riddle the leaves of many different trees and plants, including (according to 
A. Craw) orange, grape, peach, rose, and others. Unlike what occurs in the 
case of the majority of scarabeid beetles, Adoretus umbrosus undergoes its 
transformation (beneath the soil) at Hawaii in the short period of seven weeks.* 
Likely to be introduced in the grub or beetle condition in the soil of boxes 
containing growing plants, or in decaying vegetable matter from Sandwich 
Islands or from Japan. 
Vine Weevil (Otiorhynchus sulcatus). A small beetle, that when adult 
consumes the leaves of various plants, and that as a larva gnaws their roots and — 
rootlets, injuring in this way not only the vine but various fruit trees. _Intro- 
ducable in soil containing plants cither as a grub or nymph. From Europe 
and South Australia, being already introduced in latter locality.+ 
Vine Weevil (Otiorhynchus picipes, Fabr.). Of like habits. Similarly from 
Europe. 
Burrowing Seale Insect (Chionzspis biclavis, Comstock). A scale insect 
living under the outer skin of the bark, infesting orange, coffee, guava, gar- 
denia, and various shade trees. Introdueable on nursery stock comprising the — 
above plants from the Sandwich Islands, Tahiti, and Southern Mexico. Of. 
‘a cargo of 825,000 orange-trees that arrived at San Pedro (California) from 
Tahiti on 15th June, 1891,” Alexander Craw writes, “The trees were fumi- 
gated five times with double and treble strength hydrocyanic acid gas, and 
dipped twice in a strong caustic solution, with the result that the trees were 
injured, but sufficient scales survived to justify legal proceedings being insti- 
tuted against the trees as a nuisance. . . The trees were destroyed.’ 
Mealy Bugs—(1) Dactylopius vastator, Mask.; (2) Dactylopius ceriferus, 
Newstead. On nursery stock comprising various trees and shrubs; in the 
soil in which plants are being introduced, and in crevices of boxes and packages 
that are used in this connection. From Hastern Asiatic ports, including 
those of China; from the Sandwich Islands and other groups of the South 
Seas.§ Should either of these insects become established here, it is considered 
that the ladybird (Cryptolemus montrouzieri), whose predaceous habits as regards 
mealy bugs were first made known by the writer, would keep it in subjection. 
INSECTS INJURING STRAWBERRY. : 
Strawberry Weevil (Anthonomus signatus, Say.). Feeds as a grub within 
flower-buds, and thus prevents the formation of fruit to the extent of destroying 
one-half prospective crop. In soil whilst hibernating, or about strawberry 
plants. From the United States of America. 
Victorian Strawberry Beetle (Rhinaria perdrix, Pascoe). A weevil the 
grubs of which tunnel in the central shoots of the plant. A “very serious 
enemy of strawberry-growers” (C. French). In strawberry plants. JFrom 
Victoria and Tasmania. 
Strawberry Aleyrodes (Aleyrodes (?) vaporarium). A minute plant-louse. 
occurring on foliage. On strawberry plants and other nursery stock. From~ 
United States of America and elsewhere. It has been already widely 
disseminated, on stove plants, in other countries.

§ Concerning these two scale insects, the following facts have been recorded :— 
“Dactylopius vastator, Mask. Most of the shrubs and trees were so infested by the then 
recently introduced and most’ pernicious of coccids ever met with (Dactylopius perniciosus, Mask.), . 
that their destruction in the near future seemed imminent, had not relief been brought. aie 
The coccid is a native of China, where it had been met with in the neighbourhood of Hongkong.” 
“—A. Koebele, ‘‘ Planters’ Monthly,” Honolulu, Feb. 1897, p. 67. 
“Dactylopius ceriferus, Newst. Another numerous scale insect, and one that had longer — 
been introduced than the previous species (i.¢., D. vastator)—viz., Dact. ceriferus—had always 
been seen covering the leguminous trees, often to such an extent that many of them lost their 
‘entire leaves, and in some ins*ances even were destroyed entirely by the quantities of mealy bugs
