[October 
heavy veins light brown, light veins darker brown. Front 
slightly more than twice as high as broad. Four proclinate 
bristles of nearly equal size; upper pair occupying one-third the 
width of the front, lower pair one-sixth; inner bristle of next 
row near the eye-margin and well above the post-antennals, 
inner bristle very close to the eye and but little below the middle 
of the front; upper row with the lateral bristle very close to the 
eye, the inner bristle considerably higher, all bristles equi- 
distant; ocellar row of four strong bristles. Ocellar tubercle 
and median frontal groove distinct; vertex slightly elevated, 
sharp above. Front covered with sparse, rather strong seti- 
gerous punctures. Antennae small, nearly round, well retracted 
within their cavities; arista bare, as long as the eye; palpi 
small, with rather short bristles. Postocular cilia strong, larger 
near the middle of the eye; cheek with two stout bristles and a 
series of smaller ones between these and the antennae. Meso- 
notum subshining, clothed with minute silky black hairs; two 
widely separated dorsocentral bristles with several long black 
hairs between them. Scutellum large, semicircular, with two 
very strong marginal bristles and a weak hair at each corner. 
Propleura with three bristles near the coxa, three weaker ones 
above and a few hairs between. Mesopleura above hairy like 
the mesonotum, with one stout bristle almost as long as the eye 
at the louver hind angle of the hairy area. Sides of second seg- 
ment with a brush of stiff, bristly hairs; third segment with a 
few scattered black hairs behind, especially at the sides. Fourth 
segment soft and membranous, very pale; following darker, but 
still weakly chitinized; last segment narrow, tubular, black, with 
longitudinally striated chitinous covering. Legs rather stout, 
the hind pair especially so. Front tibiae with a single line of 
close-set setulae, their tarsi slender; middle tibia with a series 
of strong setulse on each side of the seam, the outer row absent, 
however, on the apical third; hind tibiae also with two rows, the 
inner one slightly stronger, with about ten bristles, and the 
outer one with only eight as it does not extend quite to the tip 
of the tibia. Hind metatarsus not noticeably thickened. Costa 
extending barely beyond the middle of the wing, not thickened, 
its cilia short and densely placed; first section one-fourth longer
