SOME NEW PARASITIC HYMENOPTERA FROM 

 BRAZIL. I 



By Charles T. Brues. 



In a previous publication,- I have dealt with part of a very 

 interesting collection of Parasitic Hymenoptera obtained by the 

 Stanford Expedition to Brazil. Only the Ichneumonidse and 

 Braconidae were included in the first paper, and the present one 

 contains descriptions of a number of new species belonging to other 

 families. There are many other species, especially in the super- 

 family Chalcidoidea which it has seemed inadvisable to consider at 

 the present time, mainly on account of the great difficulty experi- 

 enced in recognizing with certainty many of the species described 

 by early writers. Descriptions of eleven new species and one new 

 genus are given below while thirty-one new species and three new 

 genera were included in the previous report.

9. Length 14 mm.; ovipositor 16 mm.; wing 8.5 mm. Black; head and base 

 of antennje bright ferruginous; four anterior legs more or less fuscous; tip of hind 

 tibiiE and hind metatarsus fulvous; ovipositor with a subapical white annulus. 

 Head above transversely aciculate, the aciculations between the ocelli curving 

 forward and forming a series of bowed lines enclosed in a shield-shaped margined 

 area that has its anterior angles tuberculate; on each side of the median ocellus 

 is another tubercle which form an equilateral triangle with a third median one below 

 the ocellus. Face with somewhat irregular transverse aciculations below; above, 

 the aciculations curve upwards laterally passing from the median to the lateral
