ATRYTONE. By Dr. M. Draudt. 



93'; 



somewhat reddish-yellow, and on the forewing it has postdiscal, subapical bone-coloured spots and 2 smaller 

 ones in the cell-end. Beneath paler, marked as above, on the hindwing besides with a light longitudinal ray 

 from the base to the middle of the distal margin. Atlantic States. 



P. psaumis G. d- S. (182 c) is allied to the preceding, but the 2 spots between the median veins are psaumvs. 

 strongly angled. The mider surface is much darker and more monotonous. Mexico (Jalisco). 



P. azin Mab. is likewise very closely allied, but much smaller. Colombia, azin. 



91. Genus: Atrytoiie Scddr. 



The antennae scarcely attain half the length of the costal margin, the club is short and thick with a 

 short hook-shaped apex; terminal joint of the palp very short, quite abruptly ending in a short apex. Body 

 strong, almost squat ; middle and posterior tibiae strongly spined. The ^ is without a pronounced scent-scale 

 stripe, but there are often in its place modified and therefore inconspicuous scent-scales of the ground-colom\ 



A. delaware Ediv. (= logan Edw., vitellius Streck. nee F.) (182 c) is above reddish-yellow, towards 

 the margin on the forewing broadly, on the hindwing narrowly darkened with a spot-like darkening behind 

 the cell. The 2 is larger, with a darkened basal half of the forewing. Beneath orange-red, at the base and proxi- 

 mal angle of the forewing blackened. Pennsylvania, Florida, Mexico to Guatemala. For this species the genus 

 Anatrytone was established. 



A. zabulon Bsd. cL- Lee. (= erratica Plotz) (182 c). This species and the following have brought 

 about an amazing muddle in the literature pertaining to them. It is above on the whole lighter; more sulphur- 

 coloured, the bordering of the dark distal margin proximally on an average more dentate, more distinct. Beneath 

 the base of the hind-n'ing is less extensively darkened, in the yellow discal area there are particularly towards 

 the proximal margin small brown spots. Southern Atlantic States as far as Mexico. 



A. hobomok Hmr. (= zabulon Plotz) (182 c, d) is above mostly more reddish-yellow, the black distal 

 margm proximally less irregular, more blurred. Beneath the base of the hindwing is broader and more deeply 

 darkened, dark spots in the median space are nearly always absent. — f. pocahontas Scddr. (^ quadaquina 

 Scddr.) (182 d) is a dimorphous $-form very much darkened above and beneath, above quite blackish-brown 

 with minute bone-coloured spots. Atlantic States. 



A. rolla Mab. (= piso Plotz) (182 d). Above almost as hobomok, but the inner-marginal part of 

 the hindwing is much broader black. Easily separable by the quite reddish -yellow hindwing beneath with 

 indistinct ferruginous brownish spots, the inner-marginal area being scarcely darkened, and with a small black 

 cell-end dot. Costa Rica, Panama to Colombia. 



A. perfida Mschlr. (182 d) is very closely allied to rolla, it is more slender, with more tapering wings, 

 lighter yellow, the inner-marginal part of the hindwing is not so broadly darkened, the cell-end spot of the 

 forewing is somewhat larger. Beneath the proximal margin of the forewing is broader black, the apical part 

 fiery reddish-yellow; hindwing yellow without any markings at all, dusted somewhat reddish. Colombia. 



A. vitellius F. (= insularis Mab., hiibneri Plotz) (182 e) is externally quite similar to delaware; the 

 black veins are finely prominent, and the sirbmedian and cellular folds are towards the base striped black. 

 Beneath the blackening is absent at the proximal angle of the forewing, the hindwing is strewn with a grejdsh 

 yellow. West Indian islands, also from G-uatemala and the Amazon. 



A. mella G. cfc S. is very closely allied to perfida, but the margins of the wings are above broader 

 black, besides there is an interrupted, blackish-brown longitudinal stripe along the median. Mexico to Brazil 

 and Bolivia. 



A. eulogius Plotz (= mellona G. c& S.) (182c) resembles mella, the reddish-yellow colom- of the wings 

 is very much confined by broader margins of the wings projecting dentately or M-edge-shaped on the lower median 

 vein and above it between the veins. Beneath the hindwing is reddish-yellow, strewn with cinnamon-coloiu-, 

 with a lighter postdiscal band and cellular spot. Mexico, Panama, Guiana. 



A. gladolis Dyar is allied to mella. Above broadly yellow, veins and distal margin blacldsh; on the 

 median there is an irregular, black longitudiiral band, projecting at the end into the cell and from there on 

 the middle radial vein towards the margin; hindwing in the disc reddish-yellow, veined black. The $ is more 

 intensely marked black, beneath at the proximal margin of the hindwing with a broad black stripe. Expanse 

 of wings: 32 to 36 mm. British Guiana. The larva lives on sugar-cane. 



A. heberia Dyar. Above blackish-brown, costal margin as far as the cell-end reddish-yelloAV ; 3 sub- 

 apical and 4 postdiscal reddish-yellow spots, the lowest narrow, the spot above it rectangular, the second from 

 above wedge-shaped. Hindwing with a yellow cell-spot and 5 postmedian, wedge-shaped spots. Beneath reddish- 

 yellow, the inner-marginal part shaded with black, and in the disc veined black. Hindwing yellow with a broad 

 black triangular spot before the proximal margin. In the $ the spots are white, larger and more quach-angular,
