98 HYMENOPTERA. 



sorial Hymenoptera ; the species he describes under the 

 name of Aj) or us belongs to a distinct genus, Evagethes of 

 St. Fargeau ; Ajjojms was captured in the vicinity of Ventnor ; 

 Tachytes unicolor occurred in the same locality : I have 

 hitherto considered this an extremely rare insect, Mr. Koth- 

 ney took seven specimens. One of the rarest species belong- 

 ing to the Pompilid(B, Agenia variegataj was taken at Steep 

 Hill near Ventnor. 



To the Hymenopterous Fauna of the Isle of Wight, pub- 

 lished in 1860, Mr. Rothney has added the species of Pom- 

 pilus already named and also JP. agilis ; of bees, the addi- 

 tions are, Andrena B.attorJiana, the finest of our indigenous 

 species ; A. tlioracica and A., pilipes. Megacldle argentatay 

 found at Ventnor, is an important addition ; also Nomada 

 armata, the parasite of Andrena Sattorjiana. 



No addition has been made to the FormicidcB, but one or 

 two captures of interest may be noticed: Mr. Lawson of 

 Scarborough took several specimens of Stenamma {3Iyr- 

 mica) Westwoodii in his own neighbourhood. On the first 

 of May I took the same insect in some numbers in nests of 

 the wood-ant, Formica rufa ; this species of Stenamma has 

 not been observed to construct its own nest, it appears to be 

 a constant guest-species. 



At Eastbourne, in the month of June, I observed a new 

 phase, new at least to myself, in the habit of Tetramorium 

 {Myrmica) ccesintum, I found numerous colonies under 

 stones; many of the channels of the nest were at that 

 time filled with pups of the males and females ; — this 

 species, according to my observations, usually constructs its 

 nest in sheltered situations, such as hollows in the ground 

 overhung with herbage, and small cavities in banks ', it is by 

 no means common. 



Tiphia Qninuta was found at Eastbourne near the Con-
