Anisosticta, Duponchel. 

 A. strigata, Thunb., which represents the above genus in the Canadian 

 fauna, is a small ovate or somewhat elongate insect (.13 in.), black beneath 

 excepting the sides and tip of the abdomen, which, with the legs and 

 antennte, are yellow. Above, the head is yellow anteriorly, the thorax 

 yellow, with two triangular black spots, the apices of the triangles being 

 applied to the base. These spots are sometimes irregularly v-shaped, or 

 the outer limb of the v may even be separated as a spot. Elytra yellowish, 

 with a common bilobed spot on the scutellar region, and usually eight 

 others on each, black ; these spots may, however, be confluent in a varying 

 degree, so as to form a less number of larger size.
