and the front narrow, as in the L. Qaudichaudii. The antennae and 

 stylets are shorter, and the extremity of the flagellum was not sca- 

 brous, or scarcely so ; the last joint is about as long as the preceding. 

 The granulation of the surface is also much more distinct than in the 

 Gaudicliaudii. 



Lygia cursor. 



Antennae cephdlotlioracis longitudine, flagello 21-articulato [in specimine 

 scrutato post 14 articulos constricto deinde articulis septem brevioribus 

 confecto] versus apicem sells latitudlnis articulo longitudine scepeque 

 setuld utrinque armatis. Abdomen parce longius quam latum, thorace 

 subito paxdo angustius, segmento postico apice triangulate, angulis 

 posticis breviter acutis. 



Antennae as long as the cephalothorax, flagellum twenty-one-jointed 

 [in the specimen examined, after the fourteenth joint, a constriction 

 and then seven smaller joints]; surface of the joints towards extre- 

 mity bearing many setae, which are as long as the diameter of the 

 joints, and have often a setule on either side. Abdomen sparingly 

 longer than its breadth, abruptly a little narrower than thorax; 

 last segment triangulate at apex, the posterior angles short acute.

Length of body, exclusive of stylets, ten lines. The stylets were 

 not present in our specimen. The last joint of the flagellum is much 

 longer than the preceding, and as in other species, has a tuft of setules 

 or very short hairs at apex, as seen when magnified. The constriction 

 in the flagellum appears to separate the extremity from the rest, and 

 as it occurs just seven joints from the extremity (one-third the whole 

 number), it may be a permanent characteristic of the species.
