find a new locality about twelve miles from the original one, where I took several 

 ? . At Wootton it forms its burrow in decaying stumps, in the new place in a 

 stiff clay soil ; interruptus, De Geer — I found only one $ of this uncommon species. 



Odynerus pictus, Curt., was not very common, and antilope, Panz., even less so. 



Many scarce species of the Anthophila were found. Among the AndrenidcB : 

 Prosopis coiifusa,l^y\., was not rare on bramble blossoms in woods; brevicornis, 

 Nyl., was less common, but was also found at Sidmouth, where I also toot the J of 

 P. pictipes, Nyl. 



Nearly all the species of the genus Sphecodes were taken, including S. puncti- 

 ceps, Thorns., at Sidmouth ; S. ferruginatus, Thoms., which occurred here in 

 thousands and tens of thousands. In several places, where patches of Carduus 

 arvensis grew, they could have been boxed in innumerable quantities after sundown 

 on warm evenings, five or six specimens being found on every blossom. The $ I 

 took at Oxford in the spring. S. hyalinatus,^h.ovas., not quite so plentiful, but very 

 abundant on the same thistle flowers. I took several females of this species at 

 Oxford. S. variegatus, Yon Hag., with the preceding, but far less plentiful ; I could 

 only secure about two dozen. S. dimidiatus, Von Hag., fairly common at Oxford, 

 but of course I only took the hibernated females. S. affinis, Von Hag., more or less 

 common in both places. 



Andrena, Fab., was very well represented : Sattorfiana, Fab., 1 S and 5 ? on 

 flowers of the common Scabious at Sidmouth ; Cetii, Schr., 1 $ and 1 $ on the 

 same flowers in the same place ; pilipes, Fab., was common at Sidmouth on bramble 

 blossoms : roscB, Panz., was not plentiful there, on the same flowers ; tlioracica, Fab., 

 swarmed on nearly every flower, thistle, bramble, crepis, fleabane, and many others ; 

 angustior, Kirb., I took 1 S and H ? of this rare species at Oxford, all the females 

 had their legs covered with pollen, and occurred solely on the common buttercup ; 

 hicolor, Fab., is a common species, it is very partial to mallow blossoms and Crepis ; 

 varians, Rossi, helvola, Linn. — the $ of the former and ? of the latter were taken 

 at Oxford ; fucata, Sm., 5 ? at Oxford, all on whitethorn blossom ; simillima, Sm., 

 2 (? and 8 or 9 $ at Sidmouth. These were chiefly taken on Carduus arvensis, but 

 also on Inula and other flowers ; denticulata, Kirb., both sexes at Sidmouth, but not 

 very plentifully ; chrysosceles, Kirb., in countless numbers in the spring, and abundant 

 at Oxford ; hnmilis, Imh., very locally at Oxford, but abundant in one place ; dorsata, 

 Kirb., 2 ? at Sidmouth on bramble blossoms ; Wilkella, Kirb., at Oxford, very 

 locally. 



Cilissa koemorrhoidalis, Fab. — the males of this species were very abundant 

 when I left for Sidmouth, but I only took 8 ? ; on my return they were past. It is 

 not at all confined to the harebell ; in the woods and on the hills it is found on the 

 three species of mallow, the harebell, and the Canterbury bell ; in lanes abundantly 

 on Geranium Rohertianum, in company with Andrena bicolor, Fab., Chelostoma 

 campanularimi, Kirb., &c. It is much preyed upon by a spider which infests these 

 flowers, and which rushes out and strangles it as it alights. 



Of the ApidcB, both species of Fanurgus occurred at Sidmouth. I took a single 

 $ of Nomada ochrostoma, Kirb., here, at Oxford it was not rare ; in both places it 

 was parasitic on Andrena Afzeliella, Kirb., not on A. labialis, Kirb. N. obtusifrons, 

 Nyl., 2 $ at Sidmouth, one on Senecio and the other on Carduus. N.ferruginata,
