 margin of the first thoracic segment provided with two spines on 

 either side, the anterior one long and prominent; in having the first

 four segments of the bod} 7 , which are lacking elsewhere; in the prom- 

 inent spine at the distal extremity of the inner side of the third 

 article of the peduncle of the second antenna?, and in lacking the 

 " two- jointed " spine at the proximal end of this same article; in hav-

 jointed one; and in the fewer number of articles to the flagellum of 

 the second antenna 1 , there being fourteen, instead of eighteen or 

 twenty.
