1875.} SIR VICTOR BROOKE ON A NEW DEER. 261 
primaries straighter, the spot in cell perpendicular, the median 
streaks longer, the central nebulous fascia less defined ; body dark 
grey ; pterygodes almost entirely chocolate-brown ; abdomen with 
lateral black spots smaller, less defined ; wings below paler; the 
transverse discal brown streak scarcely visible in primaries, and 
further from outer margin ; ventral blackish spots larger. Expanse 
of wings 3 inches 7 lines. 
«KE. Indies. Probably from Scinde”’! (Warwick). Type, B.M. 
Notwithstanding the general similarity between this species and 
H. pinastri, I have no doubt that it is distinct. It is probable, from 
what we know of the metamorphoses of the Sphingide, that the 
larvee of the two species are much less alike than the imagines. 
59. HyLo1cus UNIFORMIS, 0. sp. 
Allied to H. asiaticus, but altogether smaller, paler ; the markings 
less defined, excepting two central waved transverse grey bands 
across primaries ; the abdomen uniform whity brown, without lateral 
black and white spots; fringe whitish ; wings and body below uni- 
form sericeous whity brown. Expanse of wings.2 inches | line. 
N.W. Himalayas. Type, coll. F. Moore. 
This is by far the smallest species in the genus. It may at once 
be distinguished from H. pinastri and allies by the uniform greyish 
or whity-brown colour of the abdomen.
