the species will be found in the Katalog. Paldarkt.. Dipt., I., 
327, 332, 339, and references to some or all occur in Strobl 
Mitt. ver. Steiermark, 1894, 208., Riedel Abh. Lehr. Crefeld, 
1913, Goetghebuer and Tonnoir Bull. Soc. Ent. d. Belg., 
1920. The drawings by Wulp in his last paper are very use- 
ful, but as the publication is not easily accessible to Yorkshire 
dipterists, I have mounted and photographed the genetalia of 
three species taken in Yorkshire which agree with his drawings 
and descriptions. 
T. marmorata Meig. (< confusa v. d. Wulp.) is widely dis- 
tributed, and frequently taken on walls quite as often in towns 
as in the open country districts ; it is smaller in size than the 
other two, the is easily separated as the illustration will 
show, but the is not so easily distinguished, the pleurae are 
whiter and contrast with the redder abdomen, and the wings 
are more decidedly marmorated. 
T. anonyma Bergr. and signata Staeg. approximate closely 
in size and general appearance ; again there is no difficulty 
with the (Js. Wulp gives as a guide the brown side stripes 
on the abdomen of signata. I have not found this very satis- 
factory, over a series the stigma of anonyma seems darker and 
shorter than that of signata, but the two females are very much 
alike. 
I found anonyma Bergr. near Austwick, i6-ix-2i, in a 
small wood with open ditches carrying water from springs, 
and later in the month and in October I found signata Staeg. 
with it in similar places near Austwick and at Helwith Moss ; 
these two species appear to be recognised as autumn species 
by previous writers. T . anonyma Bergr. is much rarer than 
signata Staeg, and is not mentioned by Strobl and Goetghebuer. 
Wingate's table is satisfactory if the confusa be altered to 
marmorata and the marmorata to anonyma.

beach . 
Among the contents of British Birds for March we notice a contin- 
uation of W. Rowan’s illustrated observations on the breeding habits 
of the Merlin, and a report on the ‘ British Birds’ Marking Scheme for 
1921, ’ by H. F. Witherby. 
Among the numerous and well-illustrated papers appearing in the 
numbers of Conquest recently published, we notice ‘ Exploring the
