Distribution: Ceylon, India, Philippine Is, 



Food: Bred from a mantid egg-mass (India). 



Material examined: Luzon, Mt. Makiling (Baker), "30," "Monopis 

 prosarithma Meyr., Paratype" (1 9) : 2 9; Los Banos, 2 cf^, 1 9, genit. 

 slide 5283 cf (USNM). Agoo, La Union, 10.VIII.1945 (J.G. Francle- 

 mont), 1 9, genit. slide 5104. 2 cf , 4 9 (GUI). 



The present topotypical material from Mt. Makiling proves the 

 above synonymy. M. prosarithma was described after a single female 

 (type apparently lost) , which differed by the neuration of the forewing 

 (veins 7 and 8 long-stalked, 9 separate) and by grey ciUa of the hind- 

 wings. I find these veins in all the present specimens coincident (vein 

 7 or 8 absent), while one female has also yeUow cilia in the hindwing. 



Female genitalia: Sterigma weak, a slender and small flattened 

 funnel, with a deeply emarginate ventral edge. Ductus and corpus 

 bursae membranous. Signum absent. Lobi anales long-pointed. 

 Anapophyses pointed at top and slightly sinuate. Both pau-s of 

 apophyses slightly and abruptly dilated at base. 



Male genitalia: Tegumen and gnathos together forming a sclero- 

 tized tube. Uncus weU defined, top with two small subascending 

 processes. Hook of gnathos bipartite, halves pointed, rather short, 

 sclerotized and united. Vinculum, a slender ring with prominent 

 lateral angles. Saccus very long and slender, gently dilated beyond 

 base. Valva much larger than in M. monachella, robust, subrectangu- 

 lar, cucullus slightly dilated, truncate; with inner edge forming an 

 elevated obtuse ridge along its entire length. Aedeagus long, slender, 

 spindle-shaped in middle, base dilated.
