Sides of the abdomen parallel. Branches of the forceps remote at the base 

 in both sexes, more or less depressed.

Scudder proposed to change the name of this genus, as there already exist- 

 ed a genus Platylahus , Wesmael, in Hymenoptera, 1845, but his suggestion 

 was not adopted. He still maintains that it is desirable. 



This genus closely resembles Sparatta, and in the form of the 

 antennas it approaches Labia, but it may be distinguished from either 

 by the absence of the lateral folds on the second and third abdominal 

 segments. 



PLATYLABIA THORACICA, Dohrn. 



Head dark-red-brown, the antennae paler ; pronotum yellowish-brown. 

 Elytra and wings black, well developed ; sternum and feet yellow ; 

 abdomen and forceps yellowish-brown, darker near the apex, the anal 

 segment with the hinder border straight ; the pygidium in the $ is square, 

 with a small point in the middle ; the forceps are flat, straight, with a tooth 

 in the middle of the inner margin in the ^, curved gently in at the apex ; 

 the forceps of the 5 are the same as in the $, but without the median 

 tooth. 



In Dohrn's description the forceps are " deutlich sweikantig " on the inner 

 margin, but I am uncertain whether this may apply to the actual edges, or 

 to two projections. 



Length of body, 4-5 mm, of the forceps 1-5 mm. (after Dohrn).

Habitat. — Ceylon (Nietner, Dohrn). 



The specimens which I refer to this species are from Ceylon (Mus. 

 Brussels), and Punduloya, X.97, and V., 97, and Peredeniya, VI., 98, (Green, 

 in. coll, mea.). 



The species also is recorded from Penang (Dohrn), Aru Is, and 

 Ternat (Durb), Burmah, Tenasserim (Borm.), Lombok and Java (coll. mea.). 



I have seen no specimens which correspond exactly with the above des- 

 cription, which is taken straight from Dohrn, but have examined a number 

 of specimens which appear to belong to this species, in which the hesd and 

 pronotum are both shining-black. The forceps are not exactly toothed on 

 the inner margin, but are slightly dilated about the middle, which gives the 

 appearance of two small teeth. The colouration of the head and pronotum
