Males are more numerous, or at least 

 more are captured, than females, prob- 

 ably being readier to take wing and in 

 consequence felling into the net in 

 sweeping. The species prefers sedgy 

 meadow-lands and swales on sandy 

 soil occasionally flooded bv rains or 

 freshets and perpetually moist. The 

 bulk of my specimens were taken on a 

 boggy swamp which had been filled in 

 with sand, and on which water stood 

 more or less of the time.

This species was unknown to Bolivar 

 who left it in Tettix, being misled 

 perhaps by Scudder's statement that it 

 most resembles T'. granulatns and 

 failing to appreciate properly the charac- 

 ters given in Scudder's description, 

 which he quotes. It belongs, without 

 doul)t, as shown by the structure of the 

 veitex and spiculate character of pulvilli 

 of proximal joint of hind tarsi, in 

 Bolivar's genus Paratettix and seems 

 to be fairlv well described under the 

 name of P. niexicanns Sauss. 



Description-, etc. — It is easily recognized \ty 

 the form of the vertex [Figs. 4, 43]. From 

 above this appears about equal in width to 

 one of the large and prominent eyes, and 

 does not project in advance of them; its 

 front margin is slightly hollowed, the con- 

 cavity being divided by the mid-carina which 

 projects a little. In profile the frontal costa 

 is slightly sinuate opposite the eyes and 

 strongly protuberant opposite the antennae. 

 The croAvn of the head is channeled long- 

 itudinally on either side of the mid-carina, 

 the sulci being stopped abruptly opposite the 

 liinder portion of the eyes by a pair of 

 transverse, sometimes slightly oblique, 

 ridges. This character is found in several 

 species of this genus and in this species 

 appears at a very early stage, showing dis- 

 tinctly in specimens 3 mm. in length. The 

 body is less compressed tiian in the preceding 

 species, being, in truth, depressed rather than 

 compressed. The pronotum is advanced 

 upon the head to the eyes, and the median 

 carina is obsolete on the anterior portion ; 

 the posterior process extends 2-3 mm. beyond 

 the hind femora, exceeded by the w^ngs, and 

 is very constant in proportions.

In color and ornamentation it is one 

 of the least variable of our species, 

 resembling closely its smroimdings in 

 tint and textiu'e, varying from mottled 

 vellowish-grav almost to dull black. 



Habits, etc. — In distribution it 

 appears to Ije somewhat southern, and 

 ver\' local. It piefers the immediate 

 margin of lakes and streams, often 

 alighting on the water when disturbed, 

 and swimming well. I have taken it in
