10 ANNULOSA JAVANICA. 
separating Clenostoma from the long-necked Cicindelide, as the first does; or of placing 
Ctenostoma near Therates, as in the second. It is acurious proof of the value of the table given 
in Hore Entomologice, pt. 1. p. 4, that an arrangement may thus be found, which will keep 
together the insects of asimilar formation of palpi, and which may nevertheless not be grounded 
on the consideration of these organs. 
The voracious insects which compose this family are all extremely active in their perfect state, 
and inhabit sandy districts, as it is in the sand that the artful and wary larvee dig cylindrical pit- 
falls for their prey. 
I shall now proceed to the description of such species of this most natural family as Dr. 
Horsfield collected in Java. They all belong to the three genera Colliwris, Therates, and Ci- 
cindela, and eight out of fourteen of them are quite new. ‘The length of their body, as well as 
that of the other insects described in this work, is always measured in inches or parts of an inch.
