americanus Walter) at Lyme, Conn., June 16, 1918, by W. S. Fisher; 

 three male and six female paratypes collected on the same host at 

 Sherborn, Mass., June 12, 1915, by C. A. Frost; two male paratypes 

 collected July 9, 1915, at La Grange, 111. ; and one male paratype 

 collected at Galesburg, 111., from the Stromberg collection. 



This species is rather uniform in coloration, although the color 

 of the head and pronotum of the females varies from bronzy green to 

 bronzy cupreous. The sides of the pronotum show considerable 

 variation; in some examples they are arcuately rounded, whereas 

 in others the sides are strongly sinuate anteriorly, the depressions 

 at middle of pronotum vary in depth, and the prehumeral carinae 

 are more sharply elevated in some examples. The tarsi are more or 

 less variable in length, and the prosternal lobe is subtruncate to 

 arcuately emarginate in front. Length, 4 to 5 millimeters.

Male. — Form resembling that of otiosus, rather strongly shining, 

 and feebly flattened above ; head dark bronzy green ; pronotum bronzy 

 brown at middle, becoming greenish toward the sides; elytra black, 

 with a feeble greenish reflection; beneath black, with a greenish or 

 aeneous tinge. 



Head with the front wide, feebty convex, vaguely wider at bottom 

 than top, the lateral margins vaguely, arcuately expanded near mid- 

 dle, and without a longitudinal groove or depressions; surface 

 densely granulose, rather coarsely, densely punctate, becoming longi- 

 tudinally rugose on the occiput, and the surface anteriorly nearly 

 concealed by long, recumbent, silvery white pubescence; epistoma 

 scarcely transverse between the antennae, not elevated, and the an- 

 terior margin with a shallow, arcuate emargination at the middle; 

 antennae extending beyond middle of pronotum, serrate from the 

 fourth joint, and the outer joints slightly longer than wide; eyes 

 broadly elongate, and about equally rounded beneath and above. 



Pronotum nearly one-third wider than long, about equal in width 

 at base and apex, and widest at middle ; sides arcuately rounded from 

 apical angles to behind middle, then more strongly obliquely nar-
