coxae; mesosternal sulcus deep, the tuberculate sides rough; osteolar canal 

 broad and angled, the apex shorter than in allied species. Anterior femora 

 shallovvly sulcate beneath, the anterior edge with one large tooth and about 

 five small ones either side, the basal larger; hind tibiae with irregular long 

 hairs along its inner face, the outer surface nearly smooth. 



Color, black, dull on the scutellum but more or less polished elsewhere; tip 

 of tylus, basal segment of antennas, rostrum and legs honey-yellow; segments 

 II to IV of antennae and anterior femora darker or piceous; collum and 

 posterior lobe of pronotum castaneous, the latter with humeral angles and two 

 oblique discal rays blackish; expanded pronotal margins whitish edged with 

 fuscous; elytra testaceous to tip of scutellum, then abruptly fuscous-brown 

 veined with castaneous; membrane brown with base and veins pale, both 

 outer and inner angles with a large oval white spot; hind margin of meta- 

 pleurae, acetabulae and genital segment castaneous. 



Described from one male taken by me at Sunset, Colorado, 

 July 19, 1903, at an elevation of 8,000 feet. This species 

 has a longer, more pointed and flatter scutellum than ob- 

 scurus and the hind tibiae are ciliate within but bare in ob- 

 scurus where also the pale basal portion of the elytra is 

 shorter and does not include the clavus as it does in dimi- 

 datus. E. ferns has the anterior lobe of the pronotum flatter 

 and opaque, the hind tibiae entirely ciliate and the scutellum 

 shorter. 



Holotype, male, in collection of the author. 



Type locality, Sunset, Colorado. 



8. Eremocoris opacus, new species 

 Shorter, broader and more opaque than in any of our 

 other species. Length 6 mm. 



Head a fourth broader across the eyes than long, shagreened but scarcely 

 punctate, opaque at base, somewhat polished and clothed with appressed 

 golden pubescence anterior to middle line of eyes. Basal segment of antennae 

 surpassing clypeus by a little more than half its length, segment II one-half 

 longer than I; III and IV subequal, a little shorter than II. Pronotum 

 almost a third wider than long, regularly narrowed anteriorly much as in 

 ferus, moderately constricted at basal third, anterior lobe flattened as in jerus, 

 nearly impunctate, dull black; collum narrow and distinct; expanded margins 

 a little broader than in obscurus, armed by a single row of distant long 

 hairs; posterior lobe coarsely punctured, hind edge less deeply excavated. 

 Elytra more opaque than in obscurus, the expanded costa only a little polished; 

 membrane complete, attaining apex of abdomen ; scutellum a fourth broader 

 than long; anterior femora of male about as in obscurus, armed with two 

 strong teeth, the apical the larger, and about three small ones either side 

 the apical large tooth; anterior tibiae much curved and expanded at apex 

 where there are two larger teeth and about four smaller ones placed basally 

 from these; rostrum attaining middle of hind coxae; segment I passing base 

 of head, II subequal to III and IV together; mesosternal sulcus shallow, its 

 sides scarcely tumid; osteolar canal right-angled; male genital segment 

 feebly bi-tuberculate with a broad shallow apical sulcus. 



Color, dull black becoming piceous or castaneous and polished on the an-
