176 THE CANADIAN ENTOMOLOGIST. 



shade at internal margin more diffuse. Hind wings immaculate beneath. 

 Abdomen dusky along the venter. 



Length of primary 18, of the body 12 m. m. 



Enterprise, Fla., May 28. 



The male is the more gaily colored, and has the blue reflections more 

 noticeable.

% . There are no ocelli, and thus there is a resemblance to the 

 Geometridae in a form resembling the Fasciatae in the long labial palpi. 

 The cut of the wings rather resembles Endropia. The labial palpi are 

 extended straightly forwards for more than twice the length of the head. 

 The palpi are divaricate, the third joint linear, elongate, more than half 

 the length of the second. Antennae simple, comparatively short ; the 

 genus seems distantly related to Syllcctra. Fore wings 12 veined, no 

 accessory cell ; veins 7, 8, 9, thrown off near together from the upper 

 extremity of the cell ; cell incompletely closed ; 5 nearer to 4 than to 6 ; 

 8 to apex. The position of 5 seems to me decisive, and that we have to 

 do with a Noctuid. Hind wings 8 veined, 3 and 4 from one joint, 5 near 

 4 ; cell closed by a fold or obsolete vein ; 5 hardly weaker than the rest. 

 The divided frenulum indicates the sex of the specimen. The frenulum 

 seems to be homologous with the marginal or sixth principal vein of butter- 

 flies. Mr. Scudder has pointed out to me that this number is sometimes 

 present in the higher groups. The frenulum cannot be considered a special* 

 ized hair. I have before come to the conclusion that it represents a missing 

 vein ; the reason for its complexity in the female I cannot yet suggest. 

 In the new form the legs are slender, long and unarmed. The entire 

 insect is pale ochreous, shaded with rusty, and in color and ornamentation 

 resembles some of the Geometridae. The fore wings have common wavy 

 rusty lines, and are mottled or subreticulate in appearance. A median 

 line bent at the middle of the wing, where it unites with an outer line 

 from the costa, and thus sketching the figure of a crooked Y, is notice- 

 able. Beneath the same markings come out, the broader rusty lines of 

 the upper surface being reproduced on a yellowish ground. Length of 

 fore wing 17 m. m. 



Two specimens collected at Fort Capron, Fla.; the largest is before 

 me. I am much indebted to Mr. Geo. Dimmock for his preparation of 

 the wings of the specimen by a valuable process discovered by him, an 

 account of which was read before the American Association for the 

 Advancement of Science.
