GEOLOGICAL SURVEY OF THE TERRITORIES. 403 



DasycoriSj Dallas. 



D. huinilis. New species. — Closely resembliag D. pilicornis, Burm., of 

 Europe; but ratber more slender; tbe bead longer and the antennae 

 more slender. Fusco-cinereous, or pale fulvo-griseous, bispid; tbe 

 bead pale beneatb; on tbe sides is a dark-brown stripe running from tbe 

 antennse to tbe base, tylus carinately elevated. Antennae baving tbe 

 second joint distinctly sborter tban tbe tbird; the fourth i)ale fuscous, 

 conical, acuminate, not coarsely granulated and setose as tbe other joints, 

 about equal to tbe third joint in length ; antenniferous spines very short, 

 small. Eostrum reaching to the intermediate coxae; the tip piceous. 

 Pronotum remotely punctured, beset with numerous granular processes, 

 densely clothed with gray pubescence; the lateral margins, with tlioir 

 close-set, short, teeth-like i^rocesses, whitish ; humeral angles with an 

 acute, fuscous tooth, stouter and not so long as that in i). j9t?icorm&'. 

 Pectus pale clay-yellow, or even whitish, closely, coarsely punctured, 

 granulated, and with whitish, somewhat matted pubescence. Legs 

 pale clay-yellow; the femora granulated, pubescent, mottled with brown; 

 tibise darker at tip; the tarsi somewhat embrowned, and the nails piceous. 

 Mesosternum blackish. Scutellum coarsely punctured, covered with 

 dense, whitish pubescence; the tip white. ' Hemelytra beset with coarse, 

 brown granules and short, whitish pubescence; tbe embolium grooved, 

 flecked with brown; membrane pale, tbe nervures interruptedly brown. 

 Connexivum with i^ale, transverse lines, between which are fuscous 

 clouds. Venter minutely wrinkled, closely punctured ; the pubescence 

 minute, whitish ; tbe basal segments having several brown points each 

 side, and usually with a series on each side of all the segments; tbe 

 lateral margins interruptedly infuscated. 



The posterior femora usually have two spurs beneath, near the tip, and 

 two or three small teeth close to the tip. Sometimes tbe two longitu- 

 dinal nervures of the corium are interruptedly fuscous. 



Length to tip of venter, 8J-9 millimeters. Width across the humeri, 

 2-2^ millimeters. 



Specimens have been collected in Colorado, Kansas, and California. 



Harmostes, Burm. 



S. reflexulus^ Say, (Heteropt., New Harmony, \). 10, No. 1 ;) ^. costa- 

 lis, H. Schf., (Wanz. Ins., IX, p. 270, Pig. 992 ;) H. virescens^ Dallas, 

 (British Museum List, II, p. 520, No. 1.) — Brought by the survey 

 from Colorado. The dark and also the red varieties seem to find their 

 fullest coloring in the region adjacent to Maryland. The western speci- 

 mens which 1 have hitherto examined have been chiefly of tbe pale- 

 green type. 



AitfeiuSj Stal. 



A. impressicolUs, Stab, (Kongl. Svenska Akad., vol. IX, p. 222.) — It 

 inhabits Dakota, Arizona, California, and Texas. 



Corizus^ Fallen. 



1. C. horectUs, Uhler, (Proc. Acad., Pbila., 18G1, p. 284.).— This spe- 

 cies is very variable in form and marking, and it may yet prove to 

 be indentical with C. pimctiventris^ Dallas. It closely resembles C. 

 crassicornis^ Linn., of Europe. Tiius far it has occurred iu Colorado, Ne- 

 braska, Canada, and Massachusetts.
