eyes, but the brain proper is not larger than that of the worker. The 

 author has devoted much attention to the two "mushroom-shaped bodies" 

 — parts of the brain— which reach their climax in Hymenoptera. They 

 seem to be organs for the combination of various sensory impressions, 

 and probably for the acquired associations. 



Parasitic Hymenoptera from the Tertiary of Florissant.* — C. T. 

 Brues describes no fewer than 112 clearly defined species of fossil Hymen- 

 opterous insects from Florissant, Colorado. The wings are usually well 

 preserved, lying between the laminse of the shale, and the preservation 

 of the colour is often remarkable. Most of the species are Ichneumon- 

 idre, but Chalcidoidea and Braconidre are well represented. 



Viviparity in Phorocera serriventris and other Flies.f — W. Wesche 

 notes that this Tachinid fly is viviparous, the living larvae being intro- 

 duced by the " ovipositor " into caterpillars. By means of the Microscope 

 it is possible to detect the viviparous condition of flies, if the specimens 

 are properly cleaned and prepared, as the hard chitinous jaws of the 

 larva? are not dissolved by potash, and are seen through the cleared 

 plates. Wesche has observed this not only in Phorocera serriventris, but 

 in Oliviera lateralis F., Plagia trepida Mg., Phoraruficomis Mg., Myiobia 

 fenestrata Mg., Siphona geniculata Deg., Blepharidea vulgaris Fin. 



Gossyparia ulmi on Mistletoe. J — L. Fulmek found on the mistle- 

 toe (in Wachau) full-grown females of the Coccid Gossyparia ulmi, which 

 is usually found on elm-trees. 



Tobacco Beetles. § — J. P. Wright has a note on beetles from Turkish 

 tobacco-leaf, which apparently " thrive " in napthalin. Bisulphide of 

 carbon effectually disposes of them. 



Palaearctic Spongostylinae.|| — P. Sack gives an account of this 

 family of Bombyliida3, which includes a number of sun-loving forms, 

 with a tuft of hair at the tip of the antennas, such as Anthrax virgo 

 Egger, Bibio hesperus Rossi, and Spongostyliim mystaceum Macq. The 

 author makes eight new genera. 



Odoriferous Organs in Female Lepidoptera.1T — H. H. Freiling de- 

 scribes (1) odoriferous organs on the wings of both sexes in Adopsea 

 lineola, Aciptilia pentadactijla, Notris verbascella ; (2) sensory organs on 

 the wings of N. verbascella ; (3) odoriferous organs (modified scales or 

 setas) near the external genital organs in females of Gonopteryx rhamni 

 and Euplcea asela, Stilpnotia salicis, and Thaumatopcca pinivora ; (4) in- 

 tegumentary duplicatures between the 8th and 9th abdominal segment, 

 modified as odoriferous structures — a dorsal fold in the female of Orgyia 

 antiqua and lateral saccules in the female of Bombyx mori ; and (f>) 

 evaginable odoriferous brushes lying dorsally between the 7th and Kth 

 segments in the males of Euplcea asela and Danais septentrionalis.
