NORTH AMEKICAN COLEOPTERA. 247 



This species is easily known by the submetallic surface lustre, and 

 is of more oblong form than any other, except parvida. It re])re- 

 sents in our fauna the intevmedia Foudras of southern Europe. 



Occurs in Oregon, California, Nevada and Arizona. 



E. parviila Fab. — Oblong ovate, moderately convex, rufotestaceous, abdo- 

 men brown, elytra often with a dark, transverse cloud at middle. Antennse pale 

 rufotestaceous, the outer four joints usually darker Head smooth, with several 

 large punctures near each eye. Thorax nearly twice as wide as long, not nar- 

 rowed in front, sides arcuate, feebly obliquely truncate at the front angles, disc 

 convex, the punctures moderate, rather closely placed, but not dense, the inter- 

 vals shiniug. ante-basal groove almost entirely obliterated. Elytra very little 

 wider than the thorax, humeri rounded, umUone feeble, strire feebly impressed 

 on the disc, a little deeper at the sides, the ])uuctures moderate and not crowded 

 on tlie disc, closer and deeper at the sides, the inner intervals a little wider than 

 tlie stria? and flat those at the sides narrow and slightly convex, all with a row 

 of tiner punctures. Prosternum coarsely, but not closely [)unctate. Metasternum 

 and abdomen brown, the latter sparsely punctate and feebly pubescent. Legs 

 pale rufotestaceous. Length .06 — .08 inch.: 1.5 — 2 mm. 



Very many of the specimens are entirely rufotestaceous above, 

 but others have an indistinct transverse cloud at the middle of the 

 elytra. In one specimen before me this forms a well marked band, 

 which does not reach the suture, the latter nai'rowly bordered with 

 brown. The legs are unitormly rufotestaceous. 



Occurs tliroughout the entire United States, extending also to the 

 West India islands. 



ORTHALTICA Crotch.

 others dis.-<imilar in the sexes, terminal joint acute at tip. Thorax 

 l)r()ader than long, scarcely wider at base, apex truncate, base ar- 

 cuate, sides arcuate, the margin not thickened in front, disc convex, a 

 moderately deep ante-basal imj^ressed line not limited externally by 

 a longitudinal impression, the ends gradually approaching the base. 

 Prosternum moderately separating the coxa?, dilated behind them, 

 and with the ei)imera closing the coxal cavities behind. Mesoster- 

 num not wide, nearly horizontal. First ventral segment as long as 

 the next three, these gradually decreasing in length, fifth longer than
