Tue Fifth Family of Rhopalocera, or Butterflies, is that of the Hesperidw, contaiming a 
small group of insects, which by the structure of the antenne, and other characteristics, form a 
natural link between the last group of Butterflies and the first group of Moths. The Iesperida 
have the head remarkably broad, and the antennz inserted on each side, instead of being very 
near together as in other Butterflies. Some of the species also carry their wings horizontally 
when in repose, after the manner of Moths. The Caterpillars have the head large, as in the 
perfect insect, and they live in rolled leaves, in the manner of certain Moths ; and they also re- 
semble them in forming a slight cocoon, which is rarely the habit of the larvee of true Butter- 
flies. There are four British genera, containing seven species. All these are of comparatively 
small size, and have generally a jerking motion in their flight ; having thence received the name 
of “skippers,” by which they are popularly known to collectors. 
The genus Pyrgus. The antenne of this genus have the club gradually formed, but not 
hooked at the tip like some others. The wings are rounded, have deep chequered fringes, and 
are deflexed in repose. The Caterpillars are leaf rollers, and the Chrysalides are formed in a 
slightly webbed cocoon within the curled leaf that has served as the abode of the Caterpillar. 
There is but one British species. 
Pyrgus Alveolus (the Grizzle, Nos. 1 to 6). This is a common insect, especially in and near 
woods. The Caterpillar feeds most commonly on the wild Raspberry (Bubus Idwus) in April, 
and again late in the summer, and is to be found within rolled leaves held together by a web. 
It also feeds on the Teazle (Dipsacus fullonum). The perfect insect appears in woods and shady 
lanes in May and August. It has recently occurred in great abundance at Brighton, Bristol, 
Epping, and other places. 
There are several rather curious varieties of this species, the most permanent of which is 
one in which the white marks towards the tips of the fore wings run into one great irregular 
patch leaving only the veins dark, while in the hind wings the white marks are smaller and 
more obscure. This variety is said to be pretty constant in the forest near Bewdley, Worcester- 
shire, and occurs occasionally in many other localities more irregularly and more sparingly. 
The genus Wisoniades. In this genus the antenne are rather longer and more slender than
