FAMILY L1I. CERAMBYCID/E. 



basal half often black; disk sparsely and rather finely punctate. Elytra 

 more coarsely and closely punctate, the tips rounded or feebly subtruncate. 

 Length 11-16 mm. 



Throughout the State ; scarce. May 24-June 23. Breeds in the 

 living twigs of cottonwood, Populus monilifera Ait. A number of 

 the specimens in the collection were taken from sidewalks in Terre 

 Haute and Indianapolis. 



2012 (6496). Oberea bimaculata Oliv., Ent, IV, 1795, 21. 



Elongate, slender, cylindrical. Black, shining; thorax 

 yellow, with two round black spots on disk and often with 

 a small black one in front of scutellum ; the lower portion 

 of sides also black. Thorax and elytra punctured as in 

 ocellata. Length 8-12 mm. (Eig. 475.) 



size. (After Forbes.) Throughout the State, frequent; more so m the 

 northern counties. June 4-June 26. Often taken by sweeping low 

 herbage along the borders of marshes. Breeds in the canes of rasp- 

 berries and blackberry. In var. lasalis Lee. the thorax has two dis- 

 cal spots and the entire basal margin black. 



2013 (6503). Oberea teipunctata Swed., Ac. Nya Handl., 1787, 197. 

 Elongate, slender, cylindrical. Color exceedingly variable. In typical 



tripunctata the body beneath is usually in great part yellow, sometimes 

 wholly black ; head fuscous, rarely yellow ; thorax yellow, with two spots 

 on disk and another in front of scutellum black ; elytra each with a wide 

 discal stripe dull yellow, the suture and margins blackish. Thorax sparsely 

 and rather shallowly punctured. Elytra coarsely, densely and deeply punc- 

 tured, the punctures in rows. Length S-16 mm. 



Throughout the State ; frequent. May 24-June 24. Breeds in 

 the twigs of cottonwood ; also in those of blackberry. 



A number of color varieties of this and bimaculata have been 

 named, and the two species probably merge. Among the varieties 

 are myops Hald., having the head yellow, the sutural black stripe of 

 elytra and black spot before scutellum of thorax wanting, and fla- 

 vipes Hald., black, with legs yellow and thorax almost wholly black. 



2014 (6501). Oberea ocellata Hald., Trans. Amer. Ent. Soc, X, 1847, 56. 

 Elongate, subcylindrical. Under surface and femora entirely red ; head 



and thorax usually red, rarely more or less black, the latter with two small, 

 black, rounded spots on disk ; elytra, and usually the tibise and tarsi, black. 

 Head and thorax rather sparsely, deeply and coarsely punctate, the latter 

 somewhat constricted at base. Elytra with rows of coarse punctures which 

 are less dense than in allied species. Length 13-14 mm. 



Lake and Lawrence counties ; rare. June 9-July 4. Probably 

 breeds in blackberry stems, as the two specimens at hand were taken 

 by sweeping about a cluster of these bushes.
