to be doing fairly well, they gradually died off, until there 

 were only a few that seemed likely to survive the winter. In 

 the spring of 1904 it was found that only four larvae gave 

 any promise of completing their metamorphoses, but two of 

 these ultimately disappeared. The other two formed cocoons 

 in due course, but only one imago emerged, and this was 

 unable to free itself properly from the pupal case. The 

 specimen therefore is imperfectly developed, and each 

 antenna is still encased in the pupal sheath. However, it is 

 evident that the offspring has inherited characters of each 

 parent, but in a modified form. The sixth spot of fore-wing 

 is present, but only faintly discernible. In the female parent 

 this spot is unusually large and united with spot 5, the 

 border of hind-wings is much broader than in filipcndulce, but 

 not so broad as in trifolii. Altogether the specimen closely 

 resembles the form of A. filipcndulce known as va.r. hippocrepedis." 



Mr. Edwards exhibited two males of the rare and beautiful 

 Papilio blumei, from the Celebes. The female was stated to 

 be excessively rare. 



Mr. Priske exhibited a specimen of Calosoma sycophanta, 

 picked up recently in Kew Gardens. It was dead when 

 found, but apparently had only just recently died as it was 

 not stiff. The species is only occasionally met with in this 

 country, and probably then only an accidental visitor. In 

 the South of France it is said to attack the larvae of the very 

 destructive processionary moth, Thaumetopcea (Cnethocampa) 

 processioned. 



Dr. Chapman exhibited a long series of Hastula (Dichelia) 

 hyerana, <$ and ? , and its dark var. marginata, a Tortnx 

 he had bred in long series from the South of France, to- 

 gether with details of the life-history. The exhibit included 

 (1) series of S > light and dark forms ; (2) series of ? , 

 light and dark forms ; (3) preserved larvae in each instar ; 

 (4) pupa cases showing dehiscence ; (5) stems of the food 

 plant Asphodelus microcarpus, showing the ravages of the 

 larva ; (6) a number of the only parasite of the larvae which 

 he had found, Xanthandrus comotus (a Syrphid fly) ; (7) a 

 number of microscopical details of the various instars ; (8) 

 photos of the ova masses; (9) photos of the plant in the open 

 showing the leaves tied together by the larva; (10) a series of 

 diagrams of the setae on various segments, the dehiscence of 

 the pupa and the cremastral hooks ; and (11) living larvae. 



He then read a paper on the exhibit entitled " The Life- 

 History of Hastula {Dichelia) hyerana " (see E. M. M., 1905, 

 pp. 100, 129, and 149).
