8. Work on the Collections of OrtJioptcra. 

 Owing to Mr. R. Shelford's protracted illness work on the 

 collections of Orthoptera was much interrupted. The arrange- 

 ment of the Phasmidae was completed and the collection now 

 occupies 90 drawers. The following sub-families of Locics- 

 tidae have been arranged : — Stenopelniatinae, Gryllacrinae, 

 Saginae, Callime/iinae, Ephippigei^inae, and Decticinae (in 

 part). Dr. A. Griffini, of the R. Istituto Tecnico, Bologna, 

 rendered the most generous and valuable assistance in de- 

 termining the Gryllacrinae. The bulk of the collection, 

 including some of Francis Walker's types, were sent to 

 Dr. Griffini, and three memoirs have issued from his pen as 

 a result of his study of these specimens. A small supple- 

 mentary collection of Tetriginae (Fam. Acridiidae) was sent 

 for determination to the well-known authority on this group, 

 Dr. J. L. Hancock, of Chicago, and will be further noticed in 

 next year's Report. The Blattidae collected by Drs. Michaelsen 

 and Hartmeyer in S.W. Australia, by Dr. Sheffield Neave in 

 the Congo basin, and the Blattidae, Mantidae and Phasmidae 

 collected by Dr. Rivet in Peru, were determined during the 

 course of the year and co-types of most of the new species and 

 many much-desired duplicates of known species have been 

 deposited in the Hope Collections. By far the most important 

 accession during the year is the Van der Poll collection of 

 Orthoptera, purchased from Mr. O. E. Janson, and presented 

 by the Professor. This collection comprised a great number 

 of Phasmidae, and the incorporation of these specimens in 

 the Hope Museum series occupied most of the autumn 

 months. Owing to this valuable addition the Hope Collection 

 of Phasmidae is now one of the largest in Europe, and 

 certainly one of the most important, containing as it does so 

 many of Westwood's types, all of H. W. Bates's types, and 

 a few of Serville's and Gray's. The Van der Poll collection 

 also included a fine series of Locustidae, which still await 

 incorporation, many fine Mantidae, and a few Blattidae and 

 Acridiidae. The memoirs on the family Blattidae and other 

 Orthoptera, published during the course of the year 19099 

 will be found in Section 14 (pp. 11-15).
