 Injurious Insects, p. 89. 



Fabricius did not know tbc native country of the specimen he described, but as he 

 refers to a collection which was rich in North American species, I have no doubt of the 

 correctness of this determination. It appears, from Dr. Harris's account, to be common 

 in New England, where it is destructive to apple orchards. Dr. Melsheimer has a speci- 

 men, taken in Pennsylvania, which is the bifasciuta of his father's catalogue, No. 783.

Nigropiceoua, shining, sparsely covered with pale, fulvous hair; apex of the elytra with a large, circular, 

 common, holosericcous macula. 5j '" long; ljwide. Inhabits Pennsylvania. 



Head, prothorax, pleura, and elytra with Impressed, dilated punctures: front convex, eyes black: prothorax 

 widest behind, punctures confluent upon the sides; scutel wide and short: elytra square at base, where the 

 punctures are large t, a little wider than the prothorax, tipped with a large, black, circular spot, which is 

 bounded posteriorly by thickly-set, palcycllowish hairs: venter shining black, particularly three spots upon 

 each side, which arc divested of hair. 



The terminal black Bpot gives the elytra the appearance, on a casual view, of a deep 

 emargination, as in Tomicus.
