Family LIPARID^. 



These are the "tussock moths"; sombre gray or brown species ol 

 moderate size, with broad wings, broadly pectinated antennas in the 

 male, and long hairy fore-legs, which when at rest are stretched out 

 forward. In the genera "Notolophus" and "Hemerocampa," the latter of 

 which is now used for our species previously referred to "Notolophus," 

 the females are wingless. The caterpillars are brightly colored and have 

 truncated dorsal tufts or brushes of hair and long pencils at or near the 

 extremities. 



HEMEROCAMPA Dyar. 



H. definita Pack. Lake Hopatcong (Pm) ; Millburn eggs only (Gr) ; 

 Ft. Lee (Bt) ; and undoubtedly occurs throughout the northern part 

 of the State. The larva is quite a general feeder. 



H. leucostigma S. & A. The "vaporer" or "White-marked Tussock 

 Moth." Occurs throughout the State in cities, towns and villages, 

 and is the most common of the caterpillar pests of shade trees. It 

 is rarely found in woodland or away from settlements, and it seems 

 to be abundant and troublesome in proportion to the dominance of 

 the sparrows, which do not eat the larvae and prevent the existence 

 of birds which might do so. The female is wingless, and when she 

 emerges from the pupa crawls on her cocoon and lays a mass of 

 whitish eggs, which are then covered with a snow white, frothy mass 

 that becomes hard and brittle after a brief exposure to the air. 

 There are two broods in the southern half of the State and only one 

 in the north. In Newark there is a partial second brood only. In 

 any case the eggs winter unhatched, and as they are conspicuous, 

 gathering and destroying is a good way of checking the species on 

 small trees. The young larvae succumb readily to the arsenites; but 

 the older caterpillars are quite resistant.
