gardens there, the other flying on my table at night. Of late, 

 however, I have been more fortunate taking considerable numbers 

 of them in the Cinnamon gardens of Colombo in holes, made by 

 the rooting up of weeds, into which they had run and could not 

 escape, the loose sand giving way under them whenever they 

 attempted to do so. When wishing to find them I had to search 

 the corners of these holes, where some leaves had usually collected, 

 when I have sometimes dug up eight at a time, frequently rather 

 deep in the sand. They are quick of motion aud being thus 

 pursued immediately bury themselves in the sand. 



On reconsidering the peculiarities which so effectually distin- 

 guish this species from the 3 others known, and which I have 

 thought it not superfluous to set forth at such length, I am doubt- 

 ful whether there is not ample reason for forming it into a new g. 

 unless indeed the other species were very imperfectly known and 

 described, which latter I almost suspect with regard to the foot- 

 brushes of the male. If, however, otherwise the diagnosis as 

 given by Lacordaire requires at all events to be entirely recast 

 and the g. to be removed from the tribe Cratoceridse, (one of the 

 characteristics of which is the want of foot-brushes in the male) in 

 which he has placed it ; and, this being agreed to, I would, taking 

 all its peculiarities into consideration, propose to carry out Lacor- 

 daire's idea and to form it into a new tribe " Cyclosomidse" to 

 which it appears as much entitled as the g. Omophron.
