49. Margaronia pratti sp. nov. 



This species comes very close to M. nigripunctata Brem., M. 

 annulata Fabr., and M. warrenalis Swinh. It has the postmedial lines 

 of nig 'Hpunctata, but they are more diffused, and as the white back- 

 ground is less transparent, they are more conspicuous ; the maculae of 

 the fore and hind wings are as in annulata, but the species is bigger and 

 the postmedial lines are less irregular, even more regular than in 

 warrenalis, in which the maculae are also smaller and less conspicuous. 



$ . Thorax, abdomen, wings on upper and under side, antennae 

 and legs pure white, wings with a mother-of-pearl gloss ; palpi with 

 lower half white, upper half and frons ochraceous-orange (xv) ; vertex 

 between the antennae with martius yellow (iv) hairs ; tegulae and 

 patagia ochraceous-orange at base ; femora of fore legs buckthorn- 

 brown (xv), tibia with the same colour on upper and lower thirds and 

 the tarsi suffused with that colour towards end ; two other legs pure 

 white ; third segment of abdomen with two small lateral ochraceous-
