genera and thus correct the numerous errors I have doubtless commit- 

 ted, by describing new generic groups, when genera have ah-eady been 

 created into which they could have been received and of which I have 

 no knowledge. 



Therefore, rather than describe the following insect under a new 

 generic name, I prefer to place it here provisionally. 



Tortrix! fumiferana. — Fore wings brown, varied with dark brown, short 

 strise. The basal patch is indicated by dark brown strife, but the central fascia 

 is not indicated. Following the basal patch is a grayish-brown space having 

 a shining lustre; its exterior edge is irregular and it widens towards the dorsal 

 margin, where it bears short, dark-brown strise. About the middle of the costa 

 is a round spot of the same hue and lustre, and along the terminal margin is a 

 stripe with irregular margins, of the same hue and lustre bordered on each side 

 with dark brown. 



Sometimes the grayish-lustre is absent on the markings, which are then 

 sim2)ly of a paler brown than the general hue. Hind wings dark fuscous.

HALONOTA, Steph. 

 Proc. Acad. Nat. Sci., Aug. 1860, p. 357. 

 Halonota tautana, n. s. — Fore wings dark brown, having a coppery hue. The 

 basal patch is large and well defined, and of the general hue. It is limited 

 exteriorly by the dorsal blotch which is grayish with a violet hue, and is con- 

 nected with the first geminated costal streak, containing a short, brownish 

 line. Thence to the apex, the costa is streaked alternately with brownish and 

 geminated with lustrous gray. Exterior to the dorsal blotch are two lustrous 

 gray, transverse streaks. The hinder margin is sjjotted with black. Hind 

 wings fuscous, with a coppery hue.

LEPTORIS,* n. gen. 

 Hind wings rather broader than fore wings, costa slightly arched in 

 the middle, apex somewhat acute, apical margin slightly concave. 



The costal and subcostal veins have a common base. 

 The branches of the subcostal are divergent from the 

 origin of the discal, wliich is regularly curved. Me- 

 dian vein 4-branched, three of which are rather ag- 

 gregated, the posterior remote. 



Fore wings, costa not dilated at the base, regularly 

 arched; apex acute; apical margin slightly excavated
