this spine there is a short tooth, and also another a Httle helow the 

 knee which is not dentate on either side ; the hind tibiae are very 

 much cui-ved, have a sliarp inner tooth below the knee, are strongly 

 mucronate at apex, and have a distinct apical spur ; the inner hind 

 claw is half the size of the outer and both are cleft. 



This species is easily recognised by the great development of the 

 hind femora, the horizontal spine of which reaches underneath as far 

 as the knee ; in the small development the trochanters are not as 

 much fused with the thigh as in the large examples. 



Female unknown. 



Length 5-6|- mm. ; width 3-3^ mm.

Male : Head, pi-othorax and pectus fuscous ; antennas, legs, and 

 elytra rufescent, the latter is covered with contiguous yellow scales 

 but the whole of the pygidium has a black, velvety coating ; clypeus 

 with the two median teeth very little distinct ; prothorax covered 

 with a very short, dense pubescence, partly appressed, and some 

 slightly elongate yellow scales ; scutellum scaly ; elytra slightly bi- 

 costate on each side, the two costse unite at the apex in a distinct 

 callus, and are very briefly setigerous, the whole surface is covered 

 with small, contiguous scales ; edge of the propygidium and sides of 

 abdomen covered with yellow scales a little paler than those on the 

 upper surface ; trochanters of hind legs very long and sharp, hind 

 thighs with a well-developed tooth close to the inner part of the 

 knee which is not dentate outwardly, hind tibiae moderately curved, 

 grooved beneath, with a very small tooth on each side of the basal 

 part of the groove and with both edges distinctly serrate, mucro 

 curved, sharp but short, no apical spur ; inner claw of hind legs not 

 half the length of the outer, and not cleft.
