1885.] MR. H. DRUCE ON NEW HETEROCERA. 519 



dusky white scales : secondaries uniform dark brown, with two blue 

 spots iu the middle of the cell, and just beyond the end of the cell 

 three small white dots ; the tips of the nerves along the outer margin 

 from the apex to near the middle dusky white. The underside the 

 same as above, but the spots are more distinct. Head, thorax, and 

 abdomen brownish black ; legs black ; antennse wanting. 



Expanse 4 inches. 



Hab. N. India, Darjeeling. 



This species is allied to A. euplocoides and A. stelligera : from 

 the former it is at once distinguished by the entire absence of the 

 creamy white of the secondaries ; from the latter by wanting the 

 marginal row of white spots to both wings and being without the blue 

 marginal band. 



Zyg^nid^. 

 Syntomis, Ochs. 

 Syntomis geon, sp. n. (Plate XXXII. fig. 2.) 



Primaries pale chrome-yellow ; the costal apex and outer margin 

 bordered with black, on the inner edge very much dentated ; a black 

 band at the end of the cell joining a small oval-shaped black spot 

 about the middle : secondaries chrome-yellow, narrowly bordered 

 with black on the outer margin. Front of head, collar, and tegula

 Charidea mariamne, sp. n. (Plate XXXII. fig. 3.) 



Primaries deep black, with the basal half brilliant morpho-blue,

 narrow bright orange band : secondaries brilliant blue, broadly

Hab. Colombia, Bogota. 



This beautiful little species is quite unlike any known to me, and 

 it is one of the most brilliantly coloured insects belonging to this 

 genus. 



Mydrodoxa, Butler. 



Mydrodoxa semperi, n. sp. (Plate XXXII. fig. 1.) 



Primaries glossy greenish black, crossed from the costal to the 

 inner margin by a bright metallic golden-yellow band, a row
