SUBFAMILY III. — DUFOURIELLIN^E. 645 



tylus, 2 a little longer than width of head across eyes, 3 and 4 

 slender, sublinear, the fourth slightly longer than third ; pro- 

 notum depressed, its sides toward apex narrowed, broadly 

 rounded, deflexed and with a fine acute distinct margin, its 

 base widely sinuate and median longitudinal sulcus very dis- 

 tinct ; elytra entire, embolium narrow, membrane with four 

 distinct subparallel veins ; femora all slender and fusiform, 

 One palsearctic European species occurs in the eastern states. 



623 (871). Dufouriellus ater (Dufour), 1833, 106. 



Elongate, subparallel. Pieeous-brown to black, glabrous, strongly 

 shining; membrane fuscous, iridescent, whitish toward base; joint 2 of 

 antennae, beak, except basal joint, tibia?, tarsi and middle of under sur- 

 face, dull yellow; femora and genital segment piceous-brown. Antennae 

 finely pilose. Pronotum about twice as wide at base as long, its basal 

 third flattened, minutely transversely rugose. Length, 1.8 — 2.2 mm. 



Willard, N. Car., April 16 (Brimley). Lyon, France (British 

 Mus. Col/.). Heretofore recorded in this country only from 

 New York. In Europe it is said to be gregarious throughout 

 the year beneath loose bark of firs and other conifers. 



VI. Scoloposcelis Fieber, 1863, 61. 



Elongate, subparallel, depressed glabrous species having the 

 head much prolonged in front of eyes ; beak reaching middle of 

 mesosternum ; pronotum trapezoidal, subdepressed, its sides 

 toward the apical angles widely deflexed, finely margined, basal 

 margin widely deeply concave ; elytra entire, embolium narrow, 

 membrane 4-veined ; osteolar channel in our species long, an- 

 gularly curved, not reaching base of metasternal plate ; front 

 and hind femora compressed, strongly dilated, convex above, 

 the front ones armed beneath with several distinct denticles. 

 One of the five known species occurs in our territory. 



624 (872). Scoloposcelis flavicornis Reuter, 1871, 561. 



Elongate, narrow. Dark reddish-brown to blackish-piceous, shining; 

 elytra brownish-yellow, subhyaline, inner margin of clavus, embolium 

 and cuneus piceous or reddish; membrane and inner basal angles of 

 cuneus pale hyaline; apical half of beak, tibiae and tarsi pale brownish- 

 yellow. Antennae thickly pilose with rather long spreading hairs, joint 1 

 reddish-brown, stout, cylindrical, reaching tip of tylus; 2 yellow, visibly 

 thickened toward apex, more than twice as long as 1 ; 3 and 4 dusky 

 yellow, much more slender, subequal in length, united one-half longer 

 than 2. Pronotum with apex scarcely more than three-fifths the width 

 of base; side margins about one-fourth shorter than width of basal one,
