1909] American species of Scolionevirinae 269 



ly convex; antennae long and slender, the first and second segments 

 together one-half the length of the third, the third longer than the 

 fourth and shorter than the fourth and fifth together, the fifth and fol- 

 lowing segments subequal in length, the ninth segment strongly con- 

 vex on the basal third and gradually, convexly, tapering to a point, 

 the third and following segments more or less serrate on one side ; tlie 

 front wings with the radio-medial cross-vein present, hyaline, or want- 

 ing; the free part of M4 + CU1 received near the middle of the cell M^; 

 the stigma twice as long as wide, broadly convex on the lower margin 

 and at apex; the free part of R^ twice the length of the free part of R5; 

 the hind wings with the cell R1+2 closed and appendiculate at apex; 

 the wings varying from brownish to hyaline, the veins, stigma, and 

 costa black or brown ; the posterior metatarsus distinctly shorter than 

 all the following segments together, the second segment longer than 

 the third and almost half the length of the metatarsus ; the saw-guides 

 broad, straight above, convex below, obliquely truncate at apex, 

 broadly rounded at lower angle, and rather sharply pointed at upper 

 apical angle. Length 3-4 mm. 



Habitat. — Illinois (Forbes) ; Dover, Delaware (Houghton) ; 

 New York (Cornell Agricultural Experiment Station) ; River 

 de Pere and Central Missouri, Riley Collection. Bred from 

 larvae found on cultivated blackberry and on dewberry. 



An extremely variable species in coloration and head structure. 

 This may represent more than one species but the material at 

 hand does not warrant its subdivision at the present time. The 

 male differs only in its smaller size and in having the antennae 

 more decidedlv flattened and saw-toothed than in the female. 



Entodecta Kmv. 



Head transverse, the front not as broad as high; the inner 

 margin of the eyes uniformly convex, the eyes distinctly con- 

 verging below; the antennal furrows obsolete except adjacent to 

 the antennal foveae and behind the lateral ocelli; the clypeus 

 slightly emarginate, not more than half as wide at apex as at 

 base; the antennae long and slender, filiform, the second seg- 

 ment distinctly shorter than the first, wilder than long, annular, 

 not so wdde as the first, the first and second together distinctly 

 shorter than the third; the front wings with the free part of R4 

 and the radial cross-vein not interstitial and inclined at the same 

 angle; the free part of M4-fCui received distincth- before the 

 middle of the cell ist A-l-2nd 2nd A; media gently curved at 

 the point of separation of M1+2 and M3+4; the radial sector almost 

 straight, oblique at base. Type Tenthredo pumila Klg.
