204 PROF. M. BEZZI. 



Type (J, tjrpe 5 and an additional female specimen (British Museum) from British 

 East Africa, Kabete, 28.viii.1914 "on window" (T. J. Anderson); a female 

 specimen without antennae from N. Nigeria, Zarda, " ovipositing in vegetable 

 marrow " (P. H. Lamb) seems also to belong here. 



7. Lonchaea (Carpolonchaea) plumosissima, Bezzi. 



In fully coloured specimens the wings are sometimes yellowish fuscous on the 

 fore half. 



There are specimens from the type locality, Gold Coast, Aburi, January-February 

 1911, " from kola pod " (L. Armstrong) ; and from the same locality, 1912-13 

 ( W. H. Patterson) ; and moreover a male specimen from British East Africa, Embu, 

 24.viii.1914 (G. St. J. Orde-Browne) ; thus showing that the species is present even 

 in the east of the Ethiopian Region. 



Puparium. Of the specimens reared from kola pods there is also a puparium, 

 this is elongate, about 4 mm. long, of a shining reddish colour ; the segmentation 

 is not well marked ; the skin is hard, finely rugulose ; the posterior spiracular 

 tubercles are small, black, rounded, approximated, and projecting for about the 

 length of their diameter. 



The Indo- Australian Species. 

 The Indo- Australian species of Lonchaea, s.l., were tabulated by Dr. Kertesz 

 as long ago as 1901 ; many species have been added since by Prof, de Meijere and 

 by me. All the subgenera are well represented, with the exception of the subgenus 

 Dasyops, of which no Oriental or Australian species are at present known ; even 

 in the very numerous Dipterous galls from Java, described by W. and J. Docters 

 van Leeuwen-Reijnvaan, 1901-1916, it seems that there are no galls referable to 

 these flies. 



The species at present known, with the addition of some new ones, can be distin- 

 guished as follows : — 

 1(8). Arista bare or only microscopically pubescent ; only one sternopleural bristle ; 



legs always with the tarsi partly yellow ; squamulae white or pale 



yellowish and with whitish cilia.* 

 2(3). Metallic species of golden green colour, with rather short antennae and 



rather broad jowls ; first posterior cell distinctly narrowed at end ; 



tarsi with only the basal joint yellow, with a black tip . . . aurea, Macq. 

 3(2). Black or bluish-black species with narrow jowls and long antennae, the third 



joint of which is many times longer than the basal ones and reaches the 



epistome ; first posterior cell not narrowed at end ; tarsi more broadly 



yellow. 

 4(5). Only the basal joint of all the tarsi yellow, but that entirely so ; wings 



yellowish ; species more than 4 mm. long . . . . megacera, Kert. 

 5(4). The second joint of all the tarsi also yellow ; wings wholly hyaline ; species 



not over 3 mm. long. 



*The Lonchea? consentanea. Walker 1860, from Macassar and Gilolo, of which the 

 author says nothing: about the colour of tarsi, is described as having white Jialteres, and 

 thus cannot be a member of this genus.
