252 THE entomologist's record. 



species is met with sparingly in some restricted areas of Belgium. lie 

 says that an examination of the genital organs gave him no con- 

 clusive results on the observation of external characters only. He 

 gives a table of the various named forms of C. palaeno, their 

 distinguishing characteristics and the areas over which each form 

 extends. The large form with very yellow ^ named europome is the 

 one taken in Belgium. 



In the Irhh Naturalist for July the Kev. W. T. Johnson reports 

 the occurrence near Belfast of Piiiiialia pedaria 9 (pilosaria), about 

 February 27th, and on March 17th of Ahophila aesciilaria at 

 Poyntypass, It appeared to us that these dates, compared with those 

 for the present year in England, were very late. In the August number 

 G. H. Pentland discusses the " Increase and Decrease of some Insects 

 in the County of Louth during the last fifty years." He says that, 

 " Ten or twelve years ago we were invaded by Sirex giijas. This 

 formidable looking creature increased very fast and soon ever}^ fallen 

 silver fir or gate post of that timber was riddled with them." He 

 goes on to say, " Hard on the heels of the Great Wood- Wasp came his 

 enemy. Four years ago I got my first specimen of Ehijssa persnasoria, 

 the ichneumon-fly that preys on the grub of the wood-wasp. Since 

 then it has increased wonderfully." One would like to know in 

 what way the ichneumon found out the colony of wood-wasps after 

 the six or eight years of immunity from attack which the latter had 

 apparently enjoyed. 



George Herbert Grosvenor, M.A., F.E.S. 



By the death of George Herbert Grosvenor, who was drowned at 

 Polzeath on September 4th whilst heroically endeavouring to save the 

 life of a friend, the Science of Entomology has lost one of the most 

 promising of her younger workers. Entering Harrow as a classical 

 scholar he was equally distinguished for his mathematical ability. 

 From Harrow he took a Biological Exhibition at New College, Oxford, 

 and after taking first class honours in the final Science School of 

 Natural Science, he was elected to the Oxford Table at the Naples 

 Marine Biological Laboratory. Here he carried out a remarkable 

 piece of research on the origin of the nematocysts in Aeolids. His 

 paper on the subject was read before the Royal Society and he was 

 awarded the Rolleston Prize in 1904. On his return to Oxford he 

 undertook the organisation of the School of Economic Entomology, 

 and having been awarded a Carnegie Scholarship had recently visited 

 the principal Entomological Research Laboratories in the United 

 States. Of a singularly modest and retiring disposition, his great 

 ability and remarkable clearness of thought were perhaps best 

 appreciated by those whose good fortune it was to be his intimates. 

 His great success as a teacher was due not only to his com- 

 prehensive knowledge but also to his power of imparting to his 

 pupils much of his own enthusiasm and love of the subject. Those 

 who were present at the second International Congress of Entomology 

 will recall the. efficiency and courtesy with which, as joint secretary, 

 he assisted in the organisation of the meeting. His name will be held 

 in high honour no less for his life than for the manner of his 

 death.— H.E.
