Grasshoppers of Kansas. 91 



The flatter disk of the pronotum with its slight but abrupt median 

 carina and almost equjally distinct lateral carina? distinguish this at once 

 from Tragocephala, with which Doctor Stal unites it. As he has pointed 

 out, the intercalary vein of the tegmina approaches the ulnar vein, 

 instead of lying midway between it and the radial vein, as in Trago- 

 cepli a la . 



Encoptolophns sordidus Burm. 



Size large for the genus; face blunt; frontal costa scarcely sulcate, 

 lateral carinas of same parallel below the antenna?, convergent above; 

 lateral foveolae trigonal, shallow; fastigium of vertex large, heart-shaped, 

 with a median carina from the center caudad; antenna? slender, of 

 medium length; pronotum not much wider caudad than cephalad; carina 

 sharp, higher and wider on the prozona than on the metazona, cut by one 

 sulcus; tegmina a little longer than the body; fasciate with fuscous, 

 scarcely hyaline apically; wings with disk whitish hyaline, no arcuate 

 black band, apical half more or less infuscated, the anal and axillary 

 veins black; inside of hind femora black with two light bands and a 

 basal light spot; tibia? blackish blue with an apical light band. 



General color very dark, quite strongly maculate. This species is 

 quite common in Douglas county late in the fall. Just why it should 

 not occur or have been taken in more localities in the state is rather 

 difficult to answer. Possibly it is because the collecting parties return 

 before this species reaches the adult form. A female of this species was 

 taken mating with Dissosteira Carolina.

Encoptolophus texensis Brunei'. 



In size a little larger than costalis. Color brownish fuscous with 

 maculations, but more indistinct than in costalis Sc. Head slightly 

 elevated above the level of the pronotum. Antenna? filiform, of medium 

 length. Frontal costa sulcate in region of the ocellus and below, sides 

 parallel below antenna?, convergent above. Lateral foveola? trigonal, not 

 very distinct. Fastiguim of the vertex of medium size, slightly sulcate ; 

 longer than broad in the male, about equal in the female. Pronotum 

 very little constricted cephalad ; median carina well marked and sharp 

 but not high, cut by one sulcus. Tegmina long and narrow, maculate, 

 apical fourth semihyaline; ulnar and median veins of moderate separa- 

 tion, intercalary vein slightly nearer the ulnar than the median vein, 

 usually almost straight, the space between them filled either with one 

 row of cells or a reticulate mass, usually with more than one row of 

 cells. Wings with basal disk hyaline with a yellowish brownish tinge, 

 no arcuate band, apically infuscated, less so than in sordidus, axillary 

 vein shining black, the anal lighter. Posterior femora robust, stout, 

 black on the inside with two apical light bands and a small light blotch 

 basally at the upper side, tibia? bluish with a lighter annulus basally.
