ANNULOSA JAVANICA. 15 



Palpi breves crassi articulo ultimo ovato apice subtruncato. 



Labium obconicum convexum setis terminalibus instructum. Paraglossce labio duplo lon- 



giores magna? rotundatae. 

 Mentum dente medio vix conspicuo. 



Caput haud thorace latius. Thorax convexiusculus truncatus obcordatus antice latior late- 

 ribus sinuatis. Elytra margine postico unidentato convexiuscula lateribus parallelis. 

 Obs. Mr. Kirby has published so excellent a description of this genus in the 14th vol. of the 

 Linnean Transactions, that the above generic character may appear superfluous ; and, indeed, it is 

 only here given for the purpose of comparing the species more readily with the following genus 

 Pericalus, to which they approach very near in affinity. Both genera have their elytra praemorso- 

 truucate at the posterior margin. 



22. Elegans. C. viridiaureus labro mandibulis palpis antennis pedibusque nigris, elytris sulcato-striatis siriit 



lateralibus punctatis latere aureo.

 Caput pone oculos nigros punctatum collo laevi. Thorax linea antica transversa curva aliaque media 



longitudinali fossulaque utrinque postica impressus. Scutellum nigrum. Elytra marginata lateribus 



aureis stria scutellari brevissima. Corpus subtus atronitidum. 



Obs. Fabricius takes no notice of the emargination at the apex of the elytra, which is a 

 character of the genus. The Carabus elegans of Olivier belongs to quite another genus. 



23. Quadrimaculatus. C. viridiaureus labro palpis antennisque piceis, pedibus rufis, elytris striatis ; maculis 



duabusjtavis.

 Obs. This last species differs in several important respects from Catascopus elegans, which 

 comes nearer to the species described by Mr. Kirby, and named by him C. Hardwickii. The 

 Carabus splendidulus of Fabricius, also belongs to the genus which thus contains four described 

 species. 



Subgenus PERICALUS Nobis. 



Antennae articulo tertio elongato. 



Labrum oblongum distinctum antice emarginatum. 



Mandibulae porrectse subparallelae. 



Palpi mandibulis vix longiores tenues cyliudrici. 



Mentum bidentatum medio piano truncate. 



Caput thorace latius collo distincto. Oculi globosi valde prominuli. Thorax depressiuseulus 

 obcordatus profundi canaliculars, antice emarginatus angulis subporrectis acutis, antice 

 latior lateribus sinuatis subreflexis. Elytra marginata postice unidentata. Abdomen 

 depressiusculum antice angustius.
