1157 (1321). Lampracanthia coriacea (Uhler), 1872, 421. 

 Elongate-oval, male; broadly oval, female. Black or piceous-black, 



shining; head, pronotum and scutellum minutely scabrous; antenna? pice- 

 ous-brown, the second joint sometimes paler; femora in great part pice- 

 ous, female, largely yellow, male; coxa?, tibia? and tarsi brownish-yel- 

 low with tips and spines piceous. Beak 

 reaching hind coxa?. Antenna? with scat- 

 tered bristles, joint 1 stout, subclavate, 2 

 slender, nearly three times as long as 1, 3 

 and 4 subequal, stouter than 2. Pronotum 

 subtrapezoidal, side margins flattened and 

 reflexed to apical third, then evanescent 

 and deflexed; front lobe twice as long as 

 hind one, its callus large, foveate at mid- 

 dle; hind margin broadly very shallowly 

 concave, its lobes obtusely angled. Scutel- 

 lum large, its middle broadly and shal- 

 lowly concave. Elytra at base not much 

 wider than base of pronotum, thence 

 broadly curved with margins wide and 

 reflexed to apex; disk vaguely coarsely 

 and sparsely punctate, its divisions feebly 

 x 6. (After Lugger). differentiated; membrane relatively small, 

 declivent, of much the same texture as corium. Sixth ventral, female, 

 obtusely triangular, convex, covering the genitals, its side margins 

 sinuate and apex broadly rounded. Genital plate of male obovate, 

 strongly convex, clothed with rather long yellow hairs. Length, 6 — 7 

 mm. (Fig. 203). 



Steuben, Kosciusko and Marshall counties, Ind., June 5 — July 

 6 ; taken in numbers beneath logs at the edge of a marsh near 

 Lake Tippecanoe (W.S.B.). Long and Staten Island, N. Y., 

 May — July (Davis). It is a species of the Transition Life Zone, 

 ranging from Ontario and New England west to British Colum- 

 bia, Colorado and Utah. Not recorded south of New Jersey. 

 Where found it occurs along the margins of tamarack bogs 

 and marshes, either beneath cover or running about between 

 the roots of sedges and grasses. 



1158 (1322). Lampracanthia anthracina (Uhler), 1877, 438. 



Narrowly oval. Color of coriacea; antenna? dull yellow at base, 

 dusky beyond; legs wholly yellow, the last joint of tarsi and tips of tibia 

 dusky. Interocular area and pronotum narrower than in coriacea, the 

 latter subconical, its front lobe less convex, three times as long as hind 

 one. Joint 2 of antenna? twice as long as 4, slightly shorter than 3. 

 Scutellum flat, its basal half distinctly irregularly rugose. Elytra con- 

 jointly oval, strongly convex, "arched and decurving over the body like 

 the shell of a terrapin" (Uhler) ; clava and coria distinct, surface im-
