available for study, so attention can only be called to these characters. 

 In Strongylogaster the third pleural suture is gently curved and the 

 metepimeron is small. In Selandria the third pleural suture is 

 angulate and the metepimeron forms an irregular L-shaped plate. 

 In Eustromboceros the third pleural suture is sub angulate, but the 

 angulation is near the middle, and the two plates are of about the 

 same size. In some genera when the metepisternum is large, as in 

 Selandna, there is a cephal-caudad suture from near the middle of 

 the coxa. Other differences have been noted, but these will suffice 

 to show the variation in the metapleurge and the possibility of it as a 

 valuable character in classification. When sufficient material has 

 accumulated, a tabular arrangement of these characters will be given. 



Genus NESOSELANDRIA Rohwer. 



NESOSELANDRIA CEYLONENSIS, new species. 



Differs from Nesoselandria imitatratrix (Ashmead) in the different 

 conformation of the head (more especially in the frontal area); the 

 more strongly tapering antennae; truncate stigma and other charac- 

 ters. 



Female. — length 4 mm. Labrum truncate; clypeus truncate, lat- 

 eral angles sharp; supraclypeal foveae deep, confluent with the an- 

 tennal fovese; supraclypeal area large, flat; middle fovea, rather 

 shallow, nearly circular in outline; frontal fovejB similar in shape to 

 the middle fovea, but larger; from each lateral ocellus to the irregular 

 frontal crest is a fine carina; postocellar area defined laterally by an 

 elongate, punctiform fovea, otherwise not defined; postocellar line 

 sub equal with the ocellocular; occiput sharply defined; antennae 

 hairy, tapering apically, the thu*d jomt about one-fourth longer than 

 the fourth; stigma broadest between the middle and the base, taper- 

 ing to the narrowly truncate apex; sheath concealed. Black; tarsi 

 white, infuscated. Wings brownish, hyaline; venation dark brown; 

 hind wings paler than the fore wings.

Taxonus (Nesotaxonus) Rohwer, Proc. U. S. Nat. Mu3., vol. 39, No. 1777, p. 111.

 the tribe Selandrini of the classification proposed i\i Proc. Ent. Soc. 

 Wash., vol. 13, No. 4, p. 224.
