NO. 1438. WINGS OF THE TENTHREDINOIDEA—MacGILLIVRAY. 649 



gg. Front wings with the area between costa and the vein Sc^R+M 

 broad and distinct; the cell 2d R1+R2 of the front wings and cell 

 Ri+2 of the hind wings never appendiculate, never reaching the ajiex 

 of the wing, and bluntly rounded at apex; the free part of the vein 

 M4+CU1 joined to the cell 1st A near its apex, over three times the 

 length of the free part of the vein 2d A from its base. 



MEGALODONTID^ 

 ee. Front wings with the medio-cubital cross-vein joined to media at or near 

 its point of separation from radius, never less than three and usually 

 four or five times the length of the transverse part of media; the portion 

 of the radial sector between the stigma and the anterior end of the 

 radio-medial cross-vein subequal to or greater, usually greater, than the 

 portion between this cross-vein and the posterior end of the radial cross- 

 vein, resulting in the apex of the cell R extending to near the apex of 



cell 1st Ri CEPHID^ 



dd. Front wings w ith the transverse part of the vein ^\.^ wanting. .ORYSSID^E

 bh. Front wings with the second anal cell not contracted at middle, 

 c. Radial cross-vein present. 

 (/. Front wings with the medio-cubital cross-vein joined to the vein Sc+R+M 

 at or near the oi'igin of media, its distance from media always less than 

 one-half the length of the cross-vein. 

 e. Front wings with the medio-cubital cross-vein and the vein JVI3+4 parallel. 

 /. Front wings with the base of the third anal vein present and the 

 second anal cell therefore not combined with the third . . .Lycaotin.e 

 ff. Front wings with the base of the third anal vein atrophied or at least 

 in part so that the second and third anal cells are combined. 



Blenxocampin.e 

 e. Front wings with the medio-cubital cross-vein and the vein M3+4 strongly 

 divergent 1)ehind. 

 /. Hind wings witli the vein Rg reaching the margin distinctly l)efore the 

 apex of the wing; the cell Ri+2 pointed at apex and closed. 



SCOLIONEURIN^E 



ff. Hind wings with the vein R3 reaching the margin at or beyond the 



apex of the wing; the cell R1+2 round at apex and open Fenusin^ 



dd. Front wings with the medio-cubital cross-vein joined to the veinSc+R+M 

 distant from the origin of media; its distance from media always one-half 

 or more of the length of the cross-vein.
