1086 FAMILY XL. — CORIXID^E. 



at the Park. A handsome, well marked little species, and the 

 only Corixa with pale basal claval area as in A. edit! is (Champ.) 

 and ./. mercenaria (Say). 



1251 (1464). Corixa sellaris Abbott, 1913, 85. 



Elongate, slender; pronotum and clavus minutely rastrate. Head 

 yellowish-white, vertex fuscous; pronotum triangular, with 12 dark 

 brown lines, these curved, parallel, almost entire; elytral markings every- 

 where vermiculate and anastomosing, forming a continuous interlocking 

 pattern over clavus, corium and membrane, with little tendency toward 

 cross-barring or arrangement in rows; embolium fuscous; legs and 

 under surface ivory-white. Female with pala compressed, broadly 

 joined to tibia, two-fifths as wide as long. Length, 5 mm. 



Known only from females taken at several stations in 

 Georgia. 



1252 (1469). Corixa burmeisteri Fieber, 1851a, 24. 



"Blackish-fuscous with yellow lines; head yellow, vertex acutely 

 angulated; pronotum short, posteriorly rectangular, with margins and 

 seven or eight straight cross-lines fuscous ; elytra narrow with pale 

 lines wide, unequal, forked, crossing over onto membrane, where they 

 are horizontal and acutely angulate or undulate; embolium sordid, with 

 several lines or a spot toward apex blackish; legs and under surface 

 pale. Male with frontal impression obovate, scarcely surpassing eyes; 

 pala obliquely ovate, acute, base beneath produced in an angle. Length, 

 4 mm." (Fieber). 



The above is a free translation of the original description, 

 the types being from "America boreali." 



1253 (1440). Arctocorixa laevigata (Uhler), 1893a, 384. 



Chestnut-brown. Pronotum very convex, highly polished, not ras- 

 trate, its disk with a percurrent median carina and crossed by 14 — 15 

 yellow lines, these sometimes split at or before the middle, the basal ones 

 narrower. Yellow cross-lines of clavus interrupted, the inner series zig- 

 zag; those of corium in short, wavy, subdiagonal rows. Male with 

 frontal impression ovate, very shallow, reaching slightly above the line 

 of eyes; pala broad, cultrate, apex above bluntly rounded, lower apical 

 angle subacute. Length, 10 — 11.5 mm. 



Described from Utah and California. Recorded by Hunger- 

 ford (1925a, 142) from Rhode Island, New Jersey and Mary- 

 land. The non-rastrate carinate pronotum with 14 — 15 pale 

 cross-lines will distinguish this species from the other members 

 of its group.
