hh. Surface moderately shining, very indistinctly punctate; each elytron 

 with an oblique yellow band at middle, not reaching the suture, 

 and an oval apical spot. 1368. obliquatulus, 



1361 (4154). Hypnoidus steiatulus Lee, Trans. Amer. Phil. Soc, X, 



1853, 488. 



Oblong, subdepressed. Piceous black, opaque, finely pubescent with 

 yellowish hairs ; legs pale, the femora darker. Head densely rugosely punc- 

 tate. Thorax slightly wider than long, narrowed in front, sides curved, 

 slightly sinuate in front of hind angles, which are stout and with a short 

 carina; disk feebly convex, densely and finely punctate. Elytra as wide 

 as thorax; sides nearly parallel to apical third, thence curved to apex; 

 disk rather flat, striate, strise punctate; intervals feebly convex, densely 

 and finely punctate. Length 3-4 mm. 



Marion and Franklin counties; rare. June 11— June 20. De- 

 scribed from Lake Superior region and probably occurs sparingly 

 throughout the State. 



1362 (4157). Hypxoidus choeis Say, Trans. Amer. Ent. Soc, VI, 1836, 

 172 ; ibid. II, 608. 



Elongate-oblong, subconvex. Black, opaque, sparsely 

 clothed with yellow hairs; elytra dull yellow with a black 

 spot each side of scutellum, and two black crossbars, 

 often interrupted on suture and with very sinuous edges ; 

 one median, the other subapical, these connected on sides 

 with a marginal line extending nearly from base to apex. 

 Thorax slightly longer than wide, sides feebly curved, 

 narrowed in front, nearly straight on basal half; hind 

 angles divergent, the carina long, extending three-fourths 

 to apex ; disk convex, coarsely and closely rugose. Elytra 

 widest in front of middle, thence gradually narrowed to 

 apex : disk deeply striate, striae punctured ; intervals con- 

 vex, roughly and sparsely punctate. Length 3.5-5 mm. 

 (Fig. 278.) 



Throughout the State; frequent, May 25-June 28. Occurs 

 especially in sandy localities near ponds and streams; also beaten 

 from flowers of swamp huckleberry. 



1363 (10,051). Hypxoidus exiguus Rand., Bost. Journ. Nat. Hist, II, 



1838, 35. 



Oblong, subconvex. Black, subopaque; elytra each with two dull yel- 

 low spots, one subhumeral, oblique-oblong, the other subapical, rounded. 

 Thorax slightly longer than wide, narrowed on apical third; sides on basal 

 two-thirds parallel, hind angles slightly divergent, the carina extending 

 three-fourths to apex ; disk densely covered with oblong granules. Elytra 

 widest slightly behind the middle, thence feebly narrowed to apex, which 

 is broadly rounded; disk rather deeply striate, the striae very indistinctly 

 punctate; intervals convex their entire length, sparsely and roughly punc- 

 tate. Length 2.5-3.5 mm.
