This very interesting grasshopper was seen for the first time, by me, 

 during the month of August last, while on a collecting trip into the 

 northwestern part of the State. Belonging, as it does, to a subfamily 

 of locusts that are particularly noted for their mimicry to certain forms 

 of vegetation, it can be readily seen how it has so long escaped the 

 eyes of collectors. This insect lives upon the stems of several species 

 of the tall grasses of that region, to which it clings so closely that it is 

 difficult to see it unless first disturbed. Even then it sometimes suc- 

 ceeds in eluding its would-be captor. Its actions are slow, as would 

 naturally be supposed from the form of its jumping legs and the small- 

 ness of its winge. It is more of a climber or walker than a jumper. 



Sub-family PYRGOMORPHINiE. 

 Dracotettix gen. nov. 



Composed of rather large and clumsy insects of dull colors, in which 

 the tegmiua and wings are somewhat shorter than the abdomen. The 

 vertex of the head, broad and projecting ; the pronotum large, cristate, 

 and quadrilobed ; the prosteruum strongly spined, and the legs as in 

 the Eremobince. Females fully twice the size of the males. 



Entire surface of body and limbs very rough, having a grauinar ap- 

 pearance. Antenna? rather short, crassate, subtriquetrous, 17-jointed, 

 the joints somewhat flattened, punctate, the apex blunt. Vertex broad 

 and projecting considerably in front of the eyes, of nearly equal width 

 throughout, almost horizontal, the lateral edges projecting, but gently 

 sulcate, furnished in the middle with a blunt, longitudinal carina; the 

 fastigium broadly rounded; lateral foveohe elongate, scarcely sulcate; 

 frontal costa narrow and very prominent above, suddenly contracting 

 to ordinary height at the ocellus, where the walls are deeply cut by a 

 profound transverse sulcus, rather deeply sulcate throughout, the walls 

 below the ocellus slightly divergent and quite heavy ; lateral facial cari- 

 na' moderately prominent and united below by a transverse carina 

 with the carina of the trontal costa, making two walled enclosures. 

 Eyes, moderately large and rather prominent, sub-globular. Pronotum 

 large and broad, with strongly marked lateral carina', which are evenly 

 divergent posteriorly, the disk nearly flat, the front and back edges un- 

 gulate, the latter greatly prolonged, as in the genus Haldemanella ; the
