Lomadonta, gen. nov. 



Allied to the preceding genus, from which 

 it differs principally in the form of the prima- 

 ries, which have the apex acute, the outer 

 margin straight but sharply produced at the 

 extremity of the third median nervule. 



75. L. erythrina, sp. nov. £. Palpi 

 white. Front and upper side of thorax pale 

 reddish-fawn. Abdomen pale reddish with a 

 dorsal line of darker markings. The under 

 side of the thorax and abdomen with the 

 legs are whitish. The primaries are pale yel- 

 low, with the costa and a broad subapical 

 transverse band, running from the costa to 

 the outer margin at its toothed projection, 

 fawn color, defined outwardly and inwardly 

 by darker lines. Below this band between 

 the first and second median nervules, there is 

 a large oval silvery spot defined inwardly by 

 dark brown, and the remaining portions of 

 the wing are traversed by parallel undulating 

 red lines. The secondaries are white, shad- 

 ing upon the costa and outer margin into 

 yellowish, with the fringe near the anal angle 

 brown. The under side of both wings is 

 white. The apex of the primaries is tipped 

 with yellow, preceded by the broad band of 

 the upper side, which reappears on this side 

 more obscurely. Both primaries and second- 

 aries have an obscure discocellular dot. 



2 ■ Marked like the male but with the broad 

 subapical band on the primaries obsolete. 

 The dorsal line of dark spots is most con- 

 spicuous in this sex. Expanse, J, 33 mm.; 

 $ , 36 mm. 



Artaxa, Walk. 



76. A- nigra, sp. nov. $. Antennae pale 

 fawn. Palpi, front, and upper side of thorax 

 of the same color. The upper side of the 

 abdomen near the thorax is fawn color 

 shading into dark brown near the extremity. 

 The under side of the body and the legs are 

 pale fawn. The primaries and secondaries 

 are uniformly smoky-brown, or blackish, 



with the fringes slightly paler, and a few 

 fawn colored hairs at the base of the wings. 

 On the primaries, there are two or three coal- 

 black subapical spots. On the under side, 

 the wings are lighter than on the upper side, 

 with the bases and the margins pale fawn. 

 Expanse, 32 mm. 



This well marked species is represented by 

 specimens taken at Lake Onanga. 



77. A. mcsomelaena, sp. nov. £. Front 

 ochraceous. Antennae whitish with darker 

 pectinations. Body dark brown above, whit- 

 ish below. Legs concolorous. The wings 

 on the upper side are pale cream-buff. The 

 primaries are traversed on the middle by a 

 broad black band, divided into spots by the 

 neurations. which are whitish. There is a 

 submarginal line of faint light brown mark- 

 ings common to both wings. The under 

 side of both wings is pale cream-buff with 

 the basal area of the primaries shaded with 

 pale brown, and a submarginal line of the 

 same color on both wings. Expanse, 15 mm. 



78. A. tessellata, sp. nov. J. Palpi, 

 front, and thorax rufous. Abdomen brownish 

 with a dorsal row r of upright tufts of blackish 

 hairs. There are six of these tufts about one 

 millimetre in height. The under side of the 

 body and the legs are pale yellowish. The 

 primaries are ochraceous with the middle 

 area clouded with black, and with a limbal 

 band running from before the costa parallel 

 to the outer margin to the middle of the 

 inner margin. These black bands are broken 

 on all the nerves which they cross, the nerves 

 being of the prevalent ochraceous ground- 

 color. The secondaries are uniformly sooty- 

 brown with the fringes pale ochraceous. 

 There is a black discal dot at the end of the 

 cell of the secondaries. On the under side, 

 the primaries are sooty-brown with the costa 

 and the margins pale buff. The secondaries 

 are pale buff with a large discal dot and a 

 curved median brown line and a few obscure 

 submarginal shadings. Expanse, 25 mm.
