C1LISSA. 211 



the Rosce 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 Stylops, for in- 

 stance the labialis, convexiuscula, picicornis, Afzeliella, 

 nigro-ainea, 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
