406- STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



synonym for triops, for at that time the descriptions then extant 

 of the species were all very inadequate; but the inclusion of ma- 

 terial of the present species in the series of hebes described by 

 Scudder, in 1878, can only be attributed to carelessness, and 

 Redtenbacher's evident naming of the brown color phase, in 1891, 

 as fusco-striatus should have been avoidable to one whose knowl- 

 edge of the genus was so extensive. Karny's variety tibialis is 

 even less deserving of name recognition, based soleh^ on dark ex- 

 amples of the brown color phase. 



In recording material from the United States, the names tiietoi 

 and obscurellus have been used, the former a number of times and 

 the latter once;^" the majority of these records we know apply 

 to the present insect and we feel certain that the others do like- 

 wise, these species (of which Saussure's type of Conocephahis 

 nieti is apparently a member of the genus Homoroconj-phus) being 

 found south of the region at present under consideration. 



The present insect is easily recognized, and as it is the only large 

 and robust species of the genus having a very short broad vertex 

 which is found in the region under consideration. 



The stridulating field of the male tegmen is of medium size and 

 rather broad; the stridulating vein is heavy and rather long, with 

 accompanying veins heavy where they join this vein, which, at 

 its distal extremity, has two very small but conspicuous pits, 

 one on each side; the veinlets of this area are exceedingly numerous 

 and extremely weakly defined. 



The male cerci of the present species are slightly different from 

 those of the other forms here considered, having a more or less 

 decided knoblike production at the base of the distal arms. 



The ovipositor is distinctly compressed beyond the enlarged 

 basal portion ; distad the shaft has a distinct but very weak down- 

 ward curvature. 



The moderate amount of size variation which occurs in this 

 species has no geographic significance, as is shown by the large 

 series before us. 



30 It is this record of Saussure and Pictet, Biol. Cent. Amer., Orth., I, 

 p. 392 (1898), which unfortunately causes the name obscurellus to appear 

 in Scudder's Catalogue of the Described Orthoptera of the United States 

 and Canada. See foot note No. 35.
