36 COLEOPTERA. 



order to use it with any effect, they must (as in all difficult 

 subjects) give almost as much time and attention to the matter 

 as the author has given. 



Dr. T. Algernon Chapman, of Abergavenny, who (as 

 mentioned in Ent. Ann. 1869) commenced the study of Co- 

 leoptera last year, has proved that proficiency in Entomology 

 is hereditary (his father, Mr. Chapman, of Glasgow, being 

 well known, both as an observer and collector), by commu- 

 nicating to the pages of the "Entomologist's Monthly Ma- 

 gazine" some very interesting and original papers on the 

 oeconomy of certain wood-feeders, viz., Cryphalus binodulus, 

 Hylurgus pilosuSy Sylastes obscurus, Pldceojjhthorus rhodo- 

 dactylus, and all our Scolyti (except Ratzehurgii), occurring 

 in his district ; also on Octotemnus ylabriculus and the para- 

 sitism of Aj)hodius porcus upon Geotrupes stercorarius. 

 Being particularly deficient here in observers of Mr. Chap- 

 man's calibre, it is to be hoped that he will continue inves- 

 tigations so likely to redound to the scientific credit of his 

 country. 



Mr. Albert Miiller, the results of whose patient study of 

 the habits of certain minute Diptera in their earlier stages 

 have also been chronicled from time to time in the same 

 Magazine, has satisfactorily demonstrated that Balaninus 

 hrassiccB is not, as has been thought by von Heyden and des 

 Loges, a true gall-maker, but an inquiline. 



The Rev. H. S. Gorham and Dr. Power have demon- 

 strated — the former by his capture of the rare Leptinus in 

 numbers at Needwood, Staffordshire, associated with Bovihus 

 liortorum^ and the latter by finding Ceuthorhynchideus 

 pumilioj also in numbers, on Teesdalia nudicaulis (at Fren- 

 sham, Surrey, in April), — that my transfer of the notes of 

 Eichhoff' and Gerhardt on those subjects to the pages of the 

 same Magazine was not altogether useless, and have fully
