cms, seedpods (Aigner-Abafi), Sangnisorba seedheads (Szepligeti), 

 Onobrychis sativa (Bromilow), Lathyrus pratensis (Paux). 



Parasites. — Limneria sordida, Gr., and Mesochorus con fits us, 

 Hlmgrn. (W. H. B. Fletcher). 



Puparium. — On June 10th, 1906, on the Cotteswolds, at 800ft. 

 elevation, I discovered a newly-emerged imago of C. minimus resting 

 directly above its vacated pupa-case ; the latter was on a dried grass- 

 stem about *5in. from the earth and surrounded by the usual herbage 

 of the locality ; the head of the pupa pointed upwards, and there 

 appears to be a silken thread or its remains, indicating its mode of 

 attachment (C. J. Watkins). There is no indication of the mode of attach- 

 ment of Zeller's two pupae in the British Museum collection, but the 

 structure of the cremaster leaves one with a very strong impression that 

 it uses the well-formed hooks for suspension (Tutt). About the end of 

 August, 1872, about a dozen larvae prepared for hybernation, in confine- 

 ment, each spinning a silken webbing on the leno, and resting thereon ; 

 disturbance, however, caused the death of all the larvae but one, and 

 on June 3rd, 1873, this larva pupated, being neither suspended by the 

 tail, nor had it any silken cincture, and it might very well have been 

 passed over as a stony particle on the chalky soil of Portsdown Hill, 

 whence came the larvae (Buckler). 



Pupa. — The pupa is nearly 8mm. long, and 3mm. wide at the 

 mesothorax, almost straight on the venter, well domed on the dorsum, 

 with a distinct waist-like depression where the summit of the meso- 

 thorax falls to the metathorax ; the front is well rounded, with some 

 prominent and comparatively long hairs, the anal segments from the 

 7th abdominal turned round sharply to end at the cremaster, which is 

 in a line with the venter. The skin is greyish-white, almost trans- 

 parent, and thickly sprinkled with dark brown dots of varying size ; 

 the body (except the appendages and wings) with a plentiful supply of 

 longish, conspicuous hairs. Dorsally : the prothorax almost frontal ; 

 the mesothorax raised into a dome with a longitudinal, median, dark 

 brown ridge, the areas on either side to wing- bases speckled with small 

 red-brown dots, many of which coalesce into a blotch towards the front, 

 corresponding in series with those on the other segments, the shiny, 

 glossy (apparently spiculate) hairs abundant ; the metathorax curving 

 up in the front at either side into the mesothorax, narrow medially, 

 speckled with brown, a largish blotch at front upper corner on either 

 side, the dorsal ridge extending from the mesothorax over this segment, 

 the hindwing only traceable in a small area at base; the hairs frequent 

 as on other segments. The 1st abdominal segment short and narrow 7 , 

 apparently smooth, and w 7 ith fewer conspicuous hairs, a dark mark as 

 a continuation of the median line, and a very strongly-developed, 

 rounded blotch at each end laterally (against the wing-margin); the 

 1st, 2nd, 3rd, 4th, and 5th abdominal segments form first an ascending, 

 then a descending series in size, the 3rd being the largest ; on each is a 

 distinct, dark, lineated, mediodorsal mark, that would be a medio- 

 dorsal line, but that it is broken by the swollen subsegmental incisions ; 

 a conspicuous series of round dark spots on either side (subdorsally 

 and snpraspiracularly) one on each segment ; the hairs on large bases 

 are difficult to group as i, ii, and iii, which appear to be overshadowed 

 by the development of many secondary hairs ; the 6th, 7th, and 8th 

 abdominal segments decrease regularly in size, have the dark markings
