and confusion which niusf inevitably ensue from tliiy indiscriminate formation of nuw genera and new species, witli tlieir nHendant, evils of useless and 

 cumbersome synonyms. 



The small collection of Icpidoptcra which the Swedish naturalists obtained during the short stay of the Frigate in the waters of Port Jackson, has 

 afforded to Mr. Wallenj^ren an opportunity for the construction of a few new genera and twenty-three new speciea, the majority of which we think must be 

 rejected. Bearing in mind that these insects were found in an English colony and within the precincts of Sydney, a large and populous city, many of whose 

 inhabitants are highly interested in the various branches of Natural History, it does appear somewhat remarkable that Mr. Wallengren should not have consulted 

 the works of English authors before he issued his publication :— a pulilication which must be taken as a Swedish National production, and one which ought to be 

 looked upon as a correct authority for fnture writers. 



The knowledge which this gentleman possesses of our eniomological literature must indeed be very vague and meagre as evinced in the only references, 

 unsatisfactory indeed, he has made to it, and the whole of which we now extract, viz. : — " Species nostra, ut videtur, L. nasuta, Lewin, et Boisd. quam maxime 

 "affinis. * Opusculum Lewini non vidimus," p. 367. " Species nostra forle sit eadem ac species Donovani, sed figuram ejus ad manum non habuimus," p. 368. 

 "Species cum C. strigata, Lewin, sine dubio affinitatem habet quam maximam, sed figuram hujus speciei, quam dedit auctor, non vidimus," p. 386. ' 



Since the days of Lewin and Donovan, however, a host of able writers on exotic entomology have appeared in Great Britain, and had Mr. Wallengren in 

 the performance of the task imposed on him by his government, taken the ordinary precaution of examining their works, whicli are freely illustrated by coloured 

 plates, he could easily have satisfied himself that most of his new creations had been previously described, nay, many of them figured. In support of our assertion, 

 we cursorily take bis list now lying before us, and as the insects we have selected are well known, we can without much (litHculty point out in the following 

 species the discrepancies which exist between his momenclature and that of other autboi-s.
