tions and the Empidae presented by Mr. Ilamm, and labelling 

 as well as printing for the accessions to the British Collections 

 presented by Col. Yerbury, Mr. H. Donisthorpe, and Mr. F. C. 

 VVoodforde. 



A large piece of work which was taken up again and 

 again in the intervals between others was the labelling of 

 the Baden-Sommer Collection containing nearly 50,000 

 Colcoptcra. 



5. Work on the Collections of Orthoftera. 



Mr. Shelford's illness compelled him to give up the post 

 of Assistant Curator at the end of 191 1. It is greatly to be 

 regretted that his fine work upon the Hope Collections of 

 Orthoptera has thus come to an end. It is very much to be 

 hoped that at some future time he may be able with recovered 

 health to revisit the Department, and again study the collec- 

 tions which he has done so much to increase and bring into 

 their present excellent condition. In spite of his illness and 

 absence from Oxford, Mr. Shelford was able to do work of 

 great value to the Department by looking over and correcting 

 a long series of tables, and by cataloguing accessions. The 

 titles of papers published by him in 191 1 appear on p. 97.N. 



6. Work on the Collection of Picrinac. 



1 >r. F. A. Dixey has been occupied in extending his in- 

 vestigations on the subject of the scent-distributing apparatus 

 in Lcpidoptera. These formed the subject of a Friday evening 

 Discourse at the Royal Institution of Great Britain, and of 

 a paper and demonstration at the meeting of the British 

 Association at Portsmouth. He has also worked out the 

 Pierinae in several interesting collections, including one from 

 the Mediterranean Sub-region (P. de la Garde), and others 

 from Nigeria (J. J. Simpson), German East Africa (Entomo- 

 logical Research Committee), and Australia (G. A. Water- 

 house). The latter included authentic specimens of the rare 

 Pierine Taehyris mclania, which since its description by 

 Fabricius in 1 775 has been almost unknown to entomologists. 

 These were exhibited at a meeting of the Entomological
