330 THE MYRMECOPHILOUS COLEOPTERA 



The following species may be enumerated •which have been recorded 

 with ants, but however, often, and probably generally occur elsewhere. 



CalUcerus rigidicornis, Er. With L. fuliginosus and niger, and F. rufa. 

 Homalota analis, Gr. Frequently with Formica rufa and also with F. exsecta, 



&c. 

 Homalota nitidula, Kr. Lasius fuliginosus. 

 Hom.alota oblongiuscula. Slip. Lasius fuliginosus. 

 Homalota exarata. Slip. Lasius fuliginosus. 



Heterotliops nigra, ( =• quadripunctula, Brit. Cat. ?) Dr. Joy has proved this 

 species to be very abundant in moles' nests. I am not quite satisfied if 

 specimens taken with Formica rufa and Lasius fuliginosus are the same 

 species, they appear to me to be a little larger, the punctuation more 

 alutaceous, and consequently not so shining. 



Staphylinus stercorarius, 01. This species has been taken on various occasions 



with ants, Myrmica scahrinodis and ruginodis, and Lasius jlavus, &c. 

 Staphylinus latebricola, Gr. Has been recorded with Formica rufa. 



Medon bicolor, 01. Lasius Jlavus, &c. 



Leptinus testaceus, Miill. Lasius fuliginosus. 



Scydmcenus pusillus, Miill. Formica rufa and Lasius fuliginosus. 



Euthia j)licata, Gyll. Formica rufa. 



Triclionyx sulcicollis, Reich. In old stumps often in company with ants. 

 Bedell records it with Ponera contracta near Paris. 



Ptenidium turgidum, Th. Often with ants. 

 Ptenidium gressneri, Er. Lasius fuliginosus. 



Dendrophilus punctatus, Hbst. In birds' nests, dead animals, rotten Avood, 

 hornets' nests, cellars, &c. It, however, frequently accurs with ants, both 

 here and abroad. Lasius fuliginosus, Formica rufa, and I have bred it 

 from a nest of Formica exsecta. 



Abraeus glohosus, Hoff. Lasius fuliginosus ; the larva was described by Penis 

 from a nest of this ant. 



Corticaria serrata, Pk. Formica rufa, Lasius fuliginosus, &c. 



Cetonia aurata, L. Larva and pupa occasionally in the nests of Formica rufa.
