468 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



very stout and short ; aspect of J. irroratus Say, but much thicker and 

 shorter. Head narrower than the pronotum, relatively to its width 

 longer, and more acutely triangular than in J. irroratus, smooth and 

 polished, the occipital margin with white, irregular patches, and each 

 side of. middle with a short, arcuated, or hooked black line ; vertex each 

 side posteriorly with a large patch of vermiculate or marbled fuscous 

 lines, sometimes coalescing, the surface behind these a little depressed ; 

 each side of apex with a paler spot of brown lines ; face irrorated and 

 marbled with dark brown, sometimes omitting the middle line of the 

 front and the disks of the cheeks ; occasionally fuscous with remote tes- 

 taceous dots ', epistoma a little wider at tip, the base and sometimes 

 each side marked with brown ; rostrum piceous at tip. Pronotum 

 broadly sublunate, much narrower anteriorly, transversely wrinkled, 

 minutely punctate in a few places ; generally with two brown, arcuated 

 spots on the middle behind the head, the remaining surface inscribed 

 with fuscous, sometimes also with ocherous in curved lines and 

 marblings or dots, either of which may be obliterated or confused ; 

 lateral margins curvedly oblique, pale, recurved; the posterior mar- 

 gin a little concave; the lateral and posterolateral angles rounded, 

 the latter very bluntly so ; the deflexed sides with a large black 

 patch above. Spipleurse and coxsb generally with more or less large 

 black patches on the disks and superiorly. Legs pale testaceous or 

 yellowish-white; the femora stout, the anterior and intermediate ones 

 twice banded or clouded and dotted with brown ; tibite, excepting 

 the posterior pair, with four black abbreviated bands, the posterior pair 

 with a large black spot at the base of each spine ; tips of all the tibiae, 

 of the tarsal joints above, and the nails and pulvilli black. Scutellum 

 short and broad, smooth, unevenly and irregularly marked and spotted 

 with fuscous. Hemelytra pale testaceous or whitish, ramosely lineated 

 with fuscous, with fuscous nervures on the clavus, the other nervure 

 pale brown, but darker posteriorly ; the inner margin of clavus broadly 

 wavedly pale, and marked with about three fuscous spots, of which 

 the posterior one is placed on the apex ; costal margin broadly curved, 

 the nervure white, just inside of it is a series of small brown spots, 

 reaching around the tip and becoming larger at that point ; transverse 

 nervules generally marked with branching brown spots ; apical areoles 

 short, with their lateral neryules curved ; the areoles are sometimes so 

 crowded with brown branching lines that the surface appears dark 

 brown, and in such specimens pale dots are conspicuous in the spaces 

 between. Wings milk-white, the nervures fuscous. Tergum black, the 

 segments sometimes margined behind narrowly and on the sides broadly 

 with testaceous, or sometimes bright yellow ; venter generally black 

 on the disk, the sides and apical segments dotted with fuscous ; gen- 

 ital segment of the female beset with remote, pale, stout bristles. 



Length to tip. of venter 5-8 millimeters: to tip of hemelytra 6-8 

 millimeters. Width of pronotum 2^-2f millimeters.
