more elongate second article of the first antennae ; in having a prom- 

 inent spine at the distal extremity on the inner side of the third arti- 

 cle of the peduncle of the second antennae; in having the lateral 

 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 body furnished on the dorsal surface with spine- 

 like tubercles definitely arranged, and the head furnished with two

 four segments of the bod}^, 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 antennae, and in lacking the 

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

 ing a two- jointed flagellum to the first antennae instead of a three- 

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

 the second antennae, there being fourteen, instead of eighteen or 

 twenty.
