of it ; the elytra are granulated and shiny, with the margin and the 

 suture yellow and a dark spot on the shoulders ; legs pale ; antennse 

 long and dark at the apex. The series in the British Museum shows 

 some variation in regards to markings. 



The larvie have not been described, but they are probably like 

 others of this genus, which have six jointed-legs in front and a projec- 

 tion at the tail end and many tubercles. 



They live in colonies, and when mature fall to the ground to 

 pupate. Two broods at least occur during the year. 



The only treatment which suggests itself is spraying the plants 

 with arsenate of lead as soon as the fruit is gathered, and some 

 treatment of the soil to destroy the pupiv in the ground.

THE STRAWBERRY WEEVIL. 



{Otiorhjjnclins sulcatus. Fab.) 



The strawberry sometimes suffers from this wee^•il in addition to 

 the Eed-legged Weevil (p. 428). 



It damages the plants mainly when in the grub stage, the larvae 

 feeding upon the roots. The beetles also feed upon the leaves and 

 buds. Vines, raspberries, peaches, and many pot plants are attacked 

 by it. 



Amongst other names it is called the Black Vine Weevil. It 

 seems to be more harmful under glass in this country than in the 

 open. 



The weevil, like the other Otiorhynchi mentioned, is wingless 

 and about ^ inch long. In colour it is nearly l)lack ; the thorax is 

 granulated, and the elytra are rough with several raised lines and 

 with scanty pale hair tufts ; the short rostrum has a distinct groove 

 or sulcus in the middle. 



Its life-history is very similar to that of the Eas})berry Weevil 

 (0. picijics) and need not be referred to. 



The same preventive measures as for the latter may be adopted. 



As a remedy for the grubs nothing can be done but forking 

 around the plants to clean the grubs out, and applying heavy 

 dressings of soot well prong-hoed in, or Strawson's vaporite, which 

 I have found quite effectual in killing weevil larvie.
