PORTLAND LEPIDOPTERA. 189 



ELACHISTA ZONARIELLA, Tgstr. Not uncommon (N. M. R.). 



BIATOMELLA, Sta. Recorded Proc. I., 62, as " Rare. The 

 last specimen taken by (C. W. D.), Sept. llth, 1875." 

 It is a little uncertain whether the species which occurs 

 at Portland is Uatomella or triatomella, as the specimens 

 are not labelled. Possibly both may be there. Biatomella 

 occurs in similar spots in Purbeck, but not triatomella. 



., POLLINARIELLA, Zell. Common. 



,, ARGENTELLA, Clerck. Abundant. 

 TISCHERIA MARGINEA, Haw. Common. 



LITHOCOLLETID^E, St. 



LITHOCOLLETIS LANTANELLA, Sclir. Larva not uncommon in Vibur- 

 num lantana. 



POMIFOLIELLA, Zell. Common in hawthorn. 



,, SPINICOLELLA, Kol. Common in sloe. 



,, MESSANIELLA, Zell. One on the undercliff on October 



18th, 1S87 (N. M. R.) 



VIMINIELLA, Sircom. Mines occur on sallow, which 



may possibly be those of salicicolella, but as 

 ciminiella seems to be the only species in the 

 sallows about Weymouth, as well as in Purbeck, 

 it is more probable that it is the species at 

 Portland. Confirmation by breeding is necessary. 



TRIFASCIELLA, Haw. Larva not uncommon in 



honeysuckle. 



LYONETIID^E, Sta. 



CEMIOSTOMA LABURNELLA, Heyd> One near Pennsylvania, August 

 8th, 1887. It is almost impossible to distinguish 

 between the imagines of this species and spartifoliella, 

 but the probabilities seem in favour of this specimen 

 being laburnella.
