HYMENOPTEROUS PARASITES. 1907 



reared, and as it may prove to be a species found in New England, tlie de- 

 scription of the parasite is here quoted : — 



Apanteles theclae : length 2 mm. $ . $ black ; palpi white ; labrum, mandibles, and 

 sometimes the antennae, piceous ; tibiae and tars! testaceous, the apical lialf of poste- 

 rior tibiae and the posterior tarsi blackish. Wings hyaline; the tegulae, stigma, 

 costa, beyond stigma, and the radius and veins at base of areolet, piceous. Antennae 

 of the female much shorter than the body, of the male nearly as long as the body. 

 Mesothorax closely punctured, opaque; metathorax not truncate, finely rngose- 

 reticulate, and with a slight median, longitudinal ridge. Two basal joints of the abdo- 

 men with numerous distinct punctures ; remaining joints often sparsely punctate ; basal 

 joint with the lateral margins narrow; ovipositor not exserted. Stigma short, trian- 

 gular, radius descending from its middle and uniting at a considerable angle with the 

 basal vein of the areolet. 



12. Apanteles janoniae n. sp. 



Parasitic on Junonia coenia. 



Length of body (J, 2.6 mm. Color black. Punctation of head, thorax and scutel- 

 lum dense, coarsest on thorax, very dense, fine and somewhat confluent on the head. 

 Head with facial ridge not very distinct, though there is a slight, smooth projection 

 close to and in front of the antennae ; (palpi wanting) eyes brown ; antennae black ; 

 the first joint and flagellum brownish beneath. Thorax with a slight median carina on 

 posterior third of mesoscutura ; fovea of postscutellum minute ; metascutellum 

 rugose, without median carina, its lateral carinae strongly angulated; tegulae honey- 

 yellow : wings normal ; costa brown, stigma yellowish brown, veins very pale yellow- 

 ish : legs brownish-yellow, with all coxae black and posterior femora dusky. 

 Abdomen black, of normal shape; joint 1 slender but slightly broader posteriorly 

 than at base, and much narrower than 2, sides broadly bordered by a flexible, honey- 

 yellow margin ; the three basal joints sculptured, 1 and 2 densely and 3 less so ; no 

 median carina on 2; the other joints polished ; venter honey-yellow as far as joint 3. 



The cocoon is single, dense, yellowish- white, and covered with threads 

 of loose silk. 



This species closely resembles A. carduicola Pack., but differs from it 

 in several points, more particularly in the shape of the first abdominal 

 joint, which in carduicola is posteriorly almost as broad as joint 2, and 

 which has the third joint smooth, the yellow borders almost wanting and 

 the middle and posterior legs much darker. 



Described from a single specimen, bred from Junonia coenia. 



13. Apanteles carduicola Pack. 



Parasitic on Vanessa cardui. 

 Microgaster carduicola Pack., Proc. Bost. Soc. Nat. Hist., xxi, p. 27 (18S0). 



Its characters are as follows : — 



Average length, 3 mm. Head black; palpi pale testaceous. Thorax moderately 

 and uniformly punctate; the metascutum without carina; the scutellum more highly 

 polished ; fovea of postscutellum broad and with a central pit ; metascutellum with- 

 out carina. Abdomen with ovipositor just showing at tip of body ; dorsal plate of
