Grenus Peocalypta, n. gen. 



Primaries very elongate, with hyaline spots, costal margin undu- 

 lated ; the second and third median branches and the lower 

 radial emitted close together at end of cell, and far distant 

 from the first median branch ; secondaries subtriangular, apical 

 half of costal margin excavated ; subcostal vein with two 

 branches, forking oft' from anterior extremity of discoidal cell ; 

 discocellulars strongly angulated, separated by the false ner- 

 vure, which runs through the cell to near the base of the median 

 nervure ; median nervure with three branches, the first emitted 

 before the end of cell, the second and third emitted together at 

 lower extremity of cell. Type P. suhcyanea, Walker.

Grenus Pteetgopterus, n. gen. PI. XXIX. fig. 10. 



Allied to the preceding genus, and to Antichloris ; wings opaque ; 

 secondaries with the anal angle distinctly caudate, and both 

 inner and outer mai'gins slightly excavated, the veins nearly as 

 in the preceding genus, but the front of the cell projecting for- 

 ward, so shortening the subcostal branches and lengthening 

 the upper discocellular ; the false radial also forking from the 

 centre to tlie apex of second subcostal branch (this may, how- 

 ever, be a natural wing-fold). Type P. clavipemiis, n. sp. 



1. Pterygopterus clavipennis, n. sp. 



Body dark brown ; frons, the palpi in some lights, crest, a few scales at 

 back of head and at anterior margin of pi'othorax, a spot on the 

 shoulders, a longitudinal litura on metathorax, the lateral drum-like 

 expansions and an interrupted line along each side of the abdomen 

 metallic green ; antennse black, tipped with orange; primaries with 

 the costal half dark sericeous olive-green, purplish at its borders, 

 with the veins at base, aad the median vein between its branches
