48 ' ORTHOPTEROUS GROUP INSARAE 



pale green and a brown color phase. The remaining forms, I. 

 elegans, elegans consuetipes, covilleae and gemmicula, known almost 

 wholly from north of the Mexican boundary, all (excepting elegans 

 consuetipes) invariably have a dark brown maculation present on 

 each side of the fourth abdominal segment near its caudal margin, 

 which margin caudad of this maculation is paler than the general 

 coloration of the abdomen. This marking is greatly intensified 

 and specialized in gemmicula; much intensified, with the pale caudal 

 margin very pronounced, in covilleae; not strikingly prominent in 

 elegans, and very much reduced, often absent in elegans consue- 

 tipes. The general color pattern is distinctive in each of these 

 species. 



History. — In 1869, Walker erected the monotypic genus Insara^ 

 and described the species strigulata; Kirby, in 1906,^0 recognizing 

 this species to be a synonym of Saussure's Phaneroptera tolteca,^^ 

 described in 1859, correctly associated these names. 



Unfortunately Walker's genus Insara was unrecognized by Stal 

 in 1873, which resulted in his erecting the synonymic genus Hor- 

 milia^" which latter name has been used throughout the literature 

 to the present date excepting in Kirby's Catalogue. 



In 1878, Brunner^^ described four species as H. gracillima, inter- 

 7nedia, ahbreviata and fasciata. The first three species belong to 

 the present genus, but the South American species, fasciata, which 

 the author suggested might be considered a member of a different 

 genus, does not belong to Insara as the characters given for that 

 species unquestionably show. 



The same author also described two species in 189P^ H. peruvi- 

 ana and latipennis. The original descriptions prove that these 

 species are not members of the genus Insara and we have been 

 enabled through the examination of a male of latipennis to erect 

 for it a new genus, Dolichocercus, in the present paper. 



Griffini, in 1896, described a single species, H. bolivari^'^ and the
