1908 THE BUTTERFLIES OF NEW ENGLAND. 



joint 1 narrowest at base, its length exceeding its width at hind border, its lateral 

 edges slightly arcuate and rounded behind; joints 1 and 2 rugose; rest of abdomen 

 perfectly smooth, polished and with little trace of hairs; the radius of wings normal; 

 stigma rather inroad ; radial vein strongly angled ; coxae and trochanters Ijlacli ; basal 

 one-third to one-half of front femora blackish, rest ferruginous and concolorouswith 

 tibiae; tarsi brownish, base of first tarsal joint paler; middle and hind femora black- 

 ish; tibiae ferruginous, with a slight dusky tinge; tarsi pale at base, becoming Ijlack 

 towards claws. 



11 specimens, all 9 , are before me Ijred by Mr. Scudder from Vanessa 

 cardui, but no cocoons accompany them. 



The species closely resembles Apanteles theclae Riley, but may be dis- 

 tinguished by having no median ridge on metascutellum, by the more 

 closely punctate basal joints of abdomen, by the slightlj^ larger size, by 

 the more intense angulation of the radial vein, the lack of punctation 

 beyond the second abdominal joint, and in the almost complete absence of 

 hairs from the abdomen. 



14. Apanteles atalantae Packard. PI. 88, fig. 13. 



Parasitic on Vanessa atalanta and Aglais milberti. 



Dr. Packard's colorational description (Proc. Bost. Soc. Nat. Hist.j 

 xxi, p. 27) which would apply to many different forms is as follows : 



"Body jet Ijlack, polished; antennae blackish brown; palpi whitish; mandibles palb 

 reddish, blackish at base. Legs with the coxae black ; trochanters blackish at base, 

 all beyond dark honey-yellow; terminal joint of tarsi a little dusky." 



From limited material and the description I formerly considered this 

 a variety of congregatus (Am. Nat., 1882, p. 070) ; but from a larger 

 number of specimens since examined it may Aery well remain as a good 

 species, intermediate in some respects between glomeratus and congregatus 

 by comparison w ith which it may best be characterized. 



From glomeratus it differs in the more convex, more densely punctate face without 

 diverging carinae ; in the lateral ridges of metathorax being more distinct. From con- 

 gregatus it ditt'ers in being less hairy, in the less densely punctate face without distinct 

 tubercle, and in its concolorous coxae. From both .species it is distinguished by the 

 smoother second joint of abdomen, the sculpture being confined to the lateral borders; 

 by the stigma l)eing shorter and darker, the angle of the radial vein more pronounced 

 and above the middle of the vein, i. e., nearer to the stigma; and finally by the sheath 

 of the ovipositor being broader, more strongly developed and projecting somewhat 

 more beyond the tip of abdomen. 



In some specimens, the middle portion of the first abdominal joint is also smooth 

 and impunctate. 



I have examined some 50 specimens fi'om atalanta and 1.5 from milberti 

 reared by Packard, and 2 specimens from milberti reared by William H. 

 Edwards. There arc no entomophagic differences whate\er in the spec- 

 imens.
