1184 FAMILY On. CHRYSOMEODiE. 



with humeri rounded, margins narrowly flattened, surface coarsely and 

 closely punctate. Length 4^.5 mm. (Fig. 51S, d.) 



Southern half of State ; frequent, April 11- June 14. Taken by 

 sweeping and beating low shrubs along roadsides. The black discal 

 space of elytra is sometimes so narrow as to occupy but half the 

 space between the suture and margin. More often it is so broad as 

 to leave only a pale margin and the species then resembles closely 

 0. quercata. The more oval form, indistinct umbone and paler 

 under surface will serve to distinguish it from the latter.

Broadly oval, subdepressed. Dull brownish-yellow ; elytra each with 

 four narrow fuscous or piceous lines or stripes as follows : one sutural. not 

 reaching base, a second each side Of scutellum. extending nearly to middle : 

 a third slightly oblique, extending from umbone two-thirds to apex, and 

 a fourth short one reaching from the umbone parallel with the side mar- 

 gin ; these stripes may be one or all absent, or rarely all confluent into a 

 large discal piceous space ; head pale, sparsely punctate. Antenme longer 

 than half the body, fuscous, the basal joints paler, third and fourth equal. 

 Thorax nearly three times as wide as long, margins broadly flattened, front 

 angles not dentiform, surface alutaceous. sparsely and obsoletely punctate. 

 Elytra broadly oval, umbone moderately prominent ; surface rather coarsely 

 and closely punctate. Length 3.5-5 mm. (Fig. 518, c.) 



Throughout the State, frequent ; much more so in the northern 

 counties. May 12-July 11. Taken by sweeping 

 and beating foliage, especially that of oak. Listed 

 by Henshaw as a variety of quercata, but distinct.
