A New Species of Ceuthophilus (Orthoptera) 

 from Kansas. 

 By James A. G. Rehn. 

 Ceuthophilus tuckeri n. sp. 



Type : <? ; Lawrence, Douglas County, Kansas. October, at 

 night. (E. S. Tucker.) [Coll. Univ. of Kansas.] 



Allied to C. secretus and varicator Scudder, but differing from 

 the former in the cephalic femora being less than half again 

 as long as the pronotum, in the caudal femora being but 

 slightly more than three times as long as broad, in the broader 

 ventral sulcus of the same and in the longer median internal 

 calcaria. From varicator it differs in the slightly broader cau- 

 dal femora, in the spined latero-ventral margin of the caudal 

 femora and in the much smaller size. 



General size medium ; form moderately compressed, dorsal outline 

 distinctly arcuate ; surface smooth. Head with the fastigium sharply 

 descending, almost vertical, not sulcate, apex rounded ; eyes subpyri- 

 form, the greatest width dorsad ; antennae about three times as long as 

 the body, proximal joint broad. Pronotum, with the cephalic margin 

 slightly emarginate mesad, caudal margin truncate. Mesonotum slightly 

 produced, arcuate ; metanotum subtruncate. Terminal dorsal abdominal 

 segment with a slightly elevated and thickened margin mesad ; cerci 

 slightly shorter than the pronotum, tapering, curved. Cephalic femora 

 about a third again as long as the pronotum, ventro-cephalic margin with 

 one to two spines on the distal portion, ventro-caudal margin unarmed ; 

 cephalic tibiae with the dorsal face unarmed, ventral margins with four 

 spines ; cephalic metatarsi slightly shorter than the remaining cephalic 

 tarsal joints. Median femora about equal to the cephalic femora in 

 length, ventro-cephalic margins with two distal spines, ventro-caudal 

 margins with a single distal spine ; median tibiae with two pairs of spines 

 dorsad and five pairs ventrad including a terminal pair ; median meta- 

 tarsi about equal in length to the remaining median tarsal joints. Caudal 

 femora very slightly longer than the normal length of the body, the great- 

 est width contained slightly more than three times in the length and also 

 placed at about a third the distance from the proximal extremity, ventral 

 sulcus rather broad and comparatively shallow, the lateral carina with 

 two large spines and a number of smaller ones placed distad and proxi- 

 mad of the larger ones, internal carina with a number of irregular small 

 serrato- dentate spines ; caudal tibia about a fifth again as long as the cau- 

 dal femora, dorsal carinae with four pair of strongly divergent spurs, 

 margins serrato-dentate, terminal calcaria three-paired, the median one 

 on the lateral aspect three-fourths the length of the metatarsus, the me-
