AMERICAN HEMIPTERA. 21 



a short grey pubescence; color soiled yellowish or tawny, paler than in Balli. 

 marked above with a longitudinal pale median line, which becomes almost obso- 

 lete on the pronotum. Narrow lateral and posterior margin of the pronotiini and 

 the region of the callousities sometimes l)lackish. Impressed subn)argins and a 

 few ol)solete markings on the disk of the pronotum brown. Scutellum in the 

 female with an oval subbasal black spot, and on each side of this an indefinite 

 longitudinal vitta that is deflected to the lateral maigins behind the middle and 

 the apical region brownish, bordered incompletely with black. In this dusky 

 apical field is a pale spot defined anteriorly by a black semicircle, and there are 

 groups of dusky punctures near the basal angles and on either side of the pale 

 median line behind the black subbasal spot. In the male all these dark mark- 

 ings become nearly obsolete but the pale median line and the black apical semi- 

 circle persist. Beneath black with the antennae, base of the rostrum, coxae and 

 venter pale. Legs piceous, with the knees, exterior surface of tibiae, and base of 

 the tarsi pale. Connexivum alternated with brown. In the female the ventral 

 sutures and a line on the stigmata are blackish. In both sexes the whole lower 

 surface is densely white pubescent. Length 5 nnn. 



Described froiu a pair taken at Holly, Colo., September 8, 1898, 

 and sent to nie by Prof. Ball with the preceding species, and three 

 t'euiales taken at Fort Collins, Colo., in June, and kindly sent to 

 nie l)y Prof. C. P. Gillette. This species might be placed in (Jruidrus 

 were it not for the absence of an osteolar orifice and the form of the 

 pronotum. The hairy vestiture of the whole surface is also charac- 

 teristic of Odoiitoscelis. 



Subfamily Graphosomid^e. 

 This subfamily is represented in our fauna by but two genera. 

 These are black and rough-looking little insects, with the scutellum 

 large, covering nearly the whole upper surface of the abdomen and 

 furnished with a very short frenum. They have the humeral angles 

 of the pronotum eraarginate, with a tooth before the sinus; the an- 

 terior angles of the pronotum are armed with a tooth or lobe, and 

 the head is long with the sides sinuated, the eye prominent and 

 stylated, and the cheeks broad at apex, equalling or exceeding the 

 tylus. They may be distinguished as follows : 



Cheeks thin, flattened, a little longer than the tylus; antenniferous tubercules 

 prominent beyond the sides of the head, armed without with a curved 

 spine; angles of the pronotum armed with a short acute tooth. 



Genus Podops. 



Cheeks convex, tumid, considerably longer than, and contiguous before, the tylus; 

 antenniferous tubercles scarcely prominent beyond thesidesof the head, 

 unarmed ; anterior angles of the pronotum armed with a prominent 

 rounded and denticulate lobe Genus Oucozygia.
