ZOOLOGY AND BOTANY, MICROSCOPV, ETC. 451 



New European and Mediterranean Cicadinse.* — S. Matsumura 

 notes that new species of beetles and butterflies are hardly to be found 

 in Europe, but there are still plenty of Cicadinse undiscovered. He 

 himself, during his stay in Europe and the Mediterranean region, has 

 found 90 new species, and he gives a description of about half of these 

 in the present communication. He found in Port Said and Egypt the 

 well-known Delp/iax furcifera, first described by Horvath from Japan, 

 and two other forms injurious to the rice crops in Japan and Formosa — 

 namely, Nephotettix apkalis Motsch. and Nisia nervosa Leth., were 

 found in Tangiers. 



Freezing Insect Larvse.t — James S. Hine subjected the larvse of a 

 moth, BeJJura obJiqua, which live in the stems of the cat-tail reed (Typha 

 latifolia), to six consecutive nights and days of freezing in water (the 

 temperatures varying from - 6° F. to - 16° F.). None of the specimens 

 shows signs of injury from the treatment. Three larvee treated similarly, 

 but without water, received no notable injury. He refers to other cases, 

 and points out that the susceptibility to cold is as marked in some types 

 as indifference to it in others. 



Odoriferous Gland of Cockroach. J — L. Bordas describes the large 

 arborescent gland found in the posterior part of the abdomen in male 

 cockroaches (Periplaneta orientalis and P. americana). It has been 

 erroneously regarded by some as an annex to the male genital system. 

 The whole of each of the component tubes is glandular. The secretory 

 cells are described, and it is noted that the defensive volatile secretion 

 is distinctly alkaline. 



Genitalia of Male Cockroach § — W. Wesche distinguishes the fol- 

 lowing parts : — (1) a tube for the passage of spermatozoa into the con- 

 taining apparatus, and a gland (Miall's conglobate) for the production of 

 some semi-viscid fluid, used in the formation of the spermatophore ; 

 (2) the combination of the theca and the hypophallus, penis, and 

 paraphalli, by movements of which the viscid secretion and the sper- 

 matozoa are brought together ; (3) the containing apparatus, with a 

 covering-plate held down over it by the apodeme. On excitement, the 

 lever would relax the muscles holding down the cover, and a fourth part 

 — the spinus — bending over would transfix a spermatophore and transfer 

 it to the cloaca of the female. The author compares the parts of the 

 complex mechanism with the similar structures in Diptera. 



Insects Injurious to Olives and Figs.|| — G-. Martelli discusses the 

 habits and life-history of the olive-fly (Dacus olece) ; F. Silvestri deals 

 with the number of generations in a year ; F. Silvestri, G-. Martelli, and 

 L. Masi have studied the Hymenoptera parasitic on the larva? of the 

 fly. F. Silvestri discusses Prays oleellus ; L. Masi deals with the various 

 parasites of Dacus olece; F. Silvestri describes Occophylhmbius neylectus
