Three species of Halesidota may be mentioned, viz., H. Maculata, Harr.; H. Tes*el- 

 ■aris, Hb., and H. Caryce, Harr. The caterpillars of these are hairy, and are distinguished 

 by having long pencils of black or white hairs upon certain segments. They pupate in 

 .hairy cocoons, under stones, loose bark, or other shelters.

Orgyia /eucostigma, Sm. Abb., the white-marked Tussock moth (Figure 25), has a 

 caterpillar somewhat similarly clothed, but with different ornamentation and colouring 

 •See Figure 26. s

Oedemasia concinna, Sm. Ab., is the moth whose larva is called the Red-humped 

 Apple-tree Caterpillar (Fig. 27). The larvae have been found by me to feed also upon 

 the willow. 



The web-making caterpillars of Clisiocampa and of Hyphantria textor, Harr., which 

 by their unsightly webs and omnivorous habits make themselves most unwelcome intruders 

 in orchard or grove, also attack the willows. 



Xyleutes Robinice, Harris., is said to attack the willow as well as the oak, locust and 

 maple. The larvse (which are pale greenish-white, and attain a length of two inches or 

 more), instead of feeding upon the leaves, as do the preceding species, are true borers in 

 the trunks or lai'ge limbs of trees, and, from the size of the burrows excavated by them, 

 work great injury to the trees they infest. 



The next large group of moths is that of the Noctuidee, the species of which, while 

 more numerous, are also smaller and less conspicuous in their ornamentation. 



Apatela oblinita, Sm. Ab., the Smeared Dagger moth, is a modestly coloured moth 

 (Fig. 28, c), but the caterpillar, which feeds also on apple, grape, etc., is very gaily coloured 

 (Fig. 28, a), with bright yellow and crimson bands and spots upon a black ground. It 

 pupates as shown in Fig. 28, b, in a thin cocoon attached to the stems of grass, etc., or 

 loosely enclosed in a few leaves. 



Apatela Americana, Harris, the A luerican Maple moth, whose larva feeds on maple, 

 elm, willow, poplar, etc., is a paler and somewhat larger moth than the preceding. The 

 caterpillar, when fully grown, is nearly two inches long. It is of a greenish black coour 

 covered with yellowish hairs, and having two pencils of long erect black hairs on the 

 fourth segment, and another on the eleventh.
