chestnut and brown, with yellowish hairs beneath, and is 

 nearly an inch in length. Its scientific name is Lachnosterna 

 fusca, or, literally translated, the brown woolly-breasted beetle. 

 The pupa (fig. 2) with that of the larva taken from the 

 "Guide to the Study of Insects" is white. 



The Goldsmith Beetle. — We also have in this State an 

 insect allied to the preceding, and with much the same habits, 

 both in the adult and preparatory states. It is the Cotaljpa 

 lanigera (fig. 5). It is nearly an inch in length, bright yel- 

 low above, with a golden metallic lustre on the head and 

 thorax, while the underside of the body is copper-colored, 

 and densely covered with white hairs. 



Dr. Harris says that it is very common in this State, 

 remarking that it begins to appear in Massachusetts about the 

 middle of May, and continues generally till the twentieth of 

 June. "In the morning and evening twilight they come forth 

 from their retreats, and fly about with a humming and rust- 

 lins: sound amono; the branches of trees, the tender leaves of 

 which they devour. Pear-trees are particularly subject to 

 their attacks, but the elm, hickory, poplar, oak, and proba- 

 bly also other kinds of trees, are frequented and injured by 

 them." Dr. Lockwood has found it on the white poplar of 

 Europe, the sweet-gum, and has seen it eating the Lawton 

 blackberry. He adds that the larvae of these insects are not 

 known ; probably they live in the ground upon the roots of 

 plants. 



It has remained for the Rev. Dr. L. Lockwood to discover 

 that the grub or larva of this pretty 

 beetle in New Jersey devastates straw- 

 berry-beds, the larva feeding upon the 

 roots, in the same manner 

 as the May beetle. His 

 account was first published 

 in the "American Natural- 

 ist," (vol. II. pp. 186-441). 

 He says that in the month
