 6. The shout-lined dularius. 

 Dularius brevilineus Say. 

 Order Coleoptera; family CERAMBYClDiE. 



Fig. 13.— Dularius brevilineus. — From Packard. 



Boring in partly dead or dry elms, the larva of a pretty longicorn, with deep pur- 

 plish-blue wing- covers bearing three short white lines in the middle. 



This beetle was first bred from the dry wood of the elm by Riley, the 

 larvie occurring in Ohio; the beetle appearing in May and June. It 

 was also known, by the late Mr. G. D. Smith, to inhabit this tree, 

 probably in the vicinity of Boston; it was noticed in our second Massa- 

 chusetts Report, page 18. Mr. George Hunt has observed this beetle 

 on the bark of an elm at Plymouth, N. H., in the middle of July, insert- 

 ing its eggs in the crevices of the bark. 



The beetle. — It is a singular-looking beetle, with a round, flattened prothorax, and 

 wing-covers contracted in the middle, and not covering the tip of the abdomen, while 

 the thighs are unusually swollen. The autenn;e are about two-thirds the length of 

 the body, flattened towards the end, and somewhat serrate. The body above is 

 velvety black, and brown-black beneath. The head is black and coarsely punctured, 

 and the prothorax is covered with short, dense, black hairs, like velvet. The wing, 

 covers are Prussian blue in color, bent, corrugated, with au interrupted ridge just 

 outside of the middle of each cover. They are covered with tine black hairs, bent 

 over. There is a pair of parallel, short honey-yellow lines in the middle of each 

 wing-cover, with a third one a little in front, making in all six streaks. The legs 

 and feet are black. It is a little over eight-tenths of an ineh in length. 



7. Neoclytus erythrocephalua Fabricius. 



Order Coleoptera; family Cerambycid.e. 



This insect was found in company with Magdalis armicollis under the 

 bark of a dead elm at Detroit, Mich., by H. G. Hubbard ; and also has 

 been raised from hickory- wood by Dr. Horn.
