Male Terminal Segments and Armatures in the Hymenopterous 

 Genus Colletes.* — F. D. Morice, with a view to rendering the recogni- 

 tion of species of this genus easier, has constructed a table of the 

 copulatory armatures which yield remarkable specific characters. Notes 

 are given on thirty-five species, and their armatures figured. 



Natural History, Anatomy, and Physiology of the Honey-Bee.f 

 T. W. Cowan, in response to a call for a new edition of his hand-book 

 on the Honey-bee, has issued one revised and corrected, upon which 

 " no expense has been spared to make it the most perfect on the subject 

 of which it treats." The work contains chapters on partheno- 

 genesis, metamorphosis, and hermaphrodite bees, in addition to those on 

 anatomy and physiology, of which there are twenty-one. 



Australian Lepidoptera.J — A. J. Turner, in a much-needed revision 

 of the Geometrida?, sub-family Hydriomenina?, has increased the number 

 of recognised species by one-half. The work is so tabulated that by 

 means of it species can be worked out, and is of value on this account. 



The Endoderm of Lepidoptera.§ — F. Schwangart has investigated 

 a number of developmental points in connection with the endoderm, 

 and has made out, inter alia, that the gland structures of the gut arise 

 out of parts of the lower layer of the fore- and hind-gut, which are 

 pushed downwards with the blind ends of the stomo- and proctodamm. 

 In Endromis early separation of endoderm and mesoderm does not take 

 place. 



Aberrations of Lepidoptera.]] —Under this title P. I. Lathy de- 

 scribes and figures forty-five notable variations. Two examples may be 

 given. (1) A specimen of Melincea mauensis from Demerara, which is 

 gynandromorphous, the left side being female and the right male. It is 

 not definitely stated whether the note refers to external features only or 

 not. (2) A male of Amathnsia andamanensis, with three ocelli on the 

 hind wings below. 



Mosquitoes of Para.f — Emilio A. Goeldi has made a number of 

 experiments on the mosquitoes of this region, with especial reference to 

 Stegomyia fasciata and Culex fatigans, which appear to have considerable 

 hygienic importance. 



Reduction of the Head in Dipterous larvae.** — N. Holmgren gives 

 comparative notes, with homologies, on the head-parts of the larvse of 

 Chironomus, Phalacrocera, Microdon, and Musca. One point dwelt upon 

 is the relation of the T columns seen in a cross-section of the mouth- 

 cavity of Musca, with cavities in the two-layered cuticula of the mouth of 

 Phalacrocera, which are lined with a chitinous layer, and which though 

 different in appearance are shown to be the same structure.
