439 



Throughout the State ; frequent. March 20-May 19. Taken by 

 sifting. Probably hibernates as imago. This, as well as the other 

 species, runs with great rapidity when disturbed. 



841 (2579). Sunics binotatus Say, Proc. Phil. Acad. Nat. Sci., Ill, 1823, 

 154 ; ibid. II, 99. 



Very slender, parallel. Head, a large spot on elytra and tip of abdo- 

 men black ; thorax, base and suture of elytra and base of abdomen reddish- 

 yellow ; antennae, legs and tip of abdomen pale yellow. Head longer than 

 wide, wider than thorax and elytra. Thorax elongate-oval, the sides feebly 

 converging from apical third to base; surface, as well as that of head and 

 elytra, punctured as in linearis. Abdomen slender, gradually broader be- 

 hind. Length 3.5-4 mm. 



Marion and Putnam counties; scarce. April 4-October 10. 

 Taken by sifting damp vegetable debris. 



S. brevipennis Austin, 3-3.7 mm. in length, occurs from Massa- 

 chusetts to Iowa and doubtless inhabits Indiana. 



*842 ( ). Sunius mscopUNCTATUs Say, Trans. Amer. Phil. Soc, IV, 



1834, 457 ; ibid. II; 572. 

 Very slender, subparallel. Pale reddish-yellow, last two abdominal 

 segments black. Head rather small, narrower than elytra. Thorax oval, 

 narrower than head, slightly longer than wide, sides rounded at apical 

 fourth, thence feebly converging to base; punctate as in linearis. Elytra 

 a third longer and distinctly wider than thorax. Abdomen at base slightly 

 narrower than elytra, its sides almost parallel. Length 3.8-4 mm. 



Throughout the State; frequent. February 20-November 28. 

 Occurs especially beneath stones, bark, etc., in high, open woodland. 

 Listed as longmsculus Mann., of which it is usually considered a 

 synonym, but Casey says the latter is a Pacific Coast species, with 

 much larger elytra. 



LVIII. Stilicopsis Sachse. 1852. (Gr., "style + face.") 



Minute pale species having the thorax almost circular, its median 

 line finely elevated; elytra short with diverging sides ; abdomen 

 broad, convex. 



843 (2582). Stilicopsis paradoxa Sachse., Stett. Ent. Zeit., 1852, 144. 



Short, parallel. Pale yellow throughout. Head scarcely as long as 

 wide, coarsely and densely punctate, its sides rounded into the slender 

 neck ; eyes prominent, coarsely granulate ; antenna? reaching middle of tho- 

 rax, the outer joints somewhat thickened. Thorax equal to head in width, 

 nearly circular, rather densely granulate-punctate. Elytra distinctly wider 

 and shorter than thorax, coarsely, closely and rugosely punctate. Abdo- 

 men at middle wider than elytra, finely, densely and roughly punctate. 

 Length 2.5-2.7 mm.
