PsiMAUA, Walk. 



53. P. Africaiia, sp. nov. (J. Upper side 

 of thorax and abdomen fuscous, lower side 

 paler, covered in part with whitish hairs. 

 The primaries on the upper side are slaty- 

 brown, crossed b3' obscure transverse lines 

 and marked on the costa before the apex bv a 

 dark brown subtriangular spot, the apex of 

 which pointing inwardly is obtuse, or 

 rounded, and the outer margin defined by a 

 very fine whitish line. The secondaries are 

 of the same color as the primaries marked by 

 a few scattered submarginal dark brown spots, 

 and above the anal angle on the inner margin 

 by a curved brown line. On the under side 

 both wings are paler than on the upper side, 

 especially at the base. Both have a pale 

 discal spot at the end of the cell ; both are 

 crossed beyond the cell fn- an irregularly 

 curved and acutely zigzagged transverse 

 limbal line, followed by a submarginal 

 curved series of pale spots. Expanse, 40 mm. 



54. P. iinperatrix. sp. nov. $. Some- 

 what larger than the previous species, and 

 with the outer margin of the primaries 

 strongly jiroduced, or angulated, at the 

 extremity of the third median nervule. The 

 upper side of the body is ashy-brown. The 

 lower side is paler, grayish. The primaries 

 upon the upper side are hoary brown cros.^ed 

 by numerous more or less obscure dark lines 

 and series of spots. On the costa before the 

 apex is a large dark brown triangular spot, 

 from the lower or apical end of which several 

 small spots, gradually diminishing in size, 

 extend in a series in the direction of the outer 

 angle. Beyond these spots below the apex 

 is a curved brown shade running from the 

 large triangular brown spot to the outer 

 margin at its middle. The secondaries are 

 colored like the primaries above. The middle 

 of the wing is crossed by a series of fine 

 subhastale brown maikings, shaded out- 

 wardly by olivaceous-gray, and succeeded by 

 a similar submarginal series nl heavier spots, 

 which are most conspicufius on the inner 



margin near the anal angle. The margins of 

 both wings are marked upon the interspaces 

 by minute dark brown transverse dashes. 

 On the under side, both wings are fuscous 

 with their inner margins and the apex of the 

 primaries grayish. Both are crossed by 

 obscure transverse median, limbal, and sub- 

 marginal lines composed of subhastate mark- 

 ings, which are bordered externally by paler 

 lines and spots inclining to ochraceous. The 

 submarginal series is the heaviest and most 

 conspicuous, the apical extremity on the 

 primaries being broad, and the pale spots 

 being succeeded externally by darker lines, 

 so that they appear as a central bar of light 

 spots upon a broad darker band. Expanse, 

 47 mm. 



DY.SGONIA, Hiibn. 



55. D. ueptuiiia, sp. nov. J. Closely 

 allied to D. joviana^ Ciam., and D. arcuata, 

 Moore, from the former of which it dift'ers in 

 having the outer margin of the median dark 

 band evenly curved and not excised in the 

 region of the median nervules. and from the 

 latter it differs in haying the median band 

 much wider and the sub-basal transverse band 

 very slightly bowed out toward the margin 

 below the cell. D. joviana is found on the 

 western coast of Africa and is represented in 

 my collection. Its facies differs positively 

 from that of this species. The present 

 species is furthermore considerably larger 

 than D. joviana. The differences between 

 this species and the other species described 

 in this paper are most clearly illustrated by 

 the figures on the plates accompanying this 

 article. It is exceedingly difficult among 

 these forms, which are closely allied and yet 

 distinct, to define \vith words the differences, 

 which consist mainly in the size and in the 

 outline of the transverse bands of the prima- 

 ries. Expanse, 43 mm. 



^6. D. -pliitoiiia, sp. nov. J. Allied to 

 the preceding species, from which it dift'ers 

 in having the dark median band on its inter-
