610 FAMILY VII. TETTIGONIIDJE. THE CAMEL CRICKETS. 



Term. Many of these were found close to the entrances aud he 

 remarks that "This species does not vary perceptibly either in its 

 eyes or appendages, whether occurring in large or small caves or 

 living in total darkness or in partial daylight." 



Of specimens taken in White's Cave, Ivy., he (1889, 199) wrote: 

 "The 'taste cups' are highly developed in this 'cave cricket,' being 

 rounded papillae with the nucleus at the top or end. There are more than 

 100 in all where in Ceuthophilus there are only nine or ten. These gusta- 

 tory cups, being so much longer, better developed and much more numer- 

 ous in the cave Hadencecus than in Ceuthophilus, which lives under stones, 

 etc. out of doors, it would seem as if the sense of taste were much more 

 acute in the cave dweller than in the out-of-doors form, though it does 

 live for the most part in twilight." 



Garman (1891) mentions a pair of peculiar gland-like white 

 flesh} 7 appendages protruding from slits between the ninth and 

 tenth dorsal abdominal segments in the male of H. subtcrrdiicu* 

 and suggests that they may be scent glands, "the sense of smell 

 being best calculated to bring the sexes together in the darkness 

 oi' the caves." 



According to Caudell (1916, 659) the RhapMdophora carcrn- 

 arum Saussure, of which H. subtcrrcrncus was long supposed to be 

 a synonym, was not published until 1862, so that Scudder's name 

 has prioritv and 7?. carernaruin is a svnonvni.

287. HADENCECUS PUTEANUS Scudder, 1877, 37. 



"Dark fuliginous brown, slightly tinged with castaneous. Head and 

 under surface of body dull luteous; antennae luteo-fuscous, darkest on basal 

 half; palpi slightly infuscated beyond the base. Upper surface of thorax 

 and abdomen sparsely covered with excessively short hairs, giving it a 

 punctulate appearance. All the femora and tibiae brownish-fuscous, the 

 base of femora and extreme tips of tibiaa a little paler; tarsi, as well as 

 the longer tibial spines, pale luteous. Cerci brownish-luteous; ovipositor 

 testaceo-luteous, slender, not very long, in the apical half gently tapering, 

 the tip upcurved, finely pointed. Length of body, $ , 11, 9 , 17; of antennae, 

 $, 60, 9, 80; of maxillary palpi, $, 7, 9, 9.5; of hind tibia?, $ , 18, 9, 

 20.5; of cerci, $ , 4.6, $,5; of ovipositor, 7.7 mm." (Scudder.) 



The types were from North Carolina where they were found 

 under boards covering an old well. It is known also from Corn- 

 ing, Rockville and Allentown, Pa., Thompson's Mills, Billy's Is- 

 land and Rabun Co. Ga., and Monticello, Miss. The supra-anal 

 plate of male is broadly triangular, and has on each side above 

 an oblique lozenge-shaped raised disk.
