 der, subequal, beset with long hairs, each about four times the length 

 of 1. Pronotum with disk thickly, very finely punctate, each puncture

III. Corixidea Reuter, 1891, 17. 



This genus differs from Schisoptera mainly by the characters 

 given in key. The ocelli are present but minute ; scutellum with 

 disk flattened, margins slightly elevated, apex narrowed; elytra 

 entire, the costa thickened and rounded, not flattened, the first 

 and second costal cells subequal in length (fig. 13) ; suture be- 

 tween propleurum and pronotum extending straight back be- 

 hind eye (fig. 12) ; inner hind angle of metapleurum produced 

 as a rounded lobe. One of the three known species occurs in 

 the eastern states, the others in Panama, Central and South 

 America. 



627 (— ). Corixidea major McAtee & Malloch, 1925a, 26. 



"General color blackish, the heavily chitinized portions of upper sur- 

 face with copious bluish-gray pubescence, that on head longer than in 

 lunigera (a Brazilian species), more hyaline portions of fore wing 

 bluish-cinereous; legs brownish-testaceous. Head and pronotum as seen 

 from side and venation of fore wing as in figs. 12 and 13. Distance be- 

 tween eyes across back of head about twice the width of one of them; 

 veins of clavus neither thickened nor long haired ; no conspicuous pale 

 markings on fore wings. Length, 1.25 mm." 



The above is a copy of the original description including parts 

 of the key leading up to it. Described from a single specimen 

 taken at light in August at Clarksville, Tenn., and now in the 

 U. S. National Museum.
