G. buccidatricis and G. apantelis have been reared in much larger numbers than the other species, but all f them have occurred more or less abundantly among the hyperparasites obtained from collec- tions of Apanteles cocoons, and combined they are certainly ol major importance in retarding the increase of this *a Fig. 4.—Geli$ bucculatricis, winged male THYSIOTORUS TRIANGULARIS (CRESSOX) (?) This species, which has been doubtfully determined as triangvUaris by Cushman, is merely mentioned here among the hyperparasites attacking A. melanoscelus. It has been reared from only a very few cocoons, and up to this time at least has been of no consequence as an enemy of that parasite. EFHIALTES (ITOPLECTIS) COXQUISITOR (SAY) Two very small male specimens of this species have been reared from cocoons of Apanteles melanoscelus. This parasitism was doubt- less purely accidental and is of no importance, but it is mentioned here because Itoplectis conquisitor has not previously been recorded as having been reared from any species of Apanteles. It is normally primary, being an important parasite of various Lepidoptera, includ- ing such common injurious forms as Malacosoma americana Fab., Cacoecia cerasivorana Fitch, Thyridopteryx ephemeraeformis Haw., and Hemerocampa leucostigma S. & A. Not infrequently, however, it has 33012—27 3.
