clxxii Species of Lithocolletis. 



easily be mistaken for a new species : the ground colour is pale tawny, 

 not unlike the palest specimens of Alnifoliella, with a long and rather 

 broad white basal streak, which runs in an oblique direction to the 

 apex of the second dorsal streak ; on the costa are four short white 

 streaks, and on the inner margin three white streaks, all dark-mar- 

 gined towards the base ; their dark margins being the dark streaks of 

 the typical insect : at the apex is the black streak. 



The flight of Tenella is very feeble, and on the wing it may be in- 

 stantaneously distinguished from Cramerella, which flies in jerks. 



11. L. emberizaepennella. "I collected several hundred pupae, but 

 obtained therefrom not a single specimen, since they all dried up." 

 Here we see exhibited on a gigantic scale, one of the great evils with 

 which breeders of Micro-Lepidoptera have to contend, the drying up 

 of the pupae. I believe as good a w r ay as any is to cut out that por- 

 tion of the leaf which contains the pupa, and to place it in some ves- 

 sel that is air-tight, or nearly so. Of course the leaf must not be wet 

 when thus shut up, but in its ordinary state it will contain sufficient 

 moisture to keep the inclosed pupa from drying up. When many 

 pupae are collected, the mass of leaves that would be collected toge- 

 ther, if the whole of each leaf were preserved, would be found very 

 inconvenient. 



12. L. tristigella. By no means the Tristrigella of Haworth, and 

 therefore to be re-named. I have much pleasure in publishing the 

 name Nicellii, proposed for it by Herr Zeller, who says he is himself 

 to blame for Von Nicelli calling it L. tristrigella, the latter having sent 

 him specimens for examination, which he pronounced identical with 

 some not over-fine specimens of Tristrigella I had sent him, and 

 therefore returned them to Yon Nicelli as Tristrigella, Haw., Sta. 

 Herr Zeller regrets that want of time had prevented him from compar- 

 ing these specimens with the description of Tristrigella. 



As the name has been misapplied, it may be as well, to avoid fur- 

 ther confusion, to enumerate the differences between Nicellii and 

 Tristrigella. 



Nicellii has the anterior wings pale saffron, with shining fasciae and 

 spots. Tristrigella has the anterior wings reddish orange, with pale 

 but dull fasciae and spots. In Nicellii there are two fasciae, a pair of 

 opposite spots forming an angulated fascia, and, besides, two small 

 costal spots and a minute one at the anal angle, and an oval black 

 spot at the apex of the wing. In Tristrigella there are two fasciae, 

 and a pair of opposite spots forming an angulated fascia, and, besides, 

 only one single streak extending from the costa a little before the
