above, the base somewhat mar- 
gined close to the thorax; each elytron with the lateral edge 
widely sinuated, the end rounded. 
Legs strong, the anterior pair close together at the base ; tibise 
short, slightly bisinuated within ; tarsi with the two basal joints 
narrow, the second subquadrate and both grooved at the base, 
the third subrotundate, somewhat widest in front, grooved at the 
base, and furnished on the sole with very close thick-set hairs. 
This subgenus would almost appear to connect the two sub- 
divisions Cryptopygi and Gymnopygi of the family Calandridce 
of Schoenherr (Genera et Species Curculionidum, viii. p. 334) ; 
with the former it nearly agrees in the position of the antennse, 
being about the middle of the beak (which however, as in Bren- 
tida and many Cw'culionidce, may be only a sexual distinction) ; 
with the latter in the pygidium being exposed, or not covered by 
the elytra. The form may thus prove interesting as one of those 
links which serve to show how families, subdivisions and genera 
lapse into each other. In appearance, judging by Schoenherr^s 
description, this in external colour seems to resemble his Pote- 
riophorus niveus, iv. 846. 
The figm^e, carefully made, of the natural size, by Mr. Wm. 
Wing, will show its form, the profile, and also the markings of 
the only species which was found by Mr. Cuming, F.L.S., at the 
north end of Luzon in the Philippine Islands in the province of 
Cagayan. 
XII. — On the Insects of Jamaica. By Philip Henry Gosse. 
The following is a very imperfect list of the Insects collected 
by me during a residence of about a year and a half in Jamaica : 
imperfect, because many species seem to be as yet unnamed, 
and also because many others which I omitted to register with 
a number, it would now be exceedingly difficult to determine. 
Imperfect as it is, however, I communicate it, as local lists are 
always useful to science : and I shall use this one as a vehicle 
for recording a few scattered notices of individual species, which, 
though too trivial to form separate papers, may yet, as isolated 
facts, be worth preserving from oblivion.
