Distribution in the United States. This species is stated by Dr Riley to occur in the more southern portions of the middle states and in the southern states, though it appears to be absent from the peninsula of Florida. It occurs within these limits from the Atlantic to Texas and reaches the less timbered regions west of the Mississippi. Professor Webster has recently shown that this insect has established itself in Ohio within 25 miles of Lake Fig. 18 Pimp I a i n q u i s i t o r : <i~full grown summer larva ; *=liiber nating larva; (T^mouth parts of larva; rt'^adult female; f=abdomen of male from side —all enlarged ; i-greatly enlarged. (After Howard. Dep't Agric. Div. Ent. Tech. Ser. 5. iSg;) Natural enemies. This species is subject to attack by several natural enemies. P i m p 1 a inquisitor Say, P. conquisitor Say, and H e m i t e 1 e s t h y r i d o p t e r i g i s Riley, are among the more important ichneumon parasites. The last named is more abundant than the two preceding, and unfortunately, it is probably a hyperparasite preying on the beneficial Pimplas. Chalcis ovata Say is a ininute, four winged fly which was reared from this species by Dr Lintner. Dibrachys.
