tion) ; Brussels Museum (Dr. Sheffield Neave Collection) ; 

 Mus^e Royal du Congo, Brussels ; Senckenberg Museum, 

 Frankfurt-on-Main ; St. Petersburg Museum ; South African 

 Museum. A monograph on the Blattidae of the World is 

 now in course of preparation, and promises to be a work 

 of some years ; this family of insects has been much neglected 

 by entomologists during the past ten or twelve years, and 

 the number of undescribed or imperfectly known species is 

 considerable. 



The arrangement of the collection of PJiasmidae is now 

 completed ; the insects occupy 1 15 drawers and are repre- 

 sented by 1,498 specimens belonging to 168 genera and 510 

 species; there are 186 types, and 50 species appear to be new 

 to Science. Professor Westwood devoted special attention to 

 this family of Orthoptera, and published a classic memoir 

 on them. H. W. Bates also described the new species con- 

 tained in the Wilson Saunders Collection. On account of 

 its richness in type-specimens of Westwood and Bates, the 

 Hope Collection of PJiasmidae is the most important one \\\ 

 the country. 



A list of the PJiasmidae of the Godman-Salvin Collection 

 was drawn up for publication in the Biologia Centrali- Ameri- 

 cana, and the duplicates which were kindly presented by Dr. 

 F. D. Godman, Hon. D.C.L., F.R.S., filled some important 

 blanks in our cabinets. Dr. J. L. Hancock of Chicago again 

 kindly determined a collection of Tetriginae [Acridiidac), and 

 published a memoir on the results of his study ; the collection 

 was not very large, but it included no less than 11 new genera 

 and 37 new species. 



The arrangement of the Locustidae was commenced, but 

 a report on this collection is deferred until next year, when 

 it is hoped the work on it will be completed. 



5. Work on tJie Collection of Pierinae. 



Dr. F. A. Dixey continued his work on the Pierinae, paying 

 especial attention to the difficult genus Pinacopteryx, many- 

 remarkable forms of which have reached the Hope Collection 

 from Rev. K. St. A. Rogers, Mr. Neave, and Mr. Wiggins.
