Tribe Protickneumonini Figure 36a Coelichneumon pepticus (Cresson) (fig. 36a) and Protichneumon sp.(GCV) were examined. There are no clear characters differentiating this tribe from theIchneumonini. The head parts are heavily sclerotized and there is alarge sclerotized area of the cranium lateral to each pleurostoma. InCoelichneumon the ocular line (shown by the antenna in fig. 36a) iswell sclerotized and conspicuous. It is also conspicuous in Protich-neumon. The specimen of Protichneumon was not figured since thelabral setae and sensilla were not clearly visible on the preparation;however, their arrangement appeared to be similar to those of Coelich-neumon.

This speciesdiffers from other Ichneumonines examined in that the hypostoma issharply bent.
