afterward, until the 28th, when it began moving rapidly around in the 
bottle in which it was confined 
From these observations it may be concluded that the inscct norm- 
ally passes some time after transformation in comparative inactivity, and 
probably does not issue from the wood in which it breeds until at least 
two weeks after arriving at maturity. 
A. viridicornis Say.—Observed on elm leaves June 11th—18th. 
A. viridifrons is noted as occurring on elm also (Ent. Am. vol. V, p. 31). 
A. cyanella Gory—-Bred from chestnut twigs. May rith. 
A, quercata Fab.—Observed on leaves of chestnut and chestnut 
oak during June and July. 
For convenience I have assumed that the species of Anthaxia above 
mentioned are distinct, though there are good reasons for the belief that 
wridifrons and viridicornis are sexes of a single species, and cyanel/a and 
quercata constitute in like manner another species. 
Chrysobothris femorata Fab.—To the list of half a dozen trees 
noted as being infested by this species I add hickory, having cut the 
imago from the larval passages in the wood. It was taken during the 
past season at Staten Island on a log of white birch, May 17th and I 
have no doubt it breeds in this wood also. 
C. dentipes Germ. — From the uniformity and frequency of the oc- 
currence of this insect on pines, it is doubtful if it breeds in any but 
coniferous trees, although Harris (Ins. Inj. to Veg. p. 49) states that it 
inhabits the trunk of oaks / 
C. sex-signata Say.—One specimen cut from a beech tree in which 
it had bred. -In the list previously referred to (p. 31) this species is 
mentioned as having been beaten from pitch pine. 
C. agurea Lec. —Taken by Mr. A C. Weeks on dead sumach (Rhus 
toxicodendron) on Long Island and Staten Island, N. Y. in June. 
Acmeéodera culia Web, like other species of the family is peculiarly 
asun beetle. I have repeatedly examined the flowers of Geranium ma- 
culatum in the shade without ever discovering a single specimen, while 
the flowers that were exposed to the sun fairly swarmed with the little 
beetles. They eat the petals of this plant and of the wild rose also. June 
and July. 
Agrilus egenus Gory.—Bred in great numbers from the twigs and 
smaller branches of the common locust tree (Robinia pseudacacia). The 
larvee form mines under the bark, eating both bark and wood. Some 
little time is required by the imago to issue from the wood. On one oc- 
casion, May 8th, many specimens were observed with their heads, and 
in some cases, thorax and anterior legs projecting from the bark, and 
some were still to be seen in that position two days later. Of the beetles
