 RTLOTOMINA, LOPHYRINA, AND LYDINA. 



BY P. CAMERON. 



{Continued from p. 51). 



HTLOTOMINA (i, p. 65). 



Thomson divides the Hylotomina into two sub-tribes : the Hylo- 

 tomides with the hind tibiae spinedand the radial cellule appendiculate ; 

 and the Schizocerides with no spines on tibiae, and the radial cellule 

 not appendiculate ; the latter, having the antennae furcate in the 

 males. Of the first group we have only one genus, the well-known 



HYLOTOMA, Latr.
