CHRYSOMELIDJE. 
elongate first joints : last abdominal segment with deep central 
excavation. 
Length 3-4d mm. 
Hab. Burma: Euby Mines ( Doherty — Coll. Brit. Mus.). 
]N T ot 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. Cryptocephalns dilaticornis, sp. n. 
Black ; basal joints of antennae fulvous beneath ; elytra flavous, 
the margins, a humeral spot and a transverse baud behind the 
middle, black ; abdomen flavous. 
c S • Head deeply excavate between eyes, vertex swollen ; clypeus 
strongly raised anteriorly and formed into a ridge ; labrum and 
palpi flavous ; antennae 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 snbquadrate, 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 ; epipleurae black onty 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. 
Hab. 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. Cryptocephalns fiavocinctus, Jac. Ami. Mus. Civ. Genova, xxxii, 
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 ; antennae black, extending below middle of elytra, 
basal joint flavous beneath, third and fourth equal, rest triangularly
