iEgeriidae 
Genus ALCOTHOE Henry Edwards 
(i) Alcothoe caudata Harris, Plate XLVI, Fig. 6, $. 
The larvse bore in the roots of various species of clematis^ 
The insect is widely distributed, occurring from Canada to Florida, 
and westward to the Mississippi. The moths come out in April 
and May in the South, and from June to August in the North. 
The larvae hibernate in their galleries in various stages of growth. 
Genus SANNINA Walker 
(i) Sannina uroceriformis Walker, Plate XLVI, Fig. 7, $. 
Syn. quinquecandatus Ridings. 
The larva feeds on the tap-root of the persimmon ( Diospyros) 
at a depth of from eighteen to twenty-two inches under the 
ground. The species occurs from Virginia to Florida, and west¬ 
ward as far as the food-plant ranges. 
Genus PODOSESIA Moeschler 
(1) Podosesia syringae Harris, Plate XLVI, Fig. 17, ?. 
Syn. longipes Moeschler. 
The larvae feed on the ash and the lilac. They tunnel their 
passages straight into the wood for many inches. They cut their 
way out almost to the surface just before pupating, leaving only 
a thin layer of fiber to close the end of the gallery; this is broken 
through by the emergent pupa as it comes forth from its cocoon, 
and then the pupal envelope is split and the perfect winged insect 
appears. The moths are on the wing in western Pennsylvania 
in June, and are to be found on the blossoms of Syringa. 
Genus MEMYTHRUS Newman 
(1) Memythrus tricinctus Harris, Plate XLVI, Fig. 14, $. 
The larvae infest the small trunks of willows and poplars. 
The moths appear in the latter part of June and the beginning of 
July; the caterpillars hibernate in their galleries. Transformation 
occurs in a tough cocoon located at the N outer end of the gallery. 
The species is found in New England and the Middle States, 
ranging westward as far as Ohio and Michigan.
