Bibliographical Notices. 155 



There is much general matter at the brginning and end of the 

 work, including several tables of geographical distribution. 



Dr. Arnold Pagenstecher, of Wiesbaden, is as well known to ento- 

 mologists as his cousin is known to the outside world as an oculist ; 

 and the publication before us is an elaborate monograph of the 

 butterflies of an interesting part of the Papuan fauna, some of the 

 islands of which were visited by the French exploring expeditions 

 about 60 or 70 years ago, when various butterflies were collected 

 there. At that time, some of the islands were known as New 

 Britain and New Ireland, but they have received other names 

 since they came into German hands. It is not to be expected that 

 so distant and outlying a fauna should contain many species which 

 are also found in Europe : the only species that strikes us, on 

 glancing through the paper, is Pleheius bceiicus ; but this is rather an 

 outlying European lepre.sentative of a tropical group than a specially 

 European species. The present paper on the Butterflies is to be 

 followed, later, by another on the Moths, which entomologists will 

 doubtless look forward to with much interest. 



The third work on our list relates to the Order Orthoptera, and 

 consists of lists of species captured in Batchian, Borneo, Celebes, 

 Halmahera (otherwise called Gilolo), Ternate, and Java, with de- 

 scriptions of numerous new species ; and tables are given of the 

 species included in some of the genera. The descriptions strike us 

 as being, in many cases, rather too short to be quite sufficient for 

 identification ; but the measurements are carefully given in all 

 cases, and a considerable number of species are figured, sometimes 

 the whole insect, and sometimes only a leg or pronotum. This work 

 will be very useful to students of Orthoptera, who, however, we fear 

 are not too numerous at present. 



JS^ew Zealand Moths and Butterjlies {MacrO'Lepidoptera). By G, V. 

 Hudson, F.E.S. (Author of ' An Elementary Manual of New 

 Zealand Entomology'). With 13 Plates. 4to, 1898. West, 

 Newman, & Co. Pp. xix, 144, 



The Eauna of New Zealand, as might be expected from its outlying 

 position, is comparatively poor, but extremely interesting from the 

 number of indigenous species absolutely peculiar to the islands. As 

 regards Lepidoptera, the first attempt to bring together the scattered 

 information existing on the subject was made by Dr. A, G. Butler 

 in 1874, who included au account of the order in the " Voyage of 

 the 'Erebus' and 'Terror,'" enumerating 318 species. Of these, 

 132 were Macro-Lepidoptera, and are represented by 234 species in 

 Mr, Hudson's work, the number of species detected in New Zealand 

 having been nearly doubled by the present time. Consequently we 

 shall probably be not very far wrong if we assume the total number 

 of New Zealand species now known to be about 600, which at a 

 moderate estimate we may expect may ultimately be raised to 800, or 

 perhaps even lOOO. The majority of these are moths. Of butterflies 

 Dr. Butler enumerates 9, of which one at least is very doubtful ; 

 Mr. Hudson admits 15, and mentions 5 other reputed species, 3
