410 Mr. Bracy Crank on a new Species of Cuterebra. 
duced from Villers, it would appear to be that stumbling-block 
of systematists in entomology, the CE. Bovis of my enumeration *, 
and not of Linnæus, as he states, who, as we have repeatedly 
said, described the Œ. Equi for this species. The Œ. pictus 
of this author, beautifully figured by Curtis in the British Ento- 
mology, no. xxvi. t. 106, I rather suspect to be the faucial bot 
of the Stagt. 
As the species of the new genus Cuterebra were taken for 
CEstri till I separated them, and are closely allied to them in 
their habits, I have ventured at the close of this paper to com- 
municate to the Society a new and undescribed species lately 
received from America, along with some other insects sent me 
by my nephew, Joseph Clark, from the Illinois. |

* The lines on the thorax, and tlie figure of Villers, undoubtedly confirm it. Mei- 
gen’s CE. Bovisis the CE. Bovis of my enumeration, under which this should have come 
as a synonym. 
t I may here observe, that a few days since, in visiting the British Museum, I 
was shown the insect Dr. Leach has called CEstrus Clarkii, and find it only a variety, 
and scarcely that, of the Œstrus veterinus of my enumeration.
