brown ; relation of basitarsus to second segment, 4.4 : i ; calcipala well 

 developed, reaching the pedisulcus ; pedisulcus well formed one-fourth 

 the distance from the base of second segment ; claw small, with almost 

 no heel and with no secondary tooth or spur (pi. 35, fig. 266). 



Abdomen : Tergite and pleurites of segment i reddish brown with 

 white pruinosity, the tergite with short yellow hairs, the pleurites with 

 long yellow hairs that extend back to the more posterior segments. 

 Segment 2 reddish brown, with white pruinosity and short yellow 

 hairs. Segments 3-6 yellow, each with a median dorsal dark-brown 

 patch and 2 similar patches on either side of the median one, giving 

 the appearance of 5 longitudinal rows of 4 patches each; the yellow 

 base color between the patches has white pruinosity ; segment 7 yellow, 

 with a single, less-pronounced patch on either side near the lateral 

 margin, the remainder of segment white-pruinose ; segment 8 com- 

 pletely covered by white pruinosity ; segments 3-8 invested with short 

 black hairs that are evenly distributed, longer on segments 7 and 8, 

 Sternites white-pruinose with black hairs. 



Genitalia : Cercus (pi. 30, fig. 160) somewhat higher than long 

 (wide), the posterior angles well rounded. Anal lobe (pi. 30, fig. 160) 

 high and narrow (short), about three times the height of the cercus; 

 ventral portion strongly tapered to a point, with a median projection 

 from the posterior margin that curves somewhat beneath the cercus. 

 Genital rod (pi. 30, fig. 162) with very slight oval dilatation; apical 

 expansions of arms of genital rod irregularly triangular in shape, 

 hyaline, the apical angle fairly sharp-pointed, the inner basal angle 

 very broad and protruding ; outer basal angle rather acute and small, 

 arising on the outer margin between the apical and inner basal angles. 

 Ovipositor (pi. 30, fig. 161) small, narrow, very short, the apex mem- 

 branous and somewhat expanded ; with riblike structures from base 

 along half the length. 



Pupa (pi. 36, fig. 290, and pi. 39, fig. 330). — Granulosity well 

 marked on central part of thorax ; 5 simple trichomes on either side of 

 midline, all but one close to the lateral margin. Dorsal surface of 

 abdominal segments : No granulosity ; spines on segments 2-4 are 

 anteriorly directed, those on segments 7 and 8 are posteriorly directed ; 

 segment 2 with 8 simple, hairlike spines in a transverse row about 

 three-fourths the distance from the anterior margin, the row divided 

 by a median space ; anterior to the outermost spine on either extremity 

 are 2 fine hairs; segments 3 and 4 each with a transverse row of 8 

 simple spines, each row divided in two by a median space, crossing the 

 segment somewhat before the posterior margin; segment 7 with 16 

 spines in a transverse row somewhat behind the anterior margin, with
