MESOTRICHIA GABONICA (Gribodo). 



Mount Coffee, Liberia, April, 1897 (R. P. Currie). A male, very 

 like M. anicula (Vachal), but distinguished by the structure of the 

 hind legs. 



MESOTRICHIA STUHLMANNI ALTICOLA, new subspecies. 



Female. — Length about 16 mm.; anterior wing 13.5 mm. Wings 

 very dark, not noticeably pale at base; face covered with silvery- 

 white hair, which extends far up on sides of front ; dorsum of thorax 

 posterior to level of wings, and whole of dorsal surface of first ab- 

 dominal segment, covered with bright yellow hair; mesopleura with 

 black hair; tegulae with a large ferruginous spot on outer side. 

 Male with flagellum red beneath ; thorax above covered with yellow 

 hair; yellow hair of abdomen beyond first segment sparse; wings 

 paler than in female. 



Mount Kilimanjaro, 2 females, 3 males (W. L, Abbott). 



The specimens have been in alcohol, and can not be very satisfactor- 

 ily described, but the yellow on the first abdominal segment will dis- 

 tinguish the insect from true M. stuhlmanni (Kohl). The female is 

 smaller than M. divisa (Klug) , and differs not only in the pubescence, 

 but also in the more delicate punctures of the abdomen. 



Type.— C^ii. No. 20700, U.S.N.M. 



This is very possibly a distinct species ; it is probably the same in- 

 sect which Sjostedt collected on Kilimanjaro, which Friese recorded 

 as Xylocopa caffrariae^ var capensis Enderlein. The name capensis 

 is preoccupied in Xylocopa, and I am confident that our insect is not 

 the same as Enderlein's which came from " Capland " and Port Natal. 

 M. stuhlmanni is also recorded from Kilimanjaro. 



XYLOCOPA BAROMBIANA (Strand). 



Mount Kenia to Fort Hall, British E. Africa, altitude 8,500 feet 

 (E. A. Mearns). Both sexes. Described by Strand as a variety of 

 X. carinata Smith, from which it differs in the male by having the 

 thorax light-haired only anteriorly above, and on anterior part of 

 mesopleura (in the manner of the form producta Smith), and the 

 wings dark as in the female, not light at base. The hind femora and 

 trochanters are both dentate. Strand's type came from Barombi 

 Station in the Cameroons, but it appears to be entirely the same insect, 

 except that ours have an imperfect narrow smooth line on the clypeus, 

 which was absent from Strand's example. The female is almost 

 exactly like X. carinata., but the region just above the top of the 

 eyes is less densely punctured, showing the shining surface, and 

 the smooth band on each side of the clypeus is much narrower and 

 Jess developed. X. carinata is represented by a series of forms in
