as that quoted above. It is a long time, since 187G, for my 

 species to have remained unknown to one of the chief workers 

 at the lepidopterous fauna of the dark continent ; in twenty- 

 seven years surely he should have gained some idea of the 

 identity of a species the type of which he might have 

 examined at the Museum on more than one fairly long visit 

 to London.

Subfam. II. Bactriciinm. 



I am obliged to form a new subfamily for my genus Bac- 

 tricia ( = Scaphegyna, Karsch), which agrees with the 

 Lonchodina3 in its long antennas and in the short median 

 segment, but differs entirely in the large incurved cerci of 

 the male and in the long operculum of the female. 



The two known species are from Africa, and I now add 

 one from Singapore. (By some error the name of this sub- 

 family has been given as Bacteriinge in the list on p. 372 

 an tea.) 



Genus Bactricia, Kirb. 



Bactricia Ridley i, sp. n. 



Male. — Greenish brown ; head short, narrowed behind, and 

 with two compressed obtuse horns between the eyes; space 

 between the horns and the antennae, sides of head, (probably) 

 the propectus, and a lateral streak below the median segment 

 white. Antennae and legs long and slender, the latter nearly 

 straight, and unarmed except for a sharp, flattened, curved 

 tooth near the base of the middle femora beneath. Median 

 segment half as long again as broad • abdominal segments 

 2-6 about three times as long as the median segment, the 

 seventh about twice as long ; segments 8 and 9 about as 

 long, tenth rather shorter, concave at the extremity ; cerci 

 compressed, almost spatulate, incurved and crossed ; oper- 

 culum extending as far as the ninth abdominal segment.
