/Egeriidae 



Genus ALCOTHOE Henry Edwards 



(i) Alcothoe caudata Harris, Plate XLVI, Fig. 6, 6. 



The larvae 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. qitinqitecaitdatus 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 Mceschler 

 (1) Podosesia syringae Harris, Plate XLVI, Fig. 17, ?. 



Syn. longipes Mceschler. 



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 outer end of the gallery. 

 The species is found in New England and the Middle States, 

 ranging westward as far as Ohio and Michigan. 



(2) Memythrus polistiformis Harris, Plate XLVI, Fig. 11,
