COLEOPTERA FROM ECUADOR.

there are four costse, the first and third are only distinct posteriorly, 

 the second is very strong, shining, the fourth is finer and lateral ; 

 there is an ovate red spot just before the middle, and another some 

 distance from the apex. 



This species is most nearly allied to M. amazona, Baly ; but that 

 has three red spots on each elytron. 



35. Cephalodonta lycoides, n. sp. (Plate XXX. fig. 10.) 



C. nigra, opaca ; thoracis lateribus ochraeeis, fiexuosis ; elytris 

 postice bene explanatis, ad apicem longitudini latitudine cequali, 

 vitta obliqua humerali, fascia post medium suturaque ad apicem 

 ochraeeis. Long. 7 lin. 



Thorax slightly convex, rather rough above, trisinuate at the sides, 

 the anterior sinus the deepest, leaving the anterior angles projecting. 

 Elytra at the base one third broader than the thorax, gradually 

 widening to the apex, where their breadth equals their length ; the 

 sides rectilinear, the apex truncate and irregularly and obtusely 

 dentate ; each elytron has four costs, the first is fine and indistinct, 

 the second is well marked and shining, the third is only distinct over 

 the shoulder, the fourth is fine and only distinct towards the apex ; 

 there are two lines of very strong transverse punctures in each in- 

 terstice ; on the lateral expanded part there are some strong trans- 

 verse ridges, the apical portion strongly punctured. The underside 

 of the head, the middle of the sterna, and the middle of the abdomen 

 at its base and the lateral margins are yellow. The femora have a 

 yellow spot at the base.

Although this species has at first sight no resemblance to Cepha- 

 lodonta, I find no characters of suflScient importance to induce me 

 to separate it as a distinct genus. It has a strong resemblance to 

 some species of Lycidse of the genus Calopteron. 



I think that Alurnus cijaneus, De Breme (Ann. Soc. Ent. Fr. 

 1844, p. 312), a species omitted from Gemminger and Von Harold's 

 ' Catalogue of Coleoptera,' is better placed in Cephalodonta than in 

 dlurnns, and is closely allied to the species I have just described.
