 ponds. Mosholu, N. Y., April 24 (Olsen). Stan Lake, N. Hamp. 

 (Davis). Recorded heretofore only from Quebec, New Hamp- 

 shire and Massachusetts. Resembles interstitial^, but distin- 

 guished by the much larger dark area of elytra, the well denned 

 pale spots of costal area with white spot in the dark area near 

 apex of corium, and the straight margin of pronotum. 



1155 (1320). Saldula littoralis (Linnaeus), 1758, 442. 



Oboval, distinctly widened behind, more so in female. Dull black, 

 opaque, thickly clothed with very fine appressed yellow hairs ; tylus and 

 base of cheeks dull yellow; corium wholly dark, or with a vague pale 

 spot opposite tip of clavus and a row of three or four others between 

 the main nervures; membrane dull yellow, veins deep black, cells each 

 with a vague fuscous spot at base and middle; legs dull yellow, front 

 femora blackish beneath, middle and hind ones as in key; spines and tips 

 of tibiae blackish; joints 1 and 3 of tarsi fuscous, 2 yellowish. Joints 1 

 and 2 of antennae dull yellow, 3 and 4 fuscous-black; 1 slightly shorter 

 than width of vertex, 2 two and one-third times longer than 1 ; 3 and 4 

 subequal, united slightly longer than 2. Length, 5.5 — 7 mm. 



Kent, England (British Mus. Coll.). Recorded in this country 

 from Quebec, New York, Indiana, Illinois, Utah and California. 



IV. Micracanthia Reuter, 1912, 8, 16. 



The members of this genus are distinguished from those of 

 Saldula mainly by the absence of corial veins. They are smaller 

 in size and have the interocular area more narrow; sides of 

 pronotum straight, strongly converging ; elytra conjointly more 

 tectiform ; cells of membrane four, subequal in length. One of 

 the two known species occurs in the eastern states, the other in 

 California. 



1156 (1342). Micracanthia humilis (Say), 1832, 35; I, 360. 



Oval or oblong-oval. Head, pronotum and scutellum black, more or 

 less shining, minutely scabrous, thinly clothed with fine yellow appressed 

 hairs ; clavus and inner portion of corium velvety black, the former 

 usually with a minute white spot near apex, the latter with two similar 

 spots on outer margin and usually a third near middle of apex; embolium 

 or costal area dull white with tip fuscous and an oblong black projection 

 of corium near its middle; membrane dull white with veins and one or 

 two small median spots in each cell fuscous-brown; antennae, except basal 

 joint, beak and apical half of femora dark brown; lower part of face and 

 basal half of femora pale yellow; tibiae and tarsi brownish-yellow, an- 

 nulate with paler. Beak reaching hind coxae. Joint 1 of antennae half 

 the length of 2, 3 and 4 subequal, each slightly shorter than 2. Pronotum 

 with callus of front lobe foveate at middle; hind margin broadly and 

 shallowly concave. Length, 3 — 3.7 mm.
