apically than basally, the third discoidal basally narrowed and 

 pointed. Hind wings with but t\vo complete cells ; a large 

 anterior, extending to shortly beyond the centre with its apex 

 broadly rounded ; and a shorter posterior, not extending to the 

 centre of the anterior, with its apex straight and suboblique, 

 formed by the anterior nervure constituting " one piece, it being 

 iu one continuous rounded curve ; the second nervure is joined 

 to it by a transverse nervure."

This genus is said to be closely related to Ayrypon, Fiirst. 

 (Verh. pr. Kheinl. 1860, p. 151), as" defined by Ashmead (Proc. 

 U.S. ]Sat. Mus. 1900, p. 89), and to be readily recognised by the 

 total lack of apical uervures in the hind wing. I have not seen 

 the single known species.

Clatha lonyipes, Cameron, Spolia Zeylanica, 1905, p. 130 (? <f ).

 lateral lobe, the scutellar fovea, a discal and two lateral stripes on 

 the metanotum, and basal metapleural lines, black ; metanoturn 

 closely reticulate ; pleurae coarsely and rugosely reticulate, 

 with the centre of the propleime striate and with black lines, 

 inesopleurae with narrow black lines and centrally striate. 

 Sciitellum black at base and apex. Abdomen with the two basal 

 segments rufescent, as long as the thorax, slender and of equal 

 length, with the first apically broadened (the remaining portion 

 missing). Leys densely and shortly pilose ; the anterior yellowish

* Ashmead in 1900 revived the name Tkeridium, Curt., fortbis geaus, since 

 it was so called by Forster (Verh. pr. Rheiul. xxv, p. 145) in 1868, though he 

 did not know the reference. The latter's application is, however, entirely 

 arbitrary and incorrect. The genus Tfterivn- was erected, with no description, 

 by Curtis in his " Guide " of 1829, col. 101, and of 1837, col. 112; it is
