extremely feebly sinuate in circular arc, the apical angles right, not rounded ; 

 base transverse, broadly, feebly bisinuate, the basal angles slightly obtuse, not 

 at all rounded ; sides rather strongly arcuate, straight and feebly convergent 

 in basal half; disk wider at the middle than at base, finely, sparsely punctate 

 in the middle for a space equal to one-half the total width, then abruptly very 

 deeply, longitudinally rugulose thence to the sides, the latter margined with 

 a very fine cariniform bead. Scutellum minute, transverse. Elytra about 

 three and one-half times longer than the prothorax and very slightly wider, 

 the two bases equal in width ; apex ogival ; disk with unimpressed rows of 

 shallow, rounded approximate punctures, generally moderate in size but be- 

 coming rapidly coarse toward base and especially near the humeri, the series 

 extending to the apex ; intervals flat, each with a single quite regular line of 

 very fine feeble punctures, those of the sutural interval generally more irregu- 

 larly disposed. Abdomen very finely, feebly and sparsely punctate. Legs 

 slender, the posterior tarsi but just visibly shorter than the tibiae. Length 

 5.5-6.7 mm. ; widtli 2.3-2.7 umi. 



California (Los Angeles, Pomona and San Diego) ; Arizona. 



The metasternum is scarcely perceptibly longer than the first 

 ventral segment, and is feebly, very sparsel}- but rather coarsely 

 punctate, the episternum similarly punctate. The transverse meta- 

 sternal groove is strongly impressed. 



A very common species, readily known by its slender parallel and 

 rather convex form, very shining surface, and evenly and abruptly 

 rugulose lateral portions of the pronotal disk. The hind wings are 

 very well developed, being rather longer than the elytra. 



E. angustus n. sp. — Very elongate-oval, moderately convex, very pale 

 castaneous, strongly shining but not polished, the elytra distinctly alutaceons 

 toward apex ; elytral setse very small but projecting distinctly beyond the 

 confines of the punctures. Head nearly one-half wider than long, the punc- 

 tures moderately fine and dense, the epistonia very broad, the apex truncate 

 or extremely feebly sinuate; eyes large, the ridges fine but strong, advancing 

 distinctly beyond the eye ; antennae slender. Prothorax scarcely three-fifths 

 wider than long, the apex much narrower than the base, very feebly sinuate 

 in circular arc ; apical angles right, not at all rounded ; the basal slightly 

 obtuse, scarcely at all rounded; base transverse, broadly, feebly bisinuate; 

 sides evenly convergent fiom base to apex, rather feebly and very evenly 

 arcuate throughout ; disk widest very near the base, finely, sparsely punctate, 

 the punctures becoming rather al)ruptly much larger, coarse but shallow, 

 extremely dense and partially coalescent in lateral fourth. Elytra nearly 

 three and one-half times as long as the prothorax and, near the middle, very 

 distinctly wider, the two bases equal in width ; sides evenly, distinctly but 

 feebly arcuate; apex ogival; disk with distant unimpressed rows of small 

 shallow approximate punctures, which become but very slightly more distinct 

 toward the humeri, the series becoming rather confused toward the apex ;
