ANNULOSA JAVANICA. 9 
In the further investigation of these families, which I shall now enter upon, I must regret my 
inability, for the present, to separate the genera from the subgenera with any certainty. 
Fam. ]. CICINDELID. 
Of this family I shall offer the following Synopsis Generum, both because the number of 
known genera is so small, and because MM. Latreille and Dejean seem to consider it almost im- 
possible to express by one tabular view the affinities which exist in the group. It must however 
be premised, that if we judge Cicindela campestris to be the type of the extensive genus Cicindela 
we find C. gracilis Pall. and C. coarctata Dej., leaving it for the genus Ctenostoma of Klug (Caris 
of Fischer), while by means of Euprosopus 4. notatus Lat. we approximate to Megacephala.

By recollecting the approximation of the extremities of this series, we have all the Cicin- 
delide with long cylindrical bodies placed together. M. Latreille founds his primary division of 
the Cicindelide on the comparative length of the penultimate joint of their palpi: a consideration 
so vague, that we can scarcely be surprised that he should, as he says, have found it impossible to 
arrange them according to their affinities. The above distribution of the family has, however, 
the advantage of combining all the considerations upon which the two arrangements given in the 
* Coleoptéres d’ Europe” are founded, and nevertheless, avoids the glaring inconsistency of 
separating

Fabricius in not having connate elytra.
