1920] Holland, Lepidoptcra of the Congo 281 



an irregular dark line, defined outwardly by a paler line, bounding a light postmedian 

 area which extends as an irregular band from the costa to the inner area, but is inter- 

 rupted just beyond the reniform at the end of the cell by a dark brown quadrate 

 blotch. This transverse band is bounded externally by an irregularly curved post- 

 median line running from a point about 3 mm. behind the apex almost directly to 

 vein 2, where it turns outwardlj- and terminates on the inner margin about 2 mm. from 

 the tornus. This line constitutes the inner boundary of the dark external margin of 

 the wing, and is defined inwardly by a few light scales. The fringes are separated 

 from the body of the wing by an exceedingly fine black marginal line, the interspaces 

 being punctated by very minute white dots, more distinct toward the tornus. On 

 the upper side the hind wings toward the outer margin are sooty, paler toward the 

 base; the fringes concolorous. On the under side both wings are prevalently tawny 

 ochraceous sprinkled with very small brown dots; the fore wing has a whitish point 

 near the base; a larger whitish spot corresponding to the reniform in its location, 

 punctated above by a black dot. Beyond this light spot the dark blotch which 

 appears on the upper side is faintly reproduced on the lower side, and externally 

 is continued to the costa by a fine evenly curved dark line; the lower portion of the 

 cell and the area included by the interspaces from the inner margin as far upward 

 as vein 7 are fuliginous, except on the outer border, which is lighter. There is a small 

 blackish dot between veins 7 and 8 behind the apex. The hind wing on the lower side 

 is colored like the fore wing. There is a small black dot at the end of the cell, followed 

 by an irregularly curved fine dark brown line; a dark subterminal fuliginous band 

 runs from the upper angle toward the anal angle, which it does not quite reach. The 

 anal angle and the inner margin are pale stramineous; the outer border is pale fuscous 

 irrorated with brown, the division between the subterminal dark band and the outer 

 area of the wing being marked by an irregularly curved row of light spots. In the 

 cotype the dark subterminal band is not as heavy as in the type and is more or less 

 broken up into small salt-and-pepper dots. Expanse, 43 mm. 



The species is represented in the collection by two specimens, the 

 type taken at Bolengi, July 20, 1909, and deposited in I'he American 

 Museum of Natural History; the paratype taken at Poko, July 19, 

 1913, and reserved for the Holland Collection in the Carnegie Museum. 



Ercheia Walker 

 (559) 1. Ercheia subsignata (Walker) 



Achosa subsignata Walker, 1865, List Lep. Het. B. M., XXXIII, p. 959. Holland, 

 1894, Psyche, VII, PI. ii, fig. 9. 



There is one rubbed female specimen of this species which on the 

 under side (the upper side is too badly rubbed to be well identified) 

 agrees absolutely with specimens originally compared with Walker's 

 types and in my collection. The insect was captured at Gamangui 

 on Jime 27, 1910. 



Hampson, in his 'Catalogue of the Phalaense,' XII, p. 495, sinks 

 Ercheia periploca Holland as a synonym of E. subsignata (Walker) . 

 Hampson may be right, though the two insects look wonderful^ distinct.
