Mr. F. W. Edwards on British Limnobiidae. 219 
hirsutipes Macq., and andalusiaca Strobl. JI do not con- 
sider, however, that these are really distinct. I have seen 
British specimens which correspond fairly well to the three 
forms defined by Kuntze, and they all have identical male 
hypopygia, while the differences between them in other 
characters do not seem to be sharply marked, but are 
bridged by continuous variation. In general the small 
specimens seem to have less distinctly clubbed femora, 
somewhat shorter hair on the male tibiae, and less con- 
spicuous dark borders to the cross-veins. 
T. pilipes probably has a wider distribution than any 
other crane-fly. An examination of the hypopygia of a 
number of specimens in the British Museum shows that it 
occurs in Uruguay, Ecuador, Argentina, the Falkland 
Islands, South and East Africa, Victoria, Queensland, the 
Sandwich Islands, Madeira and Palestine ; it is also known 
to occur in North Africa, the Canaries and North America, 
as well as throughout Europe. It may be doubted whether 
the genus really contains more than one cosmopolitan 
species; from an examination of types or other specimens 
I can say definitely that haligena Woll., hirtipes Walk., 
inconspicua Lw., lateralis Grim., and reciproca Walk., are 
all synonymous with pilipes F. It is not easy to account 
for the widespread occurrence. The larvae are said simply 
to live in “moist earth,” hence there seems no special 
reason why the species should be spread by commerce. 
GNOPHOMYIA. 
A specimen of @. tripudians has been taken at Cambridge 
by Mr. F. Jenkinson. Other species of this genus may 
be expected to occur in Britain. 
CRYPTEBIA. 
The most important distinguishing character of this 
genus is the fusion of the three or four basal segments of 
the antennal flagellum into a single large conical segment. 
A similar fusion takes place in the genera Cladura, Ptero- 
chionea and Chionea, all extra-British genera which differ 
from Crypteria in having only a single clasper, instead of 
two, on the side-piece of the male hypopygium. 
C. limnophiloides Bergr. Since this was recorded 
(Proc, Ent. Soc. London, 1919, p. xlix), a male has turned 
up among the accessions in the British Museum from Middle 
Park, Pool, Glamorgan, 15 x. 1895 (Dr. J. H. Wood).
