SUBFAMILY I. TRYXALINJ2. 231 



correspond so closely to the dead leaves which cover 

 their haunts of the summer months. The green back- 

 ed males are, however, the prevailing- form of that 

 sex at all seasons. The long-winged form has not, as 

 yet, been taken in Indiana. The wings of the other 

 form are too short for flight, and it tries to escape 

 when disturbed only by leaping clumsily. 



In Florida it is also common,, having been taken 

 by me at Sanford, Lakeland, Sarasota and Dunedin 

 and recorded from numerous stations on the main- 

 land as far south as Fort Myers, Citrus Center and 

 Palm Beach. About Dunedin both nymphs and 

 adults are found throughout the winter, usually 

 along the margins of ponds and wet depressions in 

 old fields and open pine woods. There the brown 

 form of the male occurs more plentifully than in 

 Fig. 86. Female. Indiana, and pairs have been noted mating in 



X 1-5. (After 



Lugger.) December. 



North of Florida the known range of D. viridis extends from 

 Massachusetts and southern New Hampshire, west to Minnesota 

 and middle Nebraska and south and southwest to northwestern 

 Arkansas, central Oklahoma and Houston, Texas. It has not 

 been recorded from Canada nor from Michigan, though it doubt- 

 less occurs in the southern part of that State. The long-winged 

 form, punctulata Scudder (1862, 455) appears to be very scarce 

 outside of New England, and is apparently confined to the female 

 sex. Morse (1896, 383) reports that out of 330 New England 

 adults in his collection 20 are macropterous females with teg- 

 mina averaging 19 mm. in length, five being brown and 15 green; 

 the others all brachypterous, 13 males and 43 females being of the 

 brown and 147 males and 107 females of the green phase. The 

 brown form is the Chlnealtis Intuited Scudder (1875g, 510) de- 

 scribed from Dallas, Texas. The Tnucalis anyusticornis Stal 

 (1873, 105) described from South Carolina is also a synonym. 



When the late spring and early summer have been more than 

 usually damp in Indiana, hundreds of dead and dying specimens of 

 D. riridis and of Mchinoplus birittcitus (Say), are often to be 

 seen in late July in the tops of iron weeds. They are principally 

 females, and their death is probably due to the insect fungus, 

 Entomophthora caloptcni Bessey, an interesting account of which 

 appeared in Bull. 22, U. S. Dept. Agr., 1890, 104. The disease is, 

 perhaps, more abundant on account of the young being exposed
