H. aNotes an parasites of the gall-midge (Jatrophobia brasiliensis, Rubs.) of cassava in Trinidad. c1930 ap. 309-313 aIn a field of ground-provisions growing near the Imperial College of Tropical Agriculture at St. Augustine, Trinidad, it was noticed, in November 1928, that the leaves of cassava (Manhiot utilissima, L.), whichformed a large part of the crop, were attackedby a gall-forming insect. Urich (1915, p.39) has recorded a gall-midge (Lasioptera sp.) as occurring in Trinidad, with one or two Hymenopterous parasites, and Bequaert (1926, p.205) states that Felt (1921) report having recceived Cecidomyia manhihot, Felt, from Trinidad (collected by F.W. Urich). The present study was undertaken in connection with Dr. J. G. Myers's investigation, for the Imperial Institute of Entomology, of West Indian insect pests. The writer is indebted to the Imperial College of Tropical Agriculture for laboratory facilities, to Dt. J. G. Myers for advice and criticism, and to Dr. H. F. Barnes and Dr. C. Ferriere for the determination of the midges and their parasites respectively. aLarva aPraga aAprostocetus fidius aManhihot esculenta aParasita tBullitin of Entomological Researchgv. 21, p. 309-313, 1930.
