r,4:; 



1034 (3204a). Languria trifasciata Say, Journ. Phil. Acad. Nat. Sci., 



Ill, 1823, 462; ibid. I, 86. 

 Elongate; the elytra tapering to an obtuse point. Head, basal and 

 apical thirds of elytra bluish-black ; thorax, a broad median band of elytra 

 and joints two to six inclusive of antennae, reddish-yellow ; beneath as in 

 angustata. Length 6-7.5 mm. 



Throughout the State; frequent. March 16-May 29. Usually 

 regarded as a variety of angustata. but in my opinion specifically 

 distinct. Occurs especially on the foliage of the wild lettuce, Lac- 

 tuca canadensis L.. but often found on flowers of buttercup (Ra- 

 nunculus) . 



1035 (3207). Languria lecontei Crotch, Trans. Amer. Ent. Soc, IV, 1873, 



351. 



Elongate, parallel. Nearly uniform greenish-black; Hi >rax reddish-yel- 

 low with a large greenish-black spot on center of disk. Head and thorax 

 sparsely but distinctly punctate. Elytra 1 punctures in rows, with a few 

 finer ones on intervals. Length 10.5 mm. 



Vigo County ■ rare. March 12. Described from Illinois. 



1036 (3209). Languria gracilis Newm., Ent. Mag., V, 1838. 



390.- 



Resembles lecontei, but more narrow. Head, at least 

 in part, red ; greenish-black mark on thorax extended into a 

 stripe reaching from base to apex. Varies with the thorax 

 entirely greenish-black. Length 8.7-10 mm. (Fig. 203.) 



Southern half of State; frequent. May 21-October 

 28. Occurs on ragweed (Ambrosia), fleabane (Eri- 

 geron) and other low herbs from which it is taken by 

 sweeping.
