(587) 2. Amphigonia simplex (Holland) 

 Episparis simplex Holland, 1S94, Psyche, VII, p. 104, PI. iv, fig. 11. 



One badly damaged specimen taken at. Medje, July 6, 1910. It 

 agrees with the type, with which it has been compared. 



(588) 3. Amphigonia costalis Walker 



Amphigonia costalis Walker, 1865, List Lep. Het. B. M., XXXIII, p. 10.31. 



Four specimens agree aljsolutely with others in the Holland Collec- 

 tion which were compared in 1892 with Walker's type and found to be 

 his species. The examples were all taken at Medje from June to August. 



(589) 4. Amphigonia hyalinata, new species 



Plate XIII, Figure 11, cf 

 cf . Antenna; testaceous; eyes black; verte.x, frons, and palpi pale reddish 

 brown; tegulse, patagia, and upper side of thorax darker reddish brown; upper side 

 of abdomen paler than thorax, and inclining to ashen gray; at the union of the thorax 

 and abdomen on the upper side of the first segment of the latter a number of whitish 

 hairs, presenting the appearance of a lighter colored annulus. Pectus, lower side of 

 thorax, and abdomen pale fawn-color, almost white in certain lights; legs fawn-colored 

 externally, white internally, the tibise of the fore legs marked inwardly with two deep 

 black linear spots. Fore wing on the upper side reddish brown from the base to about 

 the middle, on the outer third plumbeous; crossed by fine transverse lines as follows: 

 a basal outwardly curved line; an irregularly curved median line running obliquely 

 from the inner margin to the end of the cell, which it does not surpass, but in which it 

 displays a retrorse hook-like prolongation; two parallel irregularly curved and crenu- 

 late postmedian lines. The space beyond the outermost of these lines to the margin is 

 uniformly moderately dark plumbeous. On the costa there are five small light spots, 

 the one near the base minute and circular, the remaining four linear. The most con- 

 spicuous marking of the fore wing is a large trapezoidal pale yellowish translucent 

 spot beyond the end of the cell, its longer outline on the costa, the parallel side resting 

 on vein 4. The hind wing on the ujjper side is of the same color and shade as the fore 

 wing. There is a small discal dark dot near the end of the cell, and the two parallel 

 curved postmedian lines of the fore wing are continued on the hind wing, sweeping in 

 a rather even curve to the inner margin, being only inangulated on vein 3. On the 

 under side both wings are pale yellowish white at the base, gradually becoming suf- 

 fused outwardly with brown, which is deepest at the margins. Opposite the cell on 

 the outer margin of the primary is a dark lunulate spot of deeper brown, and the outer- 

 most of the two postmedian dark lines of this wing is reproduced on the lower side 

 by a regularly curved series of blackish spots on the interspaces. On the imder side of 

 the hind wing the tliscal spot is reproduced and the two postmedian bands of the upper 

 surface reappear, being represented by two rows of small dark spots on the interspaces, 

 which are wider apart than the lines on the upper surface. Expanse, 42 mm. 



The type, which is unique, was captured at Stanleyville, August 6, 

 1909, and is depo.sited in The American Museum of Natural History.
