volume form is received by an institution, the cards relating 

 to one or more taxonomic groups, or to one or more topics as 

 physiology or anatomy, are often of great aid to an individual 

 working therein. 



The book form is furnished both by the Zoological Record 

 and the Bibliographica Zoologica of the Concilium. Opinions 

 doubtless vary as to which of these is more conveniently 

 arranged. Both necessarily include many cross-references and 

 their usefulness is measured, to a great degree, by the com- 

 pleteness of these. This also applies to the cards. No great 

 research is required to discover, even in the latest issues of 

 all three series, that the cross-references are by no means 

 complete and that dependence on them will not furnish the 

 reader with all the references on a given subject that each 

 volume or set of cards contains. 



It is a great pity that two distinct organizations exist for 

 the same purpose and it would seem to be true economy, 

 especially in these days, for the two bodies to combine their 

 labors for the greatest benefit of workers in all branches of 

 Zoology and, united or co-operating, continue to issue volumes 

 (annually or oftener) and cards, to suit the different needs 

 of institutions and individuals. Happily, we understand, 

 negotiations with such an end in view are under way. But 

 whatever may be their outcome, financial support from all 

 using these bibliographies is an absolute necessity and we can 

 not urge too strongly the duty of all Zoologists (including* 

 entomologists) to sustain and strengthen these publications.

Aphis-Lion Attacking Man (Neur., Chrysopidae). 



The following observation may he of interest as a case of a preda- 

 ceous insect attacking man without provocation. 



With the exception of such insects which, like mosquitoes and blood- 

 sucking flies, depend upon blood as food, insects will not generally 

 attack man unless taken in the fingers or perhaps entangled in the
