Extract

1. Carabunia myersi is an extraordinarily efficient internal parasite of the nymphs of Clastoptera undulata and Clastoptera sp. in Cuba, and of a third species in the mountains of Haiti.

2. The rate of parasitism is from 65 to nearly 100 per cent.

3. The egg is laid in nymphs of about the second instar, the female wasp negotiating the covering spittle-mass with great ease.

4. There are three larval stadia, and pupation takes place within the indurated larval skin of the last larval instar, inside the abdomen of the still active host.

5. The spiracles of this Hymenopterous puparium achieve connections with certain of the abdominal tracheae of the host and by this means supply air to the pupa.

6. Dissection and experiment showed that Carabunia is not actually, nor is it likely to become, a parasite of froghoppers of the genus Tomaspis (Monecphora) to which the Trinidad cane pest belongs.

I desire especially to thank my wife for assistance in every part of the investigation.
