Cryptoloba rivularia, sp. n. 



Primaries black, traversed by four white lines ; the first is 

 not well defined, the second is serrated and sharply dentate 

 above inner margin, the third is serrated and angled below 

 costa, the fourth is macular below costa. Secondaries white, 

 clouded with blackish at the base and on outer margin ; 

 discal spot is black, and there are indications of a blackish 

 central band. Fringes of primaries black and white ; of 

 secondaries white, preceded by a black line. Under surface 

 white ; primaries have the costa streaked with black from 

 base to a short angulated band ; the outer margin is broadly 

 black, intersected by a white macular line ; secondaries have 

 a black discal spot, interrupted central band, and outer mar- 

 ginal border, the latter intersected by a white macular line.

 Lobogonia paralldaria y sp. n. 



Pale brown, irrorated with darker, especially on the second- 

 aries. Primaries traversed by two oblique, parallel, dark 

 brown lines, each of which expands on the costa; there 

 is a dark brown spot on costa before apex, and one below 

 between veins 5 and 6 ; fringes almost black, except at 

 the angle. Secondaries have a discal dot and sharply-curved 

 transverse line, both dusky ; fringes ochreous, preceded by 

 a dark brown line. Under surface : of primaries smoky grey, 

 costa and on outer margin ochreous ; of secondaries ochreous, 

 irrorated with brownish; markings on all wings similar to 

 above, but the first line of primaries is less, and that of 

 secondaries more, distinct.
