narrowed at the base and broadening at the tip. It is about 



one-third the length of entire 



antenna. Pedicel obconic, as long 



as the first segment of the funicle. 



Ring joint minute. Funicle 4- 



segmented, the first slightly longer 



than the others, the second, third and fourth subequal. Club 



pointed, about one-half as long as the 

 funicle, distinctly 3-segmented when seen 

 in alcoholic specimens. 



Larva — Length 1.7 mm.; white with 

 brownish jaws (See figure 16). 



Ptipa (newly transformed.) — Length 

 1.5 mm. Colour creamy white. At the 

 base of the abdomen on the dorsal side is 

 a large, oval, orange-coloured area extend- 

 ing on the thorax, apparently caused by 

 the ingested food (Figure 17).

CARNIVOROUS HABITS OF XYLINA BETH U NET; 



G. AND R.*

Field Officer Entomological Branch, Bridgetown, Nova Scotia. 



In working with Xylina bethunei G. & R. the most common 

 fruit worm or apple worm in Nova Scotia at the Dominion Entomo- 

 logical Laboratory at Bridgetown, N. S., in 1913, it was found 

 that the best place to collect 5th and 6th stage larvse was in the 

 leaves about the cocoons of Malacosoma disstria. On opening a 

 few of these cocoons the pupa contained were in some cases found 

 to be partly eaten. A rough opening having been partly eaten 

 and partly stretched through the cocoon from l/3 to ^' of the 

 contained pupa had been devoured. Later on several larvae were 

 found in the act of eating into the cocoons or devouring the con- 

 tained pupa. On July 8, 9, 10, 1913, 160 cocoons of M. disstria 

 were collected from apple trees near the laboratory and 45 of
