Table (if the N. E. Species of' Mcla>iopl!is : Females. 



a'. Teginina no longer or scarcely longer than the pronotum. 



b'. Interspace between mesosternal lobes quadrate or slightly longer than broad ; 

 median carina as distinct on the prozona as on the metazona ; basal tooth of 

 lower valves of o\ipositor blunt and rounded .... scudderi. 



b". Interspace between mesosternal lobes distinctly transverse ; median carina 

 less distinct on the prozona than on the metazona ; basal tooth of lower valves 

 of ovipositor sharp, rectangular ....... mancus. 



a-. Tegmina much longer than the pronotum, often surpassing the abdomen, 

 b'. Lower valves of ovipositor apically more or less distinctly decurved, with a 

 distinct median tooth on the lower outer margin ; prosternal spine moderate or 

 long, generallv about as high as the jnesosternum. 



c'. Interspace between mesosternal lobes longitudinal or quadrate. 



(1^. Rather large ; prozona distinctly longitudinal ; line of division between 

 the dorsal and lateral areas of the closed tegmina marketl by a yellow stripe 

 generallv extending forward to niark the lateral carinae of the pronotum. 



fcmorahis. 

 d'-. Medium sized ; prozona quadrate oi- transverse ; no \ellow stripe on 

 tegmina or lateral carinae. 



e'. Median carina of pronotum generally indistinct or wholly wanting 

 on the prozona ; prosternal spine as seen from in fiont tapering, gener- 

 ally bluntly pointed at tip . . . . . . atlanis. 



e'". Median carina of pronotum generallv distinct on the prozona; pro- 

 sternal spine nearly cylindrical, as seen from the front scarcely tapering 

 except at extreme tip, which is generally lilimth' rounded, sometimes a 

 little enlarged ....... femur-nibrum. 



c*. Interspace between mesosternal lobes distinctly, sometimes strongly 

 transverse. 



d'. Interspace between mesosternal lobes strongly transverse ; tegmina 

 generally shorter than the abdomen ; median carina almost as distinct on 

 the prozona as on the metazona ; interval between eyes above narrower 

 than in the alternate category. 



e'. Hind femora with no transverse bands ; metazona obscurely and 

 bluntly ruguloso-punctate ...... extrcvtus. 



e-'. Hind femora vfcfith dark oblique fasciation ; metazona distinctly and 

 sharply ruguloso-punctate ...... fasciatus. 



d-. Interspace between mesosternal lobes but little transverse ; tegmina 

 always as long as the abdomen; median carina distinctly dulled on the pro- 

 zona ; interval between eyes above broader than in the alternate category.
