Genus HETEROPHTHALMUS. 



Heterophthalmus, Blanch., Cat, Coll. Ent. Mus. Paris, 1851 (1850), 

 p. 234; Ohaus, Deutsche Ent. Zeits. 1912, p. 280. 



TYPE, Heterophthalmus ocularis, Bl. 



Range. South India. 



Body small, differing greatly in shape in the two sexes, with a 

 very scanty and inconspicuous clothing of minute hairs above and 

 beneath. 



The organs of the mouth are much reduced. The labrum is 

 only slightly visible externally, scarcely vertical, with a very 

 minute but acute process in the middle. The mandibles are 

 small, not highly chitinised, not meeting or co-adapted, bluntly 

 rounded at the extremity and with a feeble molar surface. The 

 maxilla is acuminate, but not toothed. The labiuin forms a small 

 rounded lobe. The clypeus is narrow, rather long relatively and 

 strongly reflexed at the front margin. The front tibia is armed 

 with three blunt teeth, and the longer claw on the front and 

 middle feet is very minutely cleft ; there are two spurs to the 

 hind tibia in both sexes (not one only in the 6 , as presumed by 

 Dr. Ohaus). 



c? . The body is rather narrow and parallel-sided. The eyes 

 are very large and prominent, and the clypeus correspondingly 

 reduced, the forehead being only a little wider than the diameter 

 of the eye. The antennae are 9-jointed and the club longer than 

 the foot-stalk. The legs are slender and the tarsi very long ; the 

 two claws of the front foot are very unequal. The pygidium is 

 convex. 



$ . The body is short and broad, and the elytra dilated to 

 behind the middle. The eyes are rather small. The antennae 

 are 9-jointed and the club much shorter than the foot-stalk. 

 The legs are shorter than in the male, the tarsi very short ; the 

 hind femur and tibia are very short and thick. The pygidium is 

 rather flat. 



There is only one known species, taken- in 1836 by Perrottet, 

 and I believe never found again. 



309. Heterophthalmus ocularis. 



Heterophthalmus ocularis, Blanch.,* Cat. Coll. Ent. Mus. Paris. 

 1851 (1850), p. 234. 



Uniformly reddish testaceous, with minute sparse greyish hairs 

 above and beneath. 



The head and clypeus are coarsely and rather closely punctured, 

 the vertex less closely. The pronotum is strongly punctured, 

 with the sides strongly rounded and all the angles very obtuse. 

 The scutellum bears a few large punctures, and the elytra are 

 coarsely, closely and coufluently punctured, with three narrow, 

 rather prominent costae outlined by double rows of punctures. 

 The pygidium ia rather finely, but not very closely, punctured.
