HEMARIS FUCIFORMIS. 521 



minutely wrinkled (on 7 and 8 practically smooth), the intersegmental 

 subsegment, broader laterally and especially in front (on 7), but 

 disappearing suddenly on 5 and 6 at scars of prolegs. In front 

 of this is a narrow subsegment of brown (or yellow) colour, whose 

 rugae are quite independent of those of the last - described 

 (intersegmental) subsegment, but continuous with those in front ; 

 then a dark subsegment, broad dorsally, narrow laterally, and 

 including the spiracles, with some indication of a division into 

 two on 2nd and 3rd segments. In front of this is another subsegment, 

 not very definitely marked off on 1, 2, 3 and 4, except by colour; on 

 5, 6 and 7 it forms, dorsally and subdorsally, a slightly raised rib of red- 

 dish-brown colour, and some differentiation in the wrinkling laterally; 

 it is a little broader, reaching to close above the spiracles. Here 

 on 5 and 6 it has the sculpturing in the form of 5 or 6 transverse 

 wrinkles, rounded on 5 and rather sharp on 6, on 7 the area is 

 merely finely pitted, its margin above the spiracle, however, stands 

 up as a distinct ridge on 7, less so on 6, and hardly at all on 5 ; 

 in all, however, the subsegment slopes inward from this ridge to 

 the anterior border of the segment ; it is hardly visible except 

 when the pupa is bent. The intersegmental membrane is pale 

 reddish-brown, and its shagreening extremely fine. The proleg 

 scars on 5 and 6 are small, smooth areas, towards which the lines 

 of wrinkling radiate as they approach and then fade out ; some- 

 times they also present the aspect of raised areas with central 

 hollows ; a smooth area, sometimes raised, sometimes hollow, marks 

 the position of the larval horn. The anal spine is about 2mm. 

 long, i*6mm. broad at base, and about '9mm. thick. The margins 

 are slightly curved, otherwise it is roughly triangular. It ter- 

 minates in a fine spine, carrying two points, diverging laterally, 

 but somewhat dorsally. The specialisation of the anal spine in 

 these species (the genus ?) is shown in the clothing that it carries 

 of very fine spines on raised bases, and all pointing very nearly 

 directly backwards ; viewed dorsally, 10 are seen on each side 

 at tolerably regular intervals, with three or four more crowded, 

 but less typical, at the base ; they clothe also the whole dorsum 

 and half the basal aspect, and there is a small group on 

 each side of the segment ventrally at the base of the spine. 

 The anal scar is a rather deep cruciform hollow, whilst some concentric 

 striae mark the position of the claspers. The $ pore is quite 

 at the posterior border of the 9th segment, and has the usual 

 structure rather flattened down. The $ pore is quite at the 

 posterior border of 8, with 9 presenting a slight central suture. 

 There is practically no invasion of the area of 8 by 9, and at 

 first one takes the ? pupa for a $ , till the very different position 

 of the <? pore is compared with it. In one specimen the whole 

 of this region is very smooth ; it is judged to be a $ from a slight 

 invasion of 8, with a doubtful appearance of a pore there. In a 

 good light, with a strong glass, a considerable number of fine 

 hairs may be seen on the dorsum of the head and of the 1st and 2nd 

 thoracic segments (Chapman). The pupa is 24mm. long, cylindrical, 

 stout across the wing-cases, tapering to the head, which is conically 

 rounded ; the abdomen tapers off considerably to the tail, which 

 has a flat, triangular, sharpish spike. The pupa-skin is granulated,
