Agathis. An Ichneumon, C re mast us retiniae Cress., was reared 

 from this insect by Messrs Riley and Howard. The writer also succeeded 

 in breeding from this insect an exceedingly small four winged fly which 

 was determined by Dr Ashmead as a species of Stenomesius.

Pitch midge 

 Cccidoniyia rcsiiiicola Osten-Sacken 



Footless orange grubs occur in clear or whitish pitch masses on the underside of 

 pitch pine branches. 



This interesting insect has been under general observation at Karner 

 for several years, where it was present in considerable numbers on some 

 trees. The species may be easily recognized by the peculiar, whitish 

 masses of pitch illustrated on plate 20, figure 2. They hang from the 

 underside of limbs and occasionally occur in numbers on the central stem. 

 During warm weather drops of pitch may fall at times from the masses. 



Life history. The eggs of this species have been observed by Miss 

 Lida S. Eckel, who states that they are bright orange and arranged 

 regularly, projecting radially about the equator of the spherical pitch drop. 

 She states that in the case of specimens under observation, eggs were 

 deposited only on fresh pitch and never on old, hardened lumps or on 

 twigs or leaves. No new masses of pitch appeared on the stems, as would 

 have been the case had the insect punctured the bark for the purpose 

 of starting an e.xudation. She therefore concludes that this insect takes 

 advantage of fresh pitch masses, and as a rule there are plenty of them 

 occurring under normal conditions. She states that the young larvae
