The larva works in Panicum clandestinum early in July; the mine begins at the 

 base of the leaf and runs to the tip and part way back before the enlargement 

 begins to be formed. 



Distribution probably general; moth in late July and August. 



New York(?); Pennsylvania; Ohio. 



6. SCHBECKENSTEINIA Hiibner 



(Clirysocoris Curtis) 



Rather similar to Epermenia and possibly related to it. Head similar; no 

 pecten; fore wing similar (fig. 220), with Sc much longer than 2d A, not dis- 

 tinctly falcate, but lanceolate; without dorsal tufts; all veins present; R 3 ending 

 just below apex. Hind wing with R running to just below apex and never stalked 

 with M r Hind tibiae with a single series of bristles above; palpi short, divergent. 



Egg of upright type. Larva with setse iv and v separated only in first stage, 

 then on one tubercle; setse i and ii glandular, as in some Pterophorids, adjacent 

 at base. Prolegs long and slender, with only 4 to 6 hooks in a circle at the tip. 

 Cocoon of regular meshes; the larval skin thrown out through a hole. Pupa incom- 

 plete; emerging from the cocoon; with segments 3 and 6 free, and 7 in male; with 

 heavy dorsal spines and recurved hairs on fifth to ninth segments of abdomen, 

 and small ones on the third segment also; spiracles on high cones; maxillary palpi 

 very small, dehiscing with legs; palpi and femur exposed; first legs touching 

 antennae at base; the others reaching tip of wings; prothorax minute; headpiece 

 larger. 



The genus curiously combines Yponomeutoid and Pterophorid characters, and 

 was for a time placed in the Pteropkoridae. . Meyrick puts it here, however, but 

 Spuler. in the Scythrididaa, with Epermenia. 



1. S. erythriella Clemens. Reddish fuscous, with a more or less distinct green- 

 ish brassy hue; palpi ochreous with a fuscous tip; fringes fuscous. Hind wings 

 reddish fuscous with concolorous fringes. 9 mm. 



August. Larva in July in fruit racemes of sumac. Strongly moniliform, with 

 raised tubercles: dark green, with rather small, pale brown head. Cocoon of large 

 meshes; pupa green; on outside of raceme. 



Distribution probably general. New York: Ithaca. Albany. 



2. S. feliciella Walsingham. Deep bronze brown; browner and darker than 

 8. erythiella ; palpi with dark third joint. 9 mm. 



This species was bred from Orthocarpus. The eastern record is very likely in 

 error for an aberration of 8. erythriella. 

 Pacific Coast; Hazelton, Pennsylvania. 



3. S. festaliella Hiibner. Fore wing light olivaceous and brown, with a slight 

 golden iridescence; contrastingly veined, with dark brown. 12 mm. 



April and May: July and August. Caterpillar green with brown head, on 

 Pviibus leaves, in a slight web; the cocoon as in 8. erythriella. 



Known from Massachusetts to western Pennsylvania and Michigan ; Europe. 

 New. York: Ithaca, Rock City. 



Family 27. ^GERIID^ 



(Sesiidm; Sphingidce, in part) 



Head rather small; body often stout; mostly smooth-scaled; some- 

 times with rather finer hair-scales; ocelli present; palpi moderate, 

 upturned often to vertex, normally smooth-scaled, without bristles. 

 Antennas usually fusiform, tapering to both base and apex, the terminal
