Male. Palpi exceeding the proboscis by nearly the length of the last joint, 

 last two joints slightly enlarged ; vestiture brownish-black, a broad white ring at 

 middle of long joint and small spots at bases of last two; end of long joint, and 

 the last two joints with long black hairs. Antenna? plumose, the last two joints 

 long and setose, the others short, the thickened rings at insertions of hair-whorls 

 black, the rest pale; hairs long and black. Coloration similar to the female. 

 Abdomen densely hairy laterally, the basal white bands very broad. Eight and 

 left fore tarsi alike, black with narrow white rings at base and apex of first joint 

 and base of second ; right mid tarsus black with white rings at base and apex of 

 first and second joints; left mid tarsus without white ring at apex of second 

 joint; right hind tarsus white, a black band in the middle of second and third 

 joints, the last two missing ; left hind tarsus with a black spot on second joint, 

 the last three missing. Wings narrower than in the female, the stems of the

Obiginai, Description of Grabhamia nigromaculis : 



$. Head very dark brown, almost black, covered with ochraceous broad curved 

 scales on the vertex and occiput, a triangular spot of slender golden brown curved 

 scales immediately laterad, followed by flat, white, then brown, lateral scales and 

 light scales towards the ventral surface; white bristles and very slender, long scales 

 projecting forward between the eyes, a heavy bunch of pale forked scales in the 

 nape; antennae dark brown, verticels very dark brown and sparse, pubescence 

 white, basal joint very dark brown with flat scales; palpi very dark brown; proboscis 

 very dark brown with a tiny white spot (sometimes an indistinct white band) on 

 the apical part of the proximal third of its length, a few white scales at the base, apex 

 dark; eyes dark blue, red iridescence; clypeus very dark. 



Thorax almost black; prothoracic lobes covered with long rather slender spatulate 

 white scales and light bristles; mesothorax with a median third of slender curved 

 golden brown scales, pale on the curved half, and the outer thirds with rather 

 broader pale ochraceous scales; a bunch of pale bristles over the wing joint and a 

 few dark ones near the "bare space; " scutellum very dark (black) with pale 

 ochraceous slender curved scales and pale bristles; pleura very dark brown with 

 white spindle shaped and long flat scales, and pale bristles; metanotum very dark 

 brown. 



Abdomen very dark, covered with very dark brown, practically black, and pale 

 ochraceous scales, i. e., pale basal and very narrow apical bands, a median ochraceous 

 stripe on most of the segments, white lateral spots and a few pale scales scattered 

 in the dark submedian spots; the dark spots on the apical segments are much re- 

 duced so that these segments are mostly pale scaled. "Venter mostly pale scaled. 



Legs: Coxae and trochanters dark, covered mostly with white scales, a few very 

 dark ones and some dark bristles; femora ventrally light, dorsally speckled nearly 

 evenly black and white, light towards the base, and almost black just proximal to 

 the tiny apical light spot which very slightly includes both sides of the joint; tibiae 

 much as femora, more distinctly dark towards the apex; metatarsi speckled, darker 

 than the tibiae, and having a basal white band, very narrow in the fore leg; all the 

 tarsal joints are dark and in the fore and mid legs the first and second tarsal joints 

 have tiny basal white spots; in the hind legs all the tarsal joints are basally white 

 banded, the band on the fourth joint very narrow. Ungues large and equal, both 

 uniserrate. 



Wings clear with dark brown and white scales, speckled; the ventral scales all 

 white. First, submarginal cell a little longer than, and about half the width of the 

 second posterior cell; mid and supernumerary cross veins meet and are about equal,
