inner side covered with liner ones; the firsl joint fringed with 

 short, still' hairs on outer side only; the galea truncate at the tip, 

 Avhich is densely fringed with tine hairs, inner margin with fe\\er 

 sioni hairs, and the inner distal angle hearing a few stout spines; 

 the labium \\ilh three-jointed palpi, the large ovate galeae with 

 their lips projecting a little In-yond the tips of the small lanceo- 

 late laciniae, both galeae and laciniae pilose. 



Thorax depressed, widest across prothorax where the pronotnin 

 is continued laterally into a wide, thin margin, each margin end- 

 ing anteriorally with a prominent acute process. The wing pads 

 reach to about the base of the third abdominal segment. The 

 legs are rather long, the foreleg being the longest; the fore 

 femora stand almost at right angles to the long axis of the body, 

 the middle femora at about 4." . and the hind femora closely ap- 

 pressed and nearly parallel with the bod \ ; the fore femur bears 

 three or four rows of short ^pines on its anterior side, and a few 

 stout hairs on its posterior side near the distal extremity; the 

 fore tibia is long, and iis inner side, as well as that of the 

 tarsus, bears a fringe of long hairs; the former bears at its inner 

 apical extremity a long, pointed process closely a p pressed against 

 the inner side of the base of the tarsus; the inner sides of the 

 fore tibia and tarsus both In-ar a number of small, sharp spines, 

 being the most prominent on the tarsus and the apical process of 

 the tibia. 



Abdomen long and gradually tapering from about the third 

 segment, tenth segment about as long as wide. (Jills present on 

 segments 1-7. each gill inserted on a lateral prominence bearing 

 a minute tooth just in front of the gill base, the lateral promi- 

 nence located just in front of the lateral, hinder angle of the 

 segment, directed outward at an angle of about 45 to the long 

 axis of the body; the first pair of gills small, single and spatu- 

 late, with minute fringes, are curved upward against the body 

 and are nearly concealed beneath the edges of the wing pads; the 

 other gills are double and shaped somewhat like a tuning-fork, 

 the two branches linear acuminate, about equal in length, the 

 outer branch bearing a. rounded prominence at its basal end at 

 the outer side; the respiratory filaments long, linear, about one 

 third the length the gill lamina. 



Setae about half the length of the body, plumose throughout 

 the greater part of their length, and then tail-pointed, the median 

 seta not so stout at the base as the others. 



'Colors of the body chiefly brOwn, amber on legs and thin mar- 

 gins of the body, an amber stripe along the dorsal median line 

 of the abdomen ; a brown band on each femur near the distal 

 extremity, and a small brown blotch near the base of each.
