and October of same year, from ova laid by the first brood. — Mr. V. E. 

 Shaw, Hybernia progemmaria var. fuscata, and melanic Phir/alia jnlo- 

 saria, both from Saltaire. — Rev. C. R. N. Burrows reported that he 

 had bred LijccBna argiolm, in the spring of the current year, from 

 larvfe taken during the spring of 1905. 



Maij 15th. — Rev. C. R. N. Burrows exhibited preserved larva of 

 Leucania favicolor. — Mr. W. J. Kaye, Eupithecia helveticaria var. arceu- 

 thata from Surrey. 



J^me ith. — Dr. T. A. Chapman exhibited larvas of Etivanessa 

 antiopa in last stadium, from South France. — Mr. E. Harris, a series 

 of Hemerophila ahruptaria darker than the usual London form, bred 

 from light parents, the offspring of a cross between light and dark 

 forms. — Mr. C. P. Pickett, a cocoon of Plnsia moneta about twice the 

 normal length and open at both ends ; also Fidonia atomaria with two 

 extra rudimentary wings. Mr. Pickett reported that he had obtained 

 fifty ova from a pairing of Smennthus populi and S. ocellattis, and five 

 ova from a cross between S. ocellatus and S. tilice. 



June 18th. — Mr. A. J.Willsdon was elected a member. — Mr. A.Bacot 

 exhibited larvfe of Pyrameis cardid reared on burdock, which appa- 

 rently bore out a suggestion made by Dr. Chapman that the larva of 

 this species is more densely covered with hair in the last stadium if 

 fed on this pabulum as compared with thistle-fed larvae. — Mr. A. W. 

 Mera, Sesia culiciformis from Essex, with the band round the body 

 white instead of red ; also TtEtiiocampa opima from the Brentwood 

 district, where the collecting-ground was blackened by fire some years 

 ago. The specimens were of much lighter coloration than those taken 

 shortly after the fire, suggesting response to environment by some 

 more rapid means than selection. — Mr. C. P. Pickett, a rust-red speci- 

 men of Smerinthus tiii(t, S. populi with a lilac-tinted bloom on the 

 wings, and Procris genjon from Chiltern Hills. — S. J. Bell, Hon. Sec. 



OBITUARY. 



Baron Charles Robert v, d. Osten Sacken. — In the death of Baron 

 C. R. Osten Sacken, which took place at Heidelberg on May 20th last, 

 it may truly be said that Dipterology — or, in fact. Entomology — has 

 lost one of its brightest ornaments. For many years his general 

 knowledge of the Diptera exceeded that of any other student of the 

 Order. In many ways he constituted the beau ideal of a scientific 

 entomologist; absolute master of numerous languages, independence 

 of means, social rank, retentive memory, accurate observation, possessor 

 of an almost perfect library of works upon Dipterology, and polished 

 manners — these qualities all combined enabled him to hold the highest 

 rank in his special branch of science. The last work he published was 

 his autobiography, issued when he was seventy-five years old, and 

 since then (three years ago) nothing has appeared from his pen. In a 

 short notice it is impossible to do justice to his work, but it is duly 

 appreciated by all those who have had opportunities to profit from it.
