Elongate, sides subparallel. Above pale yellow, shining; pronotum 

 with nine or ten narrow transverse black lines, alternating with similar 

 yellow ones; black markings of clavus narrow, oblique, in part anasto- 

 mosing, often forked on the ends; those of corium and membrane similar 

 but less oblique; lower front of head and under surface dull white, im- 

 maculate. Male with frontal depression very large, covering nearly the 

 entire face and projecting above the eyes; pala as in fig. 18, scarcely 

 longer but distinctly broader than tibia, its apical half deflexed, obliquely 

 truncate, pegs as in key. Female with head darker, its front convex. 

 Vertex obtusely longitudinally carinate in both sexes. Other characters

Marion Co., Ind., Aug. 16 — Oct. 7 (W.S.B.). Agricultural 

 College, Miss. {Weed). In Marion County it occurs frequently 

 among the clumps of water-willows, Dianthera americana L., close 

 to the edge of running water ; also in the stagnant waters of 

 woodland ponds. Recorded definitely heretofore only from 

 New England, Pennsylvania, Michigan and Georgia. Easily 

 known from our other species by its larger, more robust form 

 and the very large frontal depression of males, the apex of 

 which projects above the eyes. 



1247 (1447). Corixa reticulata Guerin, 1857, 423. 



Elongate, slender, sides subparallel. Color as in key; cross-lines 

 of pronotum crowded, the nine or ten pale ones sordid white, with two 

 or three of the median ones united near the ends; clavus with basal 

 eight or ten dark lines regular, parallel, narrower than the pale inter- 

 vals, slightly widened and in part forked at the ends ; apical two-thirds 

 of clavus and all of corium and membrane with short vermicular or 

 undulate pale markings, evenly distributed; embolium yellowish, its outer 

 margin fuscous; legs and under surface wholly pale. Vertex as wide as 

 eyes with a row of fine punctures each side, and an obtuse median carina 

 prolonged backward as a cusp. Pronotum convex, triangular, minutely 

 rastrate, its hind margin obtuse-angled. Male with frontal impression 

 deep, elliptical, reaching between apical third of eyes; pala as in key, 

 tibiae prolonged over its basal third. Female with front strongly con- 

 vex, hind tarsi fuscous. Length, 4.5 — 5 mm.
