5. Arctocorisa compressa (Abbott). 



Numerous specimens from the Okefenokee Swamp. June. 

 Also from Wrens, Gainesville, Cave Springs and Blackshear. 

 May, June. 



6. Arctocorisa sigmoidea (Abbott). 



Numerous specimens from Okefenokee Swamp, June. Also 

 from Blackshear, Gainesville and Marietta. Apparently the 

 most abundant species in southern Georgia. The males are very 

 easily identified by the peculiar palse, but the females resemble 

 those of A. compressa so closely that in individual cases it is often 

 very difficult to discriminate them. Sigmoidea is somewhat 

 narrower and smaller than compressa, more shiny and less ras- 

 trate. Compressa is much less abundantly represented in the 

 present collections. 



7. Arctocorisa hradleyi (Abbott). 



Okefenokee Swamp, June. Blackshear, May; Cave Springs, 

 August; Offerman, April. 



8. Arctocorisa scabra (Abbott). 



Okefenokee Swamp, June; Marietta, March. 



9. Arctocorisa signata (Fieber). 



Gainesville, April. Several specimens that are without 

 question Fieber's species, although differing in minor particulars. 

 The male fovea is rather narrowed between the eyes. The strigil 

 is dextral, oblong, twice as wide as long 

 (width 0.1 mm.) with 4 striae. The palae 

 in the male are held in a peculiar fashion, 

 bent down until they almost touch the 

 femur. Whether this is a constant charac- 

 ter or not is impossible to say. The male palae are thin, strongly 

 wraped inward, short cultrate and about }4 longer than the 

 somewhat narrower tibia. The pegs are stout, 13-14 in number 

 and follow the upper margin for the distal half of the row, the first 

 half-dozen pegs being somewhat below the upper margin. 



10. Arctocorisa pectenata (Abbott), new species. 



Head rounded, dull yellow. Interocular width a little less 

 than the length of the head, and not quite three times the width 

 of the head. Fovea shallow, long and rather narrow. Pronotum
