596 TRANSACTIOXS OF THE 



similar to that of the linearis F., of Austria, which it very much 

 resembles. 



3. A. POLiTUs nob. — Much like arcuatus, but a little more ro- 

 bust, and of a brilliant color. Like the other species its elytra 

 are denticulated at tip. Having examined numerous specimens, 

 I find that it is not of a larger size than geminatus. 



4. A. ARCUATUS nob. — A little larger than geminatus, and re- 

 sembling it in the character of the elevated line at the posterior 

 thoracic angles, but the antennga are much more slender and 

 ■elongated. 



5. A. GRANULATUS nob. — This species has three hardly visible 

 fulvous spots on the elytra ; one on the depressed base, one near 

 the suture before the middle, and one behind the middle, also 

 near the suture. I have a specimen in which these spots are 

 not at all visible. 



The elevated line at the posterior angles of the thorax is short, 

 but very obvious. 



6. A. BiLiNEATUS Weber, nob, — In my printed description 

 an error occurs. When describing the elytral vittae, instead of 

 " extended towards the tip, where it gradually approaches the 

 scutel," I should have said suture instead of " scutel." 



7. A. LATERALIS nob. — I stated in the description that the 

 elytra are entire ; I would add that they are not obviously denti- 

 culated at tip. 



8. A. pusiLLUs nob. — The smallest North American species I 

 have yet seen. 



The above species of Agrilus, excepting the first, I described 

 in the Journal Acad. Nat. Sc, and the Annals of the Lyceum of 

 Nat. Hist., of New York, under the genus JBtiprestis, to which 

 most entomologists yet refer their kindred species. [163] 



9. A. FALLAX. — Elytra with about three spots on each, which 

 exhibit a different reflection. 



Inhabits Indiana. 



Brassy -greenish : head green, sometimes cupreous on the ver- 

 tex ; impressed line hardly obvious : thorax with a dorsal and 

 lateral indented line ) the former more obvious behind, the latter
