I have given as a sub-genus a, remarkable insect 

 in my Collection, which accords with none of the 

 genera which have already been described ; it is 

 evidently a Sepidium, and approaches Oxura and 

 Trachynotus in some points, and yet differs en- 

 tirely in the shape of the thorax with any species of 

 Sepidium yet published. I name it therefore, Trache- 

 loeum, from the Greek TpaXrjXaios, its chief characters 

 being derived from the anomalous form of the thorax 

 which in the major part of the above genera, may 

 be regarded as hexagonal ; in the present instance, 

 it is quadrilateral, the anterior angles being rounded. 

 The following differences at once distinguish it from 

 other genera belonging to this family. 



Thorax fere quadratus angulis anticis rotundatis, 

 posticis gradatim minoribus. Corpus valde con- 

 vexum. Elytra fortissime sulcata, sutura et lineis 

 ternis elevatis conspicua, lineis neque basin nee api- 

 cem attingentibus. Corpus infra contractum, elytris 

 abdomen ambientibus, lateribus fortiter sulcatis, in 

 reliquis Trachynoto convenit.
