522 BOMBYLID^ 



bottom of the eyes back to the niouthinargin fairly wide, dull orange-red or 

 yellow, and nearly bare ; the absolute underside of the head more blackish 

 and bearing only sparse microscoi)ical black pubescence ; lower part of the 

 Ijack of the head hardly puffed out and practically bare, but the hindmargin 

 of the eyes indented considerably about the middle so that the back of the 

 head is much wider there, and the upper part also widely arched out ; postocular 

 pubescence entirely composed of fairly abundant shimmering white closely 

 adpressed scaly hairs, but all the pubescence about the dee]> channel at the 

 top of the occiput is mainly black and more erect. Frons brownish black, 

 at its uppermost part fully one-eighth the width of the head, and continuing 

 so until about half-way down but then gradually widening in a slight curve 

 down to the antennie where it is nearly half the width of the head, and the 

 face very slightly widening after this ; frons (best seen when viewed from 

 behind and above) with rather long dense coarse black pubescence quite down 

 to and even past the antenniB. Proboscis large, with a long blackish base and 

 with large ribbed brownish orange sucker-fla})S, only the sucker-flaps being 

 extruded from the large mouth-opening ; paljii long and very thin, but not 

 half the length of the proboscis, brown or dull reddish orange, and also 

 mainly concealed in the mouth-opening bearing minute erect black pubescence. 

 Eyes quite bare ; facets all equal, but with the peculiar line at the middle of 

 the back part towards which the facets slope from both above and below 

 much less consjiicuous than m. A. Paniscus. Antennae oi'ange-red on the two 

 basal joints, 1)ut brown on the third joint and style ; basal joint more than 

 twice as long as deep, bearing numerous black l^ristly hairs both above and 

 Ijeneath ; second joint short and transverse, bearing some shorter black 

 bristles ; third joint forming an elongate cone which imperceptil)ly merges 

 into a long blunt apical style so that the two seem to form one elongate joint 

 which is longer than the two basal joints together ; third joint and its style 

 quite bare. 



Thorax black, with a rather short moderately dense erect thin blackish 

 pubescence on the disc, in front of which is a conspicuous broad dark tawny 

 collar composed of dense longer pubescence which extends all round the front 

 part of the thorax even to the underside ; numerous scattered whitish 

 scales occur on the disc which tend in very perfect specimens to form two 

 stripes which considerably widen out near the scutellum but which leave 

 all the depressed middle part near the scutellum clothed with only black 

 scales ; above each wing-base a patch of tawny scales occurs which is some- 

 what extended backwards ; postalar calli with some very long yellow bristles 

 pointing straight backwards, and above each wing-base is one long strong dark 

 orange bristle preceded by two or three similar but shorter bristles ; pleurae 

 with abundant, longer, and paler tawny pubescence, but with a large con- 

 si^icuous patch of dense white pubescence all about in front of and beneath 

 the wing-base though not extended at all away fi'om the oval patch, and all 

 the upper part of the metapleura^ with conspicuous glistening white coarse 

 pubescence ; pleurae on their under parts greyish black and almost bare. 

 Scutellum reddish brown, but black on the base and basal corners, and with 

 the erect thin black hairs extending all over just as on the thorax, but with 

 the i^ubescence at the sides white and rather long, and with pale scales all 

 over except on the middle, Avhile round the margin are about eight or ten 

 yellow or black long bristly hairs. 



Abdomen short oblong, moderately shining black ; second segment dis- 

 tinctly the longest, but the third slightly longer than the others ; second, 

 third, and fourth segments almost forming a square ; ground colour chestnut 

 on the sides of the second segment and also near the sides on the foremargin 

 of the third segment; second segment with an interrujjted narrow band of 

 cinnamon scales close against the foremargin ; third and fourth segments with 

 conspicuous interrupted bands of elongate white scales, of which the one on 

 the third segment occupies more than half the depth of the segment but does 

 not extend to the sides ; the white band on the fourth segment is similar 

 l)ut is extended to the sidemargins in the form of long white hairs and is more 

 widely interrupted in the middle ; the second segment has numerous black 

 scales all over except on the interrupted basal line of cinnamon scales and on 

 the middle, and also has dark cinnamon hairs on the chestnut part of the
