before apex. Lateral margins of pygofer acutely angularly 

 produced. Genital styles broad at base, narrowing to apex, 

 inner margin convex, outer margin convex on basal half, 

 concave on apical half, at the apex there is a small process 

 at right angles to the apex. 



Sc with three branches; R with three; Mi and 2, 3 and 4, 

 4a; C'mi, la ; a cross-vciu in clavus near base between first 

 claval and suture ; very few granules in cells. Mesonotum 

 with five very obscure carinse ; vertex without any transverse 

 or oblique carinse ; clypeus without a median carina. There 

 is a specimen marked " var." in the type-material which I 

 consider to be the female. In it the pygofer is wider than 

 long ; the anal segment is missing ; the ovipositor is as long 

 as the pygofer or slightly longer. 



Mnemosyne philippi7ia^ Stal. 



The type is a female. It has no median carina on clypeus ; 

 vertex with small oblique carinse at apex, the mesonotum 

 with five distinct carinse. Anal segment longer than wide, 

 narrow. Pygofer wider than long; ovipositor slightly 

 longer than pygofer ; pregenital plate truncate on posterior 

 margin. There is a male specimen from Darjeeling, India, 

 with the type-material which represents a distinct species. 



I have two female specimens from Surigao, Mindanao 

 {^Baker, no. 17525). 



Mnemosyne planiceps (Fabr.). 



I have one male specimen from Central America which 

 agrees with specimens in the British Museum identified as 

 planiceps. 



The median carinse on frons and clypeus and three meso- 

 notal carinse distinct. The pygofer compressed, lateral 

 margin produced angularly with a small emargination near 

 the anal angle ; medio- ventral process wider than long, sub- 

 quadrate and produced into a little point in the middle of 

 apical margin. Anal segment long, thin, tubular with the 

 anus at apex, below the anus the apical margin produced 

 into a large spine at right angles to anal segment and a little 

 longer than half its length. Genital styles boomerang- 

 shape, widest on basal half, apex narrow, truncate, inner 

 margin concave, outer margin convex. Periandrium long, 

 slender, subtubular with a spine arising from base laying 

 alongside and about half the length of periandrium ; penis 

 represented by two small membranes at apex. The perian- 

 drium is amalgamated to the apodeme of the penis.
