7*2 THE CANADIAN ENTOMOLOGIST. 



In a former paper I have referred to H. glandulella Riley some other 

 Texas specimens differing shghtly from typical bred specimens of glandiil- 

 ella and from Prof Riley's description. The form described by Prof. 

 Zellc* as B. mthilclla is one of these, and is, I think, only a variety of 

 glaiidulc/la. Prof Riley concurs with me in this, and he thinks tria?igu- 

 larella and sciaphilella are also varieties of it. I am strongly inclined to 

 concur with him. I have made some remarks on this subject in the 

 former paper. 



Argyresthia ansterella Zell. 



A. imdulatella Cham. 



I have never met with a specimen quite so strongly marked as that 

 figured by Prof Zeller, but I have elsewhere (ante v. 6, p. lo) remarked 

 on the amount of variation in the intensity of the markings of the species. 

 I have known it many years, and while I write (June 3rd, 1876) it swarms 

 in hundreds around ehn trtes in this region. It is not improbable that 

 the dark markings are deeper in more southern localities. Other species 

 of Argyresthia have the habit of undulating or " see-sawing," but none 

 that I have seen practice it to such an extent as this. Prof Zeller first 

 described it. 



Aetole bella Cham. 



Before I saw Prof Zeller's description of Hcliozella gracilis, I thought 

 it not improbable that it would prove to be this species, because of the 

 resemblance in structure of the head and its appendages in the two genera 

 and the fact that both were taken in the same locality, where A. bella 

 seems to be not uncommon. They are, however, quite different creatures. 

 Aetole perhaps approaches Helissiiies as nearly as it does Heliozella. I 

 have, however, no acquaintance with either genus other than through 

 written accounts of them, having never seen a species of either. A. bella 

 resembles Chrysoclista lineella in ornamentation more than it does any 

 other species known to me. 



COLEOPHORA. 



C. bistrigella. 



With fresher specimens before me, I amend the description of this 

 species. Snowy white, in some lights silvery. The fore wings have two 

 rather pale ochreous-yellow streaks from the base, one of which is above
