is quite correct in calling attention to the particular necessity in this group for good 

 material from which to describe. The want, perhaps, of such material led Mr. Edwards 

 to describe S. rutilans six times over. A large number of sexual determinations by Mr. 

 Edwards are corrected by Mr. Beutenmuller, so it seems hardly possible for anyone to 

 have worked with less judgment. The list of the clear-wings in the New York Check 

 List was drawn up, with the rest of the list, by the writer of the present lines, who at 

 the time merely sent the last proof to the late Mr. Hy. Edwards for his revision. Mr. 

 Edwards added, in explanation, the two foot notes on page 12 and signed these, and 

 made one or two changes in his names for genera on page 11. The writer is also 

 responsible for the list of the clear-wings, since he originally wrote the same, and not 

 Mr. Edward?. The explanation is here given, as the list has been erroneously alluded 

 to as the work of Mr. Edwards. In the Philadelphia list the New York list is generally 

 copied, but lustrans is wrongly given to Mr. Hy. Edwards, and an implication is 

 conveyed in the preface that Mr. Hy. Edwards was the author of the lists of the clear- 

 wings, which is here corrected. The writer trusts that Mr. Beutennmuller will continue 

 his studies and that lepidopterists generally will help him in every possible manner. It 

 is a matter of great satisfaction that Mr. Beutenmuller's timely work is also of such good 

 quality. The writer would merely reclaim his Sesia pictipes, which is also given to Mr. 

 Hy. Edwards, on p. 134, and draw attention to the excellent description of the habits 

 of this species given by the late Dr. Bailey in the pages of the American Entomologist.

A List of the Butterflies of Sumatra, with special reference to the species occurring 

 in the north-east of the Island. By L. de NiceVille and Hofrath Dr. L Martin. 

 Calcutta. Reprinted from the Journal of the Asiatic Society of Bengal, 1895. 



This list of seven hundred and fifty-six species of butterflies taken in a limited 

 portion only of the great Island of Sumatra, gives one some idea of the wealth of the 

 insect fauna in tropical regions. In a very interesting introduction the authors give a 

 brief description of the Island, which is nearly »s large as France and is bisected by the 

 equator, and relate the difficulties that have to be surmounted in the formation of a 

 a collection of its butterflies, which can only be effected by employing nativps, who have 

 first to be taught and trained for the purpose. Dr. Martin lived for thirteen years on 

 the Island and has thus been enabled to add very interesting notes on the distribution, 

 scarcity or rarity, habits, season of occurrence, etc., of a large number of species. One 

 may, therefore, open the list anywhere and find not a mere record of names, but highly 

 interesting details regarding the butterflies. As might naturally be expected, the pre- 

 paratory stages of the majority of the species are as yet unknown.

A List of the Butterflies of Sikhim, by Lionel de Niceville, F. E. S., etc. Calcutta : 

 from the Gazetteer of Sikhim. Printed at the Bengal Secretariat Press. 



Probably no part of the great British Empire of India and its tributary States has 

 been so fully explored by the collectors of butterflies as the country of Sikhim, which 

 includes the famous health resort of Darjeeling, about 7,000 feet above the sea, on the 

 slopes of the Eastern Himalayas. Consequently the author is able to record in this list 

 no less than six hundred and thirty-one species, which he considers a near approach to 

 the maximum number that can be discovered. Certainly it is a goodly number, and one 

 hard to be realized by a dweller in these northern and much less luxuriant regions. And 

 what splendid creatures they are, with their gorgeous colouring and infinite variety of 

 shapes and hues. Nearly fifty species of Papilios alone are recorded, and more than one 

 hundred and fifty Lycsenidse, the greater number of which belong to genera that are 

 entirely unknown to us here.
