pupee within eight to twelve days, the beetle issuing in July or 
August. Only one annual generation is recorded, the beetle 
hibernating. Phytonomus murinus Fabr., oviposits on the young 
shoots of Lucern (Medicago sativa); Ph. meles Fabr., feeds as 
larva and beetle on 7rifolium pratense and Lucern, and proves in- 
jurious to the latter plant in some parts of Germany; /%. nigrt- 
rostris Fabr. (which, by the way, occurs also, though rarely in 
the United States, from Canada and Massachusetts westward to 
Michigan), feeds as larva on 7rifolium pratense and Buphthalimum 
Salicifolium; Ph. pollux Gy\lh. on Silene inflata and Polygonum 
hydropiper ; Ph. rumicis Fabr., on various species of Rumex an 
also on Polygonum aviculare ; Ph. vicie Gy\\h. on Vicia sylvatica ; 
Ph, plantaginis DeG. on Platago lanceolata and Lychnis dwica ; 
Ph, polygoni Linn., on young shoots of Dianthus and on Polygonuim 
aviculare, the larve feeding on the leaves as well as on the 
blossoms and also boring in the stems; /%. suspictosus Hbst., 
on Lotus uliginosus and Lathyrus pratensis; Ph. palumbanus 
Germ., on Mentha aguatica and Salvia glutinosa, So far as 
known, the habits of the genus in this country conform to the 
above experience in ._ We have reared Ph. comptus Say, 
from Polygonum nodosum upon which the larva and pupz may 
be found in July, the cocoon having the usual net-work ap- 
pearance. Of the nine species known to occur in this country 
(exclusive of Ph. punctatus) this is the only one whose habits 
ve been observed, though, as above shown, those of Ph. nigri- 
vostris have been recorded by European observers. : 
We had the pleasure of spending some time about the middle 
of August with Mr. L. D. Snook at Barrington, N. Y., who has 
: suffered materially from the attacks of Pytonomus punctalus, and 
_ SiMce—though it is so common abroad—little or nothing is on 
_ fecord of its habits, and since it has certainly never before been 
Feported as injurious to agriculture, we give Mr. Snook’s experi- 
_ _€Nce up to the time of our visit. In the latter part of April, he 
_ -Btst noticed on a field of clover here and there, small patches 
: where the leaves were badly eaten. The damage increased rap- 
ae idly in extent, and by the end of July, the whole field {about
