f)2 MISCELLANEOUS PAPERS. 



yellow; 3 to 6 inclusive are yellow, with 5 and 6 shading to gray-brown 

 at tips; 7 and 8 brown. Dark-brown area on inner margin of seg- 

 ment 2 probably a sense area; simple sense cones on segments 3 to 8. 



FrotJiorax almost as long as head and about one-third wider than 

 long; it bears ten prominent spines, a pair on anterior margin, one on 

 each anterior angle, one midway on each side, and two on each posterior 

 angle. Sides of mesothorax almost parallel and united evenly with the 

 sides of the metathorax, which latter converge posteriorl3^ The /"wt" 

 coxx> are protruding and form wdiat appear to be the prominent sides 

 of the prothorax; each is tipped with a long spine. Fore femora 

 enlarged; fore tarsi each armed with a very small tooth. Wings reach- 

 ing nearly to base of tube, both pairs similar, clear white, with a long 

 simple fringe on both anterior and posterior margins. 



Abdomen about equal or slightly wider than the mesothorax; seg- 

 ments 2 to 7 inclusive taper uniforml}^, witli hind angles prominent. 

 Abdomen uniform brown with the thorax and head; red pigment con- 

 spicuous. Segments 1 to 7 each with two long spines on each side 

 near posterior margin, the outer ones in each case appearing as the 

 spine on the outer prominent angle; the spines approach each other 

 and the margin on segments 7, 8, and 9 to form a pair on the promi- 

 nent angles. Segments 1 to 7 have each two pairs of strong, incurved 

 spines at about one-fourth the width of the abdomen from the margin 

 and in each case the hinder pair is the stouter; these spines function in 

 holding the wings when at rest. Tip of tube bears six long spines 

 about as long as the tube itself, and several shortier ones. Scales 

 present on last segments of females. 



Males are similar to females in most respects, but possess the very 

 greatly enlarged fore femora and do not have scales on the last abdomi- 

 nal segments. 



Described from, one female and two males.
