locular line and width of ocellar triangle equal; first tergite 
scarcely wider at apex than at spiracles; second more than 
twice as long as wide at apex; others of rapidly decreasing 
length; ovipositor sheath nearly twice as long as first tergite.

Genus MANSA Tosquinet 
Mansa TOSQUINET, Mem. Soc. Ent. Belg. 5 (1896) 209. 
Colganta CAMERON, Ent. 35 (1902) 20. 
This peculiar genus has much in common with the Palearctic 
Megaplectes Foerster. The second joint of the maxillary palpus 
is even larger than in Megaplectes though not triangular; the 
head is of much the same form as that of Megaplectes though 
all of its features are exaggerated, as is frequently found to be 
the case in tropical genera closely related to genera of more 
northern range; the propodeum is similar but shorter and more 
strongly concave; the abdomen is shorter with the apical tergites 
relatively smaller; the venation, except for the unusual shape 
of the areolet, is very similar; and the long calcaria and large 
apical tarsal joints are almost duplicated in Megaplectes. In 
the new allied genus Ceratomansa, described below, the strong 
notauli and sternauli, almost lacking in Mansa, are almost exactly 
as in Megaplectes. 
Seven specimens referable to this genus are at hand. Six 
from the Philippine Islands represent two closely related species,
