286 THE ENTOMOLOGIST. 



of what is known of their life-histories, of their systematic posi- 

 tion and chissification, with criticisms on the latter, is given, 

 their external structure dealt with at some length, as well as 

 such topics as polymorphism of the organs of flight. The in- 

 troduction gives a general account of Koebele and Perkins's 

 expeditions to Australia, Viti, and the United States ; deals with 

 the most approved mode of handling beneficial insects, sum- 

 marizes the previous parts of the bulletin, and lists the parasites 

 and their hosts. 



The biology of certain " Neuroptera " has been discussed 

 recently, viz. that of the Embiidte by Friederichs (46), Termites 

 by Holmgren (48), and Dragonflies by Osburn (52). 



Buttel-Eeepen (47) deals with the Honey-bee, Ajjis mcUifica 

 (recte melUferal). First, there is a reprint of Gerstaecker's 

 scarce work on the geographical distribution and races of the 

 Honey-bee, published in 1862. The original home of the bee, 

 its biology, and that of its varieties and allies are then discussed 

 at considerable length. 



Perkins (49) briefly records his impressions of an entomo- 

 logical trip to Eastern Australia, and subsequently (50) makes 

 remarks on the typical PJiopalocera of Queensland. 



Doflein's (56) work deals with his travels in China, Japan, 

 and Ceylon, and is fully illustrated. It is of a general character, 

 treating of anthropology, zoology, botany, pisciculture, and so 

 forth. But, in the last three chapters especially, there are many 

 notices on insects — birds hunting butterflies, mimicry, butter- 

 flies' sense-organs, termites (a whole chapter being devoted to 

 these^ ants, and coccids. 



Van Dine (51) discusses in detail the mouth-parts of the 

 Tenthredinidae, illustrating his studies by two excellent plates. 



Pawlowsky (55) has published an account of his studies on 

 the mouth-j^arts of fleas. 



Distant's Catalogue of the Cicadidas of the World (54) sup- 

 plies a long-felt want, though it is a pity it was not issued as a 

 part of Lethierry and Severin's well-known series. It would 

 also have been better to give the geographical distribution in 

 greater detail. As is often the case with this author, accuracy 

 of dates seems a minor matter. The work is more than a mere 

 list, as analytical tables of the genera in each " division " are 

 provided, and the larger genera are divided into sections of 

 which the characters are stated ; a synopsis of the divisions 

 themselves would have been useful, as one has now to refer to 

 two volumes of a magazine to compare the several divisional 

 diagnoses. Amyot's monouymics, accepted by Distant, have no 

 place in binomial nomenclature. They were " species," and 

 avowedly proposed to replace the Linnean method. Cicadetta, 

 Kolenati, should then replace Melavqjsalta, Kol., and the other 

 " names " of Amyot, attributed to Kolenati.
