posterior: antennae inserted higher than usual, setaceous; the scape 

 about one-fifth the length of the entire organ, very robust, being 

 nearly twice as thick as the base of the flagellum, and curved 

 slightly at its base ; the carina?, behind which they are inserted, termi- 

 nating above abruptly, in front of the anterior ocellus, where they are 

 very prominent, and beneath the insertion of the antennae dilating late- 

 rally and inclosing a large circular concavity, and terminating on the 

 edge of the clypeus on each side in a recurved compressed acute tooth : 

 mandibles slender, leaving scarcely any space between them and the 

 clypeus. 



Thorax excessively gibbous in front, pendent over the head ; metathorax 

 perpendicular : wings rather darkly tinged, their nervures testaceo-fus- 

 cous ; the stigma testaceous, with a minute brown spot at its base : 

 marginal cell yellowish, lanceolate, slightly acuminated beyond the se- 

 cond submarginal, which is about the same size as the first, from which 

 it is separated by an inwardly curved transverse cubital ; it receives the 

 recurrent at about half its length, beyond which to the termination 

 of the cell the cubital nervure is slightly thickened : legs short and ra- 

 ther stout. 



Abdomen slightly shining and slightly laterally compressed ; its first seg- 

 ment transverse-quadrate, transversely convex at its apex, about as 

 wide as the second, which with the following are transverse and short, 

 and but slightly constricted at their margins, the terminal segment 

 vertically much compressed at its extreme apex, beneath which the 

 sexual organ protrudes as usual. 



In my own collection. 



This species is amply distinguished from all by the peculiarity of 

 the carina? of the face, the clypeus, the remarkable thickness of the 

 scape of the antennae, and the excessive gibbosity of the mesothorax 

 in front. I have much pleasure in dedicating it to Mons. Guerin, 

 the able illustrator of many genera of Hymenoptera.

Neuchatel, June 12. — Recent accounts have been received from 

 the naturalist Tschudy, who some years ago, assisted by the late 

 King of Prussia and some other gentlemen with four thousand francs, 

 went out with the Edmond to Lima, in order from thence to make 

 excursions into the Cordilleras and adjacent country. A consider- 

 able transport of objects of Natural History collected for the Museum 

 of our town (Neuchatel) has already come to hand. He is still in 

 the mountains of Peru ; and having consumed the money taken out 

 with him, lives by the chase, and is awaiting fresh assistance wliich
