 Entomology of Chili. The genus Icerya.] — Anales Zool. Aplicada,

The only known Chihan representative of the genus Icerya is Icerya 

 palmeri, which attacks Acaena argentea, the grape vine, lucerne and 

 other plants. 



Auftreten und Bek&mpfung der Reblaus im Kanton ZUrich 1913-1915.

 feU, XXV, no. 17, 28th August 1916, pp. 270-271. 



The data in this paper are taken from the last report of the Ziirich 

 Phylloxera Commissioner. In the period 1913-1915, 109 areas with 

 448 infested stocks were found, additional to the previous infestation 

 [see this Review, Ser. A, ii, p. 127]. About half of the new infestation 

 was found in 1915, a year in which carbon bisulphide was not procurable, 

 so that petroleum had to be used instead. Up to the time of writing, 

 this treatment seemed to have been successful. No flavour of petro- 

 leum was communicated to the grape juice. The area planted with 

 vines was 13,797 acres in 1881 and only 6,002 in 1914. 



Malenotti (E.). Sulle pretese variety del " Chrysoniphalus 

 dictyospertni" (Morg.) Leon. [On the supposed varieties of 

 Chrysomphalus dictyospermi.] — Separate, dated 28th July 1916, 

 from Redia, Florence, xii, no. 1, pp. 109-123, 6 figs. [Received 

 7th September 1916.] 



The author does not believe that true varieties exist among the 

 known forms of Chrysomphalus dictyospermi. This scale-insect infests 

 at least eighty different species of plants belonging to about twenty- 

 five widely dissimilar families in both tropical and temperate climates, 

 both greenhouse and outdoor plants being attacked, A marked 

 tendency to vary, together with the wide distribution and great range 

 of host plants of this species sufficiently explain the existence of a 

 multitude of local forms, which are insufficiently fixed to be treated as 

 distinct varieties,

Additional bamboo-infesting weevils are dealt ^vith in this paper 

 [see this Review, Ser. A, iii, pp. 306 and 696]. They include Rhinastus 

 pertusus, Dalm., on Chusquea gaudichaudii, Desmosotnus longipes, 

 Perty, and Astyage punctidata, sp. n., in the internodes of Merostachys 

 clausseni. 



The opinion is expressed that the weevil recorded by Bondar on 

 coconut and other palms in the State of Sao Paulo, as Amerrhinus 

 pantherimis, 01. [see this Review, Ser. A, iv, p. 220], is in reality A. ynca. 

 Sahib. Other Brazilian palms are infested by Homalonotus coriaceus, 

 Gyl., H. deplanatus. Sahib., and Acharias {Cholvs) parens, Fhs.
