On the 20th of August 1 had the pleasure of finding three females burst from 
the pupa: one male that I had already hatched a few days before, and 
was tolerably lively; I put him among the females in a very large glass 
jar, but they did not incline to copulate, they grew more lively by being 
held in the warm hand, and ran about briskly, and now and then attempt¬ 
ed to fly, but showed no signs of a desire for sexual intercourse; covered 
up from the light in a few seconds they became indolent again, bending 
themselves round into a semicircle, bringing their legs together, and 
lying as though perfectly asleep on one side. I thought also the approach 
of any one seemed to rouse them as though sensible they were looked at; 
sometimes they would get on their backs, and whirl round with conside¬ 
rable velocity. As flies are fond of sweet things, I presented them with 
a bit of paper smeared with treacle, but they did not regard it. Even in the 
hand, if the light was excluded, they would go into a torpid state, notwith¬ 
standing the warmth, by uncovering him he became restless and buzzed 
about. They lived only a few days, and then died; the air of the city I 
thought might not quite suit them, as well as their confinement. 
It is to be remarked'how much this family are alike in color, nearly atl 
having the red anus, and black and red thorax. 
. The following is a description of this new species, after the manner of 
entomologists.
