A study of the literature on the genus Oligonyx has brought to 

 light several interesting features. In 1870, Saussure briefly de- 

 scribed Oligonyx scudderi, 9 giving North America as the locality; 

 this is explained by his remark the following year 10 under this species: 

 "Habite. Probablement l'Amerique meridionale (Etiquetee de 

 Georgie, sans doute par erreur)." Later knowledge of the species' 

 distribution shows conclusively that Saussure's type was very prob- 

 ably correctly labelled. In 1877, Stal recorded as this species speci- 

 mens from Texas, which belong to the western type discussed below, 

 and described Oligonyx uhleri from Louisiana as new, stating that 

 this species is "extremely near scudderi, something larger, tegmina 

 and wings more obscure, distinctly infuscated, limbs longer." None 

 of these characters are of sufficient importance in this insect to be con- 

 sidered of specific value, for the size and limb length are shown to be 

 variable in the series of 43 adult males before us, and the individuals 

 from the dryer western localities differ only from eastern examples 

 in having the tegmina and wings less darkened and in a few other 

 minor respects. Stal named the more eastern representative, and 

 hence his name falls as an absolute synonym of O. scudderi. Saussure 

 and Zehntner have described representatives from Dallas, Texas, 

 and Northern Mexico as Oligonyx bollianus, 11 hence the western 

 type, if sufficiently distinct to warrant racial separation, would be 

 called O. scudderi bollianus S. and Z. 



The species was found running on bare ground (Dalton, Sharp 

 Mountain), on ground in pine and oak woods (Warm Springs), 

 in oak woods (Buckhead), in swampy spot in short-leaf pine woods 

 (Yemassee) and was beaten from wire grass and undergrowth of 

 long-leaf pine woods (Albany).
