Lontjicornia Malayana. 595 



longei' than broad^ the sides with curved striolse more or 

 less directed towards the centre ; scutellum curvilinearly 

 triangular^ glossy green^ impunctate, the sides purple ; 

 elytra dai'k blackish-blue, each with a pale brassy-green 

 rather narrow stripe, the whole with a slight purple tinge 

 and varying according to the light ; body beneath green- 

 ish varying to blue, with a short silky white pubescence ; 

 legs chalybeate, tarsi darker, all the femora at the base 

 bright I'eddish-fulvous ; antennae chalybeate-blue. 



Length 9 lines. 



This is the only species known to me which has all the 

 femora chalybeate with their bases red, each colour being 

 distinctly limited. 



Leontium. 



Leontium, J. Thomson, Syst. Ceramb. p. 175; Lacordaire, 

 Gen. ix. 19. 



Caput a,ntice angustatum et paulo productum. Mandi- 

 ftitte elongatae. Antennae (c?) corpore vix longiores, 

 filiformes, articulo tertio quarto longiore, ultimo 

 prsecedenti subsequali. Caetera ut in Ghloridolo. 



The comparative shortness of the antennae, and the 

 greater length of the third joint, give the males, at least, 

 of this genus a somewhat different style to those of 

 Chloridolum. Another character, which seems tolerably 

 constant, is the narrowness of the head beyond the eyes, 

 and the consequent approximation of the mandibles at 

 the base ; this confers a lengthened outline on the muzzle 

 which is not manifest in the other genus. M. Lacordaire 

 divides Leontium into two sections: — (1) Joints of an- 

 tennae from 5-10 shortly spined, &c.: — (2) Joints 5-10 

 angulate at the apex within, &c. There is one species 

 of each section in the collection. 



Leontium punctigerum,. 



L. angustum, viride; pedibus quatuor posticis cyaneis; 

 prothorace utrinque obtuse tuberculato, supra cre- 

 berrime punctato; articulis antennarum 5-10 apice 

 spinosulis.
