24th I bred a 9 1 which only differs from the % in being considerably 

 larger (expanse .77 inch), and in the dark costal spot being- eon- 

 fluent with the discoidal dark markings, so as to form an elbow. 

 I'erhaps Mr. Walsh intends thus to describe the Y-like mark of 

 the fore wings, which probably exists in the female, while in the 

 male its branches, both the exterior and interior, are almost want- 

 ing. He continues : " I have two captured species in my collec- 

 tion, colored and marked very like gallicolana, but differing from it in 

 the front wing being proportionally shorter in comparison with its 

 breadth, and fiom each other in their markings. I have bred but a 

 single S 9 of this species." 



I have described these various forms as distinct for the reason that 

 the eye detects differences in them, without however believing that 

 they are all specifically distinct. If I should make a conjecture, I 

 should say that G? gallicolana is the true species and that Virgiaiaiut 

 and fulvoroseana are most probably variations of it. There is amongst 

 the Tortrices greater specific variation than in any other group of lepi- 

 doptera, and some of the European variations would be readily pro- 

 nounced from their ornamentation to be true species. 



PTYCHOLOMA? Leach. 



Hind wings, costal and subcostal 

 veins with independent origins. The 

 branches of the subcostal slightly 

 connivent. The median 4-branched 

 the posterior much sepai-ated from 

 the other branches, which are aggre- 

 gated. The cell is closed by a discal 

 vein without branches. 



FoitJ wings, the costa is broadly 

 folded in the S and regularly arcuated in the 9 ; the tip of the wing- 

 is rounded and obtuse, hinder margin oblique, the length rather more 

 than twice the breadth. 



Head and eyes small. Antenn;^ in the S minutely ciliated ; in the 



9 simple. Palpi as long as the head, rather slender, slightly curved and 



ascending to the middle of the face and clothed with sfiort scales; the 



apical joint minute and ovoid ; the middle joint appears to be truncate
