the exceptions urged are for exotic species. His own table pub- 

 lished in the same place is open to tlie same objections. Thus under 

 his tribe Evaniiuie he says: "Nervure basale aboutissant au stigma, 

 rarement evanouie dans sa partie superieure." In the genera 

 Hyptia, Setmeomijia, Semieodofjaster, Evaniellus and sometimes Zeii.v- 

 em?uVf, the " nervure basale " is wanting. Again he says : "Abdo- 

 men ellipsoidal chez le male." In Hyptia and others the 



abdomen in the male is round and indistinguishable from that of 

 the female in shape. I think that the characters employed in the 

 following table will be found constant, except that I am not certain 

 whether the folding of the wings is constant in all Fwninaj or not. 

 It is in all cases that have come under my observation. 



TABLE OF THE SUBFAMILIES OF EVANIID.E. 



1. Front wings with the transverse part of M.. present (Fig. 67) ; not folded lon- 



gitudinally ; hind wings without a posterior lobe (Fig. 69) ; nietaster- 

 uum not prolonged into a furcula; abdomen clavate, the basal seg- 

 ment not filiform-petiolate, nor strongly cotitrasted to the second in 



form AULACINiE. 



Front wings with the transver.se part of M-2 absent (Figs. 72 and 76) (2). 



2. Hind wings without a posterior lobe (Fig. 72) ; front wings folded longitudi- 



nally as in Vespoidea; metasternum not prolonged into a furcula; 

 abdomen clavate and compressed, the basal segment not filiform-peti- 

 olate, nor strongly contrasted to the second in form FQ<]NIN.E. 



Hind wings with an almost separated posterior lobe (Fig. 76j ; front wings not 

 folded longitudinally; metasternum prolonged into a furcula between 

 the posterior coxa;; abdomen with the basal segment filiform-petio- 

 late, strongly contrasted to the following segments in form, the latter 

 together compressed, oval ( 1 ), triangular ( 9 ), or nearly round in 

 both sexes EVAXIINM-:.

Following Schletterer, authors have of recent years used Gaste- 

 ruption as the name of the typical genus of this family. But Gas- 

 teruption of Latreille (1797) is a nomen nudum— no species being 

 mentioned. In 1798 Fabricius describes Fcenm with jaculator and 

 imectator as species. Latreille in 1802, Hist. nat. Crust, and Insec, 

 iii, 329, says: " J'avois etabli ce genre avant Fabricius, sous le nom 

 de Gasteruption. ; niais, comme ce dernier mot est trop dur, j' adopte 

 avec plaisir la denomination de ce naturaliste." 



As before remarked, the Fcx'uina' show unmistakable relations to 

 the Stephanidse. 



The wing of Hyptiogaster is the most generalized in the sub-
