ON THE SPECIES OF EMPIS ALLIED TO E. STERCOREA, LINN. 
(INCLUDING ONE NEW TO SCIENCE). 
BY G@. H. VERRALL. 
These species of Hmpis are well distinguished by their yellow 
colour, elongate form, long, thin, bare legs, long antenne (especially 
the basal joint), and by the eyes of the male being widely separated. 
In the ‘ Berliner entomologische Zeitschrift,’ xi (1867), p. 11—21, 
Loew has revised the European species and described ten, adding 
another at page 158, and a twelfth at xii, p. 82; of these twelve, six 
were new or undistinguished, and Loew says that he doubts not, but 
that there are many other rare species which are overlooked, from the 
very great abundance of the common species allied to them. He 
describes— 
stercorea, Linn. testacea, F. 
stigma, Mq. punctata, My. 
dimidiata, Lw. ignota, Mg. 
univittata, Lw. semicinerea, Lw. 
stercorea, var. b, Zett. trigramma, Iq. 
leta, Dw. lutea, Wy. 
equalis, Lw. nana, Lw. 
bilineata, Lw. 
punctata, F. 
testacea, Zett. 
Closely allied to this group come a few other species distin- 
guished by their shorter antenne, and (except in scutellata, Curt.) 
by the eyes of the male touching on the front; of these I shall only 
notice scutellata. 
I have hitherto found in Pritain only stercorea, punctata, trigramma, 
lutea, scutellata, and an undescribed species allied to lutea, which I 
have called concolor. Concerning these, I have the following remarks 
to make. 
1. Stercorea, which extends over middle and northern Europe, is dis- 
tinguished from the other British species by the single distinct 
black line down the thorax, and its generally larger size ; scwtellata 
has only one line on the thorax, but has the basal joints of the 
antenne shorter and yellow: of the European species, dimzdiata, 
from southern Germany, is very much allied, but the prothoracie 
stigma is concolorous with the thorax, instead of black, the thorax
