itself is doited with little black spots. The moths should be looked for about 

 maple trees. Populetella I have never taken. Mongella expands about 

 seven lines, it is a little reddish ochreous coloured moth, with a not very dis- 

 tinct triangular shaped mark on the costa, just a little paler than the ground 

 colour of the wing. It may be found about alder trees, in June and Septem- 

 ber; the larva rolls up the leaves lengthwise in May and July. It is a 

 generally distributed species. 



Turning now to the second group of the genus Gracilaria, we find the 

 smaller species, viz. those under live lines — represented in September by three 

 species. The first of these, phasianipennella, is the largest of the three, and 

 is indeed, scarcely smaller than semifasciella. It has sinning brown fore- 

 wings with white or whitish spots, two of which are on the inner margin, and 

 three on the costa : sometimes these last are very indistinct. The moth may 

 be obtained by sweeping herbage, in the localities where it occurs. The larva 

 feeds in August and early part of September, on biting pericaria (Polygonum 

 kydropiperj and sorrel. It has a yellowish-brown head with four black spots, 

 and a greyish coloured body, and lives in rolled up sprigs of its food plant. 

 The other species are auroguttella and ononiella. The former is a dark 

 bronzy grey moth, with four golden yellow spots on its forewings. It is 

 double brooded, the first brood appearing in May from larvse feeding in the 

 preceeding September aud October, the other emerging in July from larvae 

 feeding in June. These larvse live in cones on leaves of St. John's Wort; 

 they are whitish green, with pale brown heads. Ononiella is a small dark 

 brown moth, with silvery spotted wings. It may be obtained sparingly by 

 sweeping clover throughout the summer. 



Besides the above, two other species of the family Gracilariida may be 

 looked out for by the micro -lepidopterist in September and October. They 

 belong to the genus Coriscium, the moths belonging to which have the second 

 joint of their labial palpi furnished with a projecting tuft of Lairs. Cuculi- 

 pennetta makes cones on privet leaves in August, from which the pale grey 

 fuscous-clouded moth emerges in September, and hybernates in November, 

 reappearing the following spring, citrinella is a sulphur coloured moth, which 

 occurs in the New Forest and other places in the autumn, and like cuculi- 

 pennella hybernates in the winter. Besides these two, the greyish-brown 

 Brongniardella occurs about oak trees, from July to October. 



There are one or two other tineites occuring in the autumn, such as 

 Laverna decorella, Phyllocnistis sufusella, and P. salignella, but I have such 

 a long list of larvae to mention, that 1 am unable to say more about the 

 imagines. 



Biurnea fagella is sure to be found between united beech, and other leaves
