BI'BIO ma'rci, St. Mark's Fly. Mr. 

 Curtis says : " The larvae, or grubs, of 

 this insect generally live, in large groups 

 of a hundred or more in strawberry- 

 beds, vine borders, flower pots, and simi- 

 lar undisturbed spots, feeding upon the 

 roots, and sometimes destroying the en- 

 tire plant. Bouche says they completely 

 demolished his bed of Ranunculuses for 

 several successive years, by eating up 

 the tubers. The larva is dark brown, 

 somewhat cylindrical, the belly flattened, 

 moderately broad, and nearly linear ; the 

 V 



head is comparatively small, deep brown, 

 and very shining. It changes to a chry- 

 salis generally towards the end of March ; 

 this is of a pale ochreous colour, the head 

 being brightest. The female lays her 

 eggs in the earth, and in the dung of 

 horses and cows, in May ; they do not 

 hatch until August."

 a tooth; in reference to the seed. Nat.

 common border. The others are scarcely 

 worth cultivating, but we have named 

 the best. The annuals and biennials 

 from seed, and the perennials by division 

 and suckers. All hardy, except when 

 otherwise specified.
