been included under it; as Dr. Horn remarks (Classification of the 
Coleoptera of North America, p. 213), the affinities of the Malachiide 
appear to conduct directly from the Lampyride to the Cleride, with a 
strong tendency to inosculate, through Byturus, with the Dermestide. 
The larve of the Dasytina appear to be elongate and rather hairy, narrowed in 
front and widened behind, and terminated by two short pointed cerci; the antennzw 
and legs are short or very short; those of Dasytes serricornis and Haplocnemus 
impressus are figured by Westwood (Classification, i. p. 259, fig. 28, 18 and 22); they 
are found in old trees, and are, apparently, carnivorous; the perfect insects are 
usually found on flowers, and are either more or less elongate, or rather short oblong 
and convex, with the upper surface very often clothed with long and thick hairs.

This genus contains about one hundred and fifty species, and is 
probably much more extensive, as its members are distributed over the 
whole world from Siberia to the Australian region, and throughout 
Europe, Asia, and North, Central and South America; they are linear 
and narrow insects, of a dark colour, clothed with more or less long and 
thick villose pubescence ; they are found on flowers and shrubs ; about 
sixty of the known species occur in Europe, of whieh four only inhabit 
Britain, one of which is somewhat doubtful.

The synonymy of the species is, in some cases, very confused ; I have, 
for convenience sake, omitted the name of D. plumbeus, which has been 
applied by authors to more than one species.
