New Zealand and Fiji. The first paper is siippletnentary to the au- 

 thor's book on the Scale Insects of New Zealand, and comprises de- 

 scriptions of new species and notes on those formerly described or on 

 introduced species, among which is mentioned Mytilaspis citricola Pack., 

 which was found on oranges received from Fiji. Six plates illustrate 

 this paper. Four new Psyllidse are described in the second paper, 

 which is illustrated by three plates, and in the third six new species of 

 Aleurodes, with one plate. 



We regret to notice the confusion which Mr. Maskell has introduced 

 into the now well-settled matter of arbitrary terminations for the higher 

 groups and his abandonment of the accepted names " sub family " and 

 " tribe," for the extremely indefinite terms " group " and "subdivision." 

 Be also and quite unaccountably calls the Coccidfe " Coccididie." He 

 has apparently adopted the plan of giving each of his group (subfam- 

 ily) names the termination " idinse" regardless of the declension of the 

 noun from which it was derived. This would not be noticed in the case 

 of " DiaspidinsB," which has hitherto been incorrectly written " Dia- 

 spinte," but it becomes an absurdity in the case of " Lecanidiuse" and 

 " Coccidinse." Worse still is his use of the universally accepted family 

 termination "idoe"for his "subdivisions" (tribes), bringing about such 

 names as " Lecanidae" and "Acanthococcidse," which in his own signifi- 

 cation have only tribal value. There is no danger that anyone will 

 follow Mr. Maskell in such eccentricities, and we call attention to them 

 simply to obviate a possible misconstruction of any of his shorter writ- 

 ings in which these terms may be used. 



Professor Harvey's Bulletin on the Apple Maggot."— One of the best pieces 

 of work which has been done by the experiment station entomolo- 

 gists in the past year has resulted in the publication of this paper by 

 Professor Harvey. He has outlined a careful investigation and carried 

 it through successfully, and has presented his results in a straightfor- 

 ward, scientific, and readable way. He gives for the first time accurate 

 observations upon the eggs, careful studies of the reproductive system, 

 observations upon the act of oviposition, and a list of sixty-six varieties 

 of apples infested by the maggot, with comparative statements as to 

 damage. His summary of the life-history is very careful, and his con- 

 sideration of the remedies includes an account of the useless methods, 

 the preventive measures, and the direct methods. He follows with 

 some critical remarks upon the anatomy of Trypeta, and a summary of 

 the previous writings upon this insect, correcting the numerous errors
