truncation not sharply divided from the dorsal surface. Al»- 

 doinen shinini;, very finely coriaceous, witii scattered punc- 

 tures ; the apical segment densely clothed with coarse golden 

 hail 3. The transverse groove near the base of the second 

 sternifo is almost straiglit. Hind tibia? strongly serrate. 

 Second abscissa of the radius loiiger than the third, the first 

 and fourth about equal. First recurrent nervure received at 

 about four-fifths from the base of the second cubital cell, 

 .•second distinctly before the middle of the third cubital cell. 

 Cubitus of the hind wing originating distinctly beyond the 

 transverse median nervure. 



cJ. Clypeus narrower than in the female, the eyes con- 

 verging bolow, not parallel as in the female. Ilind tibia; 

 spined, not serrate. Seventh tergite broadly subtruncate at 

 the apex.

This is the species figured by Bingham (Journ. Bombay 

 Nat. Hist. Soc. 1895) as Sphex Jlaya of Fabricius ; but it 

 does not correspond to the description, several of the apical 

 segments being fulvous in this species, only one \njlava. I 

 Icil confident that Dahlbom was right in his identification of 

 fiuva after consulting the Fabrician collection. Probably the 

 type was in that collection, as Fabricius makes no statement 

 to the contrary. But Fabricius evidently had a vciy confused 

 idea of his own species, as a specimen identified by him as 

 Jiava in the Banksian collection is a female with bifid tarsal 

 ungues, and from his description of a variety in Ent. Syst. I 

 suspect that he has also confused Batozoims iniifasciatmt^ vSm., 

 w'xih Jfava. Bingham, in ' Fauna of British I\idia ' (l.S'J7), 

 after examining the specimen labelled Jiava in the Banksian 

 Collection, still regarded this species as an extreme variety of 

 jiava. But he cannot have noticed the tarsal ungues. In 

 the same work Bingham rightly sinks Privcnemis Immhcrti- 

 atiits, Sauss., as a synonym of //aua, though it is undoubtedly 

 distinct from the specimen in the Banksian Collection. As 

 the matter stands, 1 consider we have three species which 

 have been confused by Bingham under y/aya: — 



1. Cry2)tochiius JinvuSj Fabr. 



Sphex fnva, Fabr. Syst. Ent. p. 352 (1775). 



I'liuvmininjluvus, Dalilb. Ilym. Kvnnj). i. p. 457 (1845). 



I'riocneutif hnvtlitrtiinius, .^'iiii.-s. liii.-f de Nt)varu, Zool. ii.]i. H.'^ (1807). 



Ill this species the tarsal ungues arc unidentate in both 

 sexes.
