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 subrotuudate, 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 Schcenherr (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 Cu?-culionida, 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 Schcenherr's 

 description, this in external colour seems to resemble his Pote- 

 riophorus niveus, iv. 846. 



The figure, 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. 



^HE following is a very imperfect list of the Insects collected 

 ly me during a residence of about a year and a half in Jamaica : 

 iperfect, because many species seem to be as yet unnamed, 

 id also because many others which I omitted to register with 

 number, it would now be exceedingly difficult to determine, 

 [mperfect as it is, however, I communicate it, as local lists are 

 Iways 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.
