1. H^MATOPOTA 333 



at all dense, mainly black on the disc but with shorter more_ sloping pale 

 (usually grey but sometimes ferruginous) hairs on the hindmargins which can 

 rarely be said to form fringes ; sidemarginal pubescence long and outstanding 

 and usually all grey or brownish yellow along the actual margin, though 

 sometimes these fringes are more or less black. Belly ashy grey with the 

 sides at the base ranging from being very faintly ferruginous on the second 

 and third segments only to the sides on the three basal segments being all 

 conspicuously and extensively ferruginous ; pubescence rather short and 

 sloping on most of the disc but longer about the sides, and longer and more 

 tangled on the two basal segments, by no means sparse, and all pale grey 

 except for the numerous erect but curved bristly black hairs on the disc of 

 the seventh segment. Genitalia dark ferruginous with a two-jointed lamella 

 on each side, of which the basal joint is subquadrate and the second joint 

 half ovate, and these lamellae extend beyond the lower processes.^ 



Legs dull black and orange ; the orange colour forming broad rings just after 

 the base of the front tibial, at the middle knees, at two-fifths and four-fifths of 

 the middle tibige, on the basal two-thirds of the basal joint of the middle 

 tarsi, and on similar parts of the hind legs only more narrowly at the knees ; 

 the middle dark ring on the posterior tibice more or less brown and not 

 very sharply defined ; all the femora dusted grey ; front coxae long and 

 strong, obscurely greyish ferruginous or greyish black, and bearing long 

 pubescence which is yellowish on the basal half (or more) but black af terwai'ds 

 and shorter on the outside ; posterior coxre short and greyish and bearing rather 

 long mainly yellow pubescence. Pubescence behind the front femora long 

 and mainly dark colored, behind the middle femora nearly all yellow but 

 black about the tip, on the hind femora antero-ventrally long and almost all 

 yellow but denser and shorter all about the tip ; front tibias Avith inconspicuous 

 black dorsal ciliation though there are pale hairs on the orange part ;_ front 

 tibiae with a few " touch-hairs," and the front tarsi with numerous distinct 

 "touch-hairs" beneath and at the sides as well as long dorsal black hairs 

 at the tip of the basal joint and on the other joints ; middle tibiae with 

 numerous scattered long black hairs, and some shorter pale hairs on the pale 

 bands, spurs equal and black ; hind tibiae with a long conspicuous ratlier 

 dense black antero-dorsal fringe, and with a longer finer but almost equally 

 dense postero- ventral fringe, but with some pale hairs on the pale bands ; 

 basal joint of the hind tarsi with inconspicuous black pubescence. Pulvilli 

 brownish grey ; claws black. 



Wings (fig. 222) marmorated with hyaline spots or incomplete ocelli on a 

 muddy greyish or slightly yellowish ground colour, and these hyaline markings 

 (though varying) have a distinctive character whereby the species can almost

always be identified. A usually easy distinctive character for separating this 

 species from //. crassicornis lies in the discal cell, as in H. 2)h(viaUs that cell 

 includes two incomplete hyaline ocelli which are well separated by the dark 

 middle part of the cell, while in H. crassicornis those two ocelli are less 

 defined and meet in the middle of the cell so that they usually form a white 

 Y-shaped hyaline marking but this character must like all the wing-colour 

 characters be used with a wide allowance for variation ; the first posterior cell 

 has scarcely any regularly defined hyaline marking on its basal half; the 

 lower veinlet ending the discal cell is usually margined hyaline; there is 

 only one incomplete hyaline band just before the tip of the wing, and this is 

 continued as a hyaline margin all along the posterior margin of the wing
