This is a very beautiful Infed : it's length is about half an inch j it*s breadth near tWrd 
thirds of it’s length : the thorax is very large and broad, equalling the diameter of the 
wings j it is of a green colour, with a yellow braffy caft, and has feveral hollow fpots 
upon it: the head is in a great meafure received into, or immerfed under, the anterior 
part of this j the exterior wings are of a fine, glofiy, metalline-yellow, with only a flight 
tinge of green, and they have each about eight ftriss on them. 
This fpecies is very common in damp places, near waters. 
Bupreftis fufco-cenea , glabra , nitida , thorace fumbarginaio* 
The brownijh braffy Bupreftis , with a fubmargmated thorax* 
This is a very fmall fpecies t the whole Infedt is of a glofiy brafs-yellow, with an admix- 
ture of brown : the eyes are moderately large, and very prominent ; the antennae arO 
fhort: the thorax is fhort, but it is broad, and hollowed, and fiightly marginated : thd 
exterior wings are very bright and glofiy, and are finely ftriated, the firiae being formed 
of very minute and elegant points: the legs are fender and black, as is alfo the under 
furface of the body : the fnout is prominent. 
It is very frequent among the reeds on the little ifiands formed by the Thames, about 
Chifwick and Brentford. 
Bupreftis ceneo-nebulofa antennis clavatis. 
The brajjy and clouded Bupreftis , with clavated antennce* 
This is a fmall fpecies, it fcarce equals a flea in fize; the belly and lowed part of 
it’s body is all black j on the upper part it it is all over of a braffy yellow* with a mix¬

and on each there are two fpots fo difpofed, that they make a fquafe figure together, 
when the wings are clofed ; thefe are of a bright and unmixed yellow. 
It is a native of Virginia, and is fometimes found alfo with us about the ii^es of rivers* 
Petiver has figured it under the name of Cantharus Marianus elegans viridis vaginis fulca-
