 Description of a new Species of Anopheles, Bi/ J. F.

[To the Editor of the Zoological Journal.] 



My dear Sik, 



The observations contained in the foregoing letter are highly- 

 interesting, inasmuch as they relate to the entomological produc- 

 tions of an hitherto unexplored part of the country ; and as they 

 have been submitted to my perusal, with your permission I pur- 

 pose to add a few remarks. With respect to the insect termed 

 a permanent variety of Poecilus cupreus, I conceive that it 

 ought to be considered as a distinct species, especially as it 

 appears confined to one spot, and has not as yet occurred in 

 England, where Pcbc. cupreus abounds in every pathway and 

 high road during the .spring and summer months. The same ob- 

 servation will apply to the Omaseus ?, which may probably be 

 synonymous with some of the continental species with rufous 

 femora. 



Dyschirius is composed of a great number of closely approxi- 

 mating species, which, as I have elsewhere shewn,* are very 

 difficult to be understood without actual comparison of specimens. 

 I cannot therefore undertake to assert that the above-described 

 insect is novel ; but I rather suspect that it is, and have affixed the 

 name ceratus thereto. 



Hylobius Abietis does not occur within 80 miles of the me- 

 tropolis, I therefore cannot from experience say any thing of its 

 habits ; but, although it is usually taken in fir plantations, my 

 friend, Dr. Leach, picked up a specimen in a marshy situation in 

 Devonshire, about three years since, at a distance from any fir or 

 pine-trees. 



The addition of a third species of Anopheles, proves incon- 

 testably how limited our knowledge of species remains, arising
