St. Vincent examples, both male and female, have the head and 

 thorax blood-red.

f. 27, 6 . 



Hob. St. Vincent : windward side {H. H. Smith). 



Of four examples taken together by Mr. Smith one is fortu- 

 nately a male, exhibiting the prothoracic acuminate projections 

 just as in the type from Mexico. The front of the head is raised 

 into a laminar horn as in C. furcifer, but it is not bifurcate as in 

 that species, but only emarginate at the tip. 



Cebacis ttntcoenis, sp. n. 



Nigro-piceus, nitidus,peclihus testaceis, thorace elytrorum latiiudine, 

 fere glabra, elytris Icevihus. Long. 1 millim. 



Mas, capite cornu lamelliformi, thoracis longitudini cequali, apice 

 integro, armato. 



Teraina, capite prothoraceque mutlcis. 



Hah. St. Vincent (H. H. Smith). 



The distinguishing character of this little species is the long, 

 simple, lamelliform, and rather narrow horn which arises from the 

 front of the head in the male, similar to that in C. furcifer, but 

 longer and not bifurcate or emarginate at its tip. The head 

 is somewhat excavated between the eyes in the male, in the 

 female it is quite smooth aud convex. The thorax is as broad as 

 the elytra at the base ; convex and rather bulky, the sides have an 

 extremely fine reflexed margin. The mouth, antennae, palpi, aud 

 legs are testaceous. 



Four specimens, two males and two females, were obtained. 



Cebacis bifubcus, sp. n. (Plate XXVII. figs. 10, lOa.) 



Piceus, nitidus, fere glaber, protliorace valido transversa, elytrorum 

 latitudine. Long. 1 millim. 



Mas, capite jjrocessu laminato, tJioracis longitudine, utrinque 

 ante ocidos armato. 



Hah. St. Vincent, 6 {H. H. Smith). 



Under the microscope the thorax in this curious little insect is 

 minutely punctulate, and the elyti-a are obsoletely aud minutely 

 puncto-striate. The laminte which arise from the head are broad 

 and stout, inclined to each other, but projecting nearly straight, 

 curving only a very little inwards ; they arise from the inner side 

 of the eyes, and are as long as the thorax ; the apex of each is 

 simply rounded.

This peculiar genus has been placed by Lacordaire in the 

 Scolytides, where it stands in Gemm. and Har. Cat. next to
