1. H^MATOPOTA 343 



numerous beneath tlie front tarsi ; spurs blackish. Pubescence on the front 

 tibite forming ratlier long but not conspicuous black ciliations above and 

 behind on the basal two-thirds ; on the middle tibise long not dense 

 mainly pale haired ciliations above and behind, and a shorter black ciliation 

 beneath on the middle quarter ; on the hind tibiae the usual dense black 

 antero-dorsal fringe and a long dense softer postero-ventral ciliation, and on 

 the pale bands some ,pale hairs in both these fringes. 



Wings more like those of 11. pluvialh than of //. crassicornis but with the 

 dark coloring more washed out, and without the muddy yellowish tinge of 

 II. 2)l'tivialis or the dark marbling of H crassicornis, and the hyaline markings 

 may be broader and perhaps less defined than in either of those two, and 

 there is no trace of any hyaline markings along the absolute hindmargin of 

 the ^ving. Squamae paler glassy yellowish brown and with yellower margins. 

 Halteres whitish, with the basal half of the knob blackish on the upper and 

 under sides. 



Very much like the male. Frons yellowish grey or sometimes blackish grey, 

 quite one-third the width of the flattened head, and almost parallel-sided ; the 

 shining black callus hardly looped on the upper margin ; the dull black 

 spots rather rounded, and the middle spot sometimes more distinct than 

 usual j pubescence on the frons longer, denser, stronger, more erect, and blacker 

 than m //. plvvialis, though there may be some short pale inconspicuous 

 pubescence in very perfect specimens and there is some longer but com- 

 paratively inconspicuous pale pubescence just below the dull black spots. 

 Face whitish grey, with the black dots on the upper part of the side- cheeks 

 small and not at all crowded ; epistoiua whitish, but with the usual four 

 small black spots ; pubescence of the face, side-cheeks, jowls, etc., white or 

 yellowish white ; postocular rim greyish _ yellow _ or greyish white with a 

 short dense rather brownish yellow ciliation behind and sometimes on the 

 upper third an anterior sparse row of slightly longer black bristly hairs ; this 

 brownish yellow cUiation grows slightly longer near the upper eye-angles, 

 but is sparse behind the vertex, and there are a few longer curved thin black 

 hairs on the back part of the vertex between the eyes. Palpi dull greyish 

 yellow, bearing numerous but not at all crowded black bristles on the out- 

 side of the second joint almost to the base, with a few short pale ones inter- 

 mixed on the basal half and some long thua whitish pubescence beneath near 

 the base. Eyes longer than deep, flatter above than below, and bearing 

 short inconspicuous pubescence ; in life the eyes are plain brown with black 

 zig-zag bands, the two lower bands being similar to those of //. pluvialis and 

 the interrupted middle band rather similar but the round middle spot larger 

 and connected by a very narrow line to a much smaller spot, though the 

 third spot is almost as large, the second band from the top is thinner and 

 more sharply angled the angle which is dipped towards the connecting part 

 of the middle line being very deep, and on the hindmai-gin this band is more 

 connected Avith the top one, and the top band with one sharp angle extending 

 into the gap in the dip of the next band ; it must be noted that this comparison 

 with the eye of II. phivialis is only that of one individual specimen against 

 another and therefore may not always hold good ; in another specimen the 

 eyes — reversing the bands — were noted as rich chocolate brown with four green 

 zig-zag bands, of which the top one had one 

 deep dentation near the frons and a smaller 

 one still nearer, while the second band had 

 loojis to allow for the dentations of the upper ^ 



band and was connected with the third ^"' i\VK\$A'^''^~ 

 band, and the third band had two upward „ „„. ^ ,„„„,„ .■,„;,„„ o v m

dentations towards the loops in the second 



band, while the fourth band was only undulated. Antennte (fig. 225) _ one 

 and a half times to more commonly twice as long as the head ; basal joint 

 usually only a little shorter than the third joint, about four (sometimes only 

 two and a half) times as long as broad, and not in the slightest degree ovate 

 though rather compressed about the base, and usually with a constricted ring 

 near the tip ; this basal joint is entirely dulled even to the absolute tip with 

 light grey dust, and bears the usual black dorsal and lateral bristly hairs but
