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. 



Fain. •]. CICINDELID.E. 



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 King (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- 

 delidce with long cylindrical bodies placed together. M. Latreille founds his primary division of 

 the CicindelidcB 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 

 " Coleopteres a" Europe 1 '' are founded, and nevertheless, avoids the glaring inconsistency of 



separating 



* Genus PLATYCHILE Nobis, Manticora Fab. 



AnteniuE cylindrical, articulo tertio secundo fere triplo longiore. 



Labrum transversum, medio antice bidentato. 



Mandibul<e exsertae, arcuatas, tridentatas, dentibus apice nigris. 



Palpi maxillares articulo ultimo obconico crassiore praecedente breviore. 



Palpi labiates articulis duobus primis brevissimis, penultimo longo fere cylindrico, ultimo securiformi. 



Mentum emarginatum medio unidentatum. 

 Caput magnum planum. Thorax planus in medio canaliculars, angulo postico utrinque porrecto subspinoso. Abdomen 

 insecti dimidii longitudine, sessile, cordiforme, thorace latius, elytris supra convexis haud connatis tectum. Pedes ante- 

 riores, in maribus saltern, tarsorum articulis tribus primis dilatatis, quarto brevissimo processuque laterali, ultimo tenui 

 unguibus acutis. Tibice omnes apice spinosae. 

 PALLIDA. P. laivis tota pallida capite bipunctato elytris sub lente vaiiolosis : variolarum centro eminente. 



Manticora pallida? Fab. Syst. Eleuth. 1. p. 167. 



Habitat ad Caput bonae spei. Mus. Macleay. 



Obs. This curious insect connecting Manticora with Megacephala, only differs from the Manticora pallida of 

 Fabricius in not having connate elytra.
