the others ; principal suture straight, a little in front of the 

 middle ; second suture curved backwards above and diverging 

 from the hinder one on the sides ; front suture scarcely continued 

 on the sides, but there is a lateral suture near the front of the 

 pleura, curving backwards below. Pectoral tubercle large and 

 thick, obtusely rounded, broader than long. Pleura long, pro- 

 jecting a little on the middle edge below, and rounded. Hind 

 femora thick, not much narrowed towards the extremity and 

 denticulated above. Hind tibiae with six outer and eight inner 

 spines, and provided with five terminal spines, the middle one 

 inferior, as long as the metatarsus, hairy, with a strong tooth on 

 the upper surface before the extremity. Metatarsus trilobate 

 beneath ; second joint short above, but with a projection below 

 the base of the terminal joint ; the latter is slender, with large 

 claws and pul villus, and a little shorter than the metatarsus. 

 Male with the cerci very broad, somewhat spatulate at the 

 extremity, and furnished with a short black terminal tooth on 

 the outer side. Female with the upper appendages longer than 

 the lower ones and hooked upwards at the extremity ; the lower 

 appendages hooked downwards. 



A remarkable and interesting genus, which I had characterized 

 as new before recognizing its identity Avith CalojJtenopsis \ and 

 as my definition was already in print, I have allowed it to stand. 

 My definition, of course, is taken from C. johnstoni. 



There are now several species of Caloptenopsis known, chiefly 

 from East and Central Africa.

Long. Corp. cf 17, $ 21 millim. ; exp. al. ^ 25, $ 40 millim. 



Rufo-testaceous ; face not carinated, clypeus broad below, with 

 a black spot at each lower angle. Pronotum varied with blackish 

 in the middle above, especially in front ; the inner borders of the 

 lateral carinse closely punctured ; the hinder lobe and the meta- 

 pleura thickly and closely punctured. Front of the pleura, below 

 the lateral carinse, with two large pits, the first double, below 

 these is a brown curved band, ceasing at the hinder suture ; 

 below it is a second but shorter brown stripe. The colour of the 

 pleura is paler than the upper part of the pronotum. Subalary 

 spaces with large pvmctures. Both surfaces of the hind femora 

 with cvirved or slightly angulated black lines, followed by black 

 dots on the carinse ; the spaces between the outer and middle 

 carinse above and between the three lower carinse unspotted. 

 Upper curve of the knees black on both sides, space below this 

 yellowish. Tibial spines rather small and tipped with black. 

 Wings brownish hyaline, interspersed with brown network- 

 patterns in the middle, becoming more macular towards the 

 extremity ; anal area with reddish nervures. 



Described from three males and four females from Baringo, 

 Pec. 20, 1899.
