To date but two of the contemplated six parts of the work have 

 appeared. In the first part, in an introduction, the history of the 

 family is reviewed, beginning with the tenth edition of Linnseus's 

 " Systema Naturae.'" This is followed by a discussion of the general 

 characters of the family, the early stages, and the subdivision of 

 the family. 



Three main groups are recognized which are represented by six 

 subfamilies, four contained in group A, and one each in the other 

 two groups, B and C. Group A contains the subfamilies Brephinse, 

 CEnochrominse, Hemitheinae (;^= Geometridae), and Acidalinae {^■ 

 Sterrhinre)^; group B consists of the Larentiinae (= Hydriomeninae 

 together with Dyspteridinae) ; and group C of the Geometrinae (= 

 Ennominae). 



Besides the introduction, the first part of the work contains the 

 revision of the Brephinae. The author recognizes in this subfamily 

 two genera and seven species; Brcphos typified by B. notha of 

 Hiibner has two sections, the second of which contains our North 

 American species, iiifaiis and flctcJicri. Mclaiiis Boisd. and califor- 

 niciis Boisd., the specific identification of which has not yet been pos- 

 itively established, are mentioned in a note. Lcncohrcphos contains 

 only two species of which one, hrcphoidcs, occurs in America. This 

 part of the work is illustrated by one plate showing structural char- 

 acters of the family, and a moth of each genus and section of the 

 Brephinae. 



The second part of the work (i04me fascicule) deals with the 

 Qtnochrominae, which is admitted to be a fusion of a number of small 

 groups generally accepted as representing the more ancestral forms of 

 the Geometridae. The subfamily is divided into three tribes. CEnoch- 

 romicae, the first and largest of the tribes, contains 96 genera and 

 over 400 species, about 35 of these latter being new. The tribe is 

 world-wide in its distribution but is predominantly Australian, is but 

 weakly represented in the palearctic fauna, and contains but one 

 nearctic species, Alsophila pomctaria. Ametridicae and Hedylicae are 

 relatively small tribes with a neotropical distribution, consisting of 9 

 genera and 46 species almost evenly divided between them. The 

 former contains the only other two CEnochromids which occur in our 

 fauna, Aniietris (Mccoceras) nitocris and Ahnodcs tcrraria, both 



^ Synomila, Paota and Hccmatopis are included in this subfamily.
