The division of Fabricius's genus Hylotoma has been already 

 explained in the account of Cryptus (fol. 58) : it is therefore 

 only necessary here to observe, that, independent of the diffe- 

 rence of the instrumenta cibaria, there are external characters 

 that fully justified Dr. Leach's separating that genus from 

 Hylotoma; the simple antennae in both sexes in Hylotoma, the 

 branch from the marginal cell of the vikings, and the spines of 

 the 4 posterior tibiae, are the most remarkable. The genus as 

 it now stands contains 14< British species, which I shall here 

 enumerate, observing that the first may possibly belong to Le 

 Peletier de Saint- Fargeau's genus Ptilia. 



HYLOTOMA 



1. pilicornis Leach. 8. Klugii Leach. 



2. Berberidis Klug. 9. segmentaria Panz. 



3. Anglica Leach. 10. coerulescens Fab. 



4. enodis Linn. 1 1 . femoralis Klug. 



5. \io\acea Klug. 12. Rosse Lm?i. 



6. coerulea Klug. 1 3. Stephensii Leach. 



7. ustulata Linn. 14. pagana Panz. 



Our species (of which a female is figured) was first disco- 

 vered at Darent Wood, Kent, by J. F. Stephens, Esq., in 

 honour of whom it was named by Dr. Leach. It is nearly 

 allied to H. pagana, from which it differs in having more trans- 

 parent wings, brown and pubescent tibiae, and black tarsi : it 

 appears to be a local species, as I have never met with it my- 

 self, excepting at Darent, where it is taken in June, in which 

 month all the species above recorded are to be found. 



Stachys sylvatica (Hedge Wound-wort), referred to in folio 

 61, is figured with the insect.
