THE WATER-BOATMEN. 1077 



(Brimley). Staten Island, N. Y., Oct. 5 (Davis). Its recorded 

 range extends from New England west to Illinois and south- 

 west to Missouri. Van Duzee includes Florida and cites a 

 Barber reference which is incorrect. The entire, subparallel, 

 pale and dark cross-bars of clavus, strongly rastrate upper sur- 

 face and numerous pegs of male pala distinguish this from its 

 allies. 



1228 (1444^). Arctocorixa parshleyi Abbott, 1916, 342. 



Color as in key; pronotum with eight or nine pale cross-lines; pale 

 lineations of clavus broad and entire; those of corium confused and inter- 

 rupted, not longitudinally seriate. Male pala as in fig. 12, the pegs 

 29 — 30, placed along the upper margin. Strigil square, small, with six 

 cross striae. Length, 6.5 mm. 



Pittsburgh and Greensburg, Pa. (Wirtner). Recorded from 

 Maine, Rhode Island and New York. Closely allied to alternata 

 (Say).

Dark fuscous bi'own; eyes black; pronotum with six or seven blackish 

 cross-bars with much narrower yellow lines alternating; basal third of 

 clavus with regular oblique dark bars and pale lines; remainder of clavus 

 and corium with short zigzag yellow marks arranged in three somewhat 

 regular longitudinal rows; pale marks of membrane obscure; head, legs 

 and sterna dull yellow; embolium, setae of hind tibiae and fringe of hind 

 tarsi, fuscous; ventrals dusky. Vertex of head with a short median 

 carina. Pronotum lenticular, its hind margin obtusely rather broadly 

 rounded; disk strongly rastrate, the apical third with a short obtuse 

 median carina. Clavus and corium much more finely rastrate. Male 

 with frontal impression narrow, reaching middle of eyes; pala short,

 the narrower tibia; pegs 13, in a regular row. Length, 5 — 5.5 mm.

 throughout the winter in ponds near Dunedin ; not before re- 

 ported from Florida. Lakehurst, N. J., and Staten Island, 

 N. Y. (Davis). Recorded from Pennsylvania, Illinois and 

 Georgia. The fuscous -brown hue, rows of pale zigzag mark-

 the chief distinguishing characters.
