new Species o/Apiclse. 497 



Bombay, is a typical Dio.vys, very much resembling B. cincla, 

 Jur. 



Through the kindness of Dr. G. Sevevin and Dr. H. 

 Schouteden I have been able to examine a number of the 

 Vachal types contained in the Museum d'Histoire naturelle, 

 Brussels, and the Congo Museum, Tervueren. 



The following species require notice: — 



Type in Congo Museum. 



Megachile brachiata, Vach. (1909) = Megachile (Amegachile) fim- 

 briata, Srn. (1853). 



Types in Brussels Museum. 



Megachile excesa, Vach. (1903)=Megachile (Amegachile) bituber- 



culata, Kits. (1880). 

 Megachile meles, Vach. (1903) = Megachile armatipes, Fr. (1909). 

 Megachile stuppea, Vach. (1903) = Megachile cincta, F. (1781) (type 



' inB.M.). 

 Megachile ancillula, Vach. (1903) = Megachile vexusta, Sin., $> (1854) 



(type in B.M.). 

 Megachile strict ipalmis, Vach. (1903) = Megachile vexusta, Sm., <$ . 



Type-specimens of Megachile bouyssoni and M. devexa, in 

 both cases males, were also examined. Both come from the 

 same locality (Chutes de Samlia) and appear to be identical. 

 Possibly the females have good characters for separation. 



Trigona cearina, Vach. (1903) = Trigona camerooxexsis, Fr. (1900). 

 Trigoxa bexoiti, Vach. (1903)= Trigona clgpeata, Fr. (1909). 



Melipona punctata, D. T. 



Trigoxa puxctata, Sm. (1854) == Trigona mellarius, Sin. (1862) = 

 Trigona perilampoides, Cress. (1878J. 



Smith's type of T. mellarius is in very poor condition, but 

 it is certainly co-specific with his T. punctata, described at 

 an earlier date. There is a specimen of T. perilampoides in 

 the British Museum from Cresson's own collection, presented 

 to Frederick Smith. The coarse thoracic puncturing of this 

 species is very characteristic. 



Megachile luangwee, nom. nov. 



Megachile (Eumegachile) neavei, M.- Waldo, Ann. & Mag. Xat. Hist. 

 (8) x. p. 473 (1912). 



A species of Vachal's (Ann. Soc. ent. Beige, p. 309, 1910) 

 had already received this specific name.
