margins, almost twice as broad as long ; the anterior angles broadly 

 prominent, ronuded ; lateral margins oblique ; posterior margin sub- 

 truncated; the surface variolosely punctate behind the middle, somewhat 

 so on the anterior margin, and more densely on the sides ; anterior part 

 of the disk to behind the middle highly polished ; the punctate surface 

 and lateral margin invested with remote, long, rust-brown hairs, those 

 of the sides longer. Scutellum almost as broad as long, remotely and 

 more finely punctate, becoming finer posteriorly, with remote, long, 

 rust-brown hairs. Sides of the prosternum anteriorly a little raised into 

 flat lobes ; medio- and post-pectus coarsely, remotely punctate. Corium 

 broad, broader behind, finely, remotely, obsoletely, on the exterior area 

 more densely and deeply, punctate, with remote long hairs ; the lateral 

 edge densely hirsute ; membrane brownish. Legs rufo-piceous ; the 

 tarsi ferruginous and very slender, the intermediate joint very small; 

 anterior femora on the upper side and exterior to the middle line with 

 a series of broad, shallow pits ; the femora and tibiae ciliated with long 

 ferruginous bristles. Venter obesely convex, polished, invested with 

 long ferruginous hairs ; the sides deeply, finely, and behind more closely, 

 punctate ; sides of the segments exteriorly with a line of coarse punc- 

 tures ; the middle broadly impunctate ; connexivum roughly i)unctate ; 

 the edge posteriorly faintly waved. $. 9. 



Length, 5J to 6^ millimeters. Breadth of pronotum, 3 to 3J millimeters. 



Inhabits California (Dr. G. Horn); San Francisco (James Behrens). 



Amnestus, Dallas. 

 A . pusillus. Kew sp. 



General form of A. spinifrons, Say ; very i^ale ferruginous, polished. 

 Pronotum a little narrower anteriorly; the lateral margin anteriorly 

 abruptly rounded ; transverse line deeply impressed ; the surface coarsely 

 punctured; the humeri and posterior margin more finely punctured j 

 the lateral submargin more broadly depressed posteriorly. Scutellum 

 small, triangular, pointed, rufo-piceous, closely punctured. Legs flavo- 

 testaceous or pale ferruginous ; the anterior femora unarmed, ciliated ; 

 the anterior tibiie compressed, with the spines rather long and slender. 

 Corium paler than the pronotum, coarsely, closely punctate ; the disk 

 more remotely so ; posterior margin deeply sinuated ; membrane trans- 

 parent, faintly whitish, much shorter than the corium. Venter with 

 prostrate pubescence, minutely rugulose, moderately convex. 



Length, 2 to 2^ millimeters. Width of pronotum, 1 to 1^ millimeters. 



Inhabits Indian Territory, Texas, Cuba, and generally the Eastern 

 United States south of Cape Cod. It lacks the femoral tooth, which is 

 so conspicuous in A. spinifrons. 



Macroporus, Uhler. 



Broad-oval, feebly convex ; the sides of the head and pronotum spar- 

 ingly ciliated. Head broad, clypeate ; the margins broadly reflexed, 

 armed with short spines ; tylus flattened, a little narrowed at tip, the 

 recurved margin crossing its tip; bucculse almost percurrent, not widened 

 at tip; rostrum reaching between the intermediate coxa*; the basal 

 joint a little shorter than the bucculre, the second rather shorter than the 

 third and fourth united; these latter subequal. Antennae moniliform 

 toward the apex ; the basal and second joints slender, cylindrical ; the 

 second scarcely half as long as the third ; the third, fourth, and fifth 

 subequal, stouter ; the fifth acute at tip. IPronotum transverse, quad-
