1092 FAMILY l.n. — CEEAMBYCID.-E. 



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

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

 Length 11-16 mm. 



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

 living twigs of Cottonwood, Popnlus monilifera Ait. A number of 

 the specimens in the collection were taken from sidewalks in Terre 

 Haute and Indianapolis. 



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

 Elongate, slender, cylindrical. Black, shining; thorax 



yellow, with two rpund 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 

 Fig. 477 Natural ocellata. Length 8-12 mm. (Fig. 475.) 

 size. (After Forbes.) Throughout the State, frequent; more so in 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. basalis Lee. the thorax has two dis- 

 cal spots and the entire basal margin black. 



2013 (6503). Obebea tripunctata Swed., Ac. Nya Handl., 1787, 197. 

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



tripwnotata 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 himaculata have been 

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

 are niyops 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). Obebea ocellata Hald., Trans. Amer. Ent. Soc, X, 1S47, 56. 

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



and thorax usually red, rarely mere or less black, tlie latter with two small, 

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

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

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

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



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

 breeds in blackl)erry stenis, as the two specimens at hand were taken 

 by swee]ung about a cluster of these bushes.
