be regarded ns a guest/^ but admits tliat in some cases, such 
as that of Falagria thoracica, the real relations are still doubt- 
ful. From his owti examinations of aiits^ nests he divides the 
species o^Lasius Formica and those of investigated 
by him into four groups in accordance with the nature of their 
guest beetles. 
I. The fifst of these includes F. rufa (Linn.) with F. pinopliila (Schenk), 
polyctcna (Fdrst.), iriincicola (Forst.), congerens (Nyl.), and cxsertd (Nyl.)j 
F. truncicola (Nyl.) also probably belongs to this group. Its peculiar guests 
are Thiasophila angulata, Homalota JlavipeBj and anceps, Oxypoda Juxthorrhodj 
Lcptacinn^ formicetorum. Stenns atei rimuSj Myrmecoxcnus suhterraneus, tmdi 
Dejidrophilus pygmmis. The Formicide Stcnamma tvcstwoodii is also found 
in nests of jF. rvfa and congerens. II. The second group includes F. sangnU 
nea (Lat.), rnjibarhis (Fab.), fusca (Linn.), and Myrmica Icevinodis (Nyl.)< 
Guests, Lomechusa strumosa, species of Aiemelcs and Finarda, Iletcerius ses- 
quico7-nis. III. The third group consists of Lashis ftdiginosus alone, and has 
numerous guests, especially Oxypoda vittata^ Amphotis marginata, aiid most 
of the species of Myrmedonia. Thiasophila inquilina, Homalota conftisa, and 
Dcndrophilus pnnctatus correspond with the species of the same genera be-* 
longing to the first group. IV. The fourth group includes the remaining 
species of Lasius, Tapinonia erraticum (Lat.) and Tctramorium ceespitiwit 
Guests Claviger, Chcnnkinij Centrotoma, Batrisus, Trichonyx^ some rard 
Myrmcdonicej Furyusaj and Lamprinus. The genera Jlaploglossa and Homoe- 
lisa are common to groups III. & IV. Species ordinarily peculiar to a par- 
ticular species of Ant are sometimes found in the nests of other species } in 
some cases, under these circumstances, they present slight variations. The 
author gives a list of the Ants’-nest Beetles observed by him (/. c. pp. 108-* 
112), with particulars of their mode of occurrence. He records the fact that 
he has several times seen Lomechusa strumosa seized and licked or sucked by 
Formica sanguinea, and that E. Schroder has observed Loinechusce being fed 
by the Ants (/. c. p. 112).
