" The RiNQ-LEaoED Pimpla (Pimpla annullpes, Br). 



" This is a black fly, varying considerably in size, the female 

 sometimes measuring but ^, at others fully i inch exclusive 

 of ovipositor ; the male somewhat smaller. The genua 

 Pimpla was briefly characterized in my last report, p. 43, 

 where it was shown that this same species attacks the walnut 

 care bearer {Acrobasis juglatulis, LeB). I annex a lateral 

 outline of a female Pimpla, Fig. 38, the male has a more 

 slender abdomen which is unarmed. 



"Pimpla Annulipes is black: the abdomen rough 

 punctured above, with the borders of the joints polished and 

 inclined to brown. The tegulae are white, and the legs are 

 '\ reddish, with the exce|)tion of the middle and hind tibiae, 

 j which are dusky — especially the hind pair — and have a broad 

 ■' white annulus, sometimes indistinct on the middle pair. The 

 posterior tarsi are dusky, especially at tip. The palpi are pale yellow. Cresson says it may 

 be distinguished from the other species of the genus, by the scutellum being black, the tegulse 

 while, and the anterior coxae yellowish red. 



" This fly eats its way through the chrysalis and the cocoon of the Codling Moth, with- 

 out having previously made any cocoon of its own. It was quite abundant last ."^ummer as 

 from one lot of Carpncapsa cocc ons, I obtained 21 parasites — all of them females but one. It 

 is a widely distributed and common species. The second parasite may be called the 



" Delicate Long-sting {MiKrocenirus delicatus, Cres). 



" It has recently been described by Mr. E. T. Cresson (Trans. Am. Ent. Soc. iv., p. 178), 

 and is a somewhat variable species, occurring throughout the Eastern, Middle and Western, 

 States, and in Mexico. 1 subjoin a description drawn up from my bred specimen,s. 



" M»le. Length 0-2.5; expanse 045 ; inch. 

 iSlender, colour pale, polished, honey yellow ; 

 uniformly and sparsely pubescent ; tinged with 

 brown superiorly, thebasal joint of abdomen and 

 a medio-dorsal line on the other joints being 

 quite brown. Head, with the eyes (except at 

 disc), and a spot between ocelli, brown-black ; 

 palpi long and almost white :antcnnai one-fourth 

 longer than the whole body, about 48 joints, ex- 

 olusive of bulbus, curled at tip, the ends of basal 

 joints and the whole of joints dusky. Thorax, 

 with the sutures well defined, and two .small 

 triangular black spots behind front tegulae, 

 the motathorax strongly trilobed ; legs very 

 long, pale honey yellow, with tips of tibiae and 

 tarsi faintly dusky ; wings yellowish, hyaline 

 and iridescent, with the veins iuteous, and the 

 stigma pale honey yellow. 



'• Female. Rather larger and with the 

 abdomen somewhat paler, otherwise similarly 

 marked. Ovipositor yellow, J longer than body, 

 the sheaths quite pilose, and inclining to fus- 

 scou. Described from 2 females and 1 male. 



" It is a graceful fly with very long an- 

 tennae and legs, and the female with a long 

 ovipositor Fig. 39, " (the hair lines at the side 

 . of the- flgure show the natural size of the fly)." 

 The colour is pale houcy yellow inclining to brown above. The unfortunate apple-worm is 

 probably pierced while yet in the fruit, as it always succumbs soon after forming its cocoon,
