. Jahresbericht ... des Landwirtschaftsausschusses für das am 30. Juni endende Jahr ... hängen sehr stark von der Glätte des Feldes und anderen Bedingungen ab. Die extreme Schüchternheit der Larve wie auch des Käfers und die geschützte Stellung des Insekts in allen Stadien machen die Anwendung von Pyrethrum, oder jede andere remed^y, die bei Berührung wirkt, völlig nutzlos.das Klee mit London-Purpur oder Paris-Grün zu vergiften, wäre zweifelsohne wirksam, Kann aber nur dort sicher angewendet werden, wo der Cloveris nicht für Futter verwendet wird. Sollte der Phytonomus in einem Feld sehr schlecht sein, wäre es gut, den Klee zu pflügen

. Annual report ... of the Board of Agriculture for the year ending June 30th ... depend very much on the smoothness of the fieldand other conditions. The extreme timidity of the larva as well as of the beetle, and theprotected position of the insect in all stages render the application ofpyrethrum, or any other remed^y acting upon contact, entirely useless.To poison the clover with London purple or Paris green would nodoubt be effective, but can be safely applied only wherever the cloveris not used for fodder. Should the Phytonomus be very bad in a field, it would be well toplow the clover under rather than to allow such field to become asource of contagion. This should be done in the month of May, when the insect is mostly in the larva state, and when all eggs fromthe beetles that hibernated have been hatched. To plow the fieldwhen the Phytonomus is in the imago state would have no other effectthan to disperse the beetles over other fields. 276 VERMONT AGRICULTURAL REPORT. THE VAGABOND CRAMBUS. (Cr ambus vulgivagellus, Clem.) Order Lepidoptera ; family Orambidce.. Plate X. HISTORY OF ITS INJURY AND IDENTICATION. Early in May, 1881, considerable damage was done to meadows inthe vicinity of Watertown, Jefferson Count}T, New York, by an insectwhich was popularly thought to be the Army Worm. In 1882 thisextended into Vermont, and hundreds of acres were injured by thepest, and it was found in all the New England states as well as NewYork. HABITS AND NATURAL HISTORY. The eggs are difficult to find, as they are dropped singly by themoth wherever she happens to rest, and the slightest jar causes themto fall into some crack or crevice. The larvae, if not too numerous, are also difficult to find, on account of their nocturnal habits, butmore particularly from time of hatching to the assumption of the pupastate the}7 remain nearly in the same spot. The newly-hatched larvaspins a delicate white web, near or among the roots of the grass, and commences at once to feed upon the sof
