EXPLANATION OF PLATE 26. 



Fig. 1. Ulomyia fuliginosa Meig., ^ (Europe). Wing-neuration, for reference: A, anal vein; Be, basal 

 cells, the anterior {B&) separated from the posterior {Bd^) by the median vein ; 0, costa or anterior 

 margin of wing ; Gu, cubital veins, Gu} anterior or upper branch, Gu? posterior branch ; M^ and 

 il/^ branches of the median vein enclosing the median fork ; R^, radius, and R^ to R^ its branches 

 the radial sectors, of which R^ and R^ enclose the sectorial fork ; Sc, subcosta. Cross-veins are 

 cited by quoting the lettering of the veins they link together: e.g. the cross-vein 8c to R^. Opposite 

 this cross-vein a plait or fold in the wing-membrane, shown by a dotted line, often causes difficulty 

 in ascertaining precisely the place of insertion in R* of the pedicel of the sectorial fork, without 

 first denuding the wing thereabouts : and cross-veins are sometimes hardly visible, x 38.
