THE CANADIAN ENTOMOLOGIST. 223 



to the Mas ar idee and the Eumenidce, and hence I begin with them, rather 

 than with the Amisegincv, as Mocsary lias done. 



This paper was ready for publication when I received the July No. 

 of Zeilchr. f. Hym. n. Dipt., in which Mr. Adolphe Ducke has established 

 a new subfamily, the Pseudepyrince, based upon a new genus discovered in 

 Brazil. 



This subfamily, judging from the description alone, is hardly 

 justifiable, all the characters given, except those of the abdomen, 

 agreeing with the Allocoelince, and I have here merged it with that 

 subfamily. 



Table of Subfamilies. 



Face more or less convex, never concave ; prothorax quadrate, 

 subtrapezoidal or longer than wide, and as long or longer than the 

 mesonotum : abdomen depressed, subconvex or convex beneath, 

 the female with 2 or 4 dorsal segments, the male with 4 or 5 seg- 

 ments 3. 



Face more or less concave ; prothorax transverse quadrate or rec- 

 tangular, shorter than the mesonotum ; abdomen concave beneath, 

 with 3 dorsal segments, rarely with 4 segments in some males. 

 Maxillae and labium normal, the ligula subcorneal, the galea 



rounded, obtuse 2. 



Maxillae and labium abnormal, the ligula and galea very long, 

 produced into a slender, filiform beak, resembling the pro- 

 boscis of bees, and bent back under the thorax in repose ; 

 front wings with the discoidal cell distinct ; abdomen in § 

 with 3, in <£ with 4 segments, the last without pits or foveola 1 . 

 but with a broad deep submarginal furrow on each side of the 

 apical half; apex of abdomen irregularly denticu- 

 late Subfamily I. — Pamopina; 



2. Third abdominal with a submarginal series of pits or foveolre, con- 

 tained in a groove or declivity, the apical margin rarely unarmed, 

 most frequently angulate, dentate or serrate ; front wings with a 

 distinct discoidal cell ; claws simple. . .Subfamily II. — Chrysidinse. 

 Third abdominal segment without a submarginal series of pits or 

 foveolae in a groove or declivity, the surface therefore entire, 

 smooth ; front wings with the discoidal cell frequently wanting or 

 incomplete ; claws bifid, serrate or pectinate.
