Mr. Butler kindlyprovided the society with a liberal supply of specimens for its collection. There are two speciesof injurious asparagus beetles, Crioceris asparagi, Linn,, and G. 12-punctatus, Linn., and they-differ considerably in their appearance, and to some extent in their habits. Crioceris asparagi. 60 THE REPORT OF THE No. 19 has been on the Canadian list, as having been known to be taken in Canada for fourteen yearsor more, but it has not yet been reported as having been seen in this city or vicinity, whilstC. 12-punctatns will soon prove itself to be the more abundant and destructive species of thetwo. Mr. E. M. Walkers observations on the spreading of Pieris protodice (Fig. 37) eastward,given in the Thirty-second Annual Report of the Entomological Society of Ontario, page 87, aroused my interest in that butterfly, and I requestedthe collectors in London to be on the look-out for it ;but it was not observed here by any of them. Theseason was unfavorable for rapae (Fig. 23), as it wasnot nearly so plentiful as in ordinary years, and lbmay well be regarded as yet more unfavorable forprotodice^ which has been designated The SouthernCabbage Butterfly.
