characters are treated in the 13th report of this office, pp. 141, 142 
and 143. These are the strawberry crown-miner (Anarsia lineatella) 
— easily recognized as a slender, reddish caterpillar with numerous 
short legs — and several beetle larvae similar in form to the crown- 
girdler, but somewhat smaller when adult. One of the most im- 
portant of these is the true strawberry crown-borer (Tyloderma 
fragaruu), also a footless grub, which mines the interior of the 
crown, within which it changes to the pupa. The crown-girdler, on 
the other hand, feeds mostly externally on crown and roots, and 
pupates in the earth near by. Very similar in habits to the crown- 
girdler are the three species of strawberry root-worms (Typoph- 
oriis cancllus, Colaspis brunnea, and Scelodonta nebulosus), all 
larv?e of the plant-beetle family Chrysonielidcc; but these all have 
a pair of small but distinct legs on each of the three segments 
just back of the head. 
The mature larva forms a cell in the earth near by, where 
it changes to a whitish inactive pupa, which in about ten days 
becomes an adult. 
Fig. 23. Strawberry Crown- 
girdler, Otiorhynchus ovatus, 
adult. Length about one-fifth 
inch. 
The adult (Fig. 23) is a black snout-beetle, or weevil, about a 
fifth of an inch long, with a short, thick snout or beak. The straw- 
berry crown-borer is also a snout-beetle, but has a slender Ijcak. 
The crown-girdler adult is easily recognized, also, by its curiously 
globular thorax and egg-shaped hind-body, in conjunction with its 
black color and its wrinkled, uneven surface, all well shown in the 
figure. These beetles hide by day about the summit of the crown, 
forming burrows about the loases of the leaf-stems for convenient 
access, and feed by night on the leaves, eating small, irregular
