over a slight triangular impression in the front of the 

 mesosternum. Abdomen eomposcd of five segments, the 

 apical one not emarginate, the sutures straight. The legs 

 are very slender, the four anterior coxre are approximate ; 

 the tarsi are very long and slender; the 1st joint is very 

 long, the 2nd, 3rd and 4th become shorter, the 4th being 

 one-half the length of the 1st; the 5th is scarcely longer 

 than the 1st. Body above covered with fine scale-like 

 pubescence ; vmderside clothed with silky pubescence. 



The antennfe are unfortunately wanting in the INIuscum 

 specimen, but I am enabled, by the kindness of Mr. Jan- 

 son, to give the following from a specimen in his collection. 

 AntenujB reaching to the back of the thorax ; basal joint 

 elongate, reaching to the middle of the eye, the 2nd joint 

 very short, the 3rd nearly as long as the 1st; the following 

 joints scarcely shorter than the 3rd, subequal, nearly 

 cylindrical, but a little narrowed at their bases.

The thorax is at the base nearly straight next to the 

 scutellum, but is broadly sinuate on each side, so that at 

 first sight it appears only bisinuate. Epipleural fold of 

 the elytra is broad at the base, gradually narrowing to the 

 apex, channelled posteriorly.
