 but distinctly tapering near apex. Lateral carinae of pronotum usually

Dunedin and Key West, Fla., Dec. 12 March 14 (W. 8. B.}. 

 At Dunedin this seaside Tryxalid has been taken only about the 

 middle of Hog- Island, two miles or more from the mainland. 

 There it occurs along the low sandy stretches just inside the bor- 

 der of mangroves which fringe the eastern side of the island. 

 These sandy areas are often overflowed at high tide, and are 

 scantily covered with a species of wire-grass and a fleshy-leaved 

 seaside plant, Rails iiKirilium L. Here the locust and the fiddler 

 crabs flourish together in harmony, the former having been taken 

 on several occasions throughout the winter. In life the females 

 are often a purplish-gray with the numerous black blotches of 

 tegmina standing out prominently and giving the owner a strik- 

 ingly mottled appearance. At Key West the species was abundant 

 in early March in company with O. pelidna among the scattered 

 vegetation growing on the coral rocks northeast of the city. 



As the specific name indicates, C. lialopJiila is, like olircirea, 

 a submaritime species, and is recorded by R. & H. (loc. cit.) from 

 Punta Gorda, Key West and other islands south of Florida ; Cor- 

 pus Christi and Point Isabel, Texas, and Tampico, Mexico. It 

 replaces oil raced, of which it may prove to be only a southern va- 

 riety, along the coasts and on the keys of southern Florida, but 

 occurs in company with it at Corpus Christi, Texas. 



98. OBPHULELLA SPECIOSA (Scudder), 1862, 458. Pasture Locust. 

 Shorter and smaller than pelidna. Ground color either green or 



brown as in that species; tegmina either brown, green or purplish-red,
