THE GROUND OR BURROWER BUGS. 89 



Taken by sweeping low herbage along roadsides and in waste 

 places. Ranges from Massachusetts west to Nebraska. Prob- 

 ably confused in many collections with pusillus which super- 

 ficially it closely resembles. Hart records it from several sta- 

 tions in different parts of Illinois, April 18 — Dec. 4. Stoner 

 swept it in June from plantain-leaved everlasting, Antennaria 

 plantaginifolia (L.), near Iowa City, la. 



51 ( — ). Amnestus subferrugineus (Hope), 1837, 19. 



Ob'.ong, subconvex. Head and scutellum dark reddish-brown, pro- 

 notum chestnut-brown, its margins paler; elytra, legs and beak brown- 

 ish-yellow; under surface chestnut-brown, the sterna and ventrals 4 — 6 

 paler. Antenna? piceous-black with yellowish hairs, joint 2 very small, 

 only about one-sixth as long as 3, the latter one-half longer than 4, 5 fusi- 

 form, more slender than either 3 or 4. Pronotum with sides straight 

 from base to middle, thence broadly curved to apex; disk with two trans- 

 verse subapical rows of coarse punctures, the elevated area behind them 

 finely and sparsely punctate; basal third coarsely and thickly so. Corium 

 sparsely and coarsely punctate, its outer apical angle not reaching tip of 

 abdomen. Ventrals minutely punctate, rather thickly and finely pubes- 

 cent. Length, 2.5 — 2.7 mm. 



Royal Palm Park, Fla., Dec. 9 ; two specimens sifted from 

 vegetable debris by the side of picnic table. A neotropical 

 species described from St. Vincent's Island and not before re- 

 corded from this country. Prof. H. G. Barber, who identified 

 them for me, states (Ms.) that he has seen a number from 

 Porto Rico. 



IX. Sehirus Amyot & Serville, 1843, 96. 



Small broadly oval, subdepressed species without marginal 

 cilia?, having the head declivent, longer than wide, its apex 

 rounded ; cheeks equalling or slightly longer than tylus, their 

 margins narrowly reflexed, not ciliate or toothed ; antennae 

 slender, surpassing base of pronotum, their joints gradually 

 slightly increasing in length ; beak reaching middle coxae, 

 joints 2 and 3 subequal, 4 shorter ; pronotum one-half wider 

 than long, sides feebly curved and converging from base to 

 apex, front angles obtuse ; scutellum equilaterally triangular, 

 its tip depressed, bluntly rounded ; elytra broad, the apex of 

 corium subtruncate ; membrane reaching tip of abdomen, its 

 veins few and very fine ; osteolar opening continued as a long 

 shallow curved canal, reaching nearly to outer end of meta-
