1920] HoUaml Lepidoplcm of the Congo 305 



fringes are concolorous. There is a faint median band composed of light reddish 

 scales, which is regularly curved, external to which there is a similar but much darker 

 postmedian band, which runs nearly in a straight line from the costa to a point on 

 vein 2, where it turns abruptly inward and upward to the inner margin, terminating 

 there in a small, but very dark brown spot, as does also the median transverse line. 

 There is just above the anal angle a small dark linear spot, located on the inner 

 margin between the anal angle and the dark spot which terminates the postmedian 

 line at its inner extremity. On the lower side both wings are pale stramineous, the 

 fore wing being clouded on the outer margin just below the apex with dark brown 

 scales. The median and postmedian lines reappear on the lower side of the wings, 

 the former being represented by a narrow brown line, the latter on the hind wing by a 

 regular series of deep brown spots one on each interspace, but on the fore wing merely 

 indicated by three similar spots near the costal margin, and one between veins 1 and 2. 

 Expanse, 55 mm. 



The type, which is unique, was taken at Medje, August 24, 1910, 

 and is the property of The American Museum of Natural History. 



When I first examined this specimen I had a feeUng that somewhere 

 or other I had seen a representation of the insect, but after a lengthy and 

 painstaking search I have failed to verify my impression and am forced 

 to the conclusion that it represents an undescribed species. It is nearest 

 to P. preussi Aurivillius.
