yellowish; elytra each with ten grooves extending near- 

 ly two-thirds the whole length from near the base ; ex- 

 terior margin yellowish, becoming obsolete at tip ; an 

 obsolete spot towards the extremity resembling the com- 

 mencement of a branch from the colour of the margin ; 

 feet pale rufous ; postpectus black, yellowish each side be- 

 hind and at the anterior angles ; venter black, with yellow 

 bands, terminating each side in triangles of the same co- 

 lour. 



Length one and one-tenth of an inch. 



This species is most closely allied to D. marginalis of 

 Europe ; the appearance of the superior surface of the body 

 is altogether the same, even to the form and appearance of 

 the frontal spot, nevertheless our insect is much smaller, 

 and the arrangement of colours beneath, on the postpectus 

 and venter, is altogether different. 



LACCOPHILUS, Leach. 



L. punctatus. Dusky testaceous : very regularly and pro- 

 foundly punctured.

Body suboval, short, dull testaceous ; head with two di- 

 lated slightly impressed spaces on the front ; clypeus ob- 

 tusely rounded at tip ; punctures numerous, rather sparse 

 on the vertex ; thorax blackish on the anterior and poste- 

 rior margins ; punctures subequidistant ; elytra darker than 

 the head and thorax, very regularly and beautifully punc- 

 tured ; punctures rather larger than those of the thorax, 

 subequidistant ; beneath, excepting the feet, also punctured. 



Length more than one-tenth of an inch. 



This is a very pretty species, readily distinguished from 

 others.
