NEW AND LITTLE-kNOWN SPECIES OF 211 



INDO-MALAYAN HYMENOPTERA. 



" Sphex flava, Fair. Ent. Syst. ii, 217, 80; Pompilus flavus, Fahr. 

 St/St. Fiez., p. 197,52; St. Farg. Eym. iii, 430, 21; Hemipepsia 

 flava, Dahlh.Hym. Europ. i, 123, 1." 



Here Smith identifies the Sphex fiava of - Fabricius with the 

 Hemipepsis fiava of Dahlbom, but keeps the Sphex severa of Drury 

 distinct. Later on in his Catalogue of the Aculeate Hymenoptera and 

 Ichneumonidce of India and the Eastern Archipalego, published in 

 1867 in the Journal of the Linnean Society, vol. si, at page 357, he has 

 *' Gen. Mygnimia, Schuck.

Here evidently two species, Sphex severa^ Drury, and Sphex fiava, 

 Fabricius, are confused together. The reference, fig. 4,- pi. 42 of 

 Drury's work, represents severa, a fairly common species in Burma, of 

 which I give a figure, PI. II, fig. 1. This species is also very constant 

 in form and colour, I have only one specimen, and that is from 

 Sumatra, which varies in being a dusky black all over and having the 

 basal half of both wings fuscous shot with purple* 



Cameron (Mem. and Proc. Manch. Lit. and Phil. Soc, 4th series, vol. 

 iv, Pt. iii., pp. 443-445) and I (Journ. Bom. Nat. Hist. Soc, vol. v, 

 p. 371), following Smith, have fallen into the same error in giving the 

 synonyme of the two species. 



In the Ann. and Mag. Nat. Hist, Series iv, vol. xii (1873), p. 257, 

 Smith describes a large Salius under the name Mygnimia intermedia 

 as follows :— 



" Female. Length 16 lines. Black, the head, pro- and mesothorax, 

 and the legs, except the coxse, trochanters, and base of the femora 

 reddish-yellow. The antennse yellow ; tips of the mandibles black. 

 The anterior margin of the pro- and mesothorax blackish ; the meta- 

 thorax black, truncate posteriorly and transversely striated ; the wings 

 flavo-hyaline. Abdomen smooth and shining, 



" Hah. : N. India, Ceylon."
