designating this specimen as the neotype, and depositing it in the 

 United States National Museum collection. 



Type localities. — Of fattax, Indiana; the t}^pe is lost. Of zemes, 

 Alabama; present location of type unknown to writer. Of impres- 

 sipennis, Baltimore, Md. ; present location of type unknown to 

 writer — probably is lost. 



Distribution, — This species is widely distributed and material has 

 been examined from the Province of Quebec, Canada, and various 

 localities in the following States: Alabama, Connecticut, Delaware, 

 District of Columbia, Florida, Illinois, Indiana, Iowa, Kansas, Louis- 

 iana, Maryland, Missouri, New Jersey, New Mexico, New York, 

 North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, 

 Tennessee, Texas, Virginia, and West Virginia. 



Variations. — The color varies from olivaceous green to reddish 

 cupreous, and the length from 4 to 6 millimeters. The pronotum is 

 usually widest near the apex, but in a few examples it is widest at the 

 middle, and the sides are arcuately rounded. The median depression 

 on the pronotum is quite variable, and may consist of a rather deep 

 depression posteriorly, two vague median depressions, or a feebly 

 impressed median groove, and rarely an example is found without 

 distinct depressions. The pubescent spots are sometimes only feebly 

 indicated, but this is usually due to abrasion. 



Hosts. — Has been reared a number of times by different workers 

 from dead and dying honey locust {Gleditsia triacanthos Linnaeus) 

 and hackberry (Oeltis occidentalis Linnaeus). It has also been re- 

 corded from black locust, oak, and cottonwood, but these records are 

 probably incorrect. 



This species resembles obsoletoguttatus Gory very closely and the 

 two species are confused in most collections. It is usually smaller 

 than obsoletoguttatus and has the prosternal lobe broadly rounded in 

 front, whereas in obsoletoguttatus the lobe is emarginate in front.
