project slightly ; and a bunch of setae above the procoxae ; femora 

 all with 3 rings of brown and long hair-like setae; tibiae with 3 

 dark rings each, the tarsi with darker tips and the claws entire ; 

 wing-cases extending to middle of abdominal segment 5 in 

 exuviae ; middle of 7 in alcoholics. 



Abdomen : broad and flat below, with the segments dark-banded, 

 and with lighter spots on the caudo-lateral angles of the segments 

 1-9; long lateral spines on 8 and 9, those on 9 reaching beyond 

 the tip of the superior anal appendage, and with long lateral setae ; 

 lateral keels also with setae on segments 5-7, the proximal seg- 

 ments nearly or entirely free ; spines on 8 and 9 black-tipped ; 

 anal appendages also black-tipped, the superior about one-third 

 shorter than the inferiors, and the lateral appendages about half 

 as long as inferiors ; superior appendage with setose lateral mar- 

 gins and a few setae near tip of its dorsum ; the inferiors, setose 

 on all surfaces but with larger setae on the lateral margins. 



Measurements: total length, 12-13 wirn- 5 length of abdomen, 

 8 mm. ; width of abdomen, 5 mm. ; length metathoracic wing- 

 cases, 4 mm. ; length median lobe, 3-4 mm. ; width median lobe, 

 3 mm. 



Described from one exuviae from which an adult male was 

 reared, several exuviae and one full-grown nymph. 



Adult, male. — Color dark brown, sometimes red and yellow. 



Head : buff to yellowish, labium and labrum yellow, clypeus 

 buff; front, vertex and occiput darker brown. 



Thorax : dark brown or buff frequently lighter on the sides and 

 below ; wings as in rubiciindulwn, and only slightly chlorinate 

 at the very base ; legs dark brown to buff ; tarsi brown, black 

 at tips ; claws brown, black at tips, the ventral teeth about half 

 as long as portion of claw beyond the tooth. 



Abdomen: brown or reddish (bright red in some), terga with 

 transverse median carina only on segments 2 and 3, the margins 

 above the lateral carinae somewhat darker ; genital hamule of 

 the second abdominal segment composed of two equal lobes, the 

 median pointed and black tipped, the lateral lobe rounded ; auricles 

 as long or longer than the hamules (Fig. 67, No. 5) ; superior 

 anal appendages, without large ventral tooth at middle, but with 

 a few smaller teeth, at about four-fifths the length of the appen- 

 dage from the base. 



Female. — Similar to male in nearly all points ; sternum of 

 segment 8 projecting ventrad for a distance about equal to one- 

 fourth of the vertical diameter of that segment, and forming a 

 part of the ovipositor. 



Measurements: total length, male 32, female 31 mm.; length 

 of abdomen, male 21, female 21 mm. ; length of hind wing, male 

 23, female 22-23 n^^- 5 width of hind wing, male 8, female 7 mm. 



Differs from riihicundnhiin in being generally lighter in color;
