290 MR. J. O. WESTWOUD ON NYCTERIBIA. 
Latreille, in his ‘ Genera Crustaceorum, &c.’, after describing his Nyct. Vespertilionis, 
stated, ‘‘ Speciem alteram Indicam possideo ;” and Dr. Leach observed of his Phthiri- 
dium Blainvillii, which he received from M. de Blainville, ‘‘ This is probably the species 
alluded to by Latreille in his Genera’; whereupon Latreille subsequently described his 
insect, which he received from M. Cuvier, as identical with Dr. Leach’s ; giving at the 
same time as its habitat the Isle of France, instead of India, as previously stated by 
him. The species are quite distinct both in colour and size, as well as, it would seem, 
in locality.

I have restored Latreille’s original name to this species, considering it as distinct 
from any of the others, with the exception perhaps of Hermann’s Nyct. Vespertilionis. 
His character, on which mine is founded, is subjoined'.
