1. Arctoconsa interrupta (Say). 



Marietta, March: Okefenokee Swamp, June. The southern- 

 most record for this species, which seems to range over the whole 

 United States east of the 100th Meridian. 



2. Arctoconsa nitida (Fieber). 



Spring Creek and Okefenokee Swamp, June. This species 

 appears to range over the Southern Atlantic seaboard from the 

 Gulf to Maryland. 



3. Arctocorisa nitida var. minor (Abbott) n. var. 



Marietta, Athens and Gainesville. This form is very close 

 to nitida, resembling that species in strigil, palas, and general 

 facies. It is however, much smaller {1}/^ — 1}4 mm., -males-, and 

 8 mm., -females-, in length) and differs furthermore in the presence 

 of a pale yellow or clear spot on the outer margin of the tegmina 

 just before the suture that divides the corium from the membrane. 

 This mark, is. rendered more prominent by the presence of a dark 

 brown spot which borders it on the posterior margin. The effect 

 is somewhat reminiscent of the variety bimaculata Guerin, of A. 

 abdominalis (Say). 



4. Arctocorisa hydatotrephes (Kirkaldy). 



Many specimens from Spring Creek, Decatur Co., June. 

 This striking species has not been reported hitherto from else- 

 where than the type locality, Raleigh, N. C. The species is readily 

 distinguished by the coalescence of the tegminal lineations into 

 solid black. In the Georgia specimens, this extends, in most of 

 the individuals, to the pronotum, the typical five lines becoming 

 three by confluence. It is rather remarkable that although abun- 

 dant collections of aquatic Rhynchota have been made throughout 

 the state for several seasons this species appears to be confined 

 to one locality. For this reason the notes of the collector. Dr. 

 Bradley, are of interest. He writes that the region is "more or 

 less of a limestone one and the creek, about 60 feet wide, of perfectly 

 clear water with sandy, or in places rocky, or weed-covered 

 bottoms, is lined with cypress and live oak and scrub. But at 

 intervals along the creek are cypress bays, where the growth of 

 cypress and deciduous trees and the consequent shade is very 

 dense, where the ground is frequently overflowed with water, 

 leaving on its retreat such pools as the hydatotrephes occur in."
