120 THE CANADIAN ENTOMOLOGIST. 



farmer with many useful and active assistants in the shape of various pre- 

 daceous insects. Conspicuous amongst these are the Ground Beetles, 

 which should be known by sight by every one, so that they may be pro- 

 tected, and not, as is too often the case, destroyed because they are insects. 

 At Fig. 6 is shown the " Fiery Ground Beetle " ( Calosoma calidum Fab.),, 

 a common and very useful species. Its colour is deep black with red 

 (or sometimes green) glowing spots. The grub has been styled the 

 "Cut-worm Lion," on account of its useful habit of destroying these pests.

AN EARLY BUTTERFLY. 



Dear Sir : While driving in a cutter on 12 th March, my attention 

 was attracted to a butterfly fluttering around a farmer's house. Seeing it 

 alight, I attempted to capture it, but although 1 got near enough to make 

 sure it belonged to the genus Grapta, it rapidly flew across a wide field 

 of deep snow and easily eluded pursuit. The weather was mild, and as 

 far as my experience goes, this species is the earliest butterfly to appear 

 in our vicinity ; but I consider this particular record as somewhat remark- 

 able even for Grapta.

CAPTURES AT MONTREAL. 



Dear Sir : During the past summer a few butterflies have been taken 

 here which are perhaps worth noting. I took a Pieris jiapi oleracea on 

 May 21, and half a dozen Pyrameis himtera and two P. cardui one 

 afternoon in September. Oleracea is very local and has almost dis- 

 appeared. Himtera is very rare, one or two specimens perhaps beinsj 

 observed each year, and cardui has been scarce since 1884, when the 

 species appeared in great abundance. A specimen of Feniseca Tarquinius 

 was taken in June and two in July of the previous year (1887). These 

 are the only instances of its occurrence here.
