CHRYSOMELIDjE. 
lobes acutely produced, angulate; surface with a few punctures at 
base indicating rows, almost impunctate posteriorly, a slightly more 
distinct row of fine punctures near lateral margins ; interstices 
sparingly punctured. Legs short and robust, tarsi obscurely 
piceous. 
Length 2 mm. 
Hub. India : Madura (Cull. II. E. Andr ewes'). 
A very small and strongly convex species, looking much like a 
Lamprosoma but without visible scutellum and with strongly pro- 
duced lateral elytral lobes. 
304. Dioryctus glabricollis, sp. n. 
Dark blue above, black beneath ; basal joints of antennae 
fulvous. 
Head extremely finely and sparingly punctured, dark blue ; 
antennae extending to base of thorax, basal four joints dark 
fulvous, rest black, third and fourth very small. Thorax strongly 
transverse, widened at middle, basal margin deeply sinuate at 
sides, medial lobe acutely produced, surface entirely impunctate. 
Elytra broadly rounded at apex, very finely but distinctly punctate- 
striate, the punctures nearly obsolete near apex, rows very dis- 
tantly placed, interstices entirely impunctate. 
Length 2| mm. 
Hob. Nilgiris (Colls. H. E. Andrewes Sf Jacoby). 
Differs from D. madurensis in the distinct elytral punctures and 
the impunctate interstices. 
305. Dioryctus robustus, Jew. (Atropidins) Ann. Soc. Ent. Bely „ 
xlviii, 1904, p. 383. 
Eulvous ; elytra with a transverse bilobed black band at base and 
one large black spot or four spots (2 . 2) near apex. 
Broad, subquadrate, highly convex. Head very finely and closely 
punctured ; eyes broadly emarginate ; labrum pale : antennae pale 
fulvous, terminal six joints widened but louger than broad. 
Thorax transverse, strongly widened at middle and narrowed in 
front, basal lobe strongly and acutely pointed, surface impunctate. 
Elytra finely punctate-striate, shoulders rounded, interstices flat 
and finely punctate, the outer two strongly convex at apex. Pro- 
sternum subquadrate, with the usual three ridges. 
Length 4.| mm. 
Hub. Nilgiris. 
The largest of the known Indian species, has variable elytral 
markings, the latter probably disappear entirely in some speci- 
mens. In the spotted form one spot is placed on the shoulders, 
another near scutellum between second and fifth row of punctures, 
the other two behind the middle close together between the basal 
spots.
