735. Hyperaxis quadraticollis, sp. n. 



Piceous ; closely covered with grey pubescence ; antennae and 

 legs dark fulvous. Head rugose-punctate ; anterior edge of clypeus 

 nearly straight ; labrum fulvous ; antennae not extending to middle 

 of elytra, third and fourth joints equal, terminal five rather 

 strongly triangularly widened, last joint ovately thickened. Thorax 

 subcylindrieal, not broader than long, sides not widened, surface 

 closely covered with rather long yellowish hairs, middle with a 

 narrow impressed line. Elytra closely punctured and like the 

 thorax pubescent. Anterior and posterior only slightly thicker than 

 the intermediate femora; tibiae of latter not perceptibly emarginate 

 at apex ; all the femora with a small tooth. 



Length 4 mm. 



Hob. Andaman Islands (Coll. Brit. Mm.). 



The shape of the thorax and the rather long pubescence will 

 help to discriminate this species.

xlviii, 1904, p. 386. 



Obscure dark fulvous, clothed with whitish scales ; antennas 

 and legs pale fulvous. 



Oblong, narrowly subcylindrical. Head entirely covered with 

 scales ; labrum and palpi flavous ; antennae slender and tiliform, 

 extending beyond the middle of the elytra, intermediate joints 

 elongate, terminal joints shorter but not thicker. Thorax scarcely 

 broader than long, sides feebly rounded and but little widened at 

 the middle, surface finely rugose-punctate and pubescent. Scu- 

 tellum clothed with similar hairs or scales. Elytra obscure dark 

 fulvous, more strongly rugose than the thorax and punctured in 

 very closely approximate rows, also clothed with pale grey scales 

 and single erect black hairs. Legs pale ; femora only moderately 

 thickened, the intermediate femora less so than the others, all 

 armed with a small tooth. 



Lenyth 3 mm. 



Hab. Southern India : IVilgiri and Anaimalai Hills. 



A small species which certainly is better placed in the present 

 genus than in Trichotheca ; the scarcely widened sides of the 

 thorax and uniformly coloured upper surface will assist in its 

 recognition. 



737. Hyperaxis fulvohirsuta, Jac. (Demotina) Ann. Soc. Ent. Selg. 



xiv]ii, 1904, p. 384. 



Piceous, clothed with short pale fulvous pubescence ; elytra 

 with a smooth spot at base, a transverse band behind the middle 

 and a shorter band near the apex, black. 



Head entirely clothed with pale fulvous scale-like pubescence ; 

 anterior portion of clypeus and the labrum fulvous ; palpi slender, 

 fulvous ; antennae very slender, three or four basal joints pale 

 fulvous, other joints darker, third to seventh joints elongate, equal,
