178 CHRYSOMELID.E. 



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. 



Hob. India : Madura (Coll. H. E. Andrewes). 



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 antenna* 

 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 puuctate- 

 striate, the punctures nearly obsolete near apex, rows very dis- 

 tantly placed, interstices entirely impunctate. 



Length 2| mm. 



Hob. Nilgiris (Colls. H. E. Andrewes fy Jacoby). 



Differs from D. madurensis in the distinct elytral punctures and 

 the impunctate interstices. 



305. Dioryctus robustus, Jac. (Atropidius) Ann. Soc. Ent. Eely. 

 xlviii, 1904, p. 383. 



Fulvous ; 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 : antenna? pale 

 fulvous, terminal six joints widened but longer 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. 



Hob. Nilgiris. 



The largest of the known Indian species, has variable elytral 

 markings, the Jatter 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.
