Family GEOMETRIDAE. 



Phasiane mellistrigata, Orote, Plate 1, fig. 11. $ . 



Labial palpi convergent, extended beyond the front, the minute third 

 article naked. Antennae scaled, simple. Maxillae moderately stout. Vein 5 

 of the secondaries absent. Dark steel gray. Wings ample ; primaries -with 

 straight costal edge, bluntly acuminate apices, external margin slightly 

 rounded. Secondaries full, a very little depressed on external margin oppo- 

 site the cell. Fore wings bright clean steel gray ; a distinct even continued 

 narrow, slightly oblique, bright ochreous transverse anterior line with a light 

 preceding shade, discontinued superiorly. A dark discal streak, above which, 

 on costa, the very indistinct median shade line is more distinctly incepted. A 

 very distinct double bright ochreous transverse posterior line, followed by a 

 distinct black shade and running from internal margin, a little unevenly and 

 outwardly obliquely to vein 7, where it is arrested, connected with the costa by 

 a narrow black line placed inwardly. Subterminal line appearing as a vague 

 festooning outside of the black shade. A very fine terminal line appearing by 

 interspaceal dots. Fringes concolorous. Hind wings a little paler, mottled, 

 deepening in color outwardly, with a distinct median even once angulated 

 dark line, and a fainter subterminal shade. Beneath, paler, mottled ; the veins 

 picked out by testaceous scales ; the costal edge a little stained ; markings 

 improminent. Body concolorous. Hind tibiae with middle and terminal

Expanse, 1.10 inch. Halitat, Buffalo, N. Y. 



We have only the female of this species in the collection. 



Mellilla, n. g. 



The body is narrow and linear ; the abdomen as long as the sec- 

 ondaries, the internal angle of which it slightly exceeds. Labial 

 palpi dependent, short, but little exceeding the front. No ocelli. 

 Male antennae bipectinate ; the pectinations are obtuse, and proyided 

 with setal hair ; there are about eighteen pairs on each antennus, 

 and they gradually decrease in length to the tip, where they become 

 obsolete. Maxillae moderate. Wings long. Primaries with straight 

 costal and parallel internal margins ; external margin rounded, a 

 little shorter than usual. Veins 3 and 4 thrown off together; 5 

 independent, equidistant between 4 and G ; 7 and 8 together from 

 the extremity of the long and narrow accessory cell, 7 to external
