 on the eggs ; a Pentatomid'.bug, Halyoniorphal picus, ¥., appearing 

 in May and June ; ants, which are occasional enemies ; a wasp, 

 Polistes hebraeus, F. ; an undetermined Ixodid tick ; and a Nematode.

 Plants.) — Byochugai Zasslii {Journal of Plant Protection), Tokyo, 

 vi, no. 2, 5th February 1919, pp. 1-5. 

 In a previous paper (Special Report of the Imperial Agricultural 

 Experiment Station, No. 19.) the author has disputed the existence 

 of the varieties of Aspidiotus perniciosus, Comst., established by 

 Oockerell, viz. var. andromelas, Ckll., and alhopiinciatus, Ckll. In 

 this article he makes further additions to the food-plants of this scale 

 and confirms the fact that the original San Jose scale infesting apple 

 may migrate to Citrus {Poncirus) irifoliafa, while the var. alhopunctatus, 

 which was said to infest only Citrus, migrates to the pear.

 Tortricodes fragariana, sp. n., is described from Victoria, British

 of strawberries ; and Aristofeli-afragariae, sp. n., the so-called " straw- 

 berry crown borer " from the same habitat, a species on which there
