beneath very coarsely transversely strigose, and with sparse short pubes- 

 cence. Abdomen very sparsely punctate, and slightly pubescent at the 

 sides. Mesosternal umbone moderately prominent, rounded at tip. 

 Length .52-. 74 inch ; 13-19 mm. PI. iv, fig. 16. 



The club of the male antenna is a little longer than that 

 of the female ; anterior tibise tridentate in both sexes. 



The specimens before me, six in number, are exactly alike 

 in their elytral markings, scarcely varying in the minutest 

 detail ; in one in my cabinet, from Utah, the thorax has the 

 large black discal space replaced by four smaller spots. 



The entirely glabrous surface and the general outline of 

 this species place it in close alliance with, fulgida. 



Occurs in the Peninsula of California, and extends to 

 South-western Utah at St. George (Dr. Palmer). 



E. fulgida Fab. 



This species, well known fromits brilliant green surface, varying to blue, 

 needs but little comment. The upper surface is entirely devoid of pubes- 

 cence. The head is brilliant green, the thorax similar in color, but mar- 

 gined at the sides with yellow, its surface sparsely punctate. On the ely- 

 tra the traces of costse are almost entirely obliterated, the punctuation 

 usually sparse and indistinct, often more or less maculate, with cretaceous 

 spots. The pygidium is concentrically strigose, and with four cretaceous 

 spots more or less confluent. The metasterum is smooth at middle, and at 

 sides deeply strigose. The abdomen is smooth, with but few coarse punc- 

 tures at the sides, and along the margin of the segments, the sides are 

 usually broadly cretaceous, sometimes with a double row of cretaceous 

 spots. The mesosternal umbone is prominent, oval at tip. The legs are 

 reddish or brownish-yellow, tarsi piceous. Length .52-.80 inch ; 13-20 mm. 



The male has a larger antennal club than the female, the 

 tibiae are tridentate in both. 



In the specimens from the Northern States, the elytra have 

 less of the greenish surface lustre, and exhibit a brownish- 

 red ground color ; these have also the fewest whitish spots. 

 In the specimens from the Gulf States, the color is always 

 more brilliant, the punctuation more evident, and the whit- 

 ish spots more numerous. 



Occurs from the Middle States westward to Missouri, and 

 south to Florida and Texas. 



E. californica Lee. 



Bright green, opaque above, shining beneath, very similar to fulgida, 

 upper surface without pubescence. Clypeus longer than wide, slightly
