This is the typical section of Graphiphora and besides the genotype, 
c-nigrum Linn., the writer includes smithi Snell, (which is distinct genitalic- 
ally from baja Scbiff. and in which the fore tibial spining is present but hard 
to see beneath the vestiture), normaniana Grt., ditrapezium SchifL, conchis 
Grt., trumani Sm. (probably same as the European xanthographa Schiff. 
and atypical as regards thoracic vestiture, which is hairier and untufted), 
and oblata Morr., which has a double pollex and spiculate bands at apex of 
aedoeagus, also smaller eyes as in Pachnobia. 
Group II 
Male Genitalia. Differs from those of Group I in having a stronger 
harpe, projecting considerably over costa; the base is also strong, with a 
tendency for the distal end to be raised free from the clasper. 
Figure 34. Male genitalia of Graphiphora substrigata Sm. 
The writer includes the two rather dissimilar species substrigata Sm. 
and cineraseens Sm. in this group; in both the third palpal joint is tufted 
with hair apically, but in the former the spining of the fore tibia is stronger 
than usual, especially the outer row. As far as can be judged from the 
limited material of cineraseens before the writer, the thoracic tufting is less 
developed in this species than in substrigata, which in this respect resembles 
the typical section. 
The following groups agree among themselves and show a distinct 
divergence from the two preceding ones in that the foot-like attachment 
of the harpe is no longer evident; the distal portion has become obsolete, 
and the proximal section forms a curved chitinous rod more or less attached 
to the apex of sacculus. The shape of the clasper is variable. 
Group III 
Third palpal joint with pointed tuft of hair below. Vestiture rather 
hairy with no prominent tufting on thorax.
