Eremocoris Fieber. 



E. ferus (Say). (PI. xvi, 26.) 



Het. New Harm., 16, 1832. 



Head, anterior lobe and four fasciae on the posterior lobe of 

 pronotum and scutellum piceous black. Lateral expansion of the 

 pronotum, especially at the sinus between the lobes and nearly the 

 anterior half of the hemelytra conspicuously pale. Three fasciae 

 on posterior lobe of pronotum, posterior half of hemelytra dark 

 castaneous. The membrane is brown with a conspicuous white 

 spot at the outer basal angle and another opposite to it at the inner 

 apical angle, sometimes also pale at inner basal angle. The femora 

 are dark brown, with the tibia a little paler, the fore femora pro- 

 vided with a single enlarged preapical spine preceded and followed 

 by several minute teeth. About 6 mm. long.

Scolopostethus Fieber. 



Three species, resembling small Eremocorids, occur in the east, 

 all measuring around 3-3.5 mm. These are found commonly by 

 sifting among dead leaves in damp situations. 



Key to Species. 



1. Hemelytra strongly fasciate with fuscous posteriorly, with surface 



of membrane often variegated with pale 2 



Hemelytra not strongly fasciate with fuscous posteriorly, merely 

 slightly embrowned. Membrane in both forms uniformly em- 

 browned, surface not variegated with pale but with a conspicuous 

 pale spot at outer basal angle and another at inner apical angle, 

 with the inner basal angle sometimes pale. Lateral edge of pro- 

 notum nearly straight. Antenna with extreme apex of second, 

 apical half of third and all of fourth segment embrowned. All 

 femora pale. Fore femora with a single large spine nearer to 

 middle than apex between which and apex are five or six minute 

 teeth diffidens 



2. Membrane marked with the white spots as in preceding, surface in 



the middle often more or less pale between the veins. Lateral 

 edge of the pronotum nearly straight. Antenna with all of fourth 

 and all of third except extreme base, embrowned. All femora _ 

 most commonly pale with fore femora armed as in diffidens atlanticus 

 Membrane pale between the dark veins, without conspicuous pale 

 spots at the angles in either form. Lateral edge of pronotum 

 obviously concave. Antenna with apex of second, all of third 

 and fourth segments embrowned. Most commonly fore femora 

 more or less and posterior femora before apex, dark brown. Fore 

 femoral spine preceded and followed by a few minute teeth thomsoni 



S. diffidens Horvath. 



Revue d'Ent, xii, 240, 1893. 



Very distinct by reason of the less strongly contrasting colors 

 of the hemelytra. Occurs commonly in both short and long- 

 winged forms.
