SEBALDIA; DOBERES; MASICES; ANTIGONUS; SYSTASEA. By Dr. M. Drafdt. 903 



E. chlorocephala sp. nov. (17<3 d) is somewhat doubtful as to its position. Smaller than pallida, other- cMorocc- 

 wise similar in the colour and marking, but the marginal area is not so broadly darkened, but only with a rather phala. 



narrow, darker submarginal line. Tlii-ee small, white subapical dots, the middle one being the smallest. Head 

 and collar with a metallic green reflection. Under surface almost as above, but the hindwings are much darker 

 brownish-black than the forewings. Bolivia (Rio Songo). 



33. Genus: Sebal<1ia Muh. 



Scarcely different from the preceding, but the ^ exhibits a hair-tuft at the base of the costal margin 

 of the hindwing above and a spot corresponding to it beneath. Only one well-known species: 



S. busirus Cr. (= sebaldus F.) (17(>e) is above deep dark brown with still darker macular markings, busirus. 

 beneath the anal distal-marginal part of the hindwing is of a bright orange-yellow, in the ^ with dark spots 

 therein. From Mexico through Central America, Venezuela, Colombia, South East Brazil to Paraguay. In 

 the Upper Amazon district the yellow of the hindwing beneath is reduced, in the Lower Amazon district and 

 Guiana, also in Colombia, it disappears altogether: f. obscura Mab. — The larva is violettish-brown with alter- uhiicura. 

 nately yellow and white belts, and lives on Citrus. 



34. Geiitis: ]>obc]*es G. d- S. 



Separated from Eantis by the longer terminal joint of the palpi and niuch less ensiform apex of the 

 forewing. The posterior tibiae exhibit only one pair of spurs and on the inside a hair-comb with short spiny 

 bristles in it. Costal fold absent. Only 1 species. 



D. hewitsonius Reak. (= mexicanus Fldr., ananius Plotz) (176 d). Light brown with 2 chestnut- /(Pi<v7so>?n/s. 

 brown costal-marginal spots, the proximal one I'ectangular, the distal one before the apex triangular, two undulate 

 darker bands particularly on the hindwing broadly surrounded with a lighter colour. Beneath especiallj' the 

 hindwings are strewn violet. Mexico. 



35. Genus : Masices G. d- S. 



Distinguished from the preceding genus by the longer antennal club and shorter terminal joint of the 

 palpi. The middle radial vein of the hindwing is almost absent. 



M. anticus Plotz (170 d) is dark blacki.sh-brown with a violet reflection. 2 black cell-spots and an anlicKs. 

 oblique band of the forewing expanded towards the proximal margin, the margin darkened. Hindwing the 

 same, but instead of the cell-spots there are 2 transverse bands. Beneath only little lighter, the cell-spots absent, 

 and the apical half of the forewing somewhat lighter. From East Mexico. — In West Mexico. Costa Rica and 

 Guatemala flies; f. sobrinus G. d- S., in which the apical half of the forewing beneath shows decidedly yellow sohrimis. 

 colour. The $ is considerably larger. 



36. Genus: Aiitigonns Hbn. 



Well distinguished by the peculiar shape of the wings: the proximal margin of the forewing is very 

 concave, the proximal angle extended to a lobe, the hindwing is extended like a tooth on the upper radial vein. 

 The antennal club is semicircularly bent. Palpi as in Eantis. Posterior tibiae with hair-pencil and 2 pair of 

 spurs. The ^ exhibits a costal fold. 



A. nearchus Latr. (= ustus Hbn., pausus Warr., hippalus Fldr., sata.spes Fldr.) (Hfie) is above ncarchus. 

 deep blackish-brown with darker macular bands, between them in some places with a violet reflection. The 

 under surface is reddish-brown, in the $ more yellowish-brown, of the macular bands only the distal border- 

 lines are dark, the bands themselves somewhat darker brown. Very common from Mexico to Southern Brazil. 



37. Genus : iSystasca Edw. 



In its structure very near the preceding genus, but the tooth of the hindwing is shorter, mostly another 

 small one below it, the distal margin below deeper concave, the apex of the forewing somewhat stunted. Tlie 

 slender antennal club is simply bent, the terminal joint of the palj)i longer. 



S. erosa Hbn. (= westermanni Lair.) (176 e). Dark brown, in the (J densely powdered with a erosa. 

 bluish grey; the forewing exhibits 4 white subajjical dots in a straight line, in the $ some more hyaline spots 

 between the median and radial veins and 3 undulate, darker macular bands. Beneath marked the same, 

 but the ground-colour in the ^J is red. in the 9 yellowish-brown. IMexico to" Paraguay.
