Genus HADENOECUS Scudder. 



Hadennecus Scudder, Bost. Journ. Nat. Hist., vol. 7, 1862, p. 439. 



This genus of long-legged insects, of which Rhaphidophora sub- 

 terranea Scudder is the type, comprises two species which may be 

 separated by the following key: 



KEY TO THE SPECIES OF HADENOECUS. 



Ovipositor nearly or quite as long aa the body; general color pale testaceous; living 

 mostly in caves subterraneus Scudder. 



Ovipositor considerably shorter than the body; general color dark brown; living 

 mostly in and under the covers of wells puteaniis Scudder. 



HADENOECUS SUBTERRANEUS Scudder. 



The EhapTiidophora cavemarum of Saussure was estabhshed in a 

 paper presented in 1860 but not pubHshed until January 22, 1862.* 

 Scudder's subterraneus was pubhshed in 1861 and, as the two names 

 have been found to apply to the same species, Scuader's name must 

 be used as it is the earher. This fact was not understood by Scudder, 

 who sank his own name in favor of that of Saussure, which he dated 

 from 1860 instead of 1862, as is actually the case. 



This species has been reported only from caves in the southeastern 

 United States. 



HADENOECUS PUTEANUS Scudder. 



This species is closely allied to the preceding, but the ovipositor 

 is noticeably shorter and the general color is darker. It seems to 

 occur in and under the coverings of wells and has been recorded from 

 Georgia, Mississippi, and North Carolina. In the Hebard collection 

 in Philadelphia there is a male from Corning, Pennsylvania, taken 

 by Helen Cleland. 



Genus DIESTRAMMENA Brunner. 

 Diestrammena Brunner, Verhandl. k. k. zool. bot. Ges., vol. 38, 1888, p. 298. 



This genus is represented in our fauna by two species, both intro- 

 duced. These long-legged, short-bodied insects are not well known 

 in the New World and a somewhat comprehensive description of the 

 genus is therefore here presented. 



Head as broad as the anterior portion of the pronotum; vertex 

 between the antennae forming a pair of elongate conical tubercles, 

 about twice as long as the basal width; antennae nearly or quite 

 three times as long as the body and very slender beyond the enlarged 

 first and second segments, the second segment about one-half the 

 length and thickness of the first; palpi long and slender, the apical 

 segment very gently enlarged distaUy, cleft beneath only apicaUy and 



' Ann. Soc. Ent. France, ser. 4, vol. 1, 1862, p. Ivi, gives the dates of publication of the vaiious parts of 

 this volume.
