activity in escaping when alarmed by seeking hiding places under 

 the scrub palmettoes, to which they hurried with seeming un- 

 gainliness but nevertheless considerable speed." 



Part of Scudder's types were from North Carolina and the 

 known range of yibbosns extends from that State to Dnnedin, 

 Fla., and inland to Warm Springs, Ga. It occurs from sea level 

 to about 2,000 feet in elevation and is chiefly found among the 

 wire-grass and dead leaves of oak and pine woods. 



This is the largest of our species of Atlantic us and the males 

 may be readily known by the large size taken in connection with 

 their concealed tegmina and long tooth of cerci, while the fe- 

 males are distinguished mainly by the size, obtuse lateral carime 

 and long, strongly rounded posterior lobe of pronotum.

"Coriicolor, lateribus omnino fuscis, pronoto macula in sinu flava; 

 vertice pedibusque griseo-fuscis, tibiis extus dilutioribus. Male elytris 

 sub pronoto absconditis. Long. corp. 11"' (22.9 mm.); femor post 1". (25.4 

 mm.)" (Burmeister.) "Male with tegmina projecting very slightly can- 

 dad of the caudal margin of pronotal disk; cerci short, robust, the distal 

 portion moderately acute (Fig. 195, k ) ; subgenital plate slightly acute-an- 

 gulate emarginate. Female with subgenital plate deeply and broadly 

 emarginate, tips of lateral sections well rounded (Fig. 194, g] ; ovipositor 

 straight, but little more than two-thirds the length of caudal femur. Length 

 of body, $, 25.4, $, 25.7; of pronotum, $, 10.7, 9, 12.2; of hind, femora 

 $ , 24.3, $ , 29.8; of ovipositor, 20.6 mm." (7?. & H.) 



The original description of Burmeister was of a single male 

 from South Carolina in the Germar collection. R. & H. ( lOlOa, 87) 

 assigned the name to one adult pair and some nymphs taken at 

 Billy's Island and Thomasville, Ga., stating that they have ar- 

 rived at their conclusion "by a process of elimination, 1 ' since they 

 feel certain that it must occur in eastern South Carolina and 

 that it is the only species found anywhere near that agrees with 

 the particular character given by Burmeister of having the teg- 

 mina of male hidden under the pronotum, etc. 



Known definitely only by an adult male from Billy's Island 

 and a female from Thomasville, Ga., and some nymphs from the 

 latter place and Jacksonville, Fla. At Thomasville they were 

 found among the wire-grass in damp areas in the pine woods. 



The present status of the dorsaUs of Burmeister is, in my 

 opinion, the same as that of his par-lti/mcms, i. e., an open ques- 

 tion. From a truly scientific basis the evidence cited by R. & H. 

 in both cases has little value, as they have seen specimens of 

 neither from South Carolina. However, for the time being, the
