abandoned entomology in favour of sightseeing. On the 16th, how- 

 ever, we crossed the Sea of Marmora for two more days on Asiatic 

 soil at Broussa, a health-resort among the hills of Anatolia, under the 

 Bithynian Olympus. Here we used our nets and bottles for the last 

 time. A few of the Lebanon insects re-appeared, but on the whole 

 both fauna and flora seemed European rather than Oriental in 

 character, and almost commonplace after our more exciting experi- 

 ences in the regions we had left behind. 



A complete list of our captures would be a long one, and may 

 probably never be compiled. Even of my own I am still quite unable 

 to offer one, many species being still unidentified. I may mention, 

 however, that all my bees, and some of Dr. Schmiedeknecht's, have 

 been examined by Herr Friese, and that he has already described 

 some fifty new species from among them. I have also several new 

 Chrysids, which M. du Buysson will shortly publish. The Diploptera 

 and the few Sphegidce in my cartons I am slowly working out myself, 

 and I am pretty sure that there are novelties in both. Only of Saw- 

 flies I seem to have taken nothing that was not known already. 



This, for a tour of eighty days, on many of which collecting was 

 impossible, is I think a pretty satisfactory record.

ODYNERUS T03IENT0SUS, Thoms., A SPECIES NEW TO BRITAIN, 



AND SOME REMAEKS ON THE WALCOTT COLLECTION 



OP ACULEATE HYMENOPTERA. 



BY R. C. L. PERKINS, B.A. 



I have recently carefully exami]icd the Walcott collection of 

 British Aculeata, which was presented to the University Museum at 

 Cambridge after the death of the collector. "Walcott, as is well 

 known, collected chiefly in the neighbourhood of Bristol, but unfor- 

 tunately very few of the specimens bear any note of locality, which 

 largely decreases the value of his collection. Some spticimens are 

 ticketed with the date of capture only, and Walcott appears to have 

 been particularly active from 1S39 — 1842. The earliest date observed 

 by me is September, 1838, when he captured a female of the rare, 

 fossor, Didineis lunicornis. It is clear, therefore, that a large part of 

 the collection was made more than half a century ago; yet, in spite of 

 this, so admirably has it been preserved that for the most part the 

 specimens appear as fresh and bright as if they had been quite
