parative with the European argiolas we find among other things that 

 the size is a little smaller than argiolus, the color of the $ a delicate 

 violet-blue above and beneath 'a gray much more obscure than in 

 argiolus' and that it may be distinguished from argiolus by the stout- 

 ness (grosseur) of the row of black dots on underside, (Edwards' 

 translation of grosseur is merely 'size' which might mean larger or 

 smaller). We find all these points admirably borne out by Boisduval's 

 figure (PL 36, Figs. 1, 2) but not at all by the form to which Edwards' 

 would apply the name and which he figures (Butt. N. Am. II, Lye. II, 

 Figs. 8, 9) in which the size is larger than argiolus, the underside is 

 as pale if not whiter and the spots are more reduced. As Edwards 

 himself has said pseudargiolus is nearest violacca and in our opinion 

 this latter name should be sunk as a synonym, as it is only to this 

 form that both Boisduval's description and plate could possibly be 

 referred. Edwards' action was apparently an attempt to retain both 

 his names (neglecta and violacca) and at the same time provide a 

 name for the large summer form. Tutt (Brit. Butt. II, 405) in his 

 discussion of the American forms of C. argiolus offers a good deal of 

 criticism on Edwards' grouping of the various generations of this 

 species and proposes (p. 407) the name ncglecta-major for the form 

 which has been generally regarded as pseudargiolus. 



HESPERIIDAE 



Genus Eudamus Swains. 



We are sorry to say that this genus must fall before Goniurus 

 Hbn. ; the type of this latter genus was specified as simplicius Stoll 

 by Kirby in 1870 (Ent. Mo. Mag. VII, 56) and the type of Eudamus 

 was specified by Swainson as proteus according to Scudder (1875, 

 Hist. Sketch p. 169). These two species being congeneric the more 

 recent generic name Eudamus will become a synonym of the older 

 name Goniurus. Scudder's action in fixing (Hist. Sketch, p. 180) 

 coelus as the type of Goniurus was ultra vires and not in accord with 

 the present rules governing nomenclature ; he is followed in this by 

 Mabille (Gen. Ins. Hesp. p. 23). 



Genus Hesperia Fabr. 



Dr. Dyar in his Revision of the Hesperiidae of the U. S. (1905, 

 Jour. N. Y. Ent. Soc. XIII, 117) has confused the three genera 

 Heliopetes Billb., Scclothrix Ramb. and Pyrgus Hbn. ; this is in part
