Mr. Maskwick's Obfcrvationt On the Clover tVeevll. 143 



and, as I at firft imagined, no legs ; but I have fince difcovered, on 

 a clofer infpection aflifted by glafles, near the head, three fmall white 

 fcales or prominences on each fide, which I fuppofe may fupply the 

 place of legs, in this minute infedt. SeeTAE.V. fig. a. A. I traced it 

 through its chry falls to its imago or perfe<ft ftate, in the following 

 manner. Having placed a number of the blighted heads of the 

 clover in a box, which was carefully covered with gauze to prevent 

 any infefl from getting jsjther in-orout, I found, on opening the 

 box on the 19th of the fame month, a great number of fmall black- 

 ifh weevils running about in it, and on infpedlion dilcovered manv 

 of their chryfalids, (licking to the ftem at the bafe of the mdividual 

 floret, exactly in the fame fituation as I had before found the larvae ; 

 nay, 1 even law one or two of thefe weevils crawl out from their 

 chryfalids. 



Under Aefe circumftances there can be no doubt that the be- 

 fore-mentioned larva changes to a fmall white chryfalis, which dif- 

 fers but little from it, except in being egg-fliaped and morionlefs; and 

 this produces a fmall blackilh weevil with a long beak, whitifb 

 belly, and yellow legs. 



W4th regard to the quantity of damage done by this little de- 

 ftrudlive infefl', I know of no better way of afcertaining it, than by 

 taking a comparative view of two of my crops, which grew in two 

 fields adjoining to each other,,a"nd which appeared to be equally good 

 with refpetSl to the growth of the plan's, but very different in the 

 produce of feed: this will leave but little doubt that the deficiency 

 of this year's crop has been occafioned by the devaftations of thefe 

 infecls, which abounded in an aftoniftiing degree. This I fhall do 

 with as much accuracy as I can. 



In the year 1798 I grew on nine acres of ground (juft double the 

 quantity that was faved for feed this y€ar) either thirty-three or 

 thirty-four bufliels and a half of clover feed, of which twenty-eight
