250 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



fasciatus the abdomen, particularly in males, is distinctly tris- 

 triate, which contrasts strongly in that sex with the green cerci/^ 

 In addition to nearly one thousand recorded specimens which 

 have been recently examined by us, we here record a single 

 female.

Saussure's name, Xiphidium mexicanum, based uponniacrop- 

 terous examples of this species,'*^ is unfortunately not available 

 at the present day; the present use of the name Conocephalus 

 for the genus then called Xiphidium prevents the use of his 

 ■specific name, as on the same page of the work in which the 

 present species is described, and having line priority, we find 

 Conocephalus mexicanus described, which species is now placed 

 in the genus Neoconocephalus. Scudder described brachypterous 

 examples of the same species as Xiphidium ictum, which specific 

 name must be used as the first available for the species. 



The position of the present insect is between C. cinereus and 

 C. spinosus, from both of which species it differs decidedly in 

 general appearance; the males suggesting very heavy and deeply 

 colored males of C. stricius, while the females suggest, to some 

 degree, large and very heavy examples of that sex of C. brevi- 

 pennis. From cinereus this species differs in the much more 

 robust structure, more truncate form, normally broader vertex, 

 decidedly more quadrate lateral lobes of the pronotum and 

 decidedly larger tympanum of the male tegmina with much 

 longer stridulating vein. The male cerci of the two species are 



^8 In life, certain species of the genus have the cerci green; this excellent 

 character can not be used for dried material as the green coloration often fades 

 or even completely disappears in drying. 



^9 We have before us a brachypterous male specimen taken by Sumi(?hrast 

 in Mexico, received from Saussure and identified by him as his A', mexicanum, 

 probably originally from the same series on which Scudder's name is in part 

 based.
