1140 THE BUTTKKFLIKS OF NEW ENGLAND. 



long as broad, increasing very regularly in size, to the third joint from the tip, wliere 

 it commences to diminish, the last two joints forming a short, l)luntly rounded, coni- 

 cal apex ; on the middle of the under side is a rather large, median, longitudinal, con- 

 nected sulcation, beyond the club interrupted at each incisure, and extending more 

 than half way down the stalls. Palpi slender, delicate, projecting horizontally, nearly 

 or quite half as long again as the eye, tlie last joint about half as long as the penulti- 

 mate, and longer than the basal joint ; joints furnished beneath with a thin fringe of 

 very long hairs, projecting downward and compressed in a vertical plane, excepting 

 on the last joint, where they are recumbent and seem to envelop it. 



Prothoracic lobes obsolete. Patagia minute, nearly flat, a little more than half as 

 long again as broad, tlie basal portion nearly circular, produced posteriorly to a trian- 

 gular lobe with nearly straight sides, tapering to a very bluntly pointed apex. 



Fore wings (40 : 5) scarcely less than twice as long as broad, the costal margin 

 very slightly convex ($), or nearly straight (^), the upper three-flfths of the outer 

 border forming a very large and broad dentation, subfalcate in the (?); the upper 

 portion, as far as the middle of the lower subcostal interspace, is slightly convex, the 

 apical angle being exceedingly broadly rounded, and the margin having a general 

 direction of 120° with the costal margin ; here it recedes suddenly at a right angle 

 and passes, in a rather sliallow and broad concave curve, to the middle median nerv- 

 ule, and then recedes again with a full curve to the straight inner margin. Costal 

 nervure terminating somewhat beyond the middle of the costal border. Subcostal 

 nervure with three superior branches, the first arising about the middle of the upper 

 margin of the cell, the second at the apex of the cell; the third beyond the cell but 

 nearer to it than the first branch is, itself forking at a short distance from its origin. 

 Cell considerably more than half as long as the wing, and three and one-half times 

 longer than l)road. 



Hind wings with the costal margin a little convex at base, beyond straight, the outer 

 margin very strongly and regularly rounded, a very little fuller in the $ than in the 

 $ , the angles entirely rounded, the inner margin nearly straight, slightly emarginate 

 in the middle of the apical half, the angle broadly rounded. Costal branch straight, 

 directed upward ; cross veins closing the cell striking considerably nearer the second 

 divarication of the subcostal nervure, than that of the median nervure. 



Androconia broad, parallel sided, with a dense and ver3' short fringe at apex. 



Fore tibiae as long as (?) or three-quarters the length of ( (J ) the middle tibiae ; fore 

 tarsi as long as the fore femora and middle tarsi and not much sliorter than the hind 

 tarsi; hind femora about four-fiftlis (<?) or a little more than three-fifths ( $ ) as long 

 as the middle pair. Femora supplied beneath with a rather thick fringe of long hairs 

 becoming shorter apically. Tibiae armed rather abundantly and irregularly with 

 short and very slender, inconspicuous, nearly recumbent spines, and apparently desti- 

 tute of spurs. First joint of tarsi equalling the three succeeding combined, the fifth 

 as long as the third, and the fourth scarcely more than half tlie length of the second; 

 joints provided abuntlantly with spines, above shorter than below and arranged only 

 in indefinite roM's ; below with four rows, two on either side, of rather long and very 

 slender, frequent spines, the apical ones of each joint larger than the other, though 

 butslightly ; claws very small, but little divaricate, compressed, bitidfor two-fifths their 

 length, the upper branch the longer, curved but comparatively little excepting near 

 the tip, tlie lower the broader, much more curved, both finely pointed; paronychia 

 simple, consisting of a long and slender, lamellate lobe, nearly as long as the claw, 

 fully as broad as the claw at the base, tapering a little, bluntly pointed, concealing 

 most of the claw; pulvillus moderately large, longitudinally quadrate, twice as long 

 as broad, placed at tiie extremity of a broad, stout pedicel, half as long as the claw. 



Abdominal appendages: Upper organ large, long, depressed, the centrum equal, 

 the hook tapering and curved downward ; clasps subovate, rather regular, but little 

 convex, directeil horizontally backward. 



Egg. Subfusiform, but tapering very much more above than below, broadest in the 

 middle, broadly truncate at base, narrowly truncate at summit, which is about half
