IRESIOIDES. 319 



392. Nida andamanica, sp. n. 



Very like N.jiavovittata, Pasc, but differs from it by the absence 

 ot: the testaceous band along each elytron, and in the C-shaped 

 white baud at each side of the prothorax which is less distinctly 

 marked ; the anterior part of this band widened out and greyish, 

 rather tban white, in colour. The testaceous band of N. jlavo- 

 vittata rejilaced by faint grey bands, formed of pubescence the 

 hairs of which lie somewhat transversely ; the underlying derm, 

 however, is as a rule quite black, although a small testaceous spot 

 is in some specimens visible near the base. 



Length 11-14 ; breadth 2-2| mm. 



Hab. Andaman Islands. 



As this form agrees structurally with N.jlavovittata, it ought, 

 perhaps, to be regarded as a race or local variety of that species, 

 sufficiently different in colour to be entitled to a distinctive 

 name. 



Group GLAUCYTINI. 



Head short, slightly concave or sometimes nearly fiat between 

 the antennae ; front vertical, somewhat narrowed between the 

 eyes, especially in the male ; eyes large, prominent, finely facetted, 

 deeply emarginate ; antenual supports emarginate in front. An- 

 tennte longer as a rule than the body in both sexes. Prothorax 

 subcylindrical, unarmed at the sides. Front coxae globular, their 

 acetabula rounded on the outer side, closed or very nearly closed 

 posteriorly. Acetabula of middle coxae not open to the epimera. 

 Legs variable in length ; the femora more or less distinctly 

 thickened towards the apex ; the hind tarsi not long, the first joint 

 very little (sometimes not) longer than the second and third 

 united. Vein Cu 1 of wings simple; Cu 2 absent.
