coffee-shrubs. I noticed a preparation illustrating this remark- 
able habit for a Cicindelid larva in the museum at Buitenzorg 
in March of this year, but it was inside a locked case, and as 
Dr. Koningsberger was on leave in Europe, I was unable to 
make a close examination of the larva and its burrow. In 
answer to a request for material and information on the 
species, Dr. Koningsberger has kindly sent me the specimens 
which I now have pleasure in exhibiting to this Society. Dr. 
Koningsberger tells me that the larva feeds on the ants and 
aphides that crawl over the coffee-twigs ; pupation takes place 
in the burrow ; oviposition has not been witnessed, nor have 
any but full-grown, or nearly full-grown, larve been found, so 
that it is not known if the burrow is enlarged to allow of the 
increase in size of its occupant, or if it is originally made large 
enough to accommodate the larva throughout its life. A 
figure of the larva is published in the above-mentioned work 
(Fig. 59), but it is evidently only a copy of the figure of a 
Cicindelid larva in Packard’s “ Guide to the Study of Insects,” 
and is quite inadequate. The Collyris larva differs from the 
larvee of the British Cicindelx by its flattened femora, small 
size and more cylindrical body ; the tubercles of the fifth 
abdominal segment bear a comb of three or four short teeth 
instead of one long hook, and these combs are better adapted for 
getting a purchase on the walls of a wooden burrow than 
would be the long hooks of some sand-burrowing Cicindele. 
I intend to make a careful and critical study of the mouth- 
parts; as it is certainly unusual to find a predaceous larva 
with mouth-parts qualified to excavate burrows in wood. The 
mouth of the burrow is countersunk, and Mr. A. H. Hamm 
informs me that the same feature can be seen in the sand- 
burrows of the British Cicindele. I have no doubt but that 
the lower surface of the head of the Collyris larva fills com- 
pletely the orifice of the burrow when the insect is awaiting 
its prey, the jaws projecting into the countersunk area. The 
adult Collyris emarginatus is arboreal in its habits, is remark- 
ably fleet, and readily takes to wing; in Borneo, as I have 
shown (P. Z.8., 1902, vol. ii, p. 264), it is mimicked by a 
flower-haunting fly of the genus Sepedon; it feeds on small 
insects, and the statement in the Deutsche Entomol. Zeitschr.
