Tue cighth family of Micro-lepidoptera, of the sub-division Tineina, is that of the Gracilariide. The 
insects grouped in this family are distinguished from the neighbouring group of Argyresthide Wy their position 
when at rest. In direct contrast to the last named group of insects, the Gracilartidw pose themselves when at 
rest with the head considerably raised from the object upon which they are settling. Many of the species are 
very common, especially the pretty insect forming my illustration of the genus Gracilaria, which is extremely 
abundant in gardens in all parts of the country. With regard to their period of appearance, the group in general 
being double-brooded, the first brood of the year appears in summer, and the next brood passes the winter in 
the chrysalis state, emerging in the first genial weather of the earliest days of spring. Some few, however, like 
G. stigmatella, appear at the close of autumn, the later specimens appearing again in spring, after a season of 
hybernation during the severe winter months. There are three genera in this group or family, containing col- 
lectively twenty-seven species. Three species of Gracilaria ave considered rare -—G. stramincella, G. Ononidis, 
and @. imperialella ; and of Ornizx Devoniella only one British specimen has been taken. 
The genus Gracilaria. The insects assigned to this genus have the head without tuft, the labial palpi 
pointing upwards, the second joint being scaly, but without ‘‘ pencils” of hairs ; the terminal joint is pointed. 
The front wings are rather lance-shaped, and the fringes of both pairs of moderate depth. There are sixteen 
British species.
