TWO TEXT FIGURES 
This paper contains descriptions of new diapriids, bethylids, 
and braconids from the Philippine Islands, Borneo, and Singa- 
pore. The specimens studied in writing the descriptions were 
Sent to the United States National Museum by Prof. C. F. Baker. 
Thanks are due and here recorded to Mr. 8. A. Rohwer for 
permission to study Professor Baker’s material, and to Miss 
Eleanor Armstrong for drawing the head of the new species 
Loboscelidia maculipennis. The other drawings were made by 
me. 
DIAPRITDAE 
Genus LOBOSCELIDIA Westwood 
Westwood founded this genus on a single species, L. rufescens 
Westwood, from Sulu Island, southwest of Mindanao, Philippine 
Islands. Kieffer has described two new ones in his recent 
monograph of the family Diapriide. 
All the species, including those described in this paper, are 
from the islands southeast of Asia. Loboscelidia defecta Kieffer 
occurs both in Borneo and in Singapore if my identification is 
correct. Its type locality is Palawan Island of the Philippine 
group. 
It seems probable that these wasps are myrmecophilous. 
They have somewhat the habitus of ants and the woolly appear- 
ance of the neck is characteristic of many myrmecophiles. 
Key to the species of Loboscelidia Westwood.
