tlie Rosa for size and colour ; the Schrankella is also a 
very pretty species; and perhaps the commonest of all 
the cingulata is the prettiest of all, with its yellow nose 
and red abdomen; in the next section we may point out 
the longipes as being a very elegant insect,* as are also 
the chrysosceles and the helvola. In this section we find 
those most subject to the attacks of the Sty lops, for in¬ 
stance the labialis, convexiuscula, picicornis, Afzeliella, 
nigro-anea , Trimmerana, Gwynana, etc. The whole of 
the third and fourth sections are splendid insects, espe¬ 
cially the fulva in the last. The comparative rarity of 
some results chiefly from an exceedingly local habitat. 
Many of the species may be found everywhere where in¬ 
sects can be collected, consequently, all over the United 
Kingdom. In all the three seasons of the year, which 
prompt animal life, some of the species may be collected, 
and the flowers they chiefly prefer are the catkins, espe¬ 
cially of the sallow, the early flowering-fruits, the hedge¬ 
row blossoms, the heath, the broom, the dandelion, chick- 
weed, and very many others.

* This insect was first captured by me, and with this, my manuscript 
name, attached to it, it was distributed to entomologists with an un¬ 
sparing hand. The ordinary courtesy of the science has been, for the 
describer, when not the capturer, to adopt and circulate the original 
authority, and not to appropriate it. Similar buccaneering has been
