the pronotum. The antennae yellowish brown at base, dark 

 brown or black towards the tips. The sides of the abdomen 

 marked with black and the knees of the hind legs also black. 

 The tegmina are extremely variable, and, while most of the in- 

 dividuals belong either to the short-winged or to the long-winged 

 forms, no line can be drawn between them, as many examples are 

 found varying from one form to the other. In the short-winged 

 specimens the tegmina usually lack 3-5 mm. (females) or 2-3 mm. 

 (males) of reaching the end of the hind femora. In the long- 

 winged form they reach the end of the hind femora or pass 

 it by 1-2 mm. The hind wings are always present, somewhat 

 shorter than the tegmina, their usefulness depending upon their 

 size. The males resemble those of Chloealtis conspersa, but are 

 readily distinguished by the presence of the foveolae (Fig. 24).

This species is often abundant in the tall grass of moist 

 meadows, along ditches, or wherever the vegetation is thick and 

 succulent. Morse states, " The season during which it may be 

 procured in the adult state is the longest of all our locusts. I 

 have captured specimens from June 24th to November i/th." 

 We have taken it in various parts of the <tate from 1 1 July to 

 4 October. 



Mecostethus Fieber. 



Head with the vertex horizontal, the median and lateral 

 carinae distinct, the latter straight. Apex truncate or broadly 

 rounded. Lateral foveolae small, triangular. Antennae of male 

 slightly exceeding the head plus the pronotum. Pronotum with 

 the three carinae distinct, the median carina prominent, cut some- 

 what in front of the middle. The disk rugose, with the posterior 

 margin obtuse or rounded. The lateral lobes about as deep as 

 long. Tegmina and wings well developed, usually surpassing 

 the tip of the abdomen in both sexes. The intercalary vein 

 elevated, and in the male furnished with a stridulating rasp. 

 Hind femora rather slender, exceeding the tip of the abdomen in 

 the male. Sub-anal plate of the male long, at least twice the
