In consequence of the description of Arthromacra robinsoni^ 

 Mr. Schwarz called my attention to certain specimens in the U. 

 S. National Museum remarkable for their vestiture of long thin 

 hairs, collected by the late Hugo Soltau at Nashville, Tenn., 

 which evidently represent a new species. In searching for addi- 

 tional material I found one more of the Nashville specimens in 

 the Joutel collection, and representatives of still another new 

 species in the American Museum, collected by Wm. Beutenmiiller 

 in the mountains of North Carolina. The remarkable elongation 

 of the last joint of the male antennae, characteristic of the 

 Lagriidse, is to be seen in these new species, varying in degree 

 with each as in the species of the allied genus Statira; and varia- 

 tions in color, in the punctuation of the pronotum, and in the 

 relative length and width accompany the more obvious characters 

 first mentioned. It is interesting to note that the genus Artho- 

 inacra, widely distributed and known in our northern regions by 

 the species aenea should have three species and two varieties near 

 its southern limit as shown by the following synopsis. 



Synopsis of the Species of Arthromacra. 



Upper surface glabrous. 



Thorax distantly punctate; color brilliant green; last joint antennae 3 



as long as six preceding joints combined; 11 mm.; Va robinsoni. 



Thorax confluently punctate; color aeneous bronzed; last joint antennae 

 (S as long as three preceding joints combined; 12-14 mm.; N. E. U. S. 

 and Can. aenea. 



Elytra with a few long, thin hairs. 

 Thorax coarsely, confluently punctate; color bright green above, ab- 

 domen bronzed, tibiae and tarsi testaceous; antennae J' unknown; lo-ii 

 mm. ; Mts. of Va. and N. C. appalachiana. 



Upper surface of thorax and elytra clothed with long, thin hairs. 

 Thorax coarsely punctate; color greenish or greenish coppery bronzed; 

 abdomen darker, tibiae and tarsi pale; last joint antennae 3 as long as 

 five preceding joints combined; 11-12 mm.; Tenn. pilosella.

Since recent studies have disclosed the presence of elytral hairs 

 in two species of the genus I have reexamined my series of 

 robinsoni and find in some specimens a few hairs near the apex 

 of the elytra, not enough to cause any confusion with appalach-
