INJURIOUS TO FARM AND GARDEN PRODUCE. 



warts and yellow legs. They reach maturity in from four to six 

 weeks. 



The pupa is fixed to walls of outhouses, fences, the plants, stones, 

 etc. It is variable in colour, and can withstand great cold. 



Many of the caterpillars examined in 1910 were parasitized by 

 a small hymenopterous fly, Microgasier glomcratus, Linn. 



PREVENTIVE AND REMEDIAL MEASURES. 



Cabbages and other plants may be sprinkled with finely-ground 

 lime, or if ready to cut sprayed with salt and water. 



All chrysalids should be destroyed. A few days rain will kill 

 thousands of the caterpillars ; in its absence a good drenching of 

 water with a garden hose will do much good. 



THE GARDEN SWIFT MOTH. 



Hepialus lupulinus, Linn. 



The caterpillars of this moth are frequently the cause of con- 

 siderable damage to bulbaceous plants. I have numerous records 

 made during 1910 of their attacks on paeonies, also potatoes and 

 winter beans. 



LlEE-HlSTORY. 



The perfect insects appear towards the end of May, and may be 

 seen rapidly darting about over hedgerows, grass, etc., at dusk as 

 late as the end of July. 



The eggs are dropped on the ground by the female as she flies, 

 and hatch in from nine to twelve days. 



On emerging from the egg 

 the young caterpillars make their 

 way into the soil, and at once 

 commence feeding upon the roots 

 of various plants, and continue 

 to do so until the following 

 April. In mild winters they 

 do the most damage, continued 

 extreme cold driving them into 

 the deeper soil, where I have 



taken them at a depth of 18
