Tur sixth family of the sub-division Tineina is that of the Glyphipterygide. The insects comprised in 
this family when in the perfect state have the head generally smooth, and the maxillary palpi so short as to be 
scarcely perceptible. The fore wings are either oblong or elongate ; the hind wings sometimes rounded at the 
tip, but in other species very narrow and pointed. Their time of flight is diurnal. In the Caterpillar state they 
have generally sixteen legs, but in some species the larvie are nearly maggot-formed, and without any perceptible 
feet. Many of the species are gaily coloured and attractive insects, though their small size causes them often to 
be overlooked by young collectors. Most of them are common, though two of the species, Acrolepia Betulella and 
Roslerstammia Pronubella, are very rare. There are twenty-two British species comprised in the eight genera 
belonging to this family. 
The genus Acrolepia. The insects assigned to this genus have the extreme crown of the head rough. The 
labial palpi are thick, but have the terminal joint pointed. The fore wings are generally elongate, the hind 
_ wings being sometimes rounded and sometimes pointed at the tip. The Caterpillar has the full complement of 
sixteen legs, and feeds in the interior of leaves. The Chrysalis is formed in a cocoon of open network. There 
are four British species. 
Acrolepia granitella (the Granitellian Acrolepia, No. 1). The Caterpillar of this species is pale yellowish 
green with a dark line along the back. It feeds in June and July in the leaves of Inula dysenterica. The 
perfect insect appears in July and September. It has been recently observed in great abundance near 
Scarborough, and Chudleigh. 
The other species are A. Perlepidelia, having the fore wings orange suffused with black and variegated with 
pale yellow markings; A. pygmeana which has the front wings marbled with white and brown; and 4. 
Betulella, which has the front wings brown mottled with darker brown. This last species is extremely rare. 
The genus Roslerstammia. The insects assigned to this genus have the antenue thick and long, and the 
labial palpi short and drooping. The front wings are of moderate length and breadth, and the hind wings 
rounded at the tip. The Caterpillars of this genus, as far as the indigenous species are concerned, remain 
undescribed. There are two British species, one of which is, however, so rare, as to render it doubtful as a 
native insect. 
Roslerstammia Erelebella (the Brown Copper, No. 2). This pretty insect appears in May and June. It 
has been observed recently in some plenty at Bristol, and its presence has also been recorded at Worthing and 
other places. 
The other species, R. Pronubella, has the front wings of shining golden green, rather yellowish along the
