domeii being in triangular spots on sides of ventral segments. Occiput with 

 a more distinctly impressed median line. Elytra with an indistinct costa, 

 between which and suture the surface is broadly grooved; tips ending in a 

 short, sharp spine and unevenly toothed. Length 8-12 mm. 



Warren and Posey counties; scarce. June 9-July 23. Occurs 

 only on the hackberry, CeUis Occident aUs L., in the twigs of Avhich 

 the larvae bore. 



1514 (4721). Agkilus buficollis Fab., Ent. Syst, I, 1798, 214. 



Elongate. Black or bluish-black ; 

 head and thorax usually bright cupre- 

 ous. Occiput with a deep median fur- 

 row, somewhat strigose. Thorax broad- 

 er than long, apex slightly wider than 

 base ; disk with a rather deep oblique 

 depression on each side, and a feeble 

 one in front of scutellum ; surface faint- 

 ly strigose and rather densely punc- 

 tate. Elytra a little broadened behind 

 the middle, nearly concealing the sides 

 of abdomen from above, tips rounded, 

 distinctly serrulate ; disk flat a basal depression on each side; surface with- 

 out trace of carina?, closely granulate. Prosternum obtusely lobed in front. 

 Length 5.5-7 mm. (Fig. 308.) 



Throughout the State; common. May 18-July 22. Occurs on 

 the foliage and stems of blackberry and raspberry bushes, in the 

 canes of which the larvae bore, forming galls on some varieties. 

 These should be cut out in winter and burned with the enclosed 

 grub ; or the shoots made up to the first of July should be cut off at 

 the surface, because in them the larvae of a new brood are con- 

 tained. The shoots formed later in the season will be sufficient for 

 the next year's crop of fruit. 



A. crmicomis Horn, length 4.4 mm., is known to occur in Ohio 

 and Illinois; A. lateralis Say, head and thorax cupreous, elytra 

 black, with slight bronzed lustre, length 6-7 mm., is known from 

 New England, Illinois and Missouri.

Elongate, slender, male sometimes linear. Dull greenish or slightly 

 cupreous ; front of head, sides of thorax, antennae and under surface usually 

 bluish or greenish. Occiput with a slight impression ; lower part of front 

 usually with dense whitish pubescence. Thorax a little wider than long; 

 hind angles indistinctly carinate, male, or with a well defined carina, fe- 

 male; disk with an oblique depression each side and two on median line, 

 the hind one the larger ; surface transversely strigose with fine punctures 

 between the wrinkles. Elytra with a vague costa from the humeri to be-
