56. ? Tachinus frigidus, Er. Gen. et Spec. Staph. 256, 21; Kr. 
Ins. Deutsch. ii. 402. 
I have taken in Inverness-shire a specimen belonging to the 
genus Tachinus, which I cannot consider specifically identical 
with any of our recorded species. It agrees tolerably well with 
Kraatz’s description of 7. frigidus (Erichson’s description appears 
to have been drawn up from two species), a very rare species, of 
which, according to Kraatz, there are three specimens in the 
Berlin Museum, two of them from Unalaschka, the other from 
the Tyrol; these are all males and the female is still undescribed ; 
my specimen being a female, I cannot, under the circumstances, 
feel sure that I am right in my determination of it. The following 
is a description of the structure of the seventh abdominal segment. 
The seventh dorsal plate ends in three long teeth, of these the 
middle one reaches beyond the side ones, and its thin apical part 
is longer than in 7. proximus or rufipes. The notch between the 
middle teeth of the seventh ventral plate is not simple, but has a 
triangular projection at its base as in Z". pallipes. Thus, the 
structure of the seventh segment on the upper side most re- 
sembles 7’. proximus, but on the under side is most like 7’. pal- 
lipes. The insect is altogether smaller and rather more finely 
punctured than its allies.—D., S. 
57. Mycetoporus tenuis, Muls. Op. ii. 67. 
I have found this species on the top of Cheviot and also on a 
mountain between Strath Farrar and Strath Cannich, Inverness-
