ii Mr. H. T. Stainton's 



wings somewhat lanceolate, but rather rounded at the anal angle (thus, broader than 

 in Lithocolletis). 



The perfect insect has a peculiar way of sitting (only using four feet), with its head 

 inclining towards the object on which it is resting at an angle nearly of 45°. 



The larvae of those species of which the transformations are known " feed on the 

 leaf-buds and flower-buds, and have the head and prothorax rather hard, so as to fit 

 them for boring the buds. And the transformation takes place," according to Zeller, 

 " more rarely in the habitation of the larva than in a place of concealment behind 

 bark, or among moss, or in the earth." 



It is not very easy to group these insects naturally. I have followed Zeller's 

 arrangement,* except in the position of Andereggiella, which appeared to me more allied 

 to curvella (cornella, Z.) than to ephippella (pruniella, Z.) 



* Zeller's arrangement is as follows : — 



" I. Palpi graciles, squamis appressis. Alae auteriores laevigata?, vitta dorsali alba, 

 aut unicolores. Venae ex cellulae discoidalis parte postica novem oriuntur. Oviductus 

 2 plerumque exsertus. 



A. Alae anteriores vitta dorsali alba, variisque signis ornatae. 



a. Vitta dorsali alarum anteriorum semel tantum interrupts (Argyresthia pr. 



Ismene, St.) 



1. Andereggiella, F-v-R. 2. pruniella, L. 3. nitidella, F. 4. spiui- 

 ella, F-v-R. 5. fagetella, Mor. 6. coujugella, Z. 7. pulchella, 

 Lienig. 8. tetrapodella, L. 9. glaucinella, Z. 



b. Vitta dorsali al. ant. bis vel saepius interrupta. 



a. Minores. 



10. fundella, TV. 11. retinella, Z. 12. abdominalis, Z. 13. di- 

 lectella, Z. 

 0. Majores (Argyrosetia, Steph.) 



14. cornella, F. 15. sorbiella, Tr. 16. pygmaeella, H. 17. Gcedar- 

 tella, L. 18. Brockeella, H . 



B. Alae anteriores unicolores. Venae ex cellulae discoidalis parte postica octo ori- 



untur. Femina plerumque mare minor (Blastotere, Ratzeburg). 



19. arceuthina, Z. 20. certella, Z. 21. praecocella, Z. 22. illumina- 

 tella, F-v-R. 23. glabratella, Z. 24. amiantella, Kollar. 



II. Palpi breviusculi, incrassati, pilosuli. Alae anteriores pulverulentae, fascia ante 

 medium signatae. Cellula discoidalis postice venas octo sexve emittit. Oviductus $ 

 absconditus (Cedestes, Z.) 



25. Gysseleniella, Kuhlw. 26. farinatella, Z." 



Of these species, six— viz. pulchella, sorbiella, illuminatella, glabratella, amiantella 

 and Gysseleniella — have not yet been detected in this country ; on the other hand, we 

 have three species in this country not known to Zeller, — viz. purpurascentella, semi- 

 fusca and literella,— though of this latter I have considerable doubts whether it be 

 truly distinct from Gccdartclla.
