154 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I25 



Genitalia: Cercus (pi. 30, fig. 157) dome-shaped, the height 

 about equal to length (width). Anal lobe (pi. 30, fig. 157) rather 

 narrow, of about equal width (length) throughout, except at the 

 ventral portion where it becomes greatly narrowed to form a pointed 

 structure ; with slight projection on posterior margin that curves under 

 the cercus. Genital rod (pi. 30, fig. 159) with practically no basal 

 dilatation ; apical expansions of arms of genital fork triangular in 

 shape, the inner basal angle almost 90 degrees ; apical angle sharply 

 pointed, well sclerotized ; near the middle of the outer margin there 

 is a very short, sclerotized, toothlike projection, the margin also 

 sclerotized between the base of this projection and the apical angle. 

 Ovipositor (pi. 30, fig. 158) short, lanceolate, somewhat broadened 

 at apex. 



Pupa (pi. 36, fig. 289, and pi. 39, fig. 329). — Granulosity on entire 

 thorax; 5 bifid hairs on either side of midline. Dorsal surface of 

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

 anteriorly directed, those on segments 6-9 are posteriorly directed ; 

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

 its middle, the row divided in two by a median space ; anterior to the 

 outermost spine on either extremity are 2 hairs, the most anterior 

 somewhat heavier ; segments 3 and 4 each with a transverse row of 

 8 simple spines, crossing the segment somewhat before the posterior 

 margin, the row divided in two by a median space ; segments 6 and 7 

 with transverse row of 22 simple spines, with median separation, and 

 with comblike groups of minute spines lateral to each end of the row ; 

 segment 8 with uninterrupted row of 25-30 spines and with combs 

 lateral to each end of the row; segment 9 with 8 spines in uninter- 

 rupted row, without combs; all rows of spines on segments 6-9 are 

 across the anterior margins. Ventral surface of abdominal segments : 

 No granulosity ; all spines are anteriorly directed ; segment 4 with a 

 single simple spine on either side of midline near middle of segment ; 

 segment 5 with transverse row of 4 bifid spines, a little before the 

 posterior margin, with median separation; segments 6 and 7 with 

 transverse row of 4 spines about three-fourths the way back from the 

 anterior margin, the two outer spines simple, the two inner spines 

 either bifid or trifid ; the 2 spines on either side of the midline of seg- 

 ments 6 and 7 are more separated than those on segment 5, the dis- 

 tance between them approximately equal to that of the median space. 

 Terminal spines very small, pointed. 



Respiratory apparatus (pi. 36, fig. 289) of each side arising behind 

 the anterior margin of thorax ; composed of 8 filaments which branch 

 as follows : 3-3-2 ; all filaments very thin, with superficial annulations
