species. In tlae larva stage it shows a remarkable re- 

 semblance to the group next to follow. From the slenderness 

 of their bodies and the breadth of their wings the moths of 

 this group are likely to be mistaken by a young collector for 

 Geometridm. 



Genus 1. DREPANA. 



Antennae of the male pectinated, the pectinations not 

 continued to the tip, which is merely dentate ; fore wings with 

 produced and somewhat hooked apex, and hind margin 

 smoothly curved ; hind wings broad. 



1. D. falcataria, Z. ; falcula, >S'c/wjf. — Expanse l^to If 

 inch. Fore wings hooked : brown, with an oblique red-brown 

 stripe crossing to the apex, and, before it, an ovate grey-brown 

 blotch ; hind wings paler. 



Antennae of the male pectinated to near the tip, where the 

 teeth become prostrate and indistinct ; each tooth ciliated, 

 dark brown ; shaft paler brown. Head brown, pressed 

 closely to the thorax, which, with the abdomen, is slender, 

 light brown, the scales lying smoothly down except upon the 

 shoulder lappets, where they are longer and rather loose. 

 Fore wings broad, costa strongly arched, especially toward the 

 apex, which is gradually produced into a long and graceful 

 hook pointed at the tip ; hind margin sharply hollowed 

 beneath it, then rounded and very full round the anal angle ; 

 dorsal margin straight ; pale brown, with three slender, much 

 indented and zigzagged transverse lines, all expanded upon 

 the costa ; the third bends toward the apex in a long point 

 from which it turns back to the costal margin ; outside this 

 third line is a thick red-brown stripe, which, arising upon 

 the dorsal margin, proceeds with a smooth and regular curve 

 to the tip of the wing, where it becomes almost black ; before 

 this, in the middle of the wing and upon the third line is an 

 ovate grey-brown blotch divided by black lines ; preceding this 

 two black dots lie longitudinally in the discal cell. Outside 

 the curved stripe is a fourth, very slender, brown line, nearly
