NO. 2349. REVISION OF NEARCTIC APANTELES—MUESEBECK. 499 



Mesoscutum and disk of scutellum distinctly punctate, the former usually 

 opaque; radius of forewing somewhat oblique to anterior margin of 

 wing, and tending outward ; usually a small knob at the point of union 

 of the radius and transverse cubitus 128. flaviconchae Riley. 



131. Inner spur of posterior tibiae longer than the outer and a little longer 



than half the metatarsus 132. 



Inner spur of posterior tibiae apparently not at all longer than the outer, 

 and not quite half as long as the metatarsus 133. 



132. Mesopleura very coarsely punctate or granular anteriorly and along the 



lower edge; abdomen in female very sharply compressed on apical 



half 129. koehelei Riley. 



Mesopleura entirely strongly shining, with only scattered punctures an- 

 teriorly ; abdomen short and broad, not compressed. 



130. anisotae, new species. 



133. Stignia narrow ; radius of forewing arising far out on stigma, so the inner 



side of the latter is alLnost twice as long as the outer side; disk of 

 scutellum very small, perfectly smooth and very highly polished. 



131. nitens, new species. 

 Stigma broader, the inner side but very slightly longer than the outer. 



132. carduicola (Packard). 



134. Sides and venter of the abdomen entirely dark testaceous, the dorsum more 



or less castaneous beyond the second tergite; radius of forewing not 



longer than the transverse cubitus 133. hesperidivorus (Viereck). 



Sides and venter of abdomen at least black on posterior half, and the 

 dorsum entirely black; radius of forewing usually longer than tran- 

 verse cubitus 13.5. 



135. First and second abdominal tergites entirely coarsely rugose, the third 



more or less roughened at base 136. 



Third abdominal tergite wholly smooth and polished 138. 



136. Abdomen very broad, almost half as broad as long; first abdominal tergite 



at least as broad at apex as long, and twice as broad at apex as second 

 abdominal tergite is long ; radius of forewing much longer than trans- 

 verse cubitus 134. cyaniridis Riley. 



Abdomen not so broad ; first tergite broadening but slightly toward apex, 



and only a little broader at apex than second tergite is long 137. 



137. Inner spur of posterior tibiae very stout and long, at least two-thirds 



as long as the metatarsus ; venter of abdomen yellow on basal half ; 

 hind coxae closely punctate on outer face below. 



135. acaudus (Provancher). 



Inner spur of posterior tibiae not so long ; venter of abdomen fuscous on 

 basal half; posterior coxae mostly smooth and shining on outer 



face 136. argynnidis Riley. 



1.38. Mesoscutum very sparsely punctate, the punctures sharp and separate, 

 confined to the anterior two-thirds of the mesoscutum, the posterior 

 third being impunctate and highly polished; disk of scutellum perfectly 

 flat, wholly impunctate and exceedingly highly polished ; first ab- 

 dominal tergite punctate, the second smooth and shining medially ; hind 

 coxae very smooth and polished ; female antennae as long as the 

 body . 137. prenidis, new species. 



Never so sti'ongly shining, nor with mesoscutum and scutellum so highly 

 poli-shed ; at least not combining all the above characters 139.
