A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI

punctured, more densely at sides. Elytra a little wider than the thorax, parallel, 

 narrowing to apex at apical third, margin feebly serrulate, apices obtuse ; disk 

 very slightly depressed, costae obliterated in front, faintly indicated behind, 

 basal foveae faintly indicated, between the first and second costae at middle a 

 faint longitudinal impression, surface uneven, finely rugose, punctation finer than 

 that of thorax, becoming obsolete toward apex. Body beneath transversely con- 

 fluently punctured, last segment with a feeble serrulate margin, prosternum 

 lobed in front ; anterior femur with a moderately large tooth, serrulate 

 externally. 



"Tulare Co., California, one male in collection of Dietz. 



"Male. — Prosternum distinctly depressed at middle, densely punctate, sparsely 

 pubescent, anterior tibiae nearly straight, with a very feeble dilation at tip; 

 middle tibiae nearly straight, dilated at tip, posterior tibiae straight; last 

 ventral segment semicircularly emarginate; last dorsal truncate at tip, some- 

 what coarsely punctate. 



"Length 7 mm. 



"Although a little more depressed than cyanella Horn it is best placed near 

 that species from which it differs by the opaque surface, the entirely different 

 surface sculpture and the two irregular elongate purple spots at apex of elytra, 

 which are perhaps as variable as in lucona and purpureoplagiata." 



The above is a copy of the original description. Schaeffer's origi- 

 nal spelling is subapaca, which is presumably a typographical error 

 for subopaca, as he probably intended so naming the species because 

 the dorsal surface of the body is subopaque. This species was de- 

 scribed from a single male in the Dietz collection, but this type can- 

 not be located, and no specimens which could be identified as this 

 species have been seen by the writer.
