NOTES OF OBSERVATIONS 



INJURIOUS INSECTS 



COMMON CROP PESTS 



During 1891. 



APPLE. 



Apple Sawfly. Tenthredo (Hoplocampa) testudineaj Klug.* 



Tentheedo (Hoplocampa) testudinea. 



Female Sawfly and caterpillar, magnified, with lines showing nat. size, after Prof. 

 J. 0. Westwood ; t caterpillars nat. size, and infested Apple. 



Attack of Apple Sawfly caterpillars has not been much reported 

 up to the past season, but from last summer's observations it seems 

 probable that this infestation is more prevalent than is commonly 



* From the appearance of the caterpillar of the Apple Sawfly, and likewise from 

 its habits and the characteristics of the attack, it scarcely appears open to doubt 

 that it is the larva of the Tenthredo {Hoplocampa) testudinea, Klug; but as we have 

 not as yet reared the perfect insect (the time not being yet come for its development 

 from our specimens), I give the scientific name with a note of interrogation.
