end of August. I have no doubt he has. I have myself bred 2V. camelina, 

 dictcea, dictceoides, and dromedarius, from May to July, from autumnal 

 pupae. Now what I mean to say is this: the moths which appear in May 

 are the parents of another brood of moths in August. The moths which 

 appear in June are the parents of those pupae which Mr. Greene digs up in 

 August, and which he has tried to force, but without success. Some of these 

 latter are also doubtless the offspring of the dilatory pupae of the previous 

 autumn, which cannot make up their minds to emerge till August. Mr. Greene 

 seems to think it impossible for an egg of a Noiodonta to hatch, feed up, 

 and spin in a month's time. All I can say is this; on May 23rd., 1854, I 

 had a batch of eggs of N. ziczac and cucullina hatching; on June 23rd., 

 the larvae began to spin up. I certainly never have myself seen the larva of 

 N. dictcea spin up between leaves, and all those which I have had full-fed 

 in July invariably buried. I have not unfrequently, however, had the larvae 

 of camelina and ziczac from a cocoon between leaves. — H. Haepue Ceewe, 

 Stowmarket, May 8th., 1858. 



Nomenclature. — I have some thoughts of beginning an entirely new collection, 

 and in any case it would, I think, be a great boon to many if you would 

 tell us briefly, as at present nomenclature is at such sixes and sevens, since 

 Curtis's and Stephens's Catalogues, from what sources, in all the orders, 

 cabinets may best be named. The same also as to the foreign insects. — X. 



[Our correspondent will find most of the families in entomology well arranged 

 in the lists of the British Museum. Hymenoptera, by Smith; Diptera, 

 JSomoptera, and Nemoptera, by Walker; Hemiptera, by Dallas; Anopleura, 

 by Denny; Coleoptera, by White, J. Smith, and Walton. The best arrange- 

 ment of the Lepidoptera is that of Guenee. Mr. Doubleday has in the press 

 a second edition of his Synonimic list of British Lepidoptera, arranged after 

 Guenee. Mr. Stainton's list of the British Tineina is the best yet published. 

 There is a very good Catalogue of European Coleoptera called the "Stettin 

 Catalogue," which Mr. Stainton will send for seven stamps. Neither Curtis 

 nor Stevens will do in the present day for naming cabinets. Collectors must 

 not be too impatient; these are works requiring immense labour and great 

 knowledge, and are not very remunerative. Some of the British Museum 

 Catalogues are exceedingly well done, such as Smith's British Hymenoptera, 

 Walton's Curculionidce, etc. They are printed on one side for labels, as well 

 as in small treatises. Messrs. Dawson and Hamlet Clark have commenced a 

 Catalogue of British Coleoptera, but they have only as yet published the 

 Geodephaga. — Ed.] 



Hypercriticism. — Bad orthography is a great blemish in a work claiming 

 a scientific character. On pages 35 and 36 of "The Naturalist," the words 

 Menthastri and lubricipeda, are spelt wrongly no less than eight times. To 

 stay the progress of error, it would be well to correct these errors as early 

 as possible. — Thomas Chapman, Glasgow, May 6th., 1858. 



[Nothing in our opinion is so trifling as to see men claiming to belong to 

 a scientific community, wasting their energies in finding fault with other 

 peoples' p's and q's. There is no doubt that Fabricius spelt the names as
