[239.] 324. Arthromacra donacioides Kirby. — Length of body 

 5 lines. Taken in Canada, near Lake St. Clair, by Dr. Bigsby. Speci- 

 mens also from Massachusetts. 



Body black-bronzed with a greenish tint, glossy, with the whole upper 

 surface thickly aud irregularly punctured ; underneath, except the sides 

 of the trunk, impunctured. Antennae much longer than the head and
