216 THE ENTOMOLOGIST. 



and no linear arrangement — genera, families, orders, following one 

 after the other — can exactly express the true relationships between the 

 groups, which must necessarily show affiuities in various directions. 

 But in striving after a natural system, making use in his work of all 

 that he can learn of the inner and outer structure and development of 

 the creatures which he classifies, the systematist is doing his part to 

 read the history of insects in the widest sense of the term. And he 

 will, if wise, hold with a light grasp to his systematic divisions, re- 

 cognising that the increased knowledge which makes the line between 

 two species or two orders appear blurred and uncertain, throws a 

 clearer light on the object of all entomological work, which is to trace 

 the course of evolution in insect life." 



Mr. Carpenter is of opinion that the old style division of the Lepi- 

 doptera into Rhopalocera and Heterocera is not scientific, and in this 

 view he is in accord with most recent authors. He, however, also 

 objects to the divisions Jugataa and Frenatae, proposed by Comstock ; 

 to the Incomplete and Obtectae, of Chapman ; and to Packard's 

 Haustellata with Laciniata as a sub-order. In rejecting all divisions 

 between the order and the family he is in unison with Hampson. The 

 families adopted are forty-seven in number, and are briefly referred to 

 in the following sequence : — Micropterygidas, Eriocraniidaa, Hepialidaa, 

 Zygaeuidaa, Chalcosiidas, Limacodidae, CastniidaB, Megalopygidas. Psy- 

 chidae, Heterogynidas, Cossidaa, Sesiidae, Tortricidae, Tineidaa, Ptero- 

 phoridas, Orneodidaa, Pyralidaa, Thyrididae, Drepanulidae, Callidulidae, 

 Lasiocampidaa, Lymantriidaa, Hypsidaa, Arctiidas, Noctuidae, Argari- 

 stidas, Syntomidaa, Thyatiridaa, Notodontidae, Sphingidaa, Dioptidaa, 

 Geometridaa, Epiplemidae, Uraniidaa, EpicophdaB, Bombycidas, Euptero- 

 tidae, Ceratocampidae, Brahmaaidaa, Saturniidae, Hesperiidaa, Lycaenidae, 

 Lemoniidae, Libytheidaa, Papilionidaa, Pieridaa, Nymphalidas. 



We have great pleasure in bringing this work to the attention of 

 our readers, as we are sure that it will prove to some of them exactly 

 the book they have been anxious to obtain. It is liberally illustrated, 

 well arranged, and printed, and the price is exceedingly low.
