"80 MR. H. DRUCK ON NEW HETEROCERA. [DeC. 19, 



thorax spotted with black. Abdomen yellow above, black on the 

 underside. 



Expanse 2^ inches. 



JIab. East Africa, Nyassa ( Thelwall). 



This beautiful species is allied to H. bellatrix, Dalman, from 

 South Africa. 



Fam. NYCTEMERID.E. 

 Nyctemera, Hubner. 

 Nyctemera acR/Eina, n. sp. 



Primaries dusky brown ; the nerves all black, except on the white 

 band which crosses the wings from about tlie middle of the costal 

 margin nearly to the anal angle. Secondaries — the basal half pure 

 white, the outer half yellowish brown, shading to dark brown on the 

 costal margin. Antennae black. Head, thorax, and upperside of 

 abdomen brown ; underside yellow. 



Expanse 3 inches. 



Hub. West Africa, Calabar. 



I at first thought that this species would be better placed in the 

 genus Metis; but on comparing the nenratinn with specimens of 

 Nyctemera opicafis which 1 have had mounted in Canada balsam, I 

 find that it is the same. This and the following species are the 

 two largest described in this genus. At first sight they might easily 

 be taken for Acreece. 



Nyctemera chromis, n.sp. (Plate LXI. fig. 2.) 



Closely allied to the preceding species. The primaries the same, 

 Gidy slightly more yellow. Secondaries chrome-yellow, shading 

 to pale brown on the outer margin. Underside the same as 

 above. Head and thorax black. Abdomen brown above ; underside 

 yellow. 



Expanse 2f inches. 



Hab. West Africa {Thomson).

 Otroeda varun^a, n. sp. 



Primaries pale chrome-yellow, partly crossed by two black bands, 

 broadest on the costal margin, tapering to a point near the anal 

 angle ; apex broadly black ; a submarginal row of five white spots, 

 the first two the largest. Secondaries pale chrome-yellow, the 

 outer margin black, with a submarginal row of white spots. Under- 

 side the same as above. Head black. Tborax and abdomen 

 yellow. 



Expanse 2^ inches.

This species is allied to Otroeda vesperirM of Walker. It is a 

 much smaller and more pale-coloured insect.
