Show 1902.] BRITISH EAST AFRICA AND UGANDA. 101 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, projecting a little on the middle edge below, and rounded. Hind femora thick, not much narrowed towards the extremity and denticulated above. Hind tibia? 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 pulvillus, 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 with Caloptenopsis; and as m y definition was already in print, I have allowed it to stand. M y definition, of course, is taken from C. johnstoni. There are now several species of Caloptenopsis known, chiefly from East and Central Africa. 23. CALOPTENOPSIS JOHNSTONI, sp. n. Long. corp. <? 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 carina? closely punctured; the hinder lobe and the meta-pleura thickly and closely punctured. Front of the pleura, below the lateral carina?, 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 punctures. Both surfaces of the hind femora with curved or slightly angulated black lines, followed by black clots on the carina?; the spaces between the outer and middle carina? above and between the three lower carina? 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, Dec. 20, 1899. |
