The first antennae are composed of seven articles, the two first ones 

 being almost fused; they extend just below the eye. The second 

 antennas are composed of nine articles and extend to the posterior 

 margin of the head. The basal articles of the first pair of antennae are 



b adjacent on the ven- 



tral side. The arti- 

 cles of both pairs of 

 antennae are greatly 

 dilated and flattened. 

 The maxillipeds have 

 a palp of two articles. 

 The palp of the man- 

 dibles is composed of 

 three articles, the ter- 

 minal one being very 

 slender and minute. 

 The second maxillae 

 terminate in two 

 lobes furnished with 

 small hooks. 



The first segment of the thorax is longer than any of the others, 

 being 6 mm. in length; the second and fifth segments are subequal, 

 each being 4 mm. 

 long; the third and 

 fourth are each 5 mm. 

 in length; the sixth 

 segment is 3 mm. 

 long ; the seventh is 2 

 mm. long. The ante- 

 rolateral angles of 

 the first segment are 

 narrow and acute and 

 are produced forward 

 to about the middle 

 of the head. The epi- 

 mera are distinctly 

 separated on all the 

 six following seg- 

 ments. They are nar- 

 row, elongated plates, not extending quite to the posterior margin 

 of the segments. 



The abdomen is deeply set in the thorax. The first segment has 

 the sides covered by the last thoracic segment. The four following 

 segments are as wide as the seventh thoracic segment or wider. The 

 sixth or terminal segment is trapezoidal, almost twice as wide as
