[214.] The Americvin differs a little from llie British sjiccirnens. In 

 the first place it is scarcely half the si/e, not only the mouth but the space 

 before and between the eyes is rufous, only the vertex and occijuit being 

 black : the black spot of the prothorax, instead of consisting of two 

 distinct spots connected only at their base, is only divided at its apex into 

 two lobe;,, and the spots of the elytra thougii similarly arranged, are less 

 distinct: they agree in having the body underneath, txcej4 the rufous 

 anus, black ; and the legs ruloub.
