HIPPOTION CELERIO. 125 



anteriorly than posteriorly, as if the wings and proboscis, in their 

 demand for greater length, had stretched it downward. The general 

 straightness of the pupa is preserved by a reverse state of the 5th 

 abdominal, which is longer ^dorsally, but with a resulting slight 

 S bend in the pupal axis. The other features of the pupa come 

 rather under the head of surface-sculpturing and -marking. The 

 sculpturing is not deeply impressed, and gives to the casual view 

 the idea of a smooth pupa ; the general character is that of trans- 

 verse wrinklings, nowhere having any approach to points, spicules, 

 or flanges of any sort, nor do the spaces between the wrinkles any- 

 where incline to be pits. The labrum is quite dorsal, rather square, 

 faintly divided into two portions. The headpiece has faint sutures 

 running up from angles of labrum, with glazed eye at its posterior 

 angles. The prothorax has a nearly transverse hindmargin, the 

 front is hollowed against the headpiece, slopes off to a sharp angle 

 against the spiracle, which has a thickened margin on the prothorax 

 and a still thicker one against the mesothorax ; no spiculation. 

 There is a somewhat smooth centre on each side of the prothorax, 

 from which wrinkles radiate ; the anterior margin has rather stronger 

 wrinkles, making it look thick and raised. The antenna-cases have 

 fine transverse lines corresponding with the segmentation, apparently 

 two ridges to a segment ; towards the end of the antenna the 

 segments seem marked by a fine line, and the ridges are formed 

 of rows of minute tubercles, with longitudinal dividing lines, marking 

 off shaft and pectinations (which the imago is without) ; more 

 basally, a central row of tubercles (one to a segment) consists of 

 very definite, though small, raised points. The colouring of the 

 appendages is, like the rest of the pupa, terra-cotta with black spots, 

 the latter variable, absent on the antennae, and distally on the legs 

 and proboscis ; basally they may be numerous or few, large or 

 small; they tend to aggregate into patches on the leg-bases and 

 adjacent portions of proboscis. The mesothorax has wrinkles 

 consisting of very small raised surfaces arranged transversely in 

 ridges, much broken up into islets, but not destroying the generally 

 transverse alignment. The quasi-suture, marking the wing-base, is 

 just discernible as a smoother band extending from middle of 

 lateral half of front line, to anterior projection of metathorax. Out- 

 side this are various smooth patches, ill-defined, one of which, with 

 a central elevation or two, seems to be the wing-spine area, 

 discoverable in many Sphingid pupae, but here, at first sight, quite 

 absent. The wings are extraordinarily well-marked. The nervures 

 are raised ridges along each of which is a row of black spots, more 

 marked costally and towards hindmargin than basally ; Poulton's 

 line at apex may have a dark line. The area of wing between the 

 nervures has very numerous fine longitudinal wrinkles, looking like 

 a rough woollen or silken surface well brushed down. Poulton's 

 line is very distinctly marked at the costal apex and along the 

 greater part of the hindmargin, there are no black spots beyond it, 

 and the "brushed down" wrinkles run across it with a definite 

 break. The eight nervures that reach the hind margin in the imago 

 are all extremely distinct, as well as ic, which is, however, without 

 black spots, the three more costal nervures cannot be individualised. 

 The metathorax is narrowed medially ; the surface is very smooth
