l62 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 25 



Abdomen : Tergite of segment i tan, the anterior and posterior 

 margins white-pruinose, with yellow hairs; pleurites tan, with long 

 tan hairs that reach the third segment. Anterior half of segment 2 

 tan, the posterior half black, clothed with black hairs ; pleura white- 

 pruinose. Segments 3-6 yellow to light brown, with white pruinosity, 

 each segment with 3 black patches, one median and one on either 

 side; these segments clothed with short dark-brown hairs; segments 

 7 and 8 brown, without dark patches. Sternites tan. 



Genitalia: Cercus (pi. 30, fig. 163) dome-shaped, its height about 

 equal to the length (width). Anal lobe (pi. 30, fig. 163) broad except 

 for the ventral projection which is very long, narrow, and pointed. 

 Genital rod (pi. 30, fig. 165) with basal dilatation; apical expansions 

 of arms of genital fork narrowly triangular in shape ; the inner basal 

 angle is very large, shaped like a beak, hyaline ; the apical angle is 

 rather broadly pointed ; a short, well-sclerotized tooth extending from 

 the middle of the outer margin ; at times this tooth is absent, the apical 

 angle is very sharply pointed, and the distal half of the outer margin 

 is well sclerotized (pi. 30, fig. 165). Ovipositor (pi. 30, fig. 164) 

 short, appearing like a group of spikes within a membrane. 



Pupa (pi. 36, fig. 291, and pi. 39, fig. 331). — Granulosity on entire 

 thorax ; 5 bifid and 2 simple trichomes on either side of midline. 

 Dorsal surface of abdominal segments: No granulosity; spines on 

 segments 2-4 are anteriorly directed, those on segments 6-8 are 

 posteriorly directed ; segment 2 with 8 simple spines in transverse row 

 across the middle of the segment, the row divided in two by a median 

 space ; outermost spines very fine and hairlike ; anterior to the outer- 

 most spine on either extremity are 2 hairs, both very fine ; segments 3 

 and 4 with 8 simple spines in a transverse row across the middle of the 

 segment, divided by median space ; segment 6 with transverse row of 



6 spines across the anterior margin, with median space, and with 

 comblike groups of spines lateral to each end of the row; segment 7 

 with 20 simple spines in transverse row across the anterior margin, 

 with median separation, and with combs lateral to each end of the row ; 

 segment 8 with 13-29 simple spines in similar transverse row, with 

 combs lateral to each end of the row. Ventral surface of abdominal 

 segments : No granulosity ; all spines are anteriorly directed ; segment 

 4 with a single simple spine on either side of the midline at middle 

 of segment ; segment 5 with transverse row of 4 bifid or trifid spines, 

 somewhat before the posterior margin, with median separation ; seg- 

 ment 6 with transverse row before the posterior margin, composed of 

 4 spines, the outer two simple, the inner two trifid or bifid ; segment 



7 with transverse row somewhat before the posterior margin, the
