The yonngesl work on I lie .V////?//y/c/rtc of the gioliu is contained in Kirliy's 

 <'a/fi/or/'ic of LepiiloptiTd I Ictiivrfni, (IMI:.'). A« a list of names this cataiugne 

 has been of great help to ns. The dassitication adopted in it has been mneh 

 Munied liy some anihors us b('ing arljit rary. Bnt we think tliat one sinjnid not 

 exjieel loo ninch fiuni a catalogne. Even the liest is full of errors, as a 

 eataloguer of in.seels cannot possibly have iiitriiisically worked out all the groups 

 catalogued. 



Besides these live general works, there are numerous treatises dealing with 

 (lie Sj/Ziini/if/ac of certain restricted districts. Apart from a host of poimlar 

 handbooks, there are two works on Ihe I'alaearetic Hawk Moths wordiy of 

 special notice. Tiicse are liy Ikrtel, in Kiilil, ( i roti-^iscli m . vol. ii., and liy Tutt, 

 I hit. Li' II. vol. iii. Hartel gives lengthy and generally accurate descriptions, 

 but relies (uo much on others, whose errors he rejieats without having examined 

 the insects himself and formed his own ojiinion. Tutt's work is of quite a 

 dilferent kind. It is the most intrinsic ever written on Palaearctic Lepidoptera. 

 The third volume comprises only a portion of the Spliiixiiilnc ; the remainder of 

 the family will appear in the fourtii. The work will be uf the greatest help 

 to the scientist who knows the matter well enough to lie alile to distinguish 

 between what is scientific and what appears merely in a scientific garb. The 

 usefulness of the work could have been improved, we think, liy a condensing 

 of the contributions of the collaborators, and mistakes could iiave lieen avoided 

 by the omission of references to foreign sjiecies with which the respective 

 collaborators were not sufficiently acquainted. However, as it is, there is nothing 

 written anywhere on European Lepidojifera coming up to it in thoroughness. 



The Indian •Spliingidat' are dealt with by Hamiison in Blanford, Fmina 

 Brit. India, Moth» \(il. i. (1892). The volume should be consnlfed with some 

 caution, .since many distinct species are treated in it as being identical. 



■flie species occurring in the Philippines are contained in Semper, >ivlniidl. 

 I'l'ilijjp. vol. xii. (I'^i'li), where many figures of larvae and pujiae are given. 



Miskin gave a catalogue of the Australian Hawk Moths in the I'ror. No//. 

 Soc. Queiui.'iland vol. viii. (ISHl). 



A nionograpli of the North American SjihiiKjiduf by J. Smith is contained 

 in the Trans. Amer. Knt. Soc. vol. xv. (188S). It is the liest work on Xearctic 

 Hawk Mot lis, though the classification is faulty in many respects, owing to 

 Sinitli's limited accjuaintance with the forms not found in North America. 



The Cuban sjiecies are described and catalogued by Gmte and Robinson in 

 the .Joar. Ent. Soc. Plnludelphiu vol. v. and vi. (18G5. IftlOT^, and again by
