A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 



219 



has been reared from dead branches of southern cypress (Taxodium 

 distichum (Linnaeus) Richard) and persimmon {Diospyros vir- 

 giniana Linnaeus) collected in Virginia by J. N. Knull. Adults 

 have been beaten from oak (Quereus sp.) and wax myrtle (Myrica 

 cerifera Linnaeus) by W. S. Blatchley in Florida. A specimen in 

 the National Museum from Baton Rouge, La., bears the following 

 label : "Bred from dead fig" (Ficus sp.)- 



The color on the dorsal surface of the body varies from purplish 

 black to reddish purple, and the spots on the elytra from golden 

 green through all shades of green to reddish cupreous, and rarely 

 the two apical spots on each elytron are connected transversely. The 

 color on the front of the head in the males varies from bronzy green 

 to bronzy black, sometimes with a distinct golden tinge, and in the 

 females from greenish black, with the punctures purplish, to a uni- 

 form dark-green color. The emargination on the anterior margin 

 of the clypeus is more or less variable in depth. The last visible 

 abdominal sternite in the males is usually shallowly, arcuately emar- 

 ginate at apex, whereas in a few specimens examined it was trun- 

 cate, with the angles acutely produced, and very similar to that of 

 the female, and in other specimens it was simply truncate with the 

 angles not prominent. Usually the females have a distinct, serrate, 

 preapical ridge on the last visible abdominal sternite, but this is 

 obsolete in a few of the specimens examined. The length is from 

 7 to 9.5 mm.
