Long Key, Fla., July 13, 1912: 1 n. 



Big Pine Key, Fla., July 6, 1912; 2 n. 



Key West, Fla., July 3-7, 1912; 4 n., 1 ootheca. 



The individuals from Homestead and Detroit are in the instar 

 preceding maturity, while the others represent three less developed 

 stages. 

 Gonatista grisea (Fabr.). 



Key West, Fla., July 3-7, 1912; 3 c^, 4 9 , 9 n. 



The nymphal individuals are in four stages of development, the 

 most immature specimen having the body 8.25 millimeters in length, 

 the same measurement in the largest nymph being 39 mm. The 

 males show but little variation in size, all, however, equalling or 

 exceeding the maximum measurements given by Caudell for this 

 form. ^5 The females show some size variation, the length of the 

 pronotum in all being slightly longer than Caudell's measurements, 

 although the tegminal length is under his maximum in all four 

 individuals. The coloration of Ijoth sexes shows no decided varia- 

 tions. Specimens from more northern localities in the range of the 

 species apparently average smaller than individuals from the keys, 

 judging from a male from Tarpon Springs, Fla., and two females from 

 Fort George, Fla., and Thomasville, Ga. 



The present specimens were taken chiefly from gumbo-limbo trees 

 in the heavy key scrub jungle, but the species also occurred on sea 

 grape. The insects were always on the trunks or branches and 

 generally about six feet from the ground, infrequently higher and 

 very rarely lower. They were perfectly protected when in their 

 resting position, being then closely pressed against the bark of the 

 tree. When disturbed they would make off with a rapid scuttling 

 run. 

 Thesprotia graminis (Scudder). 



Homestead, Fla., July 10-12, 1912; 1 d', 2 9. 



Big Pine Key, Fla., July 6, 1912; 1 cf , 2 n. 



Key We.st, Fla., July 3-7, 1912; 2 9 , 4 n. 



The nymphs are in three stages of development, the least mature 

 being from Big Pine Key, taken the same day as an adult female- 

 From this it would appear that the species matures over a consider- 

 able part of the year. 



At Homestead the females of this species were taken in the under- 

 growth of pine woods, while the male was found dead in a spider's 



15 Psyche, XIX, p. 161 (1912).
