often the case ; though sometimes the portion of the thorax behind this 

 streak is reddish orange to the tip, and in perfectly fresh specimens the 

 transverse stripe is made up of raised scales ; the oblique white costal 

 streak has its tip produced a little towards the apex, and is margined 

 behind the tip with brown scales. There are two dark brown hinder mar- 

 ginal lines, one at the base of the cilias and the other at their tips and 

 running out into the hooks. The abdomen and legs are silvery yellowish 

 and the upper surface of the abdomen is stained with fuscous. 



LAVERNA. 



L. circumscriptella Zell. 



I have not seen Prof. Zeller's specimens, but I have received from 

 Miss Murtfeldt specimens which, with the aid of Prof. Zeller's figure and 

 description, I recognise without difficulty as belonging to this species. The 

 thorax* head and palpi are white, except that the basal part of the second 

 joint of the palpi is stained with brownish. The fore wings are of a pale 

 grayish ochreous, with the dorsal margin from the base nearly to the middle 

 snowy white, the white crossing the fold at the base, and further back 

 again crossing the fold and reaching almost to the costal margin ;• it is 

 margined behind by two small tufts of raised brown scales, as represented 

 in Zeller's figure, and there is another one on the costa not represented in 

 the figure, which again has a minute brown spot in the white at about the 

 basal fourth, which I do not find in my specimens. The figure also gives 

 a very distinct white streak which leaves the white of the dorsal margin at 

 the fold and curves to the costal margin before the ciliae ; this streak is 

 absent in one of my specimens and much less distinct in the other than it 

 is in the figure. There is a black speck at the hinder angle (indistinct in 

 my specimens) and the apex is dusted indistinctly with brown. A/, ex. 

 $y 2 lines. 



Miss Murtfeldt informs me that " The larva is a pale, glossy, green, 

 cvlindrical worm, which feeds upon the immature seeds of CEnothcra and 

 pupates within the capsules." 



A single $ from Texas, and one bred $ also from there, lack the 

 curved white line on the fore wings figured by Prof. Zeller, and in some 

 of the other females it is indistinct.
