MELLISOPUS Riley. 



M. latiferreana Wlsm. Newark, VIII, at light, not common, but g. d. 

 (Dietz). 



DICHRORAMPHA Gn. 

 D. simulana Clem. New York, Pennsylvania and probably New Jersey. 



Family COSSIDiE. 



These are usually large moths, somewhat resembling the Sphinges in outline 

 but with much smaller head, weak, short palpi and an obsolete tongue. The 

 antennse are also short and weak in proportion to the size of the insects, though 

 in the male they may be pectinated for at least part of the distance. The legs 

 are comparatively short and weak and, while the insects seem robust enough, 

 they yet give an idea of helplessness and weakness, which is borne out by the 

 feeble flight of the gravid female. In venation they are primitive. 



The larvae are borers, living in the heartwood and they sometimes do con- 

 siderable injury. 



COSSUS Fabr. 



C. reticulatus Lint. Taken rarely by the Newark collectors. 



C. centerensis Lint. Rare near New York (Bt). The larva lives in the 



trunks of poplar and almost certainly occurs in northern New Jersey. 

 C macmurtrei Guer. This is in the same case as the preceding. The larva 



bores in oak. 



PRIONOXYSTUS (Sort. 



P. robiniae Peck. The most common of the species of this family and 

 generally distributed throughout the State. Mr. Davis finds it on Staten 

 Island in June and July ; Caldwell (Cr), Newark and Jersey City, VII, 13 

 in cop (Sb), Camden, VI, 6 (Kp), Ocean County in July. The larva 

 bores in the trunks of locust, willow, poplar, chestnut and oak ; but in 

 my experience prefers the latter. It is common near Philadelphia, and 

 in Ocean County a large proportion of the trees are attacked, becoming 

 " doated " and useless except for firewood. 



P. querciperda Fitch. Taken rarely by the Newark collectors ; VI, 13 (Sb). 

 The larva is said to attack oak and chestnut. 



ZEUZERA Latr. 



Z. pyrina Fabr. = aesculi L. An introduced species which has spread from 

 Jersey City for some distance northward along the Hudson and westward 

 to Elizabeth, causing serious local damage to shade and orchard trees. 

 It is strictly confined to the cities and their immediate vicinity where the
