Mantidce is Stagmomantis Carolina and its favorite habitat is a black- 

 berry bush or other low growth, occasionally in the pine woods, but 

 more often in branches and fields. The slender Thesprotia graminis 

 is a purely pine woods species, and is found among the wire-grass, 

 where it is so well protected by both form and coloration as to almost 

 defy detection. In the spring Conocephalus appears in numbers in the 

 broom sedge and other grasses throughout the pine w^oods. The 

 Gryllidce in the fall before the frosts is represented by a few species, 

 of which Nemobius ambitiosus is most plentiful, and it may be found 

 in diminished numbers throughout the winter. Under rubbish Gryllus 

 are common, and Orocharis gryllodes may be found hibernating under 

 signs on oak trees. During the spring, in certain restricted localities, 

 Falcicula hehardi is quite plentiful among the wire-grass, and later in 

 the summer Hapithus brevipennis, while OEcarithus appears frequenting 

 1he bushes and shrubs, especially those growing on the sides of the 

 branches. The Orthoptera found in these branches differs greatly 

 from that of the pine woods. Here in the late fall hardly anything is 

 to be found except Nemobius carolinus and exiguus which are plenti- 

 ful, the former in beds of sphagnum only; and some Paroxya floridiana 

 restricted to a few sunny spots. In the spring, however, Tettigidea 

 lateralis is very common in all grassy spots, and in certain localities 

 Tettigidea spicata is found. In other locations Acrydium arenosum, 

 Paratettix texanus and Neotettix femoratus may be taken, the best 

 places being where these streams empty into a lake or flow through 

 low sandy stretches of fields. The species of Acrididoe found in the 

 fields just before the heavy frosts are Chortophaga viridifasciata, 

 Melanoplus propinquus and Orphulella pratorum, all in great numbers; 

 Psinidia fenestralis, Melanoplus atlanis and Spharagemon ivyomingi- 

 anum are moderately common earlier but soon disappear, while Dichro- 

 morpha viridis, which swarms in the summer, is not in evidence. 

 Among the species found during the summer months are Hippiscus 

 phoenicopterus, H. riigosus, Spharagemon bolli, Dissosteira Carolina, and 

 Trimerotropis citrina.

This species is apparently not uncommon at Thomasville, as speci- 

 mens were taken May 2, 21, 26 and 29; August 12, and a series of eight 

 the first week in October, 1903. These individuals are indistinguish- 

 able from Cuban specimens, and exliibit considerable variation in 

 size, but'in color are quite constant.
