corylieUa Cliatno. (Ciu. Qr. Jr. Sc, II, 242), which Chambers, in the Index (Bull. U. 

 S. G. G. Surv., IV, 150), refers with a "f " to Menesta tortriciformella, is without doubt 

 another name for this species, and consequently the genus Hyale sinks as a synonym 

 of Menesta. 



IDE. 



The genus Ide is distinguished by having veins 7 and 8 of the fore wings separate, 

 •2 and 3 from a point, or from a short common stem, and 4 very close to the base of 2 

 and 3 ; in the hind wings 6 and 7 arise from a common stem. 



Ide lithosina Z. 

 Cryptolechia lithosina Z. 

 =^Uarpalyce iortricella Chamb. 



I have several specimens of lithosina Z. ; some from Texas (Belfrage), others from 

 Florida (Morrison), and one from Boll's collection. They vary in the ground-color of 

 the fore-wings from bone white, as described by Zeller, to yellowish or straw-color, 

 as described by Chambers, and in the presence or absence of one, or sometimes two, 

 brownish dots at the end of the discal cell. In one specimen these are quite conspic- 

 uous. A careful examination of the genital appendages shows that these forms are 

 not specifically distinct; the uncus is single, with a long narrow stem beyond the 

 dilated base; overarched and spatulate at the apex, the end of the spatulate being 

 notched; the lateral claspers are scarcely more than half the length of the uncus; 

 also somewhat narrowed at the base, their ends dilated and notched posteriorly, the 

 upper lobe being rounded at the apex, the lower slightly longer than the upper, and 

 acutely triangular. 



Ide osseella sp.u. 

 Antennw, pale bone-color. 



Read and palpi, pale bone-color, the latter somewhat darker on the second joint. 

 Thorax, bone-gray, slightly darker than the head. 



i^ore-Hun^'s, shining, uuicolorous bone-color, with scarcely paler cilia, along the base 

 of which is a very slender almost undistingnishable grayish li.ie; at the end of 

 the disk is a reduplicated bone-gray spot, the larger portion of it being above the 

 smaller, with which it is sometimes confluent. Under side, very pale bone-gray. 

 Neuration: The veins are all separate, except 2 and 3 which in one specimen are 

 from a common point, in the other from a shore stem. 

 Hind-icings, pale, shining bone-gray, with scarcely lighter cilia. Under side,veTy pale 



bone-gray. 

 Abdomen, pale shining bone-gray. 



Legs, pale bone-gray, the posterior tarsal joints with the slightest tinge of ochreous. 

 Exp. ah, 24°"". 



Habitat, California. (Two females from the Zeller collection.) 

 Type, 9 , Mus. Wlsm. 

 This species is apparently allied to lithosina Z., but it is of larger size. 



Ide vestalis Z. 

 Cryptolechia vestalis Z. 

 ■=Harpalyce albella Chamb. 

 Zeller in describing vestalis (Ver. Z.-b. Ges. Wieu, XXIII, 247), says that it is closely 

 allied to albella, but as Chambers' Harpalycc albella was not then published, it is 

 obvious that his reference must have been to a si^ecies described by himself, un- 

 der this name, received from Surinam.
