Neoconocephalus caudellianus (Davis) (PI. XVI, figs. 9B and 9C.) 



1905. Conocephalus caudellianus Davis, Can. Ent., xxxvii, p. 289. [Lake- 

 hurst, New Jersey.] 



The present insect closely resembles N. robustus 7'obustus, l^ut 

 the vertex is very decidedly shorter with sides usually very weakl}^ 

 convergent distad and apex rotundato-truncate, more so than in 

 typical robustus crepitans, and with ventral surface 

 rather heavily outlined in black, this marking 

 showing but little variation in the series before 

 us. The stridulating field of the male tegmen is 

 very similar to that of robustus robustus but very 

 slightly more elongate; the stridulating vein is 

 somewhat more decidedly swollen in proximal two- 

 thirds with accompanying veins distinctly heavier 

 where they join this vein. 



The green color phase appears to greatly out- 

 number the brown, and in such individuals the 

 green is distinctly richer than in robustus. With 

 species showing such close relationship, it is sur-
