LiNN^us's division Pyralis contains insects varying so much 

 in structure that it is undoubtedly necessary to divide it; and 

 as it is a term which has been appHed to various groups, it 

 will be better to take the first species of Linnaeus as the type, 

 which will include the Herminiae of Latreille with feathered 

 feet and pectinated antennae. 



If structure be of any importance in the formation of groups, 

 it will also be found necessary to divide what are termed by 

 Latreille Pyralites, into two or more families, as some have 

 the maxillary palpi very distinct, whilst in others they are in- 

 visible; some have a very long spiral tongue, and others none. 



In adopting Dr. Leach's arrangement, the term Pi/ralidce 

 has been applied in former parts of this work to unite genera, 

 which might perhaps with more propriety have been called 

 CramhidcE. I am therefore obliged to distinguish the present 

 family by terming it Pyralidcs Curt. 



The genus Hypena contains, 



1. proboscidalis L. — Hub. pi. I.f. 7. — Ha^w. — Sepp. v. 2. pi. 2. 



— ensalis Fab. — e. June and August to m. October 

 amongst nettles. 



2. crassalis F. — Cuii. Brit. Ent.pl. 288. — Achatalis Hub. pi. 2, 



f. 12. ^ pi. '2.1. f. 172 var. ? If the palpi in this figure 

 be correctly given, it belongs to another genus. Mr. 

 Plastead first discovered this beautiful insect in shady 

 groves at Westerham in Kent the beginning of June ; 

 and I have been informed that specimens were taken 

 last year in an old mine near Ashburton, Devon, in 

 August. The caterpillars feed upon nettles and Erica 

 vulgaris (pi. 145). 



3. palpalis F.—Hiib. pi. 2./. 9.— Haw. 366. 2. — In the late 



Mr. Francillon's Cabinet. 



4. obesalis Treit. — crassalis Hub. pi. 2.f. 8. — Haw. — In Mr. 



Haworth's Cabinet. 



5. rostralis L. — Hub. 2.f. 10. — Haw. 366. 4. — End of June, 



the caterpillar feeds on the hop, nettle, &c. 



6. vittahs Haw. 367. 5.— radiatalis? Hub. pil. 20. f. 134. This 



insect is so badly represented, that it is uncertain 

 whether it be intended for Mr. Haworth's species. 

 Mr. Haworth remarks, " The last 5 species are all uncom- 

 mon in England. By the woi'ks of HUbner they appear like- 

 wise to inhabit the continent of Europe, except vittatiis ; and 

 what is more remarkable, I have seen them all from North 

 America." Not one, excepting the 1st, has hitherto been 

 figured in this country. 



The plant is Urtica dioica (Common Nettle).
