HERMINIID^. 



BocANA, Walk. 

 58. Bocana sypnoides, n. s. 

 5 . Aspect of many species of Sypna ; primaries purplish 

 brown, almost black ; an ill-defined dentated black line across the 

 basal fourth ; reniform spot angular, golden testaceous, enclosing a 

 black litura ; two parallel widely sinuated and dentated externally 

 pale-edged black discal lines, the external dentations dotted with 

 whitish at their apices ; a black marginal line dotted with pale 

 ochreous ; fringe blackish, varied along its outer edge with whitish ; 

 secondaries smoky brown ; two internally diffused blackish stripes 

 from abdominal margin, not reaching the costa, dentated and 

 partly edged with whitish externally; a marginal series of pale 

 ochreous dots ; fringe spotted at the base with blackish ; thorax 

 dark purplish brown, the head and collar blackish ; abdomen dark 

 smoky brown, slightly paler at the sides and base ; wings below 

 smoky brown, crossed by two darker diffused discal stripes, the 

 outer one with pale external border ; a sprinkling of whitish scales 

 on the costal areas ; a slender blackish marginal line, interrupted 

 at the extremities of the veins by testaceous dots ; secondaries 

 with a blackish disco-cellular litura ; palpi dark brown, the scales 

 on the inner surface tipped with ochreous; body below smoky 

 brown, the legs dark brown, with ochreous spots at the extremities 

 of the joints. Expanse of wings, 42 mm. 



Viti Islands. 



Allied to B. manifestalis, which ranges from Ceylon to 

 Fiji. 



LOPHOCOLEUS, n. g. 



Form and iieuration almost exactly as in Edesscna, from which 

 genus it is, however, at once distinguished by the long tapering 

 broadly pectinated antennte, in which character it agrees with 

 Bocana ; from the latter it differs in form of wing, and from both 

 genera in the broad flattened and coarsely scaled palpi and the 

 structure of the front legs, the femora being armed at their distal 

 extremity by a strong curved process thicker than the tibia, and 

 extending almost to the extremity of the tarsus, its lower surface 

 clothed with long silky hairs ; thus, at first sight, the leg appears 

 to be double from the knee-joint. 



59. LopUocolcus mirahilis, n. s. 

 (J . Primaries above dark smoky brown ; the two ordinary 

 lines indistinct, that at basal third represented by an unequally
