400 REPORT OF STATE GEOLOGIST. 



diana it is, as far as my observation goes, much less eomm.on than 

 some of the other species of the genus, having so far been taken only 

 in Crawford and Putnam counties. In the former county a number 

 of specimens were secured in June and July from beneath logs and 

 chunks in dry upland woods. In Putnam County it was found on 

 xiugust 1st beneath a log in a damp ravine. It probably occurs 

 sparingly in like situations throughout the State. 



114. Ceuthophilus latens Scudder. The Black-sided Camel Cricket. 



Ceuthophiluslatens Scndd., 14 1, YU, 1S62, 437; Id., 1 7 1 , XXX, 1894, 

 29, 64; Id., 188, 1900, 82; Bl. 7, 1893, 143. 



General color: Light reddish brown; two broad bands of dark 

 fuscous or blackish along the thorax and one or more of the basal 

 segments of abdomen, extending half way down the sides and sepa- 

 rated from one another by a median stripe of light reddish brown. 

 Below the black stripes the sides are pale yellowish brown; while the 

 greater part of the abdomen, as well as the outer face of the hind 

 femora, is dotted with brownish yellow, the dots sometimes con- 

 fluent, sometimes in apparently regular rows. The legs are light 

 brown, the tips of the hind femora infuseated. 



The fore femora a little stouter than the middle pair, nearly a 

 third longer than the pronotum in the male; but little longer in the 

 female, the inner carina with two or three spines. Middle femora 

 with two to four spines on each carina beneath. Hind femora tliick 

 and stout, the inferior sulcus of average w^idth and depth, the mar- 

 gins with several minute spines in the females; the outer carina of 

 adult males with eight or nine spines, the four or five middle ones 

 of which are quite strong and prominent, the inner carina with 11 

 to 14 small and sub-equal spines. 



Hind tibiffi straight, very little, if any, longer than the femora; 

 the inner calcaria much longer than the outer, and as long as the 

 first tarsal joint. Cerci slender, gently tapering throughout, longer 

 than the greatest width of hind femora. Ovipositor nearly twice as 

 long as fore femora, straight, the tip a little upturned and acute. 



Measurements: Length of body, male, 22 mm., female, 24 mm.; of 

 pronotum, male and female, 6.5 mm.; of front femora, male, 8.5 mm., 

 female, 7 mm.; hind femora, male and female, 19 nam.; of hind tibiae, 

 male, 21 mm., female, 20 mm; of ovipositor, 11 mm. 



Mr. Scudder has evidently described this species from immature 

 specimens of both sexes. As a consequence, his measurements are 

 much less than those given above. The spines on lower outer 

 carinas of males are more numerous and more pronrinent in the
