been included under it ; as Dr. Horn remarks (Classification of tho 

 Coleoptera of North America, p. 213), the affinities of the Malachiida? 

 appear to conduct directly from the Lampyridae to the Cleridae, with a 

 strong tendency to inosculate, through Bytnrus, with the Dermestidse. 



The larva) of the Dasytina appear to be elongate and rather hairy, narrowed in 

 front and widened behind, and terminated by two short pointed cerci ; the untcmiiu 

 and legs are short or very short ; those of Dasytes serricornis and Haplocnemut 

 impressuf 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. 



I. Tarsal claws broadly toothed, but without membranous 



appendages ' . . . . DASITES, Payk. 



II. Tarsal cluws with a connate pellucid membrane. 



i. Tarsi somewhat thickened ; upper surface coarsely 



pubescent PSILOTHBIX, Redt. 



ii. Tarsi long and slender ; pubescence of upper surface

III. Tarsal claws with a free membrane, which is appen- 

 diful.iti', and as long as the claws ; form comparatively 



short and broad HAPLOCNEMDS, Steph.

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 tho known species occur in Europe, of which four only inhabit 

 Britain, one of which is somewhat doubtful. 



I. Thorax not transverse ; elytra rather roughly punctured. 



(Sub-gen. Mesodasytes, Huls.) 

 i. Legs, in part at least, testaceous.

only of the antennae testaceous I). FLAVIPES, F. 



2. Eyes larger in male ; female with the first and second 



joints of the antennas testaceous D. OCPLATTJS, Kies. 



ii. Legs entirely dark D. .EBOSUS, Kies. 



II. Thorax slightly transverse; elytra closely and rather 



finely punctured ; colour entirely black (Dasytes, i. sp.) . D. MGKU, L. 



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. 



D. flavipes, F. (plumbeus, Mull., nee Muls. ; tibialis, Zett. ; coxa- 

 lit, Muls.). Elongate, linear and parallel, a little widened behind in 

 female, of a dark bronze-black olive-greenish colour, with fine light 

 pubescence, and a strong intermixture of long upright blackish pilose
