20 AMERICAN HYMENOPTERA. 



Westwood gives the following generic description : 

 "Body (male) elongate, abdomen long, compressed, slightly clavate 

 at the apex, petiole and second segment following as long as thorax, 

 the two apical lobes horny, compressed, longer than the preceding 

 segment. Head transverse; narrow in front, the sides, behind the 

 eyes, rounded. Antennae as long as the body ; labium short, trans- 

 verse; mandibles curved, apices deeply bifid; maxillae elongate' 

 slender, ciliate ; maxillary palpi long, slender, five-jointed, the joints 

 of nearly equal length ; last segment slender (a very minute segment 

 not seen by me ?); mentum of maxillary long, labrum very long, bi- 

 partite, lobes filiform, rostrum slender, curved, more than four times 

 as long as the mentum ; labial palpi slender, with four joints of equal 

 length, the apical segment most slender. Thorax obovate, head as 

 wide as the thorax. Wings colored ; the anterior with the small second 

 marginal cell (areolet) wanting, the first submarginal area (cubital) 

 confluent with the discoidal." 



This genus was erected by Westwood for a single species 

 which is still almost unknown, and has been taken but once 

 since the original description.

I have not seen a specimen of this species, and can only 

 give a translation of the original description. 



Type. — cf . Location unknown.* 



According to Cameron's plate the discocubital vein is arcu- 

 ate as in Thyreodon, the nervulus slightly postfurcal, nervellus 

 broken above the middle and the wings fuliginous. 



Distribution. — Mexico (San Angel, Chapultepec). 



This species is apparently tropical, but its range is not as 

 yet known. 



* It is not in the British Museum but may be at Oxford.
