Genus MEGATROPIS Muir 



Megatropis obliquefasciata Melichar. 



In the females of this species that I have examined, the second 

 antennal joint has httle or no trace of the prong at its base. The 

 oblique line is sometimes represented by only a dark mark at end 

 of clavus and another on radius.

Megatropis immaculata Muir. 



Megatropis immaculata MuiR, Bull. Hawaiian Sugar Plant. Assoc, 

 Div. Ent. (1913), 12, 58. 



Mindanao, Butuan and Zamboanga (Baker) ; Basilan 

 (Baker). Previously known from Amboina and Borneo from 

 females only; it is possible that M. fiexicornis Muir is the male 

 of M. immaculata. 



In Philippine specimens the second antennal joint of the male 

 varies from the horseshoe form of M. fiexicornis Muir to the M. 

 pallida Muir type with a short prong ; in the female there is no 

 prong, as in M. coccineolinea Muir. 



Megatropis sanguinea sp. nov. 



Male. — Head slightly narrower than in the type species, there- 

 by approaching Nicerta; second joint of antennae with a small 

 knoblike prong at base; gena wide in front of eye, as in M. 

 rubella Muir; the shape of eye approaches that of Leptaleocera. 

 Head, thorax, and abdomen yellowish, heavily tinged with red, 

 which is darkest on dorsal surface, abdomen infuscate. Tegmina 

 deep scarlet, veins darker; wings fuscous with dark veins. 



Ventral edge of pygophor straight, sides slightly arcuate; 

 length of anal segment twice the width, sides slightly arcuate, 

 apex rounded, anus in basal half; styles reaching apex of anal 

 segment, narrow, dorsal edge entire, slightly curved, apex 

 rounded, ventral edge produced into a triangular process in 

 middle. 



Length, 4 millimeters; tegmen, 6. 



Female. — Second antennal joint without a knob or prong at 

 base. Yellow tinged with red. Tegmina yellowish tinged with 

 red ; wings fuscous, veins darker.
