ably long. This is particularly the case with the anterior 
pair of some beetles, as Acrocinus longimanus, Scarabeeus 
longimanus L.?, in which they are so long as to make the 
males of these individuals rather inconvenient in a ca- 
binet. Amongst British beetles Clytra longimana and 
Dorytomus longimanus are also remarkable in this respect. 
In some other males the middle pair are the longest; as 
in Anthophora retusa Latr., a kind of wild-bee’. There 
are two known instances of remarkably long posterior 
legs in the Capricorn tribe, which I suspect belong to the 
present head. One is Saperda hirtipes Oliv. *, in which 
the hind-legs are longer than the whole body, and adorn- 
ed with a singular tuft of hairs; and the other a Clytus, 
I think, which Mr. MacLeay purchased from the late 
Mr. Marsham’s collection, in which the hind-legs are 
not only very long, but have tarsi convolute, like some 
antenne. From analogy I should affirm that these were 
the characters of male insects. 
To come to the parts of legs. Sometimes the core of 
the last mentioned sex are distinguished from those of 
the female by being armed by a mucro or spine. Thus 
the male of Megachile Willughbiella, and others of that 
tribe, have such a spine on the inner sides of the anterior 
coxa‘, The Trochanter also of some differs sexually ; 
and you will find that the posterior one of the male in 
Anthidium manicatum is of a different shape from what 
it is in the female*. In Sphodrus leucophthalmus, one of 
* Mr. W.S. Macleay has cbserved to methat S. Jongimanus L. be- 
longs to the Thalerophagous circle of Petalocera, and that S. bimucro- 
natus of Pallas may be regarded as almost of the same genus.
