XLVITI. SOIOCHARKLLA Casey. 3905. 



Closely related to Sciocharis, but differing by the smaller size 

 and in the characters mentioned in the generic key. One species 

 belongs to the Austroriparian fauna. 



825 ( ). SCIOCHARELLA DELicATULA Casey, Trails. Acad. Sci. St. Louis, 



XV, 1905, 159. 



Slender, parallel. Pale to dull brownish-yellow, very minutely punc- 

 tate, alutacemis; legs and antenna 1 paler. Head piceous, as long as wide, 

 widest at the truncate base; eyes situated twice their length from base. 

 Second anteniial joint as long as the next two combined and much thicker. 

 Thorax as long as wide, scarcely narrower than head, sides nearly straight, 

 angles scarcely rounded. Elytra quadrate, parallel, much wider than head, 

 a tit'th wider and one-fourth lunger than thorax. Length 1.8 mm. 



Crawford and Posey counties; rare. May 26-June 3. Described 

 from Alabama. 



XLIX. TRACHYSECTUS Casey. 1886. 



Represented east of the Rocky Mountains by one small piceous 

 species having the gular sutures narrowly separated and nearest to- 

 gether in front of middle ; neck half as wide as head ; third joint of 

 antenna distinctly longer than second, the outer joints bead-like; 

 prosternum not carinate; upper surface coarsely and densely punc- 

 tured. 



826 (2560). TRACHYSECTUS CONFLUENS Say, Trans. Amer. Phil. Soc., IV, 



1834, 450; ibid. II, 571. 



Rather stout, parallel, subconvex. Dark reddish-brown to piceous, 

 feebly shining; legs, tips of elytra and base of antenna? paler. Head wider 

 than long, as wide as elytra, its hind angles broadly rounded; densely, 

 coarsely and strigosely punctured. Thorax narrower than head, wider 

 than long; disk with fine, lengthwise wrinkles. Elytra slightly wider and 

 one-third longer than thorax, finely, rather closely and roughly punctate. 

 Abdomen at base slightly narrower than elytra, thence feebly widened to 

 near apex, finely and densely punctate. Sixth ventral of male with a small 

 median notch. Length 3.5 mm. 



Throughout the State; frequent, March 17-October 17. Oc- 

 curs beneath loose bark and dead leaves and in fungi. When un- 

 covered they run very rapidly. The elytra are not always paler at 

 tips and the thorax is often reddish on the sides. 



L. PARAMEDON Casey. 1905. (Gr., "over + provider. ") 



The principal distinguishing characters of this genus are the 

 strongly dilated front tarsi and the sexual characters of the males. 

 Its members hitherto known have all been from the Pacific or South- 

 western States.
