capitulate club of the antennae. We frequently meet with small Coleoptera, both in 

 the Erotylidse and in the Endomychidse, with the tarsi apparently four-jointed and very 

 simple, i. e. neither expanded nor with bilobed joints. That these insects are of doubtful 

 location in the Clavicorn series is obvious, when it is considered that the relation 

 of many genera with such families as the Cryptophagidae and with genera such as 

 Fphistemus is not well ascertained. 



1. Brachylon breve. 



Oblongo-ovatum, nigro-piceum, nitidum ; antennis pedibusque flavis ; elytris singulis seriebus quinque 

 punctorum, postice obliterates. Long, vix 2 millim. 



Hab. Mexico, Omilteme in Guerrero 8000 feet (H. II. Smith) ; Nicaeagua, Chontales 

 (Janson). 



Broadly-oval, pitchy-black, the head, thorax, and the base and margins of the elytra 

 being of a pitchy-red, almost blood-red colour ; the antenna?, palpi, and legs are chestnut- 

 yellow. The whole insect is smooth and shining, without pubescence, and impunctate 

 (saving about seven series of rather sparsely disposed punctures on the elytra, which 

 terminate at about one-third from the apex). The head is small, received, but not 

 deeply, into the thorax, and when turned downwards forming a uniform outline with 

 its front. The antenna? are short, with a capitulate club, apparently consisting of three 

 closely soldered joints. The eyes are small and very slightly prominent. The palpi are 

 very little developed, and cannot easily be observed ; they are light yellow, and appear 

 to have a small securiform apical joint. The thorax (with the head) is quite smooth ; 

 its sides are very finely margined ; the front angles are depressed, so that the small 

 opening for the head is not much cut out, but would appear semicircular viewed from 

 the front. The elytra are of the same width as the thorax at the base, and closely fitted 

 to its bisinuate hind margin; they are smooth, with the exception of the punctate 

 stria?. In some examples the whole insect is nearly black,, with yellow legs and 

 trophi. 



Five examples, all apparently referable to one species.
