slight yellowish web, within which they change to pupse. 

 The " hop- vine snout-moth" is of much smaller dimen- 

 sions, with upper wings of a brownish colour, variegated

with a dark line across the middle, and a curved one nearer 

 the base. The larva or caterpillar is green, with a very 

 fine brown dorsal line, and a white one down each side, 

 with scattered black protuberances, surmounted by short 

 stiff hairs. There are two broods of the moth in the season 

 one as early as the middle of April, the other in July. 

 Syringing the bines where the caterpillars have been 

 noticed is recommended by Curtis as a good remedy. 



The "red rust" with which the bines are sometimes 

 infested, and which is by many confounded with the 

 " fire-blast," is occasioned by the existence of minute red 

 spiders the Acarius telarius which take up their quar- 

 ters in large numbers on the leaves, where they spin their 

 fibrous webs. They are generally met with in dry sea- 

 sons ; if their attack be severe the leaves change colour, 

 and eventually fall off from the bines, and as this gene- 

 rally takes place towards the end of August, the flowers 

 as well as the leaves are more or less affected by them, 

 and are proportionately injured. 



Not only are the hops themselves injured by these, and 

 many other insects, no doubt, which have hitherto escaped
