determine which would be a labor worthy of a paleontologist, but hardly 

 commendable in the case of an entomologist, who may expect at any 

 time to obtain perfect material for study. 



Lymantriidae 

 Stilpnotia Westwood and Humphreys 



(602) 1. Stilpnotia ogovensis (Holland) 



Redoa ogovensis Holland, 1893, Eat. News, IV, p. 63, PI. in, fig.s. 12, 13. 

 Leucoma nitida Swinhoe, 1903, Trans. Ent. Soc. London, LI, p. 379. 



Two males and one female taken at Medje in June and July. The 

 description of L. nitida Swinhoe shows plainly that it is based upon 

 specimens which have the characteristics which caused me to separate 

 the species from luteipes Walker, namely ''fore wings with a beautiful 

 silvery sheen, with thin longitudinal curved waves in certain lights, etc." 

 The specimens have been compared with the types in my collection, 

 with which they agree absolutely; the specimen in the Druce Collection 

 of which Swinhoe speaks was a male of S. luteipes inadvertently sent 

 Druce as R. ogovensis, the males of the two species having been carelessly 

 mixed. 



Naroma Walker 



(603) 1. Naroma signifera Walker 

 Naroma signifera Walker, 1856, List Lep. Het. R. M., VH, p. 1744. 



One badly worn female specimen taken at Niangara, December 9, 

 1910. The signa, consisting of a circlet of black raised scales in the cell 

 of the fore Aving, are rubbed off in the specimen, but traces of them may 

 be seen with a glass. 



Stracena Swinhoe 



(604) 1. Stracena species (?) 



A single worn specimen allied to the species to which I apphed the 

 name promelcena but not identical with it, as shown by the type, nor 

 with fuscivena Swinhoe, of which we have good specimens. The speci- 

 men is, however, too poor to permit me to found a new species upon it. 

 It was taken at Medje in July. 



Sapelia Swinhoe 



(605) 1 . Sapelia bipunctata, new species 



Plate XIV: Figure 3, d'; Figure 4, 9 

 cf . White throughout, except that the frons, the pectus and the legs are yel- 

 lowish, and that at the end of the cell of the primaries there are two minute black dots,
