a single spray will largely depend. Previous experimenters 

 have insisted on the necessity of spraying for the second brood 

 if wormy orchards are near. We believe, however, that nor- 

 mally the codling moth breeds generation after generation in 

 a most restricted area, that it may even be said to have a home- 

 tree. If, therefore, all the worms in an orchard be extermin- 

 ated, the chance for outside re-infection under ordinary con- 

 ditions is small. 



In the evolution of this fight against the codling moth, band- 

 ing was first thought of. Then this was supplemented by 

 spraying. The spraying became of most importance, and in 

 time supplanted banding. In the development of spraying 

 methods, the misty concentrated spray of the hand pump was 

 replaced by high-pressure spraying, and the number of hap- 

 hazard sprayings was continually cut down, until to-day we 

 believe that a single spraying can be made completely effective 

 if thorough and on time, the maximum saving at the minimum 

 cost. Through the study of a few decades economic entomol- 

 ogy has enabled the farmer to save his entire crop instead of 

 losing all, an unselfish investigation that has added an un- 

 tellable measure to the world's good. 



I WOULD be glad to get material in the Noctuid genus Hoinoptcra 

 and its allies from all parts of the country for study in the prepara- 

 tion of a revision of this series. I will name and return specimens 

 promptly, for the privilege of retaining such as may be needed in 

 completing the work. JOHN B. SMITH, New Brunswick, X. J. 



TELEA POLYPHEMUS. This moth is quite common in California. The 

 preferred food plant appears to be the Live Oak (Quercus agrifolia), 

 a non-deciduous tree. For this reason it would be of little advantage 

 for the pupa to fall. The foliage of the Live Oak is dense and 

 detection of the cocoon is difficult. T have never known any other 

 than attached cocoons from this locality. I have found several which 

 were attached by a short silken pedicle similar to that of promctlica, 

 In one instance this stalk was about an inch and three quarters in 

 length. A similar case of such a specialization is described by Grote 

 in the Proceedings American Philosophical Society. Vol. XTI, 401, 1902. 

 Besides Quercus, the larva feeds on Rosa, Primus and others. Polyphe- 

 mus is badly parasitized here by ichneumonid, tachinid, and braconid 

 flies. KARL R. COOLIDGE.
