surprising is tlie absence of the familiar genus 

 Callimorpha with its European and Asiatic 

 species. If this genus belongs to the ISToctuidas 

 by the author's classification, we think the 

 scheme is some way at fault, for the insects 

 are certainly Arctains in their broad char- 

 acters. Holomelina (Euhaphe) immaoulata 

 Eeak. has escaped notice, doubtless owing to 

 Kirby's erroneous reference of it to the genus 

 Eudule (Geometridse). The species Euhalesi- 

 dota otho Barnes, Dodia albertce Dyar and 

 Pseudalypia geronimo Barnes, appeared too 

 late in description to be included. Most of 

 these omissions are, we presume, intentional, 

 but some seem due rather to the method by 

 which the work has progressed, by which one 

 family is completed before the critical study 

 of the next one has been begun. Thus species 

 which have been wrongly referred by cata- 

 loguers are liable to be overlooked. On page 

 79 Bertholdia hraziliensis is described as new. 

 The name must fall before B. soror Dyar 

 (Proc. Ent. Soc. Wash., IV., 391, May 3, 1901), 

 which seems unquestionably the same species. 

 On page 267 our author places Spilosoma con- 

 grua Walk, as a synonym of Diacrisia virgin- 

 ica Fab. We cannot agree to this, since it has 

 been shown that a part of Walker's types were 

 a distinct species, antigone Streck., and to this 

 his description apijlies. Arciia complicata 

 Walk, is made a synonym of A. quenseli Payk. 

 We had always supposed it to be a form of 

 ornata, which occurs in the same region (Brit- 

 ish Columbia), whereas quenseli is an Alpine 

 form from the Alps, Labrador, White Mts., etc. 

 But the author has Walker's type and should 

 know. We shall be interested to see if quenseli 

 can be found again in Vancouver Island. 



Condensed descriptions of the larvse of sev- 

 eral species are given, but in a sporadic 

 manner. Most of the life histories published 

 within the last few years are included, but 

 practically all the older ones published more 

 than ten years ago are omitted. Doubtless it 

 wovild have added gi'eatly to the author's labors 

 to have made a thorough search for all larval 

 descriptions, but surely the North American 

 species might have been included as they have 

 been very completely catalogued in a bulletin 

 issued by the U. S. National Museum in 1889. 



We do not, of course, desire to depreciate the 

 value of this work, which, as we have before re- 

 marked, is a great boon to working entomolo- 

 gists, enabling us to identify our species far 

 more readily than ever before. For, unlike 

 many published synopses, Hampson's tables are 

 practicable, not containing contradictions nor 

 hair-splitting differences. Variation within 

 specific limits may invalidate some of the char- 

 acters which he uses, but we find this a very 

 minor objection.

gaupp's anatomy of the frog.* 

 This is not the first time that the present 

 work has been noticed in this journal. The 

 other parts as they have appeared have been 

 reviewed as follows : Parts I. and II., Sci- 

 ence, Vol. VII., p. 463; Part III, Science, 

 Vol., X., p. 491. 



The present part deals with the viscera, the 

 next and conekiding ' Heft ' is to take up the 

 integument and sense organs. The organs 

 are discussed in the following order : Diges- 

 tive tract, respiratory organs, thyroid gland, 

 derivations of the pharyngeal region, urogen- 

 ital organs, cloaca, and the ecelomic cavities. 

 As with the portions of the work already pub- 

 lished it is impossible with this to analyze the 

 facts presented and to point out the features 

 which are novel. Attention, however, must be 

 called to the broadly morphological aspects of 

 the work. Dr. Gaupp has given us not only 

 the anatomy of the adult frog but has empha- 

 sized the bearings of the various structures. 

 Thus at the beginning we have an account of 

 the developmental history of the head-gut re- 

 gion without which the account of the deriva- 

 tives of the branchial region would lose much 

 of its interest. In the same way the urogenital 

 structures are introduced by a longer account 

 of their history. Then there is a valuable 

 summary of what is known concerning her- 

 maphroditism in the frogs. The illustrations 

 throughout illustrate the frequent use of the
