ASELLOTA OR ASKLLOIDEA. 



Family JANIRIDjE. 



Tole holmesi Richardson, new species. 



Body yellow in color, spotted with numerous brown dots. 



Head broader than long, with frontal margin almost straight, very slightly produced in the middle. 

 On either side, a little anterior to the middle of the lateral margin, is a process terminating in two 

 spines. The eyes are large, composite, and situated near the lateral margin, about halfway between the 

 posterior and anterior margins of the head. The first pair of antenna' extend to the end of the fourth 

 joint of the peduncle of the second pair; the basal joint of the peduncle is large, dilated; the two 

 following joints are slender; the flagellum consists of twenty joints. The second pair of antennae are 

 longer than the body. The first three joints are short, with an articulated exopod on tic third joint; 

 the fourth and fifth joints tin' very long, the fourth being slightly longer than the fifth; the flagellum 

 consists of numerous joints. 



The posterior portion of the lateral margin of the first segment of the thorax is produced on either 

 side into a triangular process; the epimeron is situated tit the anterior portion of the lateral margin and 

 is produced in a triangular process about as long as the posterior one. The antero- as well as the 

 [.ostein- lateral angles of the second and third segments are each produced in a long process, with the 

 bifurcate epimeron situated between them. The anterior portion only of the lateral margin of the fourth 

 segment is produced with the bifurcate epimeron situated at the posterior portion of the segment. 

 The fifth, sixth, and seventh segments have the anterior portion of the lateral margin produced in a
