OF INJUKIOUS INSECTS.- 
43 
number of synonyms for tlie common Slug-worm, and also the doubts 
as to whether .two species do not really pass under one name, make 
the subject rather difficult; but the above description will convey the 
general appearance of the larva, sometimes so injurious to the Pear 
leaves. 
28. Nematus Iiibesii. Gooseberry and Currant Sawfiy; Gooseberry 
Caterpillar. This Sawfiy is oclireous, with an orange-colbured body; 
the wings iridescent, with brown nervures. The larvae, when about 
three-quarters of an inch long, are dull pale green, with the segments 
next to the head and tail of a deep yellow; head, feet and tail black, 
and black spots on each segment, sometimes arranged in rows down 
the back. When full grown the caterpillars cast their skins, and 
appear of a uniform pale green, and still with the yellow segments, 
but without the black spots, excepting two little black dots on the 
head. They go down into the earth to change, and spin a yellow- 
coloured cocoon, as previously mentioned, from which the summer 
brood hatches in about three weeks; but the autumnal brood lies 
unchanged, buried in the cocoons in the earth till the following spring, 
when they develop as the Gooseberries and Currants come into leaf. 
30. Retinia Turionana. Pine-bud Tortrix. This moth is somewhat 
under an inch in the expanse of the wings; the fore wings bright 
orange, with several irregular or bifid transverse silvery streaks; the 
hind wings dusky lead-colour. The larva is glossy, of a dark purplish 
brown; the head, and transverse patch on the second segment, black. 
When full fed it turns to pupa in the Pine-bud, on which it has been 
feeding. Various species of Pine-bud Tortrix are injurious to Pines, 
and remedies found to be of practical use would be of great value. 
The species named is sometimes injurious in England, but not 
generally so much so as other species of Retinia; it is selected that we 
might have the advantage of the figure of a type of the genus, and its 
method of injury. 
31. Hylobius Abietis. Fir Weevil. A pitchy black Weevil, about 
half an inch in length, mottled with irregular wavy bands of downy 
yellow on the upper surface, and so much rounded at the sides as to 
be almost cylindrical. This Beetle is furnished with a long thick 
proboscis, and thence occasionally bears the name of Elephant Beetle. 
32. Hyluryus Piniperda. Pine Beetle. This minute Beetle is only 
from one to two lines long; black, slightly downy, with pitchy legs, 
and dull red antennae. 
It now remains for me to express my hope that those who have 
hitherto assisted will continue their contributions for the next year’s
