This insect was forwarded to me, along with many other interesting 

 forms, by j\Ir. Belfrage, of Waco, Te.xas. Grote (loc. cit.) states that 

 it has the form of L. casta, Sanborn, (with which I am unacquainted, ) 

 " but is a smaller insect differing by the discolorous head."

The figure is copied from that given by Dr. Packard. This species 

 is much larger than L. cephalica, is much more slate colored beneath, 

 and the head is white instead of yellow. It is still rare in collections.
