2. BOMBYLIUS 495 



black, leaving the apical eighth of the front, the apical third of the middle, 

 and the apical half of the hind femora, orange, though not very definitely 

 so on the posterior pairs ; extreme tip of the hind femora with a small 

 blackish spot in front ; last three joints of all the tarsi blackish ; coxse with 

 long dense tangled clumps of black hairs, and these hairs extending onwards 

 though less coarsely dense along two thirds of the under part of the front 

 femora and along more than half the middle femora, while the hind femora 

 bear a rather sparser longer black pubescence on about the basal half or more, 

 and the hind femora have in addition about six long black antero-ventral 

 stiffer bristly hairs on the apical half and a few rather shorter ones about 

 the tip above and in front ; all tibiae with rows of twelve to twenty small 

 moderately equal black spicules, there being three rows on the front pair 

 (front row depressed) and four on each of the posterior pairs ; front tibiai with 

 three small black spurs beneath, middle pair with about five luiequal spurs, 

 and the hind pair with a circlet of small spurs of which three on the under- 

 side are most distinct ; tarsi with numerous tiny black bristles, which become 

 very numerous on the soles ; tibiae and tarsi with some minute elongate 

 golden scales. Pul villi elongate ovate, almost as long as the claws, dirty 

 whitish ; empodimn only a minute spine ; claws black, rather long. 



Wings (fig. 291) brown (sometimes dark brown) all across the base 

 (including the alula), but the lower margin of this brown part sloping 

 steadily though irregularly upwards from the end of the alula to the middle 

 of the costal i)art of the marginal cell and leaving the rest of the wing 

 hyaline with numerous small brown spots ; six of these dots occur at the 

 tips of the veins (counting the two veins at the tip of the anal cell as one) 

 of which those at the tips of the radial and ui^jier branch of the cubital are 

 the largest, a seventh si)ot occurs on the discal cross-vein, an eighth near 

 the middle of the first posterior cell ( = closed cell above the discal cell), a 

 ninth at the base of the upper branch of the cubital fork, a tenth on the end 

 of the first veinlet issuing from the discal cell where it joins the lower branch 

 of the cubital fork, an eleventh on the end veinlet of the discal cell, a twelfth 

 on the basal part of the upper branch of the postical fork, and a thirteenth 

 at the lower angle of the discal cell ; there are hyaline kernels near each side 

 of the discal cross-vein and one at the end of the lower basal cell ; discal 

 cross-vein well before the middle of the discal cell ; the stout black basal part 

 of the costa bears numerous brownish golden scales behind and a few 

 above ; alulae large, with a minute brownish yellow fringe and with a 

 conspicuous fringe of pale golden hairs along the basal edge. Alar squamje 

 not small, blackish brown with a broad blackish margin of which the fringe 

 forms one of the conspicuous orange tufts mentioned as being visible on the 

 pleurai after the wing-base and below the alulae. Halteres small, light 

 brown, but difiicult to detect because so deeply imbedded in the long dense 

 pubescence. 



9. Extremely like the male. Frons at the vertex about one-third the width 

 of the head, reddish brown, steadily widening until well past the antennae 

 and the face there nearly half the width of the head ; the middle part of 

 frons bears dense reddish brown or pale brown pubescence which is short 

 when compared with the other pubescence (about a quarter as long as the 

 neighboring black hairs), but towards the sides numerous longer black hairs 

 are intermixed which are however still shorter than the other adjacent black 

 hairs but which merge into those on the upper part of the cheeks, and some- 

 times short glistening depressed pale yellow hairs occur near the sides when 

 level with the antenna} as in the male ; ocellar space with a tuft of much 

 longer outspreading black hairs, and near this towards the sides are other 

 black hairs which are not quite so long ; the reddish tawny pubescence on 

 the face extends (though only short) out to the eyes, and the longer dense and 

 almost whitish pubescence on the lower part of the jowls and behind 

 the mouth merges into similar pubescence on the lower part of the meso- 

 pleurK. Eyes longer in proportion, so that their front margin (in profile) 

 is nearly a semicircle. Antennas with the strap-shaped third joint a little 

 broader and contracting on the last third only. 



Thorax as in the male, but the pubescence on the lower part of the pleurae
