AKT. 21. NEW SPECIES OF ICHNEUMON-FLIES CUSHMAN. 23 



ocell-ocular lines about equal. Thorax elongate, subcylindrical, the 

 propocleum extending nearly to middle of hind coxae, subopaque and 

 rather sparsely punctate, more densely so on mesoscutum and scutel- 

 lum ; pronotum polished in the scrobes, as is also the speculum ; pro- 

 podeum transversely rugose except basal lateral areas, which are 

 subpolished and sparsely punctate, carinae very strong, in profile 

 strongly angularly curved from base to apex, areola fully as long as 

 petiolar area ; stigma broad with radius beyond middle ; metacarpus 

 slightly longer than stigma ; basal vein nearly straight and forming 

 an acute angle with the median; second discoidal cell much longer 

 than the first brachial; upper abscissa of postnervulus little more 

 than half as long as lower; mediella obsolete basally nearly to 

 nervellus; legs rather stout, hind tarsus but slightly longer than 

 tibia, coxae opaque shagreened and sparsely punctate. Abdomen 

 rather stout; first tergite much longer than second, distinctly de- 

 curved, petiole flattened above and belov.% laterally with a deep 

 foveolate groove, merging gradually with postpetiole which is 

 flattened with a distinct impression dorsally just before spiracles; 

 postpetiole and second tergite longitudinally aciculate ; other tergites 

 opaque shagreened with very minute sparse punctures; ovipositor 

 sheath one and a half times as long as first tergite. 



Black ; orbits, narrowly interrupted on vertex and at sides of face, 

 clypeus laterally at apex, mandibles, tegulae, and wing radices 

 yellow ; legs ferruginous, hind tibia and tarsus fuscous, femur pale at 

 apex; wings hyaline, smoky at apex, veins fuscous, stigma paler; an- 

 tennae entirely black. 



Blale. — Length, 9 mm.; antennae, 7 mm. 



Except that the antennae are relatively longer, the orbits more 

 broadly yellow and uninterrupted except very narrowly on vortex, 

 the clypeus more strongly elevated and more extensively yellow, the 

 ocelli distinctly longer than the ocell-ocular line, and the abdomen 

 more slender, very like the female. 



Host — Elaphidon? in Cercis coynadensis. 



Type locality. — Rockville, Pennsylvania. 



Type.—Q2,t. No. 24625, U.S.N.M 



Described from three females and four males reared by A B. Cham- 

 plain and J. N. Knull. One paratype of each sex is returned to the 

 Pennsylvania Bureau of Plant Industry, Harrisburg. 



The size varies from 10 to 8 mm., paratype a, female, being the 

 smallest. 



Family BRACONIDAE. 



UROSIGALPHUS CRASSISCULPTUS, new species. 



Distinct from all other species having the interocellar space ele- 

 vated by its very gross sculpture, very high thornlike vertical eleva- 

 tion, and piceous legs.
