YI. — Notes on the Asilidae : Sub-division Asilinre. 

 By Gertrude Ricardo. 



The Asilid?e of Australia having been to a certain extent 

 revised and described in the Aun. & Mag. Nat. Hist. [ser. 8, 

 ix. (April, May), x. (July, Sept.) 1912; xi., January, April, 

 May 1913; ser. 9, i., January 1918], this paper is the 

 be";inning of an atteniTDt to briu": the Asilidse of the 

 Oriental and South African Regions into some order, and 

 to name such new species as are to be found in the Brit. 

 Mus. Coll. and others sent me by j\[r. L. Peringuey from 

 the Cape Museum. The genera Machimus, Neoitamus, and 

 Hc'liymoneura are here dealt with. The types are all in the 

 Brit. Mus. Coll., unless otherwise specified. 



Machimus, Loew. 

 Linn. Ent.iv. 1,3 (1849), 



This genus has as yet only been represented in the 

 Oriental Region by Machimus coruscus, V. d. Wulp, from 

 Java, a species unknown to me, and by Machimus atratidus, 

 Wlk., mentioned below. 



The species described from the South African Region are 

 Machimus lepturus, Gerst., from Zanzibar, and Machimus 

 caudiculatus smd penicillatus, Speiser, both from East Africa. 



Ten new species are now described from India and Ceylon, 

 and one from S. China. The South African Region is 

 represented by one new species. 



Asilus atratidus, Walker, from Java, is placed by Wulp 

 in this genus, the type (a female) is in the Brit. Mus. Coll., 

 but in such a bad condition it is impossible to decide even 

 its generic rank. It is a small blackish-brown specimen.
