NoTic 111. Description of Parasite of Canc-Lcaf ffoppcr. 



I here give the characters of a highly interesting and import- 

 ant Hymenopterous parasite of the leaf-hopper, for which it is 

 necessary to make a new generic name. Its life history has l)e:n 

 partiall)- written in the earlier part of this report. 



Ecthrodelphax — New genus : 



Generally similar in structure to GoiiatoMis Pcrkinsi Ash in., 

 but winged, anrl the thorax consequently much modified. 



Anttnnae evidently thickening towards the apex, second joint 

 of the flagellum very elongate and slender, first much shorter and 

 thicker, about equal to third in length. Head about twice as wide 

 as the prothorax, above distinctly concave between the eves, pos- 

 teriorly emarginate. Prothorax twice as long as its width at 

 ])ase, wider on its anterior than on the posterior half. Mes- 

 othorax greatly narrowed in front, its sides being strong- 

 ly convergent, the furrows crenate, contiguous at the scutellum 

 and thence divergent anteriorly, so as to enclose a narrow tri- 

 angular area. Tegulae placed far back on the mesothorax. and 

 very remote from the prothorax. Legs as in the Goiiafopns al>ove 

 mentioned, the front trochanters very long and clavate, the apical 

 part being thickened, all the femora clavate, the basal part thick- 

 ened ; claws of the front tarsi verv long, asvmmetrical, but of
