 reflected light ; genital sheath slender, moderately long ; caudal filaments 

 slender, opaque white, equal in length to the thorax and abdomen of the 

 insect ; antenna ten-jointed, with three small knobbed hairs at the apical

Chalcid parasites bred from this insect were determined by Ashmead as 

 Marietta leopardina (Motsch). 



Although I have known of this insect for more than twenty years, and have 

 distributed specimens under the manuscript name of lobaia, no formal descrip- 

 tion of the species has appeared in print until quite recently, when it has been 

 described {loc. cit.) from examples collected in the Philippine Islands. Ceylon 

 examples differ from the type only in the more elongate form of the perforate 

 stigmatic plates. The species occurs in S. India also, where it has been taken 

 on coffee, Thespesia populnea, Michelia champaca and Potigamia glomerata.
