sliade line below costa and some metallic scales below median vein. Middle of the 

 wing mottled, grayish, enclosing two metallic discal spots edged with black, super- 

 posed ; below them two faint blackish lines to internal margin. Apical portion of the 

 wing taken up with a wide circle of dusky and orange scales enclosing a series of 

 metallic points edged with black. The space enclosed by the circle, near the margin, 

 is gray and mottled like the middle of the wing. The metallic spots have a violet or 

 green reflection. The circle is twice cut by oblique orange stripes, over the sub- 

 costal nervules and over the median nervules, in opposing positions. Edee of the 

 wing dusky, fringes dark. Costal edge with two white dots beneath, wide apart. 

 Hind wing blackish ; beneath crossed by a white sub-terminal band, and another 

 before the middle of the wing. Length of fore wing 5 to 6 mm. 

 Hab. Illinois. 



The larva of this species is described by Mr. Coquillett as follows : 



"Body thickest at the middle, tapering towards each end, pale green ; a dark 

 colored dorsal line; piliferous spots and cervical shield green; head small, nearly 

 horizontal, 'pale green, with a black dot on each side near the jaws, and usually with a 

 black dash on each side near the junction of the head with the first segment ; venter 

 pale green, unmarked ; 16 legs; length, 13 mm. Lives in communities on Silphium 

 integrifoliiim in nests formed by fastening the terminal leaves together with silken 

 threads. Found June 19 ; imagoes July 2." 



Mr. Grote prefaces the above with the following : " Mr. Coquil- 

 lett has communicated to me specimens of a C/wrentis which he has 

 reared, together with a description of the larva. The species appears 

 to be new and is considered by Professor Fernald to be distinct from 

 pretiosana.'''' Mr. Grote concludes his description with the state- 

 ment: "a distinct but allied species of Choreutis has been collected 

 by Mr. Hy. Edwards in California (Sierra Nevada)." 



The following is Dr. Hulst's description of Chalcoela gennualis, 

 which is manifestly the same as Mr. Grote's species. I have not been 

 able to find Dr. Hulst's types.* 



" Expands 15 mm. Head brown, palpi brown, fringe in front ; thorax and 

 basal portion of fore wings rich golden brown ; fore wings beyond light ochre, with 

 fuscous shadings ; margin yellowish brown, fringe black ; near middle of wing, 

 also just within indicated extramedian line, and also on subterminal space at middle, 

 is a velvety black spot, the three being in a row ; a fine black line runs from costa to 

 middle spot ; there is also midway along costa a faint subcostal black spot ; each of all 

 these sppts surrounds a few bright golden metallic scales ; there is also a line of metallic 

 gold basally along costa ; hing wings nearly even, fuscous ; beneath, fuscous with a 

 golden tinge, a white spot on costa at beginning of outer line, which is indistinct; an 

 outer cinereous line on hind wings ; all margins with whitish lines ; fringes fuscous. 



* Mr. W. Beutenmuller informs me that Hulst's type of C. gemmalis is in the Hy. 

 Edwards collection, American Museum of Natural History, and he has compared it 

 with a specimen labelled C. silphiella Gr. , and finds them identical.
