to those of the imago. It was found that complete regeneration of 

 parts did not occur until after several moults. Unless a very radical 

 removal of the leg be made, regeneration of the whole leg always takes 

 place after four or five moults. If the amputation be by clean incision, 

 regeneration takes a simple and straightforward course ; if crushing 

 take? place, various supplementary portions occur, and often duplication 

 of parts. The second paper is one by the Rev. G. Wheeler, " Suggestions 

 for securing Simplification and Permanency in Nomenclature." This 

 article should be read by every one who thinks he has an opinion on 

 Nomenclature, or who wishes to discuss this vexed question. The 

 pros and cons of priority are discussed with the worst instances of its 

 effects, Meigen's paper on Diptera, Linneus 10th versus 12th editions, 

 the notorious ari/its var. at't/on case, etc. Many instances are given of 

 the incidence of so-called " rules " on the permanence and fluctuation 

 of the signification of generic names. A considerable section is devoted 

 to the question, what is a name?, to Orthography and to emendation. 

 [We cannot refrain from adding a further example of Orthography, the 

 alteration of nickeriii (named in honour of Dr. Nickerl) to niccerli, 

 when it becomes absolutely unrecognisable.] After a few words on 

 Authorities and Availability, the author makes two suggestions 

 (1) That no name discovered in an earlier publication be considered 

 available if it displace one in unchallenged use for more than twenty- 

 five years previously, (2) That a generic name shall not be held 

 available in a different, but only in its recognised sense, or a restricted 

 or extended use of the same. Mr. Wheeler then discusses what 

 should be the duties of the International Committee and finally makes 

 some remarks on varietal and aberrational names and on the nomen- 

 clature of parallel variation, which we might possibly reprint with 

 great benefit to our readers who have not the opportunity of perusing 

 the arguments in the original paper. 



After a considerable interval another part, 18, of the Lepidopterorion 

 Catalof/Hs has been issued. It deals with the Sphini/idae : sub-fam. 

 Ambnlicinae, Sesiinae, and is by Prof. H. Wagner. As regards com- 

 pleteness this part appears, if one may judge by the number of references 

 given to Mimas tiliae (nearly seven pages), to be quite up to standard. 

 Aberrations and variations, as well as hybrids, are included. Nearly 

 ten pages are given to the references to Amorpha populi. 



Jn the fi'«^ Mo. Mcuf. for April Mr. E. A. Newbery announces an 

 addition to the British Coleoptera in the species Phili/dnis halophilus, 

 four specimens of which were taken by Mr. Claude Morley near Bawdsey, 

 Essex, in April, 1904 ; Mr. D. Sharp adds P. fuscipennis which he had 

 differentiated from P. nielanncephalus from many localities ; and Messrs. 

 J. C. F. and H. F. Fryer add Anthicus bifasciatus, which they found in 

 considerable numbers in old manure heaps near Chatteris, Cambs. 



In the Ento)itoloi/ical Neirs for April there is an appreciative notice 

 of the late Dr. Geo. Wm. Peckham, of Milwaukee, who passed away 

 on June 18th, 1914, at the age of 68. In conjunction with his wife 

 he wrote many articles and several books of their researches into the 

 Biology of Wasps aud Spiders, which are quite classical not only for 

 their scientific accuracy and originality, but also for their scholarly 

 and literary character.
