MIDLAND MYRMECOPHILOUS NOTES FOR 1907. 57 



of Formica rufa, March, April, May, June ; Knowle, Bewdley. Oxypoda 

 HOiMORRHOA, Salil. — In nests of Funnica rufa, April; Knowle. Thiaso- 

 PHiLA angulata, Et. — Abundant in nests of Formica rufa, all seasons ; 

 Knowle, Bewdley. Dinarda markeli, Kies. — This beetle occurred in 

 nests of Formica rufa ; Bewdley, Knowle. Dinarda dentata, Gr. — 

 This species has occurred abundantly in nests of Formica sawiuinea in 

 April, at Bewdley. It has not apparently been recorded from the 

 Midland counties before. Myrmedonia humeralis, Gr. — Found abun- 

 dantly with Formica rufa on May 12th, running on pathways in tracks 

 of the ants in bright sunshine, when they are very active. During 

 the dull parts of the day they were not to be seen. Several other 

 specimens were taken from time to time during this month and the 

 beginning of June. We have never taken this beetle inside the nest, 

 and it is apparently always found in the positions indicated. Drusilla 

 CANALicuLATA, F. — In nests of Formica sani/uinea, April, May; Bewdley. 

 Notothecta flavipes, Gr. — Abundantly in nests of Formica rufa : 

 Knowle, Bewdley. Notothecta anceps, Er. — Taken with Formica 

 rufa : Knowle. Homalota nitidula, Kr. — Taken with Lasius fuli- 

 (linosi(s ; Knowle. It has been recorded with this ant before, but 

 Donisthorpe is of opinion that they are chance visitors (Proc. f.anc. 

 and L'hes. Fnt. Soc, 1905). Quedius brevis, Er. — In nests of Formica 

 rufa and F. sancjninea at Bewdley, and with Formica rufa at Knowle. 

 This species is generally associated with Formica rufa and Lasius fuli- 

 (/inosus. Quedius mesomelinus. Marsh. — A specimen of this beetle was 

 found in the nest of Formica rufa at Knowle. It had been badly injured 

 by the ants, and was in a dying condition ; Donisthorpe records taking 

 it in plenty with Lasius fuliginosus, and, on introducing them into his 

 observation nest of Formica rufa, they were immediately torn to pieces. 

 They are probably chance visitors. Xantholinus atratus, Gr. — 

 With Formica rufa and also Lasius fuliiiinosus at Knowle, and w4th 

 Formica rufa at BeAvdley. This is apparently the first British record 

 of its occurrence with Lasius fulif/inosus. It, however, occurs with this 

 ant on the continent. Leptacinus formicetorum, Mark. — Taken with 

 Formica rufa at Bewdley and Knowle. Two specimens were taken in 

 July at Knowle, which appear to be broader and more robust than the 

 typical form. Othius myrmecophilus, Kies. — Captured with Formica 

 rufa at Knowle and Bewdley. Ptenidium formicetorum, Kr. — In nests 

 of Formica rufa ; Knowle. Dendrophilus pygm.eus, L. — In numbers 

 with Formica rufa : Knowle. Myrmetes piceus, Pk. — In nests of 

 Formica rufa at Knowle. Monotoma conicicollis, Aub., and M. 

 formicetorum, Th. — Both taken with Formica rufa at Knowle and 

 Bewdley. Clythra quadripunctata, L. — Larvfe and pupae of this 

 species were taken in nests of Formica rufa at Knowle. 



Proctotrupidae. — Laginodes pallidus, Boh. — In a nest of Formica 

 rufa at Knowle, in July. 



We have, unfortunately, been unable to give as much time to this 

 subject as we at first hoped to do, but during the year we collected a 

 large amount of material, which is gradually being worked out, and 

 "we hope to record species of other orders at a later date.
