natural green. Hundreds of scales could be counted upon a single 

 one of its slender leaves. The scales are represented in Fig. 36 in 

 their natural size on the leaves of Pinus strobus, at 2. At 2a, are 

 leaves of the same not stunted by the presence of the scales; 26, a 

 scale of female, of usual form, enlarged; 2c, wide form of the same, 

 enlarged; 2d, a male scale enlarged. The figure is from Prof. J. H. 

 Comstock's Report to the U. S. Department of Agriculture for the year 

 1880, while Entomologist of the Department. 



The species of lady-bug, Ghilocorus bivulnerus Muls., which seems 

 to be specially commissioned to feed upon the eggs of this and other 

 scale-insects, was present upon the trees in great abundance. Its 

 larval stage had already passed, and it was now occurring in its pupal 

 and perfect stages. The larval cases, split longi- yu 

 tudinally upon their back, and disclosing the \*jg&f 

 pupal case within, were quite numerous; as many I .^a fiBHlfc ^J 



as ten of these could be seen upon a single leaf. ^S|L toWB| 

 The larger number of pupse had given out the ^ * v 

 pretty beetle, with its shining blaek wing-covers, JZ^yll^cZ.™- 

 bearing centrally upon each a blood-red spot — coeus bivulnerus: The 

 the two spots suggesting the common name that larva and ima £°- 

 it bears of " the twice-stabbed lady-bird." A few of the beetles were 

 still emerging, with pale ochraceous-colored elytra, and without the 

 least indication of the two red spots which are gradually developed 

 later with the darkening of the wing-covers. In a few minutes time, 

 about one hundred and fifty of the beetles were collected from the 

 leaves and branches of a pine — most of them from the branches, on 

 which they were found quietly resting. 



An examination of the scales upon the more badly infested trees 

 showed that most of them had been eaten into and their contents 

 destroyed. 



From pupse collected and taken to my office, the beetles continued 

 to emerge for about ten days thereafter. 



The Carpet Beetle. 



Anthrenus scrophularice (Linn.). 

 A very early date for the appearance of this beetle abroad is April 

 twenty-seventh, at which time it was found feeding on the pollen 

 of a Crocus, associated with Anthrenus varius Fabr., by Mrs. Hoag- 

 land, of Albany. It seemed to show a preference for the white-
