58 HYMENOPTERA. 



dried-up droppings when I have observed Tiphia under 

 them, neither have I ever seen 2'iphia enter the holes down 

 which the larvse of Aphodius had burrowed when full fed 

 and about to undergo their change to the pupa state ; but I 

 have seen Tiphia just within the holes, and, having done so 

 on several occasions, I am led to think it highly probable 

 that it will some day be found that Tiphia is the parasite of 

 Aphodius. I am otherwise totally ignorant of its habits. 



I remarked that the specimens of Tiphia taken at Ilfra- 

 combe were uniformly much smaller than those taken at 

 Woolacombe ; this circumstance I believe to be attributable 

 to a more scanty supply of food ; probably at Woolacombe 

 the larvae had fed upon that of a large species of Aphodius, 

 those at Ilfracombe having been nourished upon a smaller 

 one. 



I have a species of ant to add to the British Formicidae ; 

 and when I call to mind that, limited as my opportunities of 

 research have been for some years past, yet notwithstanding I 

 have added Formica congerens and F. sanguinea, for in 

 old collections the latter species was represented by varieties 

 of F. rufa, the true F. sanguinea being discovered by 

 myself at Blackwater in Hampshire ; I have also added 

 F. exsecta and F. umhrata, Ponera puncfatissi7na, Myi-- 

 mica lippula and M.fugax to our list; — this convinces me 

 that, if entomologists were to collect the Formicidcs, par- 

 ticularly in the more northern parts, our list of British ants 

 would soon be materially increased. 



I have failed to discover the common wood ant near Ilfra- 

 combe, although I still think it must inhabit some of the 

 woods in that district ; probably those at Lee, which I have 

 not visited. At Lynmouth the species is common enough in 

 the woods leading up to Water's Meet; at this latter spot I 

 may notice that Formica fusca is extremely abundant under
