NO. 1310. NORTH AMERICAN TTrVSANOPTERA— HINDS'. 1 ^l 



and between these pairs, along- the liind edge of pronotuni. stands a 

 row of three smaller spines on each side. Metathorax one-third wider 

 than prothorax; nietanotal plate bears a few small spines. Wings 

 about one-fourteenth as broad as long, slightly colored with light 

 yellow; costal fringe of fore wings composed of short, stout bristles 

 intermixed with a row of shorter spines. Fore longitudinal vein bears 

 from ten to twelve spines arrang-ed in three groups, as follows: Two 

 groups upon the basal half of vein, the first of three or four spines, 

 the set'ond group of three, and beyond the middle of the wing four to 

 six spines scattered at considerable distances along the vein to its tip; 

 when onl}' four are present in last group the}' stand at nearly equal 

 distances apart; hind vein bears from fourteen to seventeen spines. 

 Occasionally one or two cross veins may be seen between the for(> vein 

 and the costal at about one and two-thirds its length, ])ut usually they 

 are not present; hind vein arises from fore vein at about the middle 

 of second group of spines. Hairs composing posterior fringes on })oth 

 wings are long, slender, wav}', and light colored. Legs concolorous 

 with bod}" or somewhat lighter, quite long- and slender; second seg- 

 ments of tarsi much longer than first; spines on inner side of hind 

 tibia' weak, except the pair at its extremity; legs sparcel}' clothed 

 with fine hairs. 



Abdomen as wide, or slightly wider, than the mesothorax, about 

 twice as long as wide; each dorsal plate of segments two to eight 

 marked near its anterior edge with a narrow, transverse line of dark 

 chestnut-brown color, widest at its middle and tapering gradually 

 toward the sides, disappearing at the upper edge of the groups of 

 three to five short spines which stand upon these segments just abo^'e 

 the pleural plates. Posterior edge of ninth segment bears a circlet of 

 eight long, stout spines, most prominent dorsally; terminal segment 

 bears six spines which are nearly as long as the preceding; besides 

 these long spines both of these segments bear a few finer spines. 



Redescribed from many specimens. 



Male. — "Head and abdomen yellowish white; thorax yellow. The 

 first two antennal segments white, the third at the end very weakly,
