Locality. Cuba. 



Body ovate, punctate on the dorsal surface with minute scattered 

 dots. 



Front of head bisinuate, the median point separating and extending 

 half the length of the first article of the first pair of antenna. 



The frontal lamina is rhomboid in shape. 



The eyes are large, oblong, posteriorly acuminate, and contiguous 

 along three series of ocelli. 



The first pair of antennae scarcely reach the posterior angle of the 

 first thoracic segment; with the peduncle 

 they extend to the fourth article, with the a 



flagellum to the tenth article of the second 

 pair of antennae; the flagellum is composed 

 of seven to eight articles, the first article 

 being very long, slender, equaling in 

 length the three following articles taken 

 together. 



The second pair of antennae extend to 

 the middle of the fifth epimeron; the fla- 

 gellum is composed of twenty -one articles. 



The first segment of the thorax is widely 

 emarginate anteriorly on its dorsal sur- 

 face; a great part of the dorsal surface of 

 the seventh segment is concealed. 



The epimera are rather wide; the pos- 

 terior angles of the posterior epimera are 

 somewhat acutely produced; the last 

 epimeron extends beyond the first segment of the abdomen. 



The prehensible legs are slender, smooth; the basis is rather nar- 

 row; the anterior ungulse are very small, the posterior ones somewhat 

 larger and more incurved. 



The ambulatory legs are rather long, robust, and furnished with 

 scattered spines. 



A large part of the first segment of the abdomen is concealed. 



The terminal segment is produced linguiform, smooth above; at the 

 base are two obscure depressions; the posterior margin is deeply 

 crenulate, terminating in the middle in seven teeth. The uropoda are 

 rather long; the inner branch is much longer and twice as wide as
