HYMENOPTEROUS PARASITES. 1883 



and basal half, or tTvo-tliirds of third segments ; venter pale luteous ; ovipositor of ? 

 longer than basal segment. Length, 1.5 mm. (After Cresson.) 



This species was bred by Mr. Cresson (twenty-four specimens, together 

 with four specimens of a Pezomachus) from a bunch of bright yellow co- 

 coons (probably those of a Microgaster) found attached to a blade of 

 grass in Pennsylvania. 



I have seen three specimens of what seems to me to be this species in 

 the National Museum collection at Washington which were received from 

 Miss M. E. Murtfeldt of Kirkwood, Mo., Oct. 18, 1881 and by her said 

 to be parasitic on some "large parasite" of Eurymus philodice. 



Genus LIMNERIA Holmgren. 



Head moderately large, transverse, not inflated; eyes naked, not emarginate ; clypeus 

 normal, not carinate or denticulate. Thorax longer than high; metathorax distinctly 

 areolated, not produced at apex. Stigma of forewingsof moderatesize; areoletsmall, 

 usually trianguliir, often petiolate, sometimes absent. Abdomen moderately broad 

 and moderately or slightly compressed towards apex, the incisures between segments 

 very distinct ; petiole slender, longer than the transverse post-petiole.

Abdomen black f ugitiva. 



Abdomen almost entirely rufous llmenitklls. 



Limneria fugitiva Say. 



Body black ; antennae in both sexes black ; mandibles and palpi white ; tegulae white ; 

 wings hyaline, nervures black, whitish at base, areolet very small, petiolated from the 

 radial cellule ; met.anotum not excavated behind, but with "somewhat raised lines"; 

 abdomen arcuated, towards tip rather abruptly clavate ; punctures very small; oviposi- 

 tor as long as tip of abdomen ; feet honey-yellow with a white reflection ; posterior 

 tibiae white with a black tip and base; posterior tarsi black, base of flrst joint white; 

 in the male the white of the posterior tibiae is less obvious. Length, from 6 to 7.5 mm. 

 (After Say.) 



Say reared this species in Indiana from a "pretty white cylindric cocoon 

 with maculated black bands." 



As a butterfly parasite this species has been reared from Pholisora Catul- 

 lus by Professor Riley in Missouri, from Chlorippe celtis by Mr. W. H. 

 Edwards in West Virginia, and from Chlorippe clyton by Mr. A. H. Mundt 

 in Illinois.
