WALSH DESCRIPTIONS OF N. AM. HYMENOPTERA. I4I 



by its immaculate black face, black mandibles, immaculate abdo- 

 men, and rufous venter. 



Pimpla CCPlebS, n. sp. — »j". — Differs from the normal inquisitor $ only 

 ^s follows : — I. The whole face, excepting the terminal fovese but includ- 

 ing a short orbit just passing the origin of the antennze, is white. 2. The 

 antennae are full \ as long as the body, the scape white below, the flagel- 

 lum rufous below. 3. The metathorax is rather closely and finely acicu- 

 late up to the two carinse, leaving the space between them, the posterior 

 declivity, and the lower part of the pleura, all highly polibhed. Some- 

 times on the hind edge of the scutel there is a pair of small, obscure, 

 whitish spots, transversely arranged. 4. The ist joint of the abdomen is 

 full \ longer than wide, and its carinse extend nearly to the tip, and are 

 loftier and more acute than in V inquisitor, though the entire joint exactly 

 resembles that of my $ of inquisitor. All the joints immaculate. 5. . . . 

 6. The legs are pale rufous. The 4 front legs with the coxse, both tro- 

 chanters, knees, tibiae, and tarsi, all white. Hind legs with the 2d tro- 

 chanter white ; femora with their extreme tips black; tibiae white, with 

 their 2d and terminal \ black ; tarsi white, with the extreme tips of the 

 joints black. Length c? .30-. 35 inch. Front wing ^ .23-29 inch. 



Two S ; ? unknown to me. But for the white orbits not ex- 

 tending to the occiput, and the absence of the white spot under 

 the front wing, this might be taken for the <? oi vidua $ , n. sp. 

 But in all the numerous cases known to me where the $ in Ich- 

 neumonidce has white orbits and a black face and the d* a white 

 face, the S has orbits as long as those of ? . And there seems 

 scarcely any sexual variation in the 3 typical white spots before 

 and under the front wing. Readily known from my S of inqui- 

 sitor by its white face and clypeus ; and from scriftifrons S by 

 the very short orbits, the absence of the white spot under the front 

 wing, the black metasternum, and the longer ist abdominal joint. 



[This is without doubt the true ^ of inquisitor. Say, as the Entomolo- 

 gical Society possesses specimens of both sexes of the latter species bred 

 from the same cocoon. The ^ correlated with the true $ inquisitor by 

 Mr. Walsh evidently belongs to another species allied to alboricta and 

 indagatrix. — Cresson.] 



Pimpla? Indagatrix, [Walsh, Trans. Am. Ent. See. iii. p. 146.]— ^3'.— 

 Differs from the normal inquisitor only as follows: — i. The antennae are 

 full \ half as long as the body, the xst joint of the flagellum 3 times as long 

 as wide ; the scapus is whitish below, and the extreme base of the flagel- 

 lum is often rufescent. 2. The abdomen has the normal tubercles sub- 

 obsolete and joints 2-to 4 elongate. Joint i is \ narrower at tip than the 

 base of 2, full i longer than wide, and nearly of uniform width except at 

 the extreme base. None of the joints are perceptibly sanguineous at tip.
