This handsome locust will be recognized by the striking 

 marbled markings of the tegmina. It has been taken in but one 

 locality in Connecticut. It occurs in numbers along the sparsely 

 clothed edges of the sand plains at North Haven. 



Psinidia Stal. 



Head rather large, with the occiput much elevated. The vertex 

 broad posteriorly, the lateral carinae high, approaching each other 

 rapidly, sloping downward, and continuous with the sides of the 

 frontal costa. The frontal costa sulcate the entire length, very 

 narrow towards the apex, gradually broadened below the ocellus. 

 Antennas long, the joints strongly flattened and three-sided 

 towards the base. Pronotum much constricted at the middle, 

 the front margin truncate, the hind margin slightly acute-angled. 

 Median carina sharp, of even height throughout, cut twice in 

 front of the middle. Lateral carina sharp and distinct on meta- 

 zona. Sides of the pronotum deeper than long. Tegmina narrow, 

 extending beyond the end of the abdomen in both sexes. Many 

 of the cells in the middle third are two to four times as long 

 as wide (Fig. 33). Towards the apex the maculations are con- 

 fined to the marginal area. Inner wings with the disk yellow to 

 orange, median band broad. Hind femora reaching nearly to 

 the tip of the abdomen in the female, surpassing it in the male.
