ZOOLOGY AND BOTANY, MICROSCOPY. ETC. 301 



Neocuterehra, type species N. squamosa. This form exhibits resem- 

 blances to the pm-ely neotropical (Estridfe-Cuterebrinas and to the 

 Muscidse, but without a knowledge of the imago the systematic position 

 is uncertain. 



Some interesting cases of the occurrence of CEstrid larvte in un- 

 usual situations and hosts are discussed. These have been observed 

 most frequently in beasts of prey, e.g. the case of the larva of Oestrus 

 ovis in the stomach of a lion. 



G-reen Pig-ment of Locustids.* — P. Podiapolsky finds that the green 

 pigment of Locusta viridissima can be split into a yellow and a green 

 component, as vegetable chlorophyll can be split into xanthophyll and 

 chlorophyllin. The spectroscopic characters are closely similar, but this 

 does not, of course, prove chemical identity. An ammoniacal solution 

 of cochineal shows the same two absorption-bands between D and E as 

 an aqueous solution of oxygenated blood. The position of the green 

 pigment along the trachete in the wings is interesting. Is it chlorophyll 

 which the insect gets from its food and deposits, like a fat, peripherally ? 

 Or is it a quite different pigment which the insect manufactures for 

 itself ? 



Enemies of the Olive.t — A. Berlese and his collaborateurs at the 

 Entomological Station at Florence have made a scientific and practical 

 study of some of the insects infesting the olive, especially the olive-fly, 

 Dacus olecB. The studies refer to many other insects, and give valuable 

 suggestions as to counteractive measures. 



Italian Scale Insects. — G. Leonard! | describes a number of new 

 forms, including Micrococcus and Macrocerococcus, as new genera of 

 Dactylopiinge. He also discusses§ Aonidiella aurantU (Mask.) a scale- 

 insect of the orange, new to Italy. In another paper he describes 

 Faleococcus pulcher, Lecamdiaspis haculifera, Aulacaspis penzigi, and 

 other new species collected byO. Penzigi from the island of Giava. The 

 illustrations in these papers are of great excellence. 



New Copeog'nathi.lf — Costantino Piibaga describes two new Psocidae 

 from Tuscany — Dorypteryx albicans Rib. sp. n., a representative of a 

 genus hitherto known only by an American species, D. pallida (also 

 reported from Germany), and Myopsocus eatoni MacLachl. var. europceus 

 Rib. (var. n.). 



Sub-division of Genus Aphis.** — G. del Guercio proposes to sub- 

 divide the genus Aphis into four genera — Anuraphis, with. Aphis 2)yri 

 Koch as type ; Aphis L., with Aphis samhuci L. as type ; Uraphis, with 

 Aphis genistce Kalt. as type ; and Microsiphon, with Aphis tormentillce 

 Pass, as type.
