STATE IIORTICLLTURAL SOCIETY. 193 



Agrihis lateralis, Say. 



The genus or group to which this belongs is easily distinguished 

 from other Buprestians by the elongate, slender and cylindrical body, 

 and small size, the largest species being less than half an inch long. 



This species, which I have found in considerable numbers in the 

 southern part of the State, is a pretty little insect, very narrow, sub- 

 cylindrical', and about one-fifth of an inch in length. The front of the 

 head is a dark, dull, coppery color, and the thorax of a dull, brassy color 

 throughout. Wing-cases narrow, nearly parallel, and black. 



I have found it in considerable numbers on white and post oak 

 bushes, also on various wild flowers ; but I have not been able to identify 

 the larva. Dr. Harris ^ys that the larvae of the species, belonging to 

 this genus, are similar in form to those of the slender, cylindrical Saperdas, 

 and that they have the same habits, living in the center of stems and 

 devouring the pitch. It is very probable, therefore, that this, when its 

 transformations are carefully traced, will be found similar to the following 

 species. 



Spec. Char, /w;?;,'-^.— Hind coxal plates but little widened at their inner extremities. 

 Thorax angulated behind. Scutelium distinct. Body not hairy. I'rosternum without 

 grooves for the reception of the antennx". General color black ; head and thorax dull, 

 brassy— the former canaliculate, the latter with a posterior dorsal and anterior lateral 

 indentation. 



Body elongate, black, scabrous. Head dull, brassy, superficially punctured; a 

 profoundly impressed line, abbreviated before. Antenna.' blackish. Thorax dull, brassy, 

 somewhat scabrous; around, indented spot behind the middle, and an oblique, pro- 

 found, oblong one each side, at the anterior termination of which the thoracic edge is 

 dilated ; basal edge sinuous. Scutel black, sub-triangular. Elytra scabrous, entire, 

 slightly indented at the base. Tail rounded. 



Length, one-fifth of an inch. 



Distinguishable by the dilation of the lateral thoracic edge. 



Agrilus ruficollis, Fabr. The Raspberry-cane Borer. 



This is a small, slender, sub-cylindrical species, about one-fourth of 

 an inch long, and scarcely more than one-fourth as wide. It has received 

 its name, ruficollis or red-neck, in allusion to the brilliant coppery color 

 of its head and thorax ; yet there are some varieties which have the 

 thorax of an obscure green, while in others it is of the same dark color 

 as the wing-cases. 



The following are the distinguishing characters : Head and thorax 

 of a brilliant coppery color. The head is quite broad as compared with 

 the thorax, which it equals, but the length is scarcely more than a third 

 the width, deeply immersed in the thorax. Form of thorax and body 

 similar to the preceding; the head similarly indented. The elytra are 

 somewhat rough, and at the tips are serrate ; black or tinged with a dull 

 coppery color. There are some varieties which have the thorax of an 

 obscure green, while in others it is of the same dark color as the elytra. 



Length about one-fourth of an inch ; width but little more than one- 

 fourth the length.
