Although the parasite, Trichogyamma minntiim, was extremely 

 abundant during 1919 in eastern Massachusetts, subsequent observa- 

 tions show that its occurrence is too erratic for it to be reUed upon as 

 a permanent check on the borer. Parasites are now being introduced 

 from France, and it is hoped that they will prove of considerable service, 

 though the results may not be apparent immediately. 



The preventive and remedial measures recommended have already 

 been noticed [R.A.E., A, x, 211].

 Psyche, Boston, Mass, xxix, no. 3, June 1922, pp. 92-94. 



The Anobiid, Caenocara oculata, Sa}', has been observed in New 

 Jersey breeding in the puffball. Scleroderma vulgare. On 5th September 

 several adults were found projecting from small circular holes in the 

 walls of the fungus, and in it numerous full-grown larvae were found, 

 some of which had constructed oval cells in the spore mass. The larvae 

 undoubtedly feed chiefly when the fungus is young and the interior is 

 sohd and fleshy. The larva, pupa and adult are described.
