TRIBE III. — CORISCINI. 267 



196 (327). CORISCUS pilosulus (Herrich-Schaeffer), 1848, 101. 



Elongate, slender, depressed above, subconvex beneath. Color above 

 variable, usually grayish-yellow, the head fuscous, with tylus and a line 

 each side dull yellow, a narrow stripe below eye and the edge of side 

 margins of pronotum whitish; apical third of pronotum, tips of joints 

 1 — 3 of antenna?, tips of tibiae and tarsi fuscous or piceous-black; ter- 

 minal joint of antenna? dusky; connexivum as in eurinus; membrane pale 

 brown. Under surface and apical half or all of femora black with a 

 brownish lustre, thickly clothed with appressed whitish pubescence. An- 

 tenna? with basal joint a little longer and more slender than in eurinus, 

 but slightly shorter than second, third one-fourth shorter than second, 

 fourth stouter, not as long as second and third united. Pronotum longer 

 than wide, the sides straight and converging, the apex about two-thirds 

 the width of base ; humeri prominent, acute, slightly projecting upward ; 

 disk finely, evenly, not closely punctate; hind margin subtruncate, sinuate 

 on sides. Elytra finely and sparsely punctate. Length, 10 — 14 mm.; 

 width, 2 — 2.7 mm. 



Common in the southern half of Indiana, less so in the north- 

 ern counties, July 12 — Oct. 15. Occurs with eurinus on various 

 flowers and foliage, especially those growing in sandy soil. 

 On Sept. 10 and again on Oct. 15 scores were once found 

 mating on the ground along the sandy bottom of the bed of 

 the old Wabash and Erie Canal in Vigo County. The bouncing 

 bet or soapwort, Saponaria officinalis L., grew in abundance along 

 the banks of the canal and in summer the bug was plentiful on 

 its foliage. Along a pathway on the sides of the high wooded 

 knobs near New Albany it was also common and mating on 

 Oct. 9. 



Ormond, Sanford and Dunedin, Fla., Oct. 25 — April 4. Fre- 

 quent on weeds and grasses along the sandy margins of ponds. 

 Van Duzee found it "common and widely distributed in Flori- 

 da," and Barber records it from numerous stations. Its general 

 range is more southern than that of eurinus, extending from 

 New England west to Wisconsin and Nebraska and south and 

 southwest to Florida, Texas and California. One of the Dun- 

 edin specimens taken in December is almost wholly fuscous- 

 black above with membrane deep black, while the general hue 

 of another is brick-red, the membrane almost white. It is a 

 more slender species than eurinus and easily distinguished by 

 the prominent acute humeri and white edges of pronotum.
