grass lanes, or by rivers and pools in summer. Some of the spe- 

 cies are day fliers. 



Tortricidce. (Leaf-rollers.) These are small, broad-winged moths, 

 which at rest fold their wings, roof-like, over their bodies, fiq. is. 

 in the form of a triangle, (as in Pig. 18.) They are abund- 

 ant in June and July, in low bushes, herbage, or on leaves 

 of trees, where they can be swept by the net. The larvae 

 are rather thick greenish caterpillars, which roll up leaves ; 

 their work can thus be easily detected. When disturbed they wrig- 

 gle out of the other end of their domicile, and let themselves down 

 by a silken thread. Others feed on buds and flowers, such as Loxo- 

 tcenia; while another tortrix Garpocapsa pomonella, the " Codling 

 moth," lays its eggs in the plumage of the young apple, and in 

 the fall is found as a white fleshy grub in the core. 



lineidas. These are the smallest of moths, and arc known not 

 only by their minute size, but by their narrow wings, often falcate, 

 or pointed acutely in both pairs, and edged with a long fringe of 

 exceeding delicacy. The maxillary palpi are greatly developed, 

 while the labial palpi are of their usual size, and are sometimes 

 recurved as in the Pyralidae. ^ 



Granibus and its allies have long palpi and obleng wings, gene- 

 rally white and buff yellow, sometimes ornamented with golden 

 spots. They fl}'- in grass in great abundance, resting on the spears 

 with their heads down. To this group belongs the Bee moth, ( Gal- 

 leria cereana) which as a larva eats wax. There are two broods in 

 a season. 



Hijponomeuta has long maxillary palpi, and very long antennae, 

 closely resembling some of the smaller Phryganids. The Tineids, 

 generally, are moths of rare beauty. Tlie family is one of great 

 extent, and the species are very destructive to vegetation, and 

 have innumerable modes of attack. Thus, Tinea vestianella, the 

 clothes-moth, and allied species, construct a case of the fibers they 

 eat, and bear it about for their protection. In June the moth 

 appears and lays its eggs. Tinea granella make a silken web of 

 the grains they devour. Another species, 

 still more destructive in gr^iaries is the 

 Angoumois moth, {Anacampsis cerealella, 

 Fig. 19,) which secretes itself within the 

 grain, devouring the mealy substance. 



Alucifw. This is a family comprising a 

 few species whose wings are divided into numerous delicately
