NEW SPECIES OF INDIAN PHYTOPHAGA 125 



NISOTRA CARDONl n. sp. 



Testaceous, the terminal joints of the antennae and the breast 

 and abdomen black, thorax nearly impunctate, longitudinally 

 grooved at the sides, elytra finely geminate punctate-striale, last 

 abdominal segment fulvous at the apex. 



Length 4 mill. 



Head impunctate, clypeus separated by oblique grooves from the 

 face, broad, impunctate, apex of mandibles black, antennae robust, 

 black, the lower four joints testaceous, the third joint more slender 

 and slightly longer than the fourth one, thorax more than twice as 

 broad as long, the sides straight at the base, slightly rounded at the 

 middle, the anterior angles thickened, the disc microscopically 

 punctured, the anterior margin with a longitudinal groove at the 

 sides nearly joined to another at the base; elytra convex, not much 

 pointed at the apex, testaceous, shining, finely punctured in closely 

 approached double rows, the last interstices at the sides slightly 

 convex, below black, the last abdominal segment fulvous at the 

 apex, legs robust, testaceous or fulvous, prosternum elongate, with 

 a lateral ridge. 



Hab. : Mandar, Bengal (Cardon). 



The elytra in this species are not nearly so pointed as in the 

 Ceylon species N. hadia Har. and have a very slight aeneous lustre 

 in some specimens, the thoracic groove is nearly contiguous which 

 will help to distinguish the species. 



MIGRAPHTHONA n. gen. 



Body oblong, antennae filiform, the second joint short, the third 

 twice as long, the following joints more elongate, thorax strongly 

 transverse, of equal width, the angles not produced, the surface 

 without sulcus, elytra irregularly punctured, their epipleurae 

 narrow at the middle but distinct, posterior femora moderately 

 robust, the tibiae not sulcate, all armed with a small spine, the 

 metatarsus of the posterior legs as long as the following joints 

 together, claws appendiculate, prosternum very narrow, nearly 

 indistinct, the anterior coxal cavities closel. 



The small species for which this genus is proposed resembles 

 Luperomorphus in its general aspect but differs in the structure of 

 the antennae in regard to the second and third joint and in the 

 closed coxal cavities ; the elytral epipleurae are narrow below the 

 middle and the anterior coxae are closely approached, so that the 

 prosternum is extremely narrow; the posterior femora are however 

 strongly enough incrassate to place the insect in the Halticince.
