that an error has been made in confusing the species of the true 

 genera Diaspis and Aulacaspis, since the arrangement of the 

 dorsal tubular spinnerets in the female has been used as the strik- 

 ing character with these and some allied genera, rather than the 

 more important structural characteristics of the anal plates. 

 Some day I fear there will be a general untwisting of Mr. New- 

 stead's assignment of the species of this genera. 



An important contribution to the literature of the much-dis- 

 cussed male of Lecanium hesperidum occurs in volume ii, and 

 Mr. Newstead describes the second stage and the puparium of 

 what is undoubtedly the true male of this species. He indicates 

 that the male, as was quite to be expected, belongs to the true 

 Lecanium type, and that the alleged discovery by Moniez had 

 probably reference to one of the Chalcidid parasites which uni- 

 versally infest females of this species. 



The many illustrations, and especially those upon the plates, 

 all done by Mr. Newstead himself, are better done than any 

 figures of Coccidae which have heretofore been published. 



The revised nomenclature of the Coccidse, as displayed by Mrs. 

 Fernald in her Catalogue of the Coccidse of the World, and which 

 must probably be accepted, is not followed in the text proper, but 

 in an appendix to volume ii it receives proper recognition.

12. Catalogue of the Lepidoptera Phalcence in the British 

 Museum, Vol. IV. Catalogue of the Noctuidae; by Sir George 

 F. Hampson. Pp. xx, 689, with an accompanying part contain- 

 ing plates lv-lxxvii. London, 1903. — The issue of Part IV of the 

 British Museum Catalogue of Moths will be welcomed by all 

 interested in this subject. It contains descriptions of some 1200 

 species of the Agrotinse, the first of the fifteen sub-families of the 

 Noctuidse. The plates, reproduced by trichromatic photography, 

 are very beautiful and show the perfection to which the process 

 has been brought. 



13. General Zoology ; by C. W. Dodge. 482 pp., 379 figs. 

 (American Book Company.) — Professor Dodge has revised and 

 re-arranged " Orton's Comparative Zoology " in a way which is 

 highly satisfactory to the teacher and to the general student.

1. American Association. — The fifty-third meeting of the 

 American Association for the Advancement of Science was held 

 at St. Louis during the week from December 26, 1903, to January 

 1, 1904. Dr. Carroll D. Wright was President of the meetings 

 The address of the retiring president, Dr. Ira Remsen, was 

 delivered on December 28th, on the subject " Scientific Investiga- 

 tion and Progress." This address is given in the issue of Science 

 for January 1 and the following numbers of the same periodical 

 give a full account of the proceedings. Affiliated societies to 

 the number of twenty-one held meetings in conjunction with the
