*2212 (7022). riiYLLOTRETA siNUATA Stepli., Illust. Brit. Entom., IV, 297. 



Elongate-oval, subconvex. Piceous, shining; elytra each with a nar- 

 row, dull yellow stripe, parallel with the suture at base, and with a short, 

 broad branch behind the humerus, the apical third strongly sinuate; an- 

 tenna^ piceous, the three or four basal joints paler. Thorax nearly twice 

 as wide at base as long, distinctly narrowed in fr<mt; disk convex, surface 

 finely alutaceous, rather coarsely and sparsely punctate. Elytra slightly 

 wider than thorax, with the punctures coarser and more close-set than on 

 the latter. Length 2.5 mm. (Fig. 526, c.) 



Throughout the State; common. March 19-November 1. Prob- 

 abh^ hibernates. Taken by sifting in early spring and late autumn 

 and by beating hickory and sweeping grass in siunmer. 



2213 (7023). PiiYLLOTRETA viTTATA Fabr., Syst. Eleut., I, 1801, 469. 

 Smaller than sinuata and with the yellow stripe of elytra narrow at 



middle, incurved at base, broader and slightly incurved at tip ; legs piceous, 

 tibite and tarsi brownish-yellow. In the males the fourth joint of antennae 

 is broader than the third, fifth a little broader and nearly equal in length 

 to third, whereas in sinuata the fourth is much broader than the third, and 

 the fifth longer than the two preceding together and much dilated. Length 

 2 mm. (Fig. 526, d.) 



Throughout the State ; frequent. I\ray 12-September 25. Taken 

 by sifting and sweeping. Occurs on cabbage and other cruciferous

 grass, etc. 



2214 (7031). Phylloteeta robusta Lee, Proc. Amer. Phil. Soc, 1878, 614. 

 Oblong-oval, similar in form and size to vittata. Piceous, shining; ely- 

 tra each with a broad yellowish stripe parallel with the suture for most of 

 its length, dilated at base to form a broad process behind humerus and in- 

 curved tow-ards scutellum, the apical third broadly expanded. Thorax nearly 

 twice as wide as long, coarsely, deeply and closely punctate. Elytra slightly 

 wider and more coarsely punctured at base than thorax, more finely punc- 

 tured towards apex. Fourth and fifth antennal joints of male much broader 

 than third, the fifth as long as the two precedi. g. its apical free angle pro- 

 longed. Length 2 mm. (Fig. 52H, f.)
