Ncio Nests of Ants Inj MyrmecopMlous Coleoptcra. 417 



this beetle protects itself against the ants if attacked, as 

 also the next species. Wasmann took one specimen in a 

 nest of Formica sanguined in May in Dutch Limburg, and 

 has also caught it on the wing. 



[Note. — Formica pratensis, DeG. {congerens, Nyl.), appears to be 

 very rare in Britain; it has been recorded from Bournemouth, 

 Holnest, Porlock, Exmouth, Raunoch and elsewhere in Scotland. 

 Possibly some of these records are in error as Saunders only gives 

 Bournemouth and Rannoch. I have never been able to find it, but 

 I have found nests of the subspecies rufa-pratensis, Forel, at Nethy 

 Bridge, which have the colouring oi pratensis without its hairiness.] 



ThiasopJdlia inquilina, Mark. 



Normal host. — Lasius fnliginosus, Ltr. 

 Dr. Power took a specimen with Formica rufa at Burn- 

 ham Beeches on June 21st, 1857. 



Ilyohates glabriventris, Rye (ionnairei, Fvl.). 



This species appears to be very rare both here and on 

 the Continent. It was taken sparingly by Dr. Power 

 with Zasius fuliginos7(.s at Mickleham in May and June 

 1863, in the runs of the ants in company with Homoeusa 

 acuminata. (E. M. M., I, 1865, p. 212.) Wasmann took it 

 with Lasius hrunneus in July in Dutch Limburg and 

 remarks, " perhaps a regular guest of the ant " ; also with 

 Lasius alienus in Vienna. Sklitzky records it with Lasius 

 niger in Bohemia. 



Fauvel described it from a specimen taken by M. 

 Bonnaire in Compiegne, but does not record how it was 

 captured. (" Bui.* Soc. Normandie," IX, 1865, p. 287.) 



Mr. Elliman swept two specimens in a moist wood near 

 the Chiltern Hills on June 6th, 1897, and remarks that the 

 atmosphere at the time was remarkably still and warm. 

 (E. M. M., 1897, p. 279.) 



We now come to the genus Dinar da. Father Wasmann 

 tells me their eggs are deposited in the soil of the nests, 

 the larvae emerging there. The copulation of Dinarda is 

 the same as that of Lomechusa and Atemcles. 



Dinarda mdrheli, Kies. 



Normal host. — Formica rufa, L. 



Wasmann records a single specimen in a nest of Formica 

 sanguinca in May in Dutch Limburg. 



I have bred this species in my observation nests of
