Eadinotatum brevipenne (Thomas). 



This interesting and peculiar species is mainly a common inhabitant 

 of pine woods in Thomas and Leon counties. It lives among the dried 

 needles and apparently depends for safety more on protective resem- 

 blance and coloration than on anything else, as the saltatorial powers 

 are limited and the flight organs useless. Three color types are repre- 

 sented in the series of one hundred and eleven specimens examined, 

 one type being uniform brownish of varying shades, another brownish 

 with the dorsal surface of the head, pronotum and tegmina grass green, 

 and the third brownish with the lateral aspect greenish. From the 

 material examined it would appear that around Thomasville the species 

 is represented by mature individuals in late spring and early summer 

 (April to July), September individuals being extremely small, while 

 a large number of November, December and March specimens show a 

 gradu^ increase in size. The peculiar character of the subgenital 

 plate of the male is pronounced in specimens taken in November. 

 Color notes from life: Green phase, nymph, Thomasville, Georgia, 

 November 30, 1903 ; color of the dorsal surface, antennae, eyes, mandi- 

 bles, labrum, median and anterior limbs, posterior tibiae and tips of the 

 posterior femora wood brown; lateral aspects, face, meso- and meta- 

 sternum and posterior femora (except the distal portions) apple green. 

 Brown phase, nymph, Thomasville, Georgia, November 30, 1903; gen- 

 eral color wood brown, obsciu^ely and rather irregularly lined and spot- 

 ted with broccoli brown, a rather distinct postocular and pronotal 

 streak being developed; posterior femora with the apical portions 

 blackish. The color of adult males is grass green on the dorsal surface 

 of the pronotum and tegmina, the abdomen, lateral aspect and dorsal 

 surface of the femora as in the immature ; inferior margin of the lateral 

 lobes of the pronotum pale ochraceous. The adult female is uniform 

 wood brown, except the eyes, which are umber obscurely spotted with 

 darker brown. One adult female, however, has a green and brown 

 coloration, but the pattern is exactly the reverse of that found in the 

 males, the green being lateral instead of dorsal. Several specimens 

 examined are strongly overcast with blackish spots. 



I noticed many immature specimens of this species pale straw brown 

 in color, and one or two specimens taken were profusely marked with 

 small black dots. On April 7, 1904, I noticed several mature males of 

 this species in the sprouting broom sedge at the edge of the golf course 

 near thick woods. Returning to this place two days later, I took a 

 number of mature males and several females almost adult. These 

 males were nearly all of the green form, while the females were entirely
