New Species and Varieties of Geometridae. 



By Geo. D. Hulst. 



Some months since I began the study of the Geome/ridce of N. A., 

 having more particularly in view a looking into the systematic arrange- 

 ment of genera and species. With this object, in addition to my own 

 collection, I have obtamed for my use, wholly or in part .as Thave de- 

 sired, the collections of the L^pitlopterists in the vicinity of New York, 

 as well as of many others from other parts of our country. Many of 

 these are especially rich from the collecting of Messrs. Hy. Edwards, 

 Morrison and Doll, and variations from normal forms are largely repre- 

 sented. So far my study has been in the Ennomiiuv only. Mv con- 

 clusions as to genera I will probably not give until the whole family has 

 been studied. In the material at hand, I have found as they seem to me 

 the following new species and varieties. The generic references are to 

 be regarded as provisional. These descriptions ma\' be followed by brie 

 notes on already named species. 



I. Oxydia zonulata sp. nov. Expands 46 mm. Head and antenna pale ochre- 

 ous, the vertex, anterior edge of hind wing.s and abdomen .shading somewhat lighter. 

 Wings otherwise a pale yellow ochreous. T.a. line wanting. T.p. line present on 

 both wings, reflected on fore wings near apex towards costa at an acute angle, and 

 somewhat curved inwardly in its course across the fore wing; straight on hind wing. 

 Its color is buff on fore wing, tawny on hind wing. There is a small smoky spot 

 near anal angle. Beneath very light ocln-eous, witliout lines but with two or three 

 shadings near apex. 



The above is close to O . iniuidata Guen. but lacks the shadings o 

 the wings above, the cross line is not extended to the apex, and the fore
