426 Mr. H. St. J. Donisthorpe on the Colonisation of 



in May. The shape and hardness of this and the next 

 species protect them from the ants. They belong to the 

 indifferently treated guests, though Myrmetes is sometimes 

 licked by its hosts. 



Myrmetes piceus, Pk. 



Normal hosts. — Formica rufa, L., and pratensis, De G. 



Wasmann took a single specimen in a nest of F. san- 

 f/uinea, which contained rvfa as slaves in Dutch Limburg. 

 I have bred this species in my F. rufa observation nest 

 many times, and on May 10th, 1909, I noticed a pair in 

 co'jp. in a small Formica observation nest, and also the 

 licking of a specimen by an ant. 



Am'photis marginata, F. 



Normal host. — Lasiiis fuliyinosvs, Ltr. 

 Taken on the wing in the summer of 1906 at Woking 

 by Champion. (E. M. M., 1906, p. 255.) 



Cetonia fioricola, Hbst. 



Normal hosts (for larvae and pupa). — Formica rxfa, L., 

 and i3ratcnsis, De G. 



A single larva was found by Wasmann in May in a nest 

 of Formica sanguinea, and another with L. fulicjinosus in 

 Dutch Limburg. Wasmann has pointed out that the % 

 Cetonia lays her eggs in the ants' nests, and that she is 

 attacked by the ants. 



Rupertsberger describes the entrance of a $ Cetonia 

 which he saw fly up, into a nest of F. 2Jratensis, to lay her 

 eggs. ("Wien Ent. Zeitg.," 1893, p. 249.) 



Weaver recorded that the larvae lived in the nests of 

 F. rufa in Scotland. (Trans. Ent. Soc. Lend., Nov. 1st, 1852.) 



Lloyd records finding larvae and pupae in nests of F. rufa 

 at Rannoch. (E. M. M., 1892, p. 310.) 



I found the empty pupa cases in the nests at Rannoch 

 in June 1900, and larvae in some numbers in a rufa nest 

 at Nethy Bridge last May. 



W. Evans bred the beetle from larvae taken mF.rufa 

 nests, Upper Forth. (" Ann. Scot. Nat. Hist.," 1903, p. 95.) 



Clytlira ^-punctata, L. 



Normal host (for larva and pupa). — Formica rufa, L.
