983 



Over 90 genera and 525 species are treated. 

 Only about 15 species occur in the United 

 States, althougli several described by Say are 

 unknov^n to the author. The Malay archipel- 

 ago and Madagascar are especially rich in 

 large and curious forms. The article is illus- 

 trated by nine plates. 



Professor F. Meunier has given us another 

 article on the dipterous fauna of the amber.* 

 He describes species of Tabanidte, Xylopha- 

 gidte, Leptidfe and Empidaa. But what is 

 perhaps of most interest is a diopsid, Bphyra- 

 cephala hreviata, very similar to the one spe- 

 cies occurring in the eastern United States. 



Mr. E. Shelford has published an interesting 

 article on insect mimicry in the Malay region.f 

 There is a systematic arrangement of the cases 

 of Batesian mimicry according to the natural 

 orders, details being given in each ease. This 

 is followed by a chapter on convergent groups. 

 Several Miillerian associations are represented, 

 particularly the lycoid, coccinellid, and that of 

 melipona. There is an appendix with descrip- 

 tions of the new species by various specialists. 

 It is illustrated by five colored plates. The 

 cases figured, as well as those figured by Mar- 

 shall from South Africa, are no more strik- 

 ing than can be found in the insects of our 

 own country. 



The Anales Sociedad Espanola de Historia 

 Natural, Vol. XXX., 1902, contains several 

 entomological articles. Uhagon completes his 

 revision of the Malachidse of Spain; M. Me- 

 dina y Ramos gives a sjmopsis of the Spanish- 

 Chrysididse (101 in number) ; and A. Martinez 

 y Fernandez-Castillo gives a revision of the 

 group Calopteni of the grasshoppers, treating 

 the known forms of the world; none of which, 

 however, occurs in the United States. 



An increase in entomological activity in 

 South America is indicated by Volume V. of 

 the Eevista Museu do Paulista (Sao Paulo, 

 Brazil, 1902), which contains three large 

 papers on insects. One of two hundred pages

with fine plates is by H. W. Broleman on the 

 myriapoda of the Museum of Sao Paulo. 

 Another is descriptive of the solitary bees of 

 Brazil. It is by 0. Schrottky, synoptic in 

 form, illustrated by two plates, and contains 

 notes on the habits of some species. The 

 third article is by J. G. Foetterle on new 

 Brazilian lepidoptera, illustrated by four 

 handsomely colored plates, and describes 

 fourteen species. 



Dr. L. Sander has published a long account 

 of locust invasions of the German colonies in 

 Africa.* The laigratorial African grasshop- 

 pers are species of Pachytylus and Schisto- 

 cerca, the latter similar to those of South 

 America. The author gives an historical ac- 

 count of the ravages of locusts, followed by 

 chapters on structure and life-history. He 

 considers the causes and extension of the mi- 

 grations, and the various natural enemies, 

 especially birds, that prey upon the pests. A 

 large part of the book treats of remedies, 

 chiefly a history of what has been done in 

 other countries, much attention being given 

 to American methods. An appendix contains 

 an old German edict against grasshoppers. 



M. Neveu-Lemaire has devised a new classi- 

 fication of the Gulicidse.f After an historical 

 review he criticizes the classification of Theo- 

 bald, and proposes his new arrangement based 

 on mouth parts and venation. He divides the 

 family into four subfamilies : Anophelinse 

 (including only Anopheles), Megarhininse (two 

 genera) ; Culicinse (with eight genera) ; and 

 Aedeinse (with six genera). He indicates the 

 type species of each genus.

THE HARPSWELL LABORATORY. 



The Editor of Science asks an account of 

 the Harpswell Laboratory. It is easy to com- 

 ply, for this biological station is one of the 

 most unpretentious structures one could im- 

 agine, as will readily be understood when it 

 is said that the whole plant — land, building
