HYMENOPTEROUS PARASITES. 1903 



The male differs but slightly, the front and middle femora being usually 

 darker. One female has all legs yellow except extreme tip of hind 

 femora. 



Described from numerous specimens reared from B. archippus and others 

 (var. flaviconchae) from cocoons found in fields infested with Leucania 

 unipuncta. 



The cocoons from archippus are from young larvae of autumn brood and 

 are dull whitish, single and with little loose silk. Those of form flavicon- 

 chae are pale yellow and in masses with a small amount of loose silk. 



5. Apanteles lunatus (Pack.). 



Microgaster lunatus Pack., Proe. Bost. .Soc. Xat. Hist., xxi, p. 28 (1880). 

 Parasitic on Papilio poly.xenes. 



This species was described by Dr. Packard from a single female bred by 

 me from Papilio polyxenes. Mr. Scudder is not able to find the specimen, 

 and hence I can only adopt Dr. Packard's description : 



Body dull black, not shluing, stout and thick. Head and autenuae covered with an 

 unusually dense silvery pile, the autenuae rather thicker than in M. pierklis ; palpi pale 

 testaceous; front rather broad Ijetween the eyes ; thorax dull black; metauotum with 

 no median ridge. First subcostal cell instead of being irregularly oblong, is much 

 broader and irregularly pentagonal. Fore and middle trochanters black, legs deep 

 honey-yellow with a slight reddish tinge, outer third of tarsi pale brownish; hind 

 femora reddish honey -yellow tipped with black, tarsi wholly black. Abdomen entirely 

 black, granulated as usual on two basal segments, polished beyond, a faint dull testa- 

 ceous spot on under side of tirst segment, not appearing above. Length, .13 inch. 



I have one female in poor condition reared from polyxenes received from 

 W. B. Thomas, of Athens, Ga. in 1885, which is apparently this species, 

 and which is characterized by a minute tubercle on the face, by the scutel- 

 lum being densely punctate and not polished and by the basal joint of palpi 

 being black. The metascutellum has no carina but is heavily pilose. Ab- 

 dominal joint 1 narrow, the hind border almost as wide as the joint is long, 

 without carina, but with a strongly marked median tubercle, extending to 

 anterior border of joint 2, with both joints and basal part of 3 strongly 

 rugose. Ovipositor but slightly exserted, the sheath extending but a short 

 distance beyond the tip of abdomen. 



The cocoons are single, dense, dull yellow and with but little loose silk, 



6. Apanteles cyaniridis n. sp. 



Parasitic on Cyaniris pseudargiolus. 



Length, 2.8 ram. ?: Pilosity sparse. Head: face without carina ; palpL pale yellow. 

 Thorax : mesoscutum with barely a trace of a carina ; scutellum hardly more polished
