288 BRITISH LEPIDOPTERA. 



usual glazed line, with smoother piece (broader inside) on each 

 side of it, with radiating wrinkles. The maxilla-case is nearly 

 5mm. long, with 4mm. free, but is very closely appressed to the 

 pupa so that it is straight and no light is seen between it and the 

 pupa. It has a deep median suture, the halves strongly wrinkled 

 transversely and the wrinkles minutely subwrinkled. The rest 

 of the maxillae and the legs are very minutely wrinkled or rather 

 with very flat tubercles, arranged as if they were the remains of 

 nearly obsolete fine wrinklings. The antennae are divided into 

 segments, each segment subdivided by one transverse and one 

 or two obliquely longitudinal impressed lines. The prothorax has 

 a longitudinal dorsal suture, and the well-marked wrinklings, though 

 irregular, have some tendency to be arranged concentrically to 

 the middle of each lateral half. The mesothorax has an indication 

 of an obsolete mediodorsal suture. There is the suture-like smoothness 

 at about the line of the inner edge of the patagia. The sculpture 

 inside these is transverse wrinkling, anastomosing and tending 

 to have a central focus in the median line, not far from the posterior 

 border of segment. The wing-bases are prominent with sculpture 

 that is rather irregularly tubercular than wrinkled but with no 

 definite tubercles or points. The wings are finely wrinkled, coarser, 

 and with a transverse arrangement basally, finer, and with longi- 

 tudinal lines more numerous, towards hind margin ; the nervures 

 can be made out, but not with facility ; Poulton's line is obvious 

 as a fine line, free from sculpture and with the margin beyond 

 (about o - 3mm. wide) with regular longitudinal lines ; it is also 

 visible on the slip of hindwing which, yielding to the 1st abdominal 

 spiracle (of 2nd segment), disappears opposite the 2nd. The 

 maxillae and wing-apices terminate very accurately at the margin 

 of the 4th segment. The metathorax is narrow, has two small 

 transverse ridges on each side of the middle line, and is elsewhere 

 wrinkled in a fairly regular pattern. The abdominal segments are 

 finely but boldly wrinkled. The 5th abdominal segment presents 

 dorsally, along its anterior margin, in the hollows of the wrinkles, 

 points that have some resemblance to pits. These become more definite 

 on the 6th and 7th, and are pits, pure and simple, on the 8th, though 

 wrinkling rather than pits still holds the posterior portion of that 

 segment ; 9 is entirely pitted. This transition from wrinkling to pitting, 

 passing backwards along the segments, is more advanced ventrally, 

 though even here wrinkling holds place towards the posterior 

 margin even of the 7th segment. Subsegmentation is not well 

 marked ; dorsally, a narrow anterior subsegment may be seen on 

 the 2nd abdominal and following segments, but the intersegmental 

 subsegment is in doubtful evidence even in the most favoured position 

 for detecting it, viz , behind the 3rd and 4th spiracles. In one or 

 two specimens, on the 2nd and 3rd abdominal segments, the dorsum 

 is divided into four tolerably equal subsegments, and, on the 3rd 

 segment, further subdivisions may sometimes be made out, as if into 

 5, the first and last being widest and the 4th perhaps even further 

 subdivided. In some specimens no subsegmentation can be seen. 

 The scars of prolegs vary a good deal, usually each is a slight 

 depression with a small smooth area as its posterior margin towards 

 which sculpturing radiates and dies out. In one specimen the whole
