be detected in their work if we heed the castings which are con- 

 spicuous under the infested vine. 



The Bee moth, Gellerea cereana. Too well known wherever the 

 bee is propagated. I need not describe. 



Bee killer, Trupanea apivora. This species of the Asalas family 

 preys on various insects. This species is rather fond of bees. This 

 one captured a bee that was quietly sucking a white clover blos- 

 som. The killer seized the bee by the neck and by elevating the 

 abdomen kept clear of the bee's business end. The struggle was 

 short. The head of the bee was severed and the body quietly de- 

 voured. I noticed that the honey stomach was a tid bit to this 

 hairy murderer. 



The Gooseberry moth, Euphanersa mendica. This moth feeds 

 principally on the leaves of the wild gooseberry, but I have known 

 them to infest Houghton seedling. 



Synchlora rubivoraria. This little pale-green geometer is the 

 parent of the raspberry worm, so annoying to the lovers of this 

 excellent fruit. The larvae attach particles of the fruit to their 

 bodies and rolled up in a ball exceedingly hard to see. Without 

 the greatest care we are in danger of eating these disgusting worms 

 with our dessert. 



I have here two species of Pieris, P. protodice and P. oleracea. 

 The protodice has a bad record with the growers of cabbage. The 

 larva may be described as a soft bluish-green worm with four lon- 

 gitudinal yellow stripes. Length one and one-fourth inches. The 

 sixth, seventh and eighth ring are largest, giving the worm a fusi- 

 form shape. 



Pieris oleracea is abundant at Racine, occurs but little south. 

 The first made their appearance at Racine in 1855, since which 

 time they have greatly increased. The larvae feed on almost any 

 crusifera. Mustard is a favorite food plant. The turnip suffers 

 considerably from this pest. The larva resembles the protodice, 

 but is lighter colored. 



Plusia brassicce does some damage to the cabbage, still it is 

 quite a general feeder. I have seen it on the tomato. The larvae 

 are pale-green and almost diaphanous. They are tender and can 

 be destroyed easily, but it takes sharp eyes to see them. 



Cabbage tenia, Pleutella limbipenella^ is small in size but large 

 in damage. Cabbage infested by the larvae of this small tenia look
