wide ; relation of length of body to wing, i : i ; Sc pilose along basal 

 seventh ; Ri pilose along apical half, with some spines intermixed ; 

 R2+3 pilose except for small basal section ; Cu2 arcuate ; discal cell 

 absent. 



Legs : Leg i, length, 3.3 mm. ; coxa light brown ; trochanter brown ; 

 femur and tibia dark brown ; tarsus black. Leg 2, length, 2.9 mm. ; 

 coxa, trochanter, and femur brown ; tibia brown with small basal tan 

 ring ; basal half of basitarsus tan, the apical half black ; tarsal segments 

 2-5 black. Leg 3, length, 3.7 mm. ; coxa, trochanter, and femur dark 

 brown ; tibia dark brown with small basal tan ring ; basal three-fifths of 

 basitarsus and basal half of second segment tan, the remainder of 

 these segments, as well as all of segments 3-5, black; relation of basi- 

 tarsus to second segment, 5.1 : i ; calcipala well developed, reaching 

 the pedisulcus ; pedisulcus well formed one-third the distance from the 

 base of second segment ; claw long, the heel expanded, and with a long, 

 somev/hat curved, submedian tooth (pi. 35, fig. 248). 



Abdomen : Tergite of segment i dark brown, with short yellow 

 and black hairs ; pleurites dark brown, with long tan hairs that reach 

 the third segment. Segment 2 black, the anterior half white-pruinose. 

 Other segments completely black, segments 6-8 shiny. Segments 2-8 

 with short black hairs. Sternites tan. 



Genitalia: Cercus (pi. 33, fig. 208) dome-shaped, higher than 

 long (wide), the posterior angles well rounded. Anal lobe (pi. 33, 

 fig. 208) triangular in shape, the ventral area expanded, similar to 

 that of tricornis. Genital fork (pi. 33, fig. 210) very dark, with slight 

 basal dilatation; each apical expansion of genital fork like a wide 

 twisted ribbon, with a single toothlike extension near the midregion. 

 Ovipositor (pi. 33, fig. 209) small, like an equilateral triangle in 

 shape, the inner margin somewhat more heavily pigmented. 



Pupa (pi. 37, fig. 306, and pi. 39, fig. 346). — Very sparse granu- 

 losity, only in center of thorax ; approximately 6 very short simple 

 trichomes on either side of midline. Dorsal surface of abdominal seg- 

 ment : Without granulosity ; spines on segments 2-4 are anteriorly 

 directed, those on segments 7-9 are posteriorly directed ; segment 2 

 with 8 simple spines in transverse row across the middle, divided in 

 two by median space ; anterior to the outermost spine on either ex- 

 tremity of the row are 2 similar spines ; segments 3 and 4 with 8 

 simple spines in transverse row somewhat before the posterior margin, 

 with median separation ; segment 7 with 12 simple spines in transverse 

 row across the anterior margin, with median separation, and with 

 comblike groups of spines lateral to both extremities of the row ; seg- 

 ment 8 with 14 simple spines in uninterrupted row across the anterior
