126 BRITISH LEPIDOPTERA. 



and shining, the valleys between the wrinkles being wide and 

 shallow. The hindwings extend to the end of the 2nd abdominal 

 segment, slightly encroaching on the spiracle of that segment, yet 

 with a deep sinuation here as if the spiracle held it back, or as if 

 it desired to minimise its encroachment ; beyond the spiracle the 

 narrow slip has a median (Poulton's) line. The abdominal seg- 

 ments dorsally present sometimes merely the ordinary wrinkles, and 

 are otherwise very smooth and level ; in other specimens certain 

 deeper impressions on the anterior segments indicate subsegmenta- 

 tion, but rather indefinitely, nor can the intersegmental subsegment 

 be made out ; on a well marked dark specimen subsegmentation is 

 apparent on segments 5 and 6, usually these are quite smooth (apart 

 from the fine wrinkling) ; in this one also, a dorsal depression (as 

 in some Amorphids) can be traced, and is most marked at anterior 

 margins of abdominal segments 5, 6 and 7. The wrinkled waves are 

 small at the front of segment, and a little irregular (as by cross-waving 

 breaking them up into short portions) ; posteriorly and laterally they 

 run in definite transverse waved lines; in front of the spiracles their 

 crests are rather sharp, but there is no other trace of the special 

 development shown here in some Sphingid pupas ; the cicatrix 

 of horn is a small, shallow polished hollow. Ventrally the cicatrices 

 of prolegs on abdominal segments 5 and 6 are slight, shallow 

 depressions practically evanescent ; there is a pitted spot outside 

 this (the triple ventral tubercle ?) ; sometimes there is a slight 

 smoothness, or silky polish on the cicatrix, at other times it is 

 practically absent. There is a central ventral furrow along abdominal 

 segments 5, 6 and 7, marked by a black line ; the line is more persistent 

 than the groove, which may be wanting. The anal armature 

 is a spine rather longer than broad at its base, ending in a 

 more slender portion, which is smooth and polished and armed with 

 two sharp points, one diverging to either side at its extremity ; length 

 of spike 2mm., width at base i^mm., thickness at base imm. The 

 colouring of the abdominal segments is very variable ; the golden- 

 brown ground-colour may have little to modify it except the very 

 conspicuous black spiracles, a blackness that, in a dark specimen, 

 extends a little beyond the spiracles, but to nothing like the extent 

 observed in Daphnis nerii. The other dark markings of the abdomen 

 are dark spots ventrally, and, on one specimen, dark shading on 

 the flanks, as in some pupae of Hyles euphorbiae, looking very like 

 a reminiscence of the lateral stripes of Sphinx larvae. The anal 

 groove is much alike in both sexes ; its sides are a little tumid, 

 but the segment is conical with nothing of the special prominence 

 of the Amorphid pupa ; the wrinkling of abdominal segments 8, 

 9 and 10 is rather finer, but otherwise much the same as of the 

 other segments. The $ pupa has a circular mark on segment 9, 

 enclosing two eminences with a longitudinal depression between 

 them. The 2 pupa has a slight groove from the anal groove, 

 extending to the front of the 8th segment and on the 8th on the 

 groove two marks, similar to that of the S but less pronounced ; 

 as the demarcations of the segments are much obliterated here, 

 doubtless the posterior of these is on the 9th abdominal segment. 

 Another specimen is rather abnormal, it has the appearance of a 

 $ , but with a second pore just on the incision of 8-9 (which is
