ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 53 



Genital Apparatus of Trichoptera.* — H. Stitz supplements the 

 work of Zander on the male genital organs of Trichoptera in a few 

 points, and reviews the conditions in the female of Limnophilus Mpunc- 

 tatus, Phryganea striata, and Molanna angustata. From these he con- 

 cludes that all the parts of the female genital apparatus of the Micro- 

 lepidoptera are found in the Trichoptera, but in other positions and 

 variously modified. The Trichoptera in the structure of these organs 

 approach the Neuroptera. 



Studies on Lice.f — Giinther Enderlein gives a description of the 

 external structure of lice. He shows that the Anoplura must remain as 

 one of the five sub-orders of Rhynchota. Four families are recognised 

 • — Pediculidas, Hsematopinidas, Echinophthiriidge, and Haematomyzidse. 

 An analytic key to the families, sub-families, and genera is supplied, and 

 four new genera are described. Finally, the author has some remarks to 

 make on the systematic arrangement of the orders of Insecta. 



Dermatobia hominis.f — H. B. Ward gives a full account of the 

 structure, development, and distribution of the larva of this cestrid 

 or bot-fly, which sometimes occurs as a parasite in man. It occurs 

 commonly in the skin of cattle, pigs, and dogs, less frequently in man, 

 rarely in the mule. It is also recorded from agouti, jaguar, various 

 monkeys, the toucan, and an ant-thrush. In some regions it is a 

 veritable plague to cattle. Its presence in man is accompanied with 

 excruciating pains, especially at times when the larva is moving. In no 

 case on record has the adult been developed from any larva taken from 

 human flesh. It occurs in Brazil, Colombia, Mexico, Costa Rica, 

 approaching close to the borders of the United States. 



3. Arachnida. 



Structure and Classification of Arachnida.§ — E. Ray Lankester 

 gives a reprint of his article on the Arachnida from the tenth edition 

 of the ' Encyclopaedia Britannica. 1 



Tick Fever in Uganda. || — P. H. Ross and A. D. Milne give some 

 notes on fever cases due to tick-bite, which seems to transfer a spirillum 

 to the blood. The tick has been identified by F. V. Theobald as 

 Omithodorus savignyi (Audouin) var. cceca Neumann, supposed by 

 some to be the same as Argas moubata (Murray). Their habitat is in 

 the old and dirty thatch of native huts, in cracks of mud walls and 

 floors, in which they hide during the day, coining out to feed at night. 



Oribatid Mites from the Neighbourhood of Cambridge. f — 

 < '. Warburton and N. D. F. Pearce give a list and note that in four 

 winter months specimens of forty-seven out of the hundred known 

 British species were taken in the neighbourhood of Cambridge, and 

 that every one of the fifteen British genera is locally represented.
