202 CHKYSOMELID,*:. 



elongate first joints ; last abdominal segment with deep central 

 excavation. 



Length 3-4| mm. 



Hub. Burma: Euby Mines (Doherty Coll. Brit. Mus.). 



Not unlike C. unifasciatus, Jac., but with yellow frontal patch 

 on head, the base of elytra black, the posterior band of different 

 shape ; the male is much smaller and the antennae are much longer, 

 the anterior femora are more or less flavous. 



352. Cryptocephalus dilaticornis, sp. n. 



Black ; basal joints of antenna fulvous beneath ; elytra flavous, 

 the margins, a humeral spot and a transverse band behind the 

 middle, black ; abdomen flavous. 



d . Head deeply excavate between eyes, vertex swollen ; clypeus 

 strongly raised anteriorly and formed into a ridge ; labrum and 

 palpi flavous; antenna long, intermediate joints elongately 

 widened. Thorax strongly narrowed anteriorly, very convex, 

 with a narrow transverse sulcus behind front margin and a short 

 oblique depression on each side near scutellum, surface impunctate. 

 Scutellum subquadrate, apex rather rounded, base with fovea. 

 Elytra feebly lobed at sides, finely punctate-striate, the punctures 

 piceous, sutural and apical margins narrowly, basal margin more 

 broadly black ; epipleura? black only at their inner edges ; posterior 

 band broad with irregular margins, that extend upwards along 

 suture to middle. Pygidium and abdomen flavous. Prosternum 

 strongly produced in front, broader than long, posterior margin 

 concave ; tarsi short and broad. 



Length 4 mm. 



Hob. Assam : Patkai Mts. (Coll. Brit. Mus.}. 



A species remarkable in more respects than one ; the excavate 

 head and highly raised clypeus are not found in any other species so 

 far as I know, and although one of the antennae has eleven joints 

 (the other has the terminal two broken off) there is evidently 

 another joint wanting, since the eleventh is abruptly truncate at 

 apex. Described from a single specimen obtained by Doherty. 



Elytra otherwise marked. 



353. Cryptocephalus fiavocinctus, Jac. Ann. Mus. Civ. Genova,xxxu, 

 1892, p. 892. 



Black ; anterior and lateral margins of thorax flavous ; elytra 

 with a broad transverse band at middle and a spot at apex 

 flavous. 



Broad and robust. Head very flat, finely punctured and sparingly 

 pubescent ; space in front of eyes below their emargination and 

 labrum flavous ; antenn black, extending below middle of elytra, 

 basal joint flavous beneath, third and fourth equal, rest triangularly
