NOTES ON HYMENOPTERA, 89 
Singular to relate I have never taken any species of Exetastes, 
though apparently abundant elsewhere. 
The genus Limneria abounded ; many species I have not been 
able to determine with accuracy. 
Mesochorus also gave me thirteen species, among them being 
M. thoracicus, M. strenuus, and M. anomalus. 
In the genus Megastylus I have to add M. borealis, Holmg., 
taking at the same time JZ. cruentator and M. mediator. 
In the Bracons I can also add several species new to Britain, 
the most interesting one being the fine Homolobus discolor. I 
took five females of this insect by beating some hazel. This 
appears to be the largest species of that tribe, and may easily be 
distinguished by the closed areolet of the inferior wings, as in 
Zemiotes, but having the sessile body of a Macrocentrus. 
Rogas brevicornis, Wesm., and R. tristis, Wesm., also occurred, 
and appear to be previously unrecorded. 
Among others I may also mention Heterogamus dispar, 
Eubadizon pectoralis, Ichneutes reunitor, Macrocentrus marginator, 
M. thoracicus and M. linearis, Phenolexis petiolata, Symphya 
hians, Celinws niger, C. gracilis and C. elegans; and many 
species of Alysia. 
The Oxyura also yielded many species; the difficulty of their 
determination allows me to give two only as new, viz., Spilomicrus 
major, Voll., and S. flavipes, Thoms. 
I added also the singular Helorus anomalipes and Ismarus 
campanulatus to my captures; and taking into consideration the 
extremely unfavourable season have no reason to be dissatisfied 
with my success in 1879. 
I may also mention the occurrence in July of Fenus minutus, 
Tournier. This appears a very distinct species, and I therefore 
give a short description of it. I only obtained one female. 
Fonus minutus, Tournier.— Length 44 lines; black; apex of 
first segment and apical half of second segment of abdomen red ; 
tarsi and extreme base of tibie dark reddish; aculeus about as 
long as the first abdominal segment. 
Shere, March 1, 1880.
