October, 1913 Bulletin of the Brooklyn Entomological Society 87 



Femur narrowed distally, its distal width about 73 its basal 

 width, the outer edge convex, the inner somewhat concave, the 

 stridular area confined to the proximal half of its surface. Length 

 of tibia between articulations, -/s of that of pala. Posterior tarsi 

 dusky. Legs and under-surface pale. Strigil sinistral, minute, 

 ovate, transverse, with 3 striae. Length ?>% mm., width 1 mm. 

 Holoiype: a male from Thalman, April. Paratype from 

 Offemian. 



Female: paler than the male, interocular width about the 

 same. Pronotal lineations 5, straight and unbroken. Claval 

 lineations slightly effaced on the inner angle. Body pale beneath. 

 Palae cultrate about 5 times as long as high. First tibia % as 

 long as the pala. 



Allotype: from Thalman, April 28. 

 v5 . Corixa verticalis (Fieber) . 



Two males, three females from Athens, Thalman and Darien; 

 April. The fovea conspicuously surpasses the eye in the males in 

 the collection, but in the absence of other material this seems 

 hardly warrant for a specific distinction. The two kinds of teg- 

 minal hairs which Fieber describes for verticalis, pigmcea, and 

 burmeisteri, and which Kirkaldy thought sufficient for subgeneric 

 distinction (Trichocorixa) is not a constant character. In the 

 Georgia specimens it is present in the females and absent in the 

 males. Palar pegs 13-14, in a strongly arched row, the distal 3 to 

 6, longer and sharper than the rest. Strigil sinistral, curved, 

 transverse, long and ribbon-like, about 25-30 striae. 

 16. Palmacorixa buenoi (Abbott). 



One female from Oglethorpe, July. This species ranges along 

 the length of the Atlantic seaboard from the Gulf to New England. 



Artificial Key to the Corixidae of Georgia 



No one is more painfully aware of the deficiences of these tables than the 

 author. The females are particularly difficult to identify by a single character 

 and large series are necessary to properly appreciate the specific differences. 

 It is hoped, however, that the synopsis, combined with the descriptions, will 

 enable anyone to identify his species at least so far as the males are concerned. 

 It should not be concluded that because a specimen does not fit into the key, 

 it is necessarily new. Arctocorisa altentata (Say) has been inserted since it is 

 very likely to be found in the region.
