Variations. — This species is more or less variable in coloration. 

 In the males the front of the head varies from a brilliant blue to 

 bluish green, the pronotum sometimes more uniformly olivaceous, 

 and the elytra with a feeble violaceous reflection. The sides of the 

 pronotum are strongly sinuate anteriorly in some examples, whereas 

 in others the pronotum is widest at the middle, and the sides are 

 arcuately rounded. The median depressions on the pronotum are 

 also quite variable in depth, and in some examples are only feebly 

 indicated. The prehumeral carinae are obsolete in some speci- 

 mens, whereas in others they are distinctly indicated. Length. 

 3.75 to 5 millimeters. 



Host. — Unknown. • 



This species was first listed and erroneously identified as viridis 

 Linnaeus by Melsheimer (1806) in his list of Pennsylvania Insects, 

 and Say (1823) described the female from Missouri. Crotch (1873) 

 stated that it was the female of otiosus Say. As it is impossible to 

 recognize the females of otiosus and allied species, I am using this 

 name for a species which is common in the central part of Missouri 

 (type locality of geminatus) instead of describing it under a new 

 name. 



It is very closely allied to otiosus, but in geminatus the male 

 genitalia have the sides nearly parallel to each other and broadly 

 transparent toward the apex, whereas in otiosus the sides of the 

 genitalia are arcuately expanded and not transparent. The females 

 can not be satisfactorily separated from those of the allied species.
