hairs also lonning rows, unlike the irregular punctures and hairs 

 of the intervals. Pygidiuiu rather long, vertical, with slightly 

 truncated apex, everywhere closely punctured and clothed with 

 long hair, only the part before the extremity shining and almost 

 bare. Ventral segments sparingly, breast more sti'ongly, hairy. 

 Legs moderately strong, sparingly clothed with long hair ; front 

 tibiae with three long teeth, the spur at the inner edge long, bent 

 downwards and outwards ; middle and hind tibicS slightly swollen 

 externally, scarcely constricted before the end ; tarsi rather long 

 and strong, with the claws very unequal in length, the inner hind 

 one wantnig or reduced to a hardly visible rudiment. Antennae 

 10-jointed, with the club hardly as long as the foot-stalk, ex- 

 cluding the basal joint. Mouth-parts small, but well developed. 

 Labrum rather shorter than the anterior face of the clypeus, 

 mandibles and labium as in the preceding species, the chisel-shaped 

 tooth of the maxilla still larger but the sharp ventral tooth 

 adjoining it a Httle smaller : on the dorsal side also a small, sharp 

 free tooth. 



The species resembles at first sight HeteropJithalmm ocularis, BL, 

 from Pondichery, but is smaller, and easily distinguished by the 

 form of the labrum, which in Blauchard's species bears a tooth- 

 like middle process.
