1006 FAMILY XXXIII. — SALDIDjE. 



shorter than 3, much longer than 1. Pronotum as in signoreti, the callus 

 of front lobe impressed at middle. Other characters as in key. Length, 

 5.5—6 mm. (Fig. 2026). 



Raleigh, N. Car., April 29— Nov. 19 (Brimley). Plummer's 

 Island, Md., Oct. 28 (Gerhard). Described from Indiana. 

 Ranges from Quebec and New England west to Manitoba and 

 Minnesota, and southwest to North Carolina. Uhler (1877, 

 433) calls it: "A sprightly species which inhabits uncovered 

 dark rocks in the beds of running creeks and brooks. It flies 

 from rock to rock and from its wariness and activity is quite 

 difficult to capture." 



1143 (1334). Pentacora sphacelata (Uhler), 1877, 434. 



Elongate, subelliptical. Above dull clay-yellow, tinged with dusky; 

 vertex, middle of front lobe of pronotum and base of scutellum, blackish; 

 elytra with part of disk and the membrane and veins fuscous; antennae, 

 beak, tibia? and tarsi brownish-yellow; femora paler, mottled with pur- 

 plish dots; under surface usually in great part black, shining, proster- 

 num and meso- and metapleura pale yellow. Joint 1 of antennae shortest, 

 subclavate, 2 longest, subequal to 3 and 4 united, 4 one-third shorter than 

 3. Beak reaching between hind coxae. Pronotum short, the callus of 

 front lobe sharply defined both before and behind by an impressed line 

 of fine punctures; hind margin less deeply concave than in allied species, 

 the humeral angles less prolonged, their tips subtruncate. Length, 

 5 — 6 mm. 



Ft. Myers and Marco, Fla., April (Davis). St. Augustine, 

 Fla., January (Gerhard). A submaritime species occurring 

 along the beaches of the Atlantic and Gulf coasts from Mas- 

 sachusetts to Texas. Uhler (1877, 435) mentions it as: "Ex- 

 ceedingly abundant on the discolored sandy and marshy brown 

 spots of the tide-water districts of Massachusetts and Mary- 

 land. The salt mud seems to afford them the conditions best 

 suited to their development in unnumbered multitudes." The 

 dull clay-yellow hue and short setae of elytra readily distinguish 

 this form from its allies. 



1144 (1317). Pentacora hirta (Say), 1832, 34; I, 359. 



Elongate-oval. Color above dull straw-yellow; a narrow forked 

 median stripe between the eyes, the large median callus of front lobe 

 of pronotum, three spots on hind lobe, scutellum except apex, and elytra 

 except embolium, dark brown, shining; membrane fuscous, paler toward 

 apex; under surface brown, thickly pubescnt; prosternum and legs yel- 

 low, the latter thickly hirsute with erect dark hairs, the tibiae with black 

 spines. Antennal joints 1 and 2 dull yellow, the others darker, all beset 

 with similar hairs, joints 3 and 4 subequal, united slightly longer than 2. 

 Beak reaching hind coxae. Pronotal collar with a transverse row of fine
