INQUILINE AND OTHER INHABITANTS IN NESTS OF ACULEATE 

 EYMENOPTERA. 



BY W. H. TUCK, M.A. 



For the last seven autumns (1889—1895) I have examined a large 

 number of various nests, and am now able to give a complete list of 

 my captures. I am indebted to Mr. E A. Butler for valuable assistance 

 in determining the different species, and to Dr. E. Meade for the list 

 of Dipt era. 



The seasons of 1890 and 1893 were by far the best for the rarer 

 captures. 



I may mention that the earliest wasp in my district is Vespa 

 sylvestris, and the latest V. vulgaris. I have found a nest of the latter 

 in working order as late as December 5th. 



The nests of the large Bombi in this enclosed country are not 

 easy to find, and still more difEcult to explore, except when quite in 

 the open. 



The following are the nests opened up, all in my own parish, and 

 as a rule single-handed, as I have no one in Suffolk who can render 

 me any assistance: — Vespa crabro (2), V. vulgaris (94), V. germanica 

 (30), V. rufa (1), V. sylvestris (3), Bombus veimstus (6), B. agrorum 

 (8), B. LatreilleUus (2), B. Jwrtorum (1), B. liortorum [Harrisellus] 

 (1), B. sylvarum (3), B. lapidarius (2), B. terrestris (1). 



COLEOPTERA. 



The names are nearly all taken from Sharp's Catalogue, 2nd 

 edition, 1883. 



Bradycellns distinctus {Bombus agrorum). 



Harpalus rsneus (-B. hortorum), I found about six of these in the cells. 



Amara lunicollis {B. venustus), probably only casual intruders. 



Anchomenus prasinus (T'^espa vulgaris, germanica). 



Bembidium 4:-maculatum {B. muscorum, sylvarum). 



Trechus minutus {V. vulgaris, B. sylvarum) ; obtusus {V. vulgaris). 



Calathus cisteloides (V. vulgaris), on several occasions. 



Pterostichus madidus {V. vulgaris, germanica). 



Metabletus foveola {V. vulgaris, germanica). 



Eelophorus nubilus {V. germanica); griseus ( F. germanica); brevipalpis 

 (F. vulgaris). 



Cercyon granarius {V. vulgaris) ; lateralis (B. LatreilleUus). 



Megasternum boletophagum {B. agrorum). 



Aleochara masta {V. vulgaris), not very abundant; fuscipes {V. vulgaris). 



Myrmedonia limbata {V. vulgaris). 



Homalola ceneicollis {V. vulgaris) ; fungicola (J', vulgaris, B. agrorum) ; fusca 

 ( V. vulgaiis).
