TRIP,!-: III. HYPERIXI. 173 



clian carina more distinct; finely rugose-striate, both it and head sparsely 

 covered with yellowish scale-like hairs. Thorax subcylindrical, slightly 

 wider than long, sides feebly rounded, ocular lobes small; disc with punc- 

 tures concealed by small convex scales, giving it a granular appearance, 

 a more or less ill defined impression along the median line. Elytra at 

 base one-fourth wider than thorax, humeri rounded, prominent, base 

 slightly emarginate, sides subparallel for three-fifths their length, then 

 gradually narrowed and compressed to apex; striae fine, punctures rather 

 large; intervals slightly convex, the alternate ones more elevated and 

 bearing a row of rather long, slender seta?; the others more or less setose 

 on declivity. Abdomen glabrous, densely punctate. Last ventral of female 

 with a large transverse fovea. Length 4 5 mm. 



Frequent throughout Indiana, mil eh more so in the southern 

 portion ; March IT June 2. Evidently hibernates as taken by 

 sifting and beneath bark in early spring; later by sweeping road- 

 side herbage. Ranges from New England and Canada to Mis- 

 souri. We have included Avitli xjHirxiis a number of southern In- 

 diana specimens identified by Liebeck some years ago as loiif/nlus 

 Dietz. They differ only in being smaller, more narrow and par- 

 allel, in having the elytra partially or wholly denuded of scales 

 and in the thorax being slightly more rounded and devoid of 

 median impression. Listrortcrcs Hncatulus Say (1831, 11) is said 

 by Dietz to be only a form "densely covered with grayish scales, 

 completely concealing the punctures and with the thoracic fur- 

 rows more distinct."

Oblong. Black, densely clothed with fuscous and grayish-white 

 scales, the latter forming a narrow median line and a broad stripe each 

 side on thorax, covering the scutellum and humeri and forming a few ir- 

 regular spots on the disc of elytra; antennae, tibiae and tarsi dark reddish- 

 brown. Beak as in sparsus, its lateral carinae more distinct than there. 

 Thorax as in key, finely and densely granulate-punctate. Elytra one-third 

 wider than thorax, strongly emarginate at base; sides very feebly con- 

 verging for three-fourths their length, then rapidly rounded to apex; 

 striae broad, feebly compressed, their punctures large, subquadrate, close- 

 set; intervals slightly convex, alternate ones more elevated near base, each 

 with a row of slender seta?. Under surface coarsely punctate; front tarsi 

 less dilated than in others of the group. Last ventral of female deeply 

 and sharply foveate, emarginate. Length 3.5 4 mm. (Fig. 62, /. ) 



Lawrence County, Indiana, rare; July 29. Taken by sweeping. 

 Irvington, New Jersey, June 10. Ranges from New York to Ne- 

 braska and Colorado, south to Texas.
