THE ENTOMOLOGIST. 207 
they flew very little before sunset, but about dusk they began 
to fly straight down the different paths by dozens, and I did 
not see any settled after this. I should have taken more, but 
I ran short of pins. I went again on June 6th, and took 
fifteen more,—all I saw then; and on June 9th I again took 
nine, some of which were very much faded, and I have not 
seen any since.—David Price; West Street, Horsham. 
Captures in Sutherlandshire—Thinking it may interest 
some of the readers-of the ‘ Entomologist,’ I beg to give you 
the names of the Lepidoptera that I took in Sutherland 
last month:—Ccenonympha Davus, plentiful on the bogs; 
Melanippe tristata, very plentiful on the side of the “ burns ;” 
and one specimen of Plusia Chrysitis. The Tristata were not 
black, but a dark dusky brown. Being on a fishing excursion 
I unfortunately only got a few specimens of these species.— 
C. L. Adams; Walford Manor, Shrewsbury, Aug. 15, 1874. 
Macherium maritimum (Fam. Dolichopide).—Macherium 
maritimum was first named and described as anew genus and 
species by A. H. Haliday, in 1831; and its economy has 
been lately observed by Mr. Joshua Brown, of Bartonbury. 
The cocoons were found in the beginning of June, on the 
sands at a bay about two miles beyond the town of Weston- 
super-Mare: Mr. Brown kept them moist with a little salt 
water, and the flies came out during a week about the middle 
of June. The pupa is pale, about three and a half lines in 
length, decreasing in breadth from the head to the tip of the 
abdomen; the head and the thorax are large, and closely 
connected ; there are eight abdominal segments, and the legs 
and rudimentary wings are distinct; the antennex are two- 
thirds as long as the body, and much longer than those of 
the developed fly; the scape is thick; the flagellum is 
setaceous and black at the base. The cocoon is pale gray, 
_elongate-oval, about six lines in length, smooth without and 
within, and appears to be composed of fine mud.—Francis 
Walker. 
Microgaster in Brazil.—In Hymenoptera and Diptera 
there are often examples of nearly allied species inhabiting 
wide-apart districts of the earth. Microgaster, whose larvee 
form little yellow cocoons attached to the skins of caterpillars, 
are well known in Europe, and I am indebted to Mr. F. 
Smith, of the British Museum, for a mass of white cocoons
