72. Mufca chamseleon : fcutel two-toothed, yellow ; 
abdomen black, with three triangular yellow fpots on 
each fide, and one at the end. It inhabits Europe. This 
is one of the mod remarkable fpecies ; it is a large black 
fly, with a broad flattifh abdomen, having the iides of 
each fegment yellow, forming fo many abrupt femi-bands 
acrofs that part. It proceeds from an aquatic larva of 
very confiderable fize, meafuring two inches and a half in 
length, of a fomewhat flattened lhape, and of a brown co¬ 
lour, with a narrow or Render front; the body widening 
by degrees towards the middle, and from thence gradu¬ 
ally tapering to the extremity or tail, which is terminated 
by a circle of radiating or diverging hairs. This larva is 
common in ftagnant waters, during the fummer-months, 
and pafles into its chryfalfs flate without calling its Ikin, 
which dries over it, fo as to preferve the former appear¬ 
ance of the animal in a more contradled form, as fully ex¬ 
plained under the article Entomology, vol. vi. p. 837. 
The perfect infedt is Ihown at fig. 10 of the annexed Plate. 
73. Mufca vermileo, the worm-catcher : cinereous ; 
abdomen with three rows of black dots; wings immacu¬ 
late ; thorax fpotted. This is a middle-fized fly, of a 
fomewhat lengthened form, with a diftant relemblance to 
a Tipula; it is of a dull yellow colour, with tranfparent 
wings; the thorax marked above by two black lines, and 
the abdomen by triple rows of black fpots. The larva 
meafures about three quarters of an inch in length ; and 
is of a pale yellowifli-grey colour, Render or iharpened in 
front, and growing gradually broader towards the tail. 
It is found in the fouthern parts of Europe ; and is not un¬ 
common in fome diftridts of France. It is remarkable for 
p radii fin g a method exadtly fimilar to that of the Hemero- 
bius formicaleo, in order to obtain its prey; excavating 
a circular pit or cavity in the dry fand ; concealing itfelf, 
waiting the arrival of any fmall infedt which may happen 
to fall into it; and, after abforbing its juices, throwing out 
the exhauiled remains to a confiderable diftance from the 
cavity. This larva feems to have been firft obferved and 
deferibed by Reaumur, in the Memoirs of the French 
Academy for the year 1752. It afiumes the flate of a chry- 
falis by calling its Ikin, which of itfelf rolls to the hinder- 
part of the body : the chryfaiis is<>f a dull reddiih colour, 
and is rounded or clubbed at the upper-part, fuddenly ta¬ 
pering from thence to the extremity ; and, after lying nine 
or ten days, it gives birth to the perfedt infedt. 
74. Mufca eolombafehenfis : black, with white incifures 
of the abdomen, lhariks, and tarfi. This fpecies is found 
in many parts of Ruiiia and Siberia, particularly in the. 
fpring and autumn. It is extremely troublefome, and 
often fatal to the cattle which are attacked by it. It in- 
finuates itfelf into the nobler parts, and deftroys the crea¬ 
tures thus affedled in the courfe of four or five hours. 
75. Mulca papataci: antennse, body, and wings, hairy. 
It inhabits Italy ; is very fmall, and very troublelome in 
the night during the whole fummer. The eyes are black ; 
the abdomen red. 
76. Mulca pendula : downy ; thorax black, with four 
yellow lines ; abdomen yellow' with tranfverle black lines, 
connedled by a longitudinal ftripe. The pendulous fly 
is a moderately-large and very-beautiful infedt. Its co¬ 
lour is black, with four bright yellow ftripes down the 
thorax, and three broad interrupted bars acrofs the abdo¬ 
men. Its larva, which is an inhabitant of llagnant water, 
is of a remarkable appearance; it is furnilhed with a tail
