No. l6.] ORTHOPTERA OF C;ONNECTICUT. 9I 



as they grade into each other, only two forms are usually 

 recognized, the green form, virginiana, and the brown form, 

 infuscata. Many of the females can be referred to the green 

 form while the majority of the males are brown. Virginiana 

 usually has the head, pronotum, and outer face of hind femora 

 bright green with a broad stripe of the same color along the 

 basal two-thirds of the outer edge of the tegmina. The re- 

 mainder of tegmina is light brown, and the abdomen reddish 

 brown. In the brown form the tegmina are more or less mottled 

 with light and dark brown. The inner wings of both forms are 

 transparent, yellowish at the base, with the apical two-thirds 

 smoky, becoming paler at apex ; along the middle of the front 

 margin is a dark bar. Hind tibiae pale to dark brown, often 

 with a pink, purple, or bluish cast, and with more or less distinct 

 black bars on inner face which often show on the upper outer 



groove.

This species passes the winter in the nymph stage and the 

 adults appear during the last of April, being the earliest as well 

 as one of the most common of our springtime locusts. It is 

 scarce during August, but is found from September until frost. 

 It occurs throughout the state.
