of the horus of the second genital segment, more or less fuscous brown. Front femora 

 with a long streak on the under side, the trochanters at their apex, a spot at the base of 

 the middle femora, as well as sometimes the disk posteriorly of the mesosternum, 

 brownish ochreous. 



Antennce (PI. II. fig. 1, a.) slender, about three-fourths the length of the body; first 

 joint shorter (about one-sixth) than the other three together ; second less than half the 

 length of the first ; third about two-thirds the length of the second ; fourth slightly 

 shorter than the second, stouter, attenuate from the middle upwards. 



Pronotum with an impressed longitudinal central line. Mcsoiwtum slightly and 

 gradually widening to al)out the middle, disk rather flat, with a fine impressed longitu- 

 dinal percurrent central line. 



Front legs : femora not very stout, thickened about the middle; til)ia about four- 

 fifths the length of the femur ; tarsus (PL II. fig. l,f.t.), about half as long as the tibia, 

 first joint nearly two-thirds the length of the second, second cleft before the middle. 



Middle legs : trochanter armed with spines ; femur with scattered spines all round, 

 shorter than the tibia and tarsus taken together ; tibia about four-fifths the length of the 

 femur, with a series of spines on the inner side ; tarsus (PI. II. fig. \,m.t.) about two-thirds 

 the length of the tibia, first joint three times the length of the second. 



Hind legs : femur about two-fifths longer than tibia and tarsus together. 



Ahdomen : sixth ventral rather longer than any of the preceding segments, hind 

 margin straight, with a narrow transverse depression. 



Genital segments : first below, about as long as any three ventral segments, except 

 the sixth, hind margin straight, sides obli(|ue ; second with horns reaching nearly to apex 

 fif third below ; third (PI. II. fig. l,g.) above with the lateral angles rounded. 



Closely resembling Ilalobates Jiaijantis, but differs, inter alia, liy tJie greater length 

 of the first joint of front tarsus, more spiny middle femora, more strongly impressed line 

 on the thorax, &e. 1 have seen the male only.
