General color dark reddish brown, not so deep a reddish cast as in 

 the former species. 



Head slightly more than one and one-third times as long as wide; 

 sides nearly straight ; five warts on each side from each of which there 

 arises a small spine, the posterior one the largest and stoutest; frons 

 projecting considerably between the basal segments of the antennae. 

 Eyes medium in size, not prominent, with small facets; one pair of 

 long, prominent, knobbed postocular spines. Ocelli large, distinct, 

 subapproximate, reddish yellow, with dark-red crescents, the anterior 

 one directed far forward. Mouth-cone long, sharply pointed, reaching 

 to the base of the prosternum. Antennae, slightly more than one and 

 one-half times as long as head; segment 3 about one and one-seventh 

 times as long as segments 1 and 2 together; segments 1 and 2 dark 

 reddish brown, remaining segments uniformly light brown, lighter at 

 the bases and apices, segment 3 lighter than any of the segments; 

 spines long, prominent, numerous; sense-cones not numerous except 

 on segment 2, where the sense area is large and conspicuous and the 

 sense-cones short and thick; several long sense-cones on segments 3, 

 4, and 5. 



Prothorax about one and two-thirds times as wide as long and about 

 five-sixths as long as the head, with long, dark-colored, knobbed spines 

 on the posterior and anterior angles and one pair midlaterall}^ ; also 

 one pair on the posterior margin just inside the pair on the posterior 

 angles. Fore coxse with a long knobbed spine on each coxa and also 

 armed with four short, very stout, 'pointed spines. Mesothorax as wide as 

 the prothorax at its anterior angles, abruptly tapering behind them. 

 Wings long and slender, transparent, extending to distal margin of the 

 fifth abdominal segment; three long knobbed hairs on the anterior 

 margin of the fore- wings near the base; a very light brown stripe in 

 the center of the posterior pair of wings extending slightly past the 

 middle. Legs long and stout, densely spinose; fore femora greatly 

 enlarged, one-half as wide as long. Fore legs evidently raptorial; 

 fore femora with two sharp, toothlike projections at the tip, within, 

 and a groove between them, evidently a sheath for the tibife; fore 

 tibiae with a small, anteriorly-directed tooth near the base within; 

 fore tarsi with an immense tooth on the inner side; fore femora and 

 fore tibiae each with a long spine underneath, all other spines very
