 and extends a little beyond the end of the abdo- 

 men. Its outer edge is cren-

Another individual was found at Catalina Island, 

 California, by Dr. J. (i. Cooper. In this specimen the sixth thoracic

 antenna', composed of twelve articles, extend to 

 the posterior angle of the tirst thoracic segment. 

 The tirst segment of the thorax is one and a 

 half times longer than any of the other segments, 

 wliich are a])t)ut eiiual in length. The epimera, 

 which are distinctly marked, and roundly pro-
