108 Christmas Island. 



The following species was obtained by Mr. Lister, and is 

 represented only by a single female : — 



56. Sessinia listen, Arrow, sp.n. 



Plavo-testacea, nitida, sericea, sat grosse punctata ; palpis 

 maxillaribus gracilibus latere apicali articuli ultimi latere interiori 

 subequali, ut lato quani longi, paruni dense punctato, niargine 

 basali valde reflexo ; elytris nitidis, distincte punctatis, ecostatis, 

 l^arce sericeis. 



Long. 13 mm. 



This species closely resembles the typical species 8. livida^ Fab., 

 but the silky covering is less fine and dense, and the punctuation 

 •coarser. The pro thorax is shorter, and the terminal joint of the 

 maxillary palpus, which in S. livida is almost cylindrical, is 

 ■distinctly triangular.

EHYNCHOLOBUS, Gahan, gen. nov. 



Apterous ; corbels of posterior tibise open ; claws of tarsi connate 

 :at the base. Rostrum rather broad, strongly dilated at the apex 

 in the male, so as to have a very distinct lateral process on each 

 side just below, and in front of, the insertion of the antennae ; 

 gradually and slightly dilated towards the apex in the female, and 

 Avithout distinct lateral processes ; marked off from the head by 

 a slight transverse impression ; scrobes deep, extending to the eyes 

 and almost as wide as them behind, narrowed in front. Scape of 

 the antennae reaching to, or a little beyond, the anterior margin 

 of the prothorax ; funiculus of seven joints, the second joint 

 longer than the first and almost or quite equal to the third and 

 fourth united; club short, ovate, three-jointed. Prothorax broadest 

 in front of the middle, slightly narrowed towards the base, more 

 strongly towards the apex. Elytra somewhat oval in shape ; 

 broader and less convex above in the male ; very little or not at all 

 broader than the prothorax at the base. Second sternite of the 

 4ibdomen almost as long as the post-coxal part of the first, and 

 marked off from it by a straight suture; much longer than the 

 third sternite, but not quite equal to the third and fourth taken 

 together. Femora stout, thick in the middle ; the hinder pair 

 flattened, or sometimes even slightly concave, on the posterior 

 (or inner) face ; hind tibiae obliquely truncate at the extremity.
