from its effects and died soon afterwards. The Brachycertis 

 has now been in the concentration camp of my greenhouse for 

 about two months ; has apparently eaten nothing during that 

 time ; has periods of apparent hfelessness, and subsequent fits of 

 great activity, as was seen at the British Museum yesterday." 

 Mr. Distant remarked that the genus Aathla extends to the 

 Southern Paliiearctic region, and there seems little doubt that 

 these species could be easily acclimatized there. All they 

 require at home is the run of a good palm or orchid-house, 

 but whether they wovild be a horticultural blessing is of 

 course doubtful. 



Mr. R. Adkin exhibited a series of Acidalia aversata. The 

 parent moth (a banded female, the male parent not being 

 known) was taken at Lewisham in June 1900. Of the result- 

 ing larvfe about one half fed-up rapidly, and produced imagines 

 in the autumn of the same year — a very unusual circumstance 

 in the habits of the species ; the remainder hybernated and 

 produced imagines in June of the following year, thus occupy- 

 ing the normal time in completing their metamorphoses. The 

 proportion of individuals following the female parent in the 

 two portions of the brood was almost equal, the percentages 

 being approximately 5.3 banded in the autumnal emergence as 

 against 58 in the spring, but in point of sex the disparity was 

 great, over 65% of the autumn moths being males as against 

 fully 72% females in the spring portion. 



Mr. G. C. Champion exhibited long series of Leptura 

 stragidata, Germ., and Strangalia jmbescens, Fabr., from the 

 pine-forests of Aragon and Castile, showing the great variation 

 in colour of the two species in these districts, whereas the 

 allied forms occurring in the same places, viz., L. rtcbra, Linn., 

 Z. distigina, Chsir-p., L. unipunctata, Fabr., and L. sangimiolenta, 

 Linn., were perfectly constant; also Bermestes aurichalccits, 

 Kiist., which he and Dr. Chapman had found everywhere in 

 abundance in the old nests of the processionary-moth (Tkcm- 

 matopoea pitocampa, Schill.) on the pines in these forests. 



Dr. T. A. Chap3[an exhibited in illustration of his paper 

 living larvae of Hypotia corticalis, Schiff, as well as preserved 

 larva?, pupa-cases, imagines, and prepared wings to show the 

 neuration of that species.
