735. Hyperaxis quadraticollis, sp. n. 
Piceous ; closely covered with grey pubescence; antennas and 
legs dark fulvous. Head rugose-punctate ; anterior edge of clypeus 
nearly straight ; labrmn fulvous ; antennae not extending to middle 
of elytra, third and fourth joints equal, terminal live rather 
strongly triangularly widened, last joint ovately thickened. Thorax 
subcylindrical, 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. 
Bab. Andaman Islands {Coll. Brit. Mas.). 
The shape of the thorax and the rather long pubescence will 
help to discriminate this species. 
736. Hyperaxis duvivieri, Jac. (Trichotheca) Ann. Soc. Ent. Belg. 
xlviii, 1904, p. 086. 
Obscure dark fulvous, clothed with whitish scales ; antenuae 
and legs pale fulvous. 
Oblong, narrowly subcylindrical. Head entirely covered with 
scales ; labrum and palpi flavous ; antennae slender and filiform, 
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. 
Length 3 mm.

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 fulvollirsuta, Jac. (Demotina) Ann. Soc. Ent. Bela. 
xlviii, 1904, p. 364. 
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,
