with five brown marks along costal margin. 



Male: Length, 6.6 mm.; wing, 7.3 mm.; antennae, about 3 

 mm.; Middle leg, tibia, 6 mm.; tarsus, 6.1 mm.; Hind leg, 

 femur 6.8 mm.; tibia 7.5 mm.; tarsus 5.2 min. 



Head: Rostrum brown; palpi very dark brown, the last 

 segment very slender. Antennae (see fig. h), first segment 

 long cylindrical, second short, oval, about equal in size to the 

 swollen base of the first flagellar segment; segments 3-13 enlarged 

 at base into an oval knob, the inner side of this knob produced 

 into two long pectinations; on the third segment, the pectinations 

 a trifle over twice the length of the pedicel of the segment; pecti- 

 nations increasing in length to the 8th to 10th segments where the 

 pectinations are about three and one-half times as long as the 

 pedicel of the segment; from the 11th on gradually shortened to 

 the 13th; 14th segment simple, enlarged medially; there are 

 eleven pectinated segments, more than in maculata, bipectinata or 

 CO stalls; the pectinations are slender, tapering gradually to the 

 tip, which is not enlarged. Segments at the base with two long 

 hairs on the side opposite from the pectination, and the pectinate 

 arm is densely clothed with delicate pale hairs. Pedicels to the 

 flagellar segments rather long, subequal, conspicuously more 

 slender than the enlarged base. Segments brown on the knot 

 and pectinate arm, the pedicel conspicuously white. Front and 

 vertex extremely narrow between the eyes, practically divided 

 at the narrowest point ; front, vertex and occiput dark blackish- 

 gray. 



Thorax: Cervical sclerites brownish-yellow. Pronotum 

 brown on dorsum, more yellowish -brown on sides. Mes- 

 onotum, prsescutum, brownish-yellow with a broad rich reddish- 

 brown dorsal stripe on each side of the narrow ground middle line, 

 these diverging towards the suture; scutum dull yellow, very 

 pale, whitish, in the middle, most of the lobes reddish-brown, 

 these large spots being the caudal ends of the praescutual stripes; 

 scutellum very pale, whitish; postnotum yellowi.sh. Pleurae 

 Hght yellow, darkened on the ventral half; a broad, dark brown 

 stripe from the pronotum across the pleurae ending above the 

 metacoxae, where a less distinct band loms cephalad, traversing 

 the sides of the sternum, including the outer faces of the coxae. 

 Halteres, extreme base and most of the knob, light yellow, stem
