Red-headed wood-pecker is much 

 scarcer now than five years ago, when 

 they were extremely common, as now 

 but few are met with in our woods. 



On examining a tongue of each of 

 the above species, I find the Melauer- 

 pes-erythrocephalus, No. 406, had a 

 horney tip very acute and sharp with 

 eleven spines on each side and five- 

 eights of an inch in length ; whole 

 tongue with bony rods five inches. 



Melauerpes- Carolinus, No. 409, 

 had five-eights of an inch horney tip, 

 broad and flat with numerous hair-like 

 spines on each side ; total length of 

 tongue being five inches. 



Dryobates- Villosus, No. 393, had 

 tip three-eights of an inch long, with 

 seven hair-iike spines on each side ; 

 probably more as some of the hair- 

 like spines had been scraped off in 

 cleaning tongue ; its total length 

 being four and three-quarter inches.

The Imported Cabbage Worm. 



Pieris rapce Linn. 



This insect was imported from 

 Europe into Canada about thirty-six 

 years ago. It spread rapidly in all di- 

 rections, and now is found in injurious 

 numbers from the Atlantic to the 

 Pacific, and, through the Northern 

 States, at least, is the most destruct- 

 ive insect attacking cabbage and cauli- 

 flower. 



The mature insect is a white butter- 

 fly. It measures a trifle over 1^ 

 inches from tip to tip of the front 

 wings when spread, the female being 



a little larger than the male, as is 

 usually the case among butterflies and 

 moths. As seen from above, the body, 

 bases of the wings and the tips of the 

 fore wings are black or blackish in 

 both sexes. The female has, a little 

 beyond the middle of the fore wing, 

 two black spots, and there is another 

 spot in line with these on the anterior 

 border of the hind wing. On the un- 

 der side, the female has two black 

 spots on the fore wing, and the tip of 

 the fore wing and the entire surface of 

 the hind wing are sulphur yellow. 



The male differs from the female by 

 having but one black spot on the fore 

 wing above, and being a little whiter 

 in color. These butter-flies appear 

 early in the spring, and the female is 

 ready to deposit eggs for the first 

 brood of worms as soon as early cab- 

 bages are transplanted into the gar- 

 dens. The eggs are elongate, yellow- 

 ish white objects, and just large 

 enough to be plainly seen with the 

 naked eye. They are deposited singly 

 during daylight, and nearly always 

 upon the outer surface of the spread- 

 ing leaves and not upon the cabbage 

 head. When the butterflies are flit- 

 ting abundantly over the cabbages, a 

 moment's watching will be rewarded 

 by seeing one or more of these eggs 

 deposited. In a very few days the 

 eggs hatch, and the little green worms 

 begin to feed upon the leaves. They 

 gradually work inward to the head, 

 and late in the season a large number 

 of worms that are half grown or more 

 may be found eating into the base of
