that in his opinion Plumarm^ Philippi was identical with Neonennis 

 Haliday. Ashmead had placed Plumanus in the Microgastennae. 

 near Neo-neunis^ but evidently did not regard it as very similar to this 

 genus. Recently Bengtsson*^ has published an admirable paper, in 

 which he has clearly defined the genera N eonem^s and Elasmosonia^ 

 has shown beyond dispute their intimate relationship, both struc- 

 turally and biologically, and has erected for them the subfamily 

 Neoneur'mae. This author points out that Ashmead was undoubtedly 

 wrong in placing Ecclites Foerster in synonymy with Neoneurus^ for 

 Foerster described Ecclites as possessing only two cubital cells in the 

 fore wing, while Neaneurus has three. 



In a consideration of the genera constituting the Neoneurinae and 

 the Micro gasterinae, Plumanus can now be disregarded. Recently 

 Dr. J. C. Bradley of Cornell University, on an examination of 

 Philippi's type, found that it is not an ichneumonoid ; he will un- 

 doubtedly shortly define its systematic position,^ Ecclites Foerster 

 certainly can not be considered a microgasterine genus, and in all 

 probability is not neoneurine. Its position is A'ery doubtful; but I 

 am inclined at present to place it in the Bladnae. Neoneurus Hali- 

 day and Elasinosoma Ruthe will make up the N eoneunnae ; while 

 the MicTogastemnae will comprise the following genera: OligoneuruH 

 Szepligeti, Mesocoelus Schultz, Mirax Haliday, Adelius Haliday, 

 DiiTliOjye Foerster, Apanfeles Foerster, ]\[icrogaster T^atreille and 

 Microplitis Foerster. 



Tlie genera Neoneurus, Oliyigonemms, and DiiTlwpe, none of which 

 has yet been discovered in North America, and Mesocoelus Schultz, 

 the only known specimen of which was taken on the Island of 

 St. Vincent and is in the British Museum, are known to me only 

 from literature. I have, however, had the opportunity of examin- 

 ing a very large part of the type material of the North American 

 species contained in the remaining genera, most of which is in the 

 United States National Museum. Only the types of the following 

 have not been seen : Of Microplitis tuchen Viereck, which is in the 

 collection of Kansas University; of Provancher's two species of 

 Microjylitis and four of Microgaster which are in the Museum of 

 Public Instruction in Quebec, Canada; of Microgaster zonarm Say 

 and M. calUptcra Say which have been lost; and of Microplitis 

 coactus Lundbeck which is probably in some European collection. 



Say's two species were sufficiently well characterized, in the origi- 

 nal description to make their recognition comparatively easy. In

' In an address before the Biological Society of Washington, the abstract of which was 

 published in 1021 (Journ. Wash. Acad. Sci., vol. 11, No. 9, p. 214), Doctor Bradley said 

 that riumarius belongs to the family Mutillidae and has tlie genus KonowieUa Andrg 

 as a synonym.
