266 ORTHOPTERA OF XOVA SCOTIA.— PIERS. 



This species is verj^ abundant throughout New England, 

 where it reaches maturity early in July, and is found nearly 

 everywhere on dry, sandy or loamy soils of pastures and 

 cultivated fields; and therefore its occurrence in Nova Scotia 

 in similar situations is not by any means a thing to be entirely 

 unexpected.*

Description. — Nova Scotian specimens. Foveoloe of vertex plainly 

 discernible from above as linear depressions; median carina of pronotum not 

 high or sharp, cut somewhat behind the middle, lateral carinse incurved; 

 wing-covers of male usually reaching end of abdomen, and of female usually 

 covering about two-thirds of abdomen, although thej^ may be longer or shorter 

 in each sex; wings sUghtly shorter than wing-covers; hind femora rather 

 slender. • 



Colour. — Nova Scotian specimens. Variable; green, greenish-olive- 

 gray, and brownish colour-phases being found in this province. The diflference 

 between these three phases mainly depends on the colour of the sides of 

 head and of pronotum, which are of one of these tints. There are varying 

 degrees of intensity of these colours, but a number of specimens can be fairly 

 easily placed in the three groups. Descriptions of these phases, from adults 

 taken at Halifax, 14 Aug., 1917, are as follows: — 



Green phase. — Upper part of head, of pronotum, and of abdomen pale 

 vinaceous-cinnamon. Face, sides of head, of pronotum, and of thorax pale 

 chromium-green, which gives this variant its predominant colour. Sides 

 of abdomen vandj'ke-brown. Under parts brownis'i yellow. Often two 

 black lines on upper part of head between eyes; but these sometime.^ wanting. 

 Narrow black line from eye to pronotum, continued on latter as presently 

 described. Lateral carina? of j)ronotum whitish; margined outwardly by a 

 black line (a prolongation of that from the eye), which extends to beyond 

 the middle of pronotum; and mai'gined inwardly by a shorter black line on the 

 posterior two-fifths of the disk. Thus the whitish sinuous line of the lateral 



*Chloeiltis conspena, Harris, the Sprinkled Locust, is not unrommon near dry woodland 

 in New England, north to Maine, and also has been reported from Ont., Man., and .Mb., and 

 miKht pos.sibly be found in so\ithern Nova Scotia. The antennte arc long (10-1^ mm.); 

 male wing-covers well developed, with the scapular area dilated: female win'^-covers usually 

 abbreviated to half length of abdomen, and wings aborted. The males resemble those of 

 Chorthippus curlipeunin but may be distinguished by the absence of the foveolte, the broader 

 black bar on side.") of pronotum, and the larger and more robust body.
