Neoconocephalus nebrascensis (Bruner) (PI. XV, figs. 2B to 2E.) 



1891. Conocephnlus nebrascensis Bruner, Can. Ent., xxiii, p. 72. [Eastern 

 Nebraska; Illinois; Iowa.] 



The present insect, though nearest N. exiliscanorus, differs 

 from that species very decidedly. In general form only, the 

 species suggests small individuals of A'', rohustus. The vertex 

 when compared with that of N. ensiger is found to be differently 

 marked and projects upward more strongly, with distal half more 

 tapering and basal tooth more prominent. The stridulating field 

 of the male tegmen is large and broad, in general form and tex- 

 ture more similar to that of rohustus than to that of exiliscanorus; 

 the stridulating vein is of moderate length and strongly swollen, 

 with accompanying veins weakly developed. 



Bruner's measurements are not exact; we give below the meas- 

 urements of the type^* and allotype: — length of vertex, lateral, 

 3.2 and 3.7; of vertex, ventral, 2.2 and 2.7; of pronotum, 8 and 

 7.5; of tegmen, 36.7 and 41.8; of caudal femur, 20.6 and 24.7; of 

 ovipositor of allotype, 32.6 mm. The length of the ovipositor 

 of the St. Louis female is 34.8 mm.
