Ipobracon peronatus, Cam.

Iphiaulax peronatus, Cameron, Biol. Cent.-Amer., Hym., i, 1887, p. 337.

Trinidad : 3 ♀♀, 25.xi.1928, 5.xii.l928, 21.ii.1929 (J. G. Myers).

Host. Dr. Myers considers this parasite to be associated with the Cerambycid beetle, Stirastoma depressum, L., infesting cacao logs.

These specimens agree absolutely with the type (which is in the British Museum) with the possible exception that they appear to have the 2nd cubital cell relatively somewhat longer ; this difference, however, is so minute that it is a character upon which I am not prepared to describe a new species.

Ipobracon peronatus is easily separable from the two other recorded Braconine parasites of Stirastoma, as follows : From Cyanopterus depressi, Vier., by the thorax and legs, the colour of which in this latter species is black throughout ; and from Cyanopterus steirastomae, Vier., by the nature of the 2nd tergite, which from Viereck's description would appear to be fine and smooth.
