THE CANADIAN ENTOMOLOGIST. I7i 



hyaline, veins brown ; the whole surface is covered with a fine brownish 

 pubescence. Described from one ^ specimen reared from a bee, Osmia 

 species, living in Catalpa twigs. 



This genus shows strong affinities with Cleonymus Latreille and 

 Aetroxys Westwood, but is readily distinguished from both by the thickened 

 fore femora ; had it not been for this character I should have placed it in 

 the genus Cleonymus. 



Chiropachys Westwood. 



Chiropachys colon Linn., Faun. So. Ed., ii., p. 413; C. quadrum 

 Walk., Ent. Mag., iv., p. 14; Pteromalus bimaculatus Swederus. 



This common European chalcid must now be added to our fauna, 

 specimens having been taken in the United States that cannot be separ- 

 ated from types received from Europe. 



The species described by Mr. Edward Norton as Chiropachys 

 nigrocyaucus, Trans. Am. Ent. Soc , ii., p. 327, is not a Chiropachys, but 

 belongs to the genus Pachyneuro7i in the tribe Sphegigastrides. 



Di?iotus Fdrster. 

 Dinotus elongatus n. sp.
