2365 ( 7609). Isomiea quadeisteiata Coup., Can. Naturalist, 1865, 62. 



Rather broadly oval, convex, feebly shining. 

 Dark reddish-brown to piceous. the head and 

 thorax sometimes almost black; antennae and' 

 tibiie usually paler, the former one-half the 

 length of body. Thorax nearly twice as wide 

 as long, sides rounded on basal half, converging 

 toward apex, which is two-thirds as wide as 

 base; disk finely and densely punctate. Elytra 

 at middle one-fourth wider than thorax ; surface 

 finely and sparsely but distinctly punctate, each 

 with two striae plainly visible only on apical half 

 near the suture. Length 5-6.5 mm. (Fig. 567.) 



Throughout the State ; much more com- 

 mon in the northern counties, where it 

 occurs aboundantly on huckleberry and other shrubs along the 

 borders of marshes. May 11- August 15. The last joint of the max- 

 illary palpi is much more broadly triangular than in sericea. 



2366 ( ). Isomiea similis sp. nov. 



Elongate-oval, convex. Dark reddish-brown, feebly shining; antennie 

 and legs paler ; pubescence fine, short, yellowish, rather dense. Head small, 

 less than half the width of thorax, finely and densely punctate. Antenna! 

 slender, one-half the length of body; second joint one-fourth the length of 

 third, the latter a little longer than fourth. Thorax twice as wide as long, 

 strongly narrowed from base to apex; sides evenly rounded, base bisinuate. 

 hind angles rectangular ; surface finely and densely punctate and with a 

 fine impressed median line on basal third. Elytra at base but slightly 

 wider than thorax ; surface finely and rather sparsely punctate, the sutural 

 stria? extending three-fourths to base, the others evident only near apex. 

 Prosternum densely and roughly punctate ; abdomen finely and rather close- 

 ly punctate. Length 7 mm. 



Posey County; rare. July 9. The larger size and much larger 

 eyes easily distinguish it from 4-striata. 



2367 (10,693). Isomiea oblonoula Casey, Ann. N. Y. Acad. ScL, YI 1891 

 151. 



Elongate-oblong, subparallel. Uniform dark reddish-brown to piceous, 

 clothed with short, dense, pale pubescence. Thorax three-fourths wider 

 than long, sides nearly straight except on apical fourth, where they are 

 rounded into the apex, hind angles obtuse ; surface finely and very densely 

 punctate, with a wide but feeble impression each side near base. Elytra 

 four times as long as thorax ; disk finely and densely punctate and with dis- 

 tinct but slightly impressed stria?, without rows of punctures. Length 6 7- 

 7.2 mm. 



Starke, Tippecanoe and Orange counties; scarce. June 1-June 

 21. Beaten from oak.
