 depressed silvery pile, the pile on the pygidium tinged with rufo-fulvous and it is sparsely 

 covered with short blackish hairs. Wings hyaline, tinged with yellow, the apex tinged with

 following 2 united, the 2Dd about one quarter shorter than the ■£&; the 2 nd récurrent nervure 

 received near the apex of the basai third of the cellule ; the space between the 2 récurrent 

 nervures is about one fourth less than the 2 nd abscissa of the radius. Eyes above separated 

 by the length of the 4 th antennal joint, which is about the length of the 3 rd . Ç.

The parasitic Hymenoptera taken by Mr. LORENTZ are very interesting. The larger 

 Pimplinae are well represented, including 3 species of Certonotns, an Australian form, at any 

 rate it has not yet been found in the Hindu Malay Islands or India. The fine Pimplid genus 

 Erythropimpla, of which 3 species hâve been found, extends as far north as the Khasia Hills 

 in Assam is found also in Hindu-China. Xanthopimpla is probably a common Papuan genus. 

 Many yellow Pimplae hâve been described by SMITH from the Austro- Malay, as well as from 

 the Hindu Malay Islands, but so badly, shortly and without any mention of the important
