different parts of Africa, and these may deserve only subspecific rank, 

 but it seems probable that we may recognize several closely allied but 

 distinct species. 



MESOTRICHIA TENUISCAPA (Westwood). 



Buitenzorg, Java, March, 1909 (Bryant and Palmer). Described 

 by Westwood under the subgenus Platynopoda of Xylocopa, but re- 

 ferable to Mesotrichia in the broad sense. 



XYLOCOPA FENESTRATA (Fabricius). 



Chikar Kot, North West Provinces, India, April 1, 1906 (Frank 

 Benton); Wazerabad, Punjab, April, 1906 (F. Benton). 



XYLOCOPA COLLARIS, variety BRYANTI, new variety. 



Male. — Length 19 mm. Agreeing with X. coUaris Lepeletier in 

 structure and appearance, but wings darker; a good deal of black 

 hair on front; middle tibiae with black hair posteriorly, and their 

 tarsi with long black hair externally and behind, except on the last 

 three joints; hind tibiae with the hair on inner and posterior sur- 

 faces all black, and their tarsi with black hair, except a very little 

 pale at base in front. The wings have a beautiful violet tint. 



Buitenzorg, Java, April, 1909 (Bryant and Pahner). 



Type.— C^t. No. 20701, U.S.N.M. 



Lepeletier described X. dejeanii, now referred by authors to coUa- 

 7'is. from a male in the Dejean collection said to come from Java. 

 It agrees with the present insect in having the hair of the thorax 

 pale (though in hryanti there is a band of black hair along extreme 

 base of scutellum), and the pale hair of abdomen above confined to 

 the first two segments (though in hryanti it fails to reach the apical 

 margin of second segment in the middle third). On the other hand, 

 the base of mandible has only a yellow spot, as in other collaris forms 

 (Lepeletier may be misleading where he seems to infer more), the 

 tegument of the thorax is distinctly greenish (Lepeletier says black, 

 as in the Indian form hinghami Cockerell), the long hair fringing 

 apical part of abdomen is all black (Lepeletier says red and black 

 mixed), and the hair on four posterior legs is as described above, 

 the black fringe abruptly separated from the white on middle tarsi 

 (Lepeletier says white, mixed with black hairs). It is thus evident 

 that our insect is not the true dejeanii., but whether it is a distinct 

 subspecies (as seems probable) can not now be decided. 



XYLOCOPA PICTIFRONS Smith. 



Male. — Soochow, China (N. Gist Gee, 141). The scape is curved 

 and entirely black. This is Smith's male pictifrons; Bingham's is, 

 accordina; to Maidl. X. attenuata Perez.
