DESCRIPTION OF THE SPECIES. 



The moth which produces the greenhouse leaf-tyer is a member of 

 the family Pyraustidse, superfainily Pyraiidina, and was first recognized 

 and described from this country in 1S51 (Guenee, Deltordes et Pyra- 

 lites, p. 398). It is an inconspicuous little pale reddish-brown species 



with a wing expanse of about 



' ■■•-■■ 



three-fourths of an inch. 

 The fore-wings are light clay 

 brown in color, suffused 

 with a slightly darker red- 

 dish or ochreous brown, the 

 serrate blackish lines with 

 which they are ornamented 

 forming the pattern shown 

 in the accompanying illus- 

 tration (fig. 1, a). The hind- 

 wings are gray, becoming 

 light brownish toward the 

 terrnen, and with two discal 

 Both wino-s are bordered with a row

spots, the costal one prominent, 

 of small well-defined black dots. 



The description of the moth by Mr. A. R. Grote. which appeared 

 in 1877 under the name of Botis harveyana (Can. Ent., vol. IX, p. 

 104), is copied herewith for the further identifi- 

 cation of the species: 



A small species more slender than communis, 1 with pale, 

 brown primaries, the exterior line fine, blackish, obsoletely 

 denticulate, rather suddenly drawn in at vein 2, thence 

 back again and angulate before the margin. Outer spot 

 large, annulate. Inner spot obsolete. Before the fringes, 

 which are faintly interlined with pale and are discolorous, 

 there is a distinct sinus of dark points. Hind-wings paler 

 than primaries, washed outwardly with the same brown 

 as primaries, with a distinct discal dot and median line. 

 Beneath more ochreous, with the discal dots double on 



hind-wings; a common exterior line; on the primaries the veins are partially darker 

 marked; terminal points very distinct and continuous. Plead, palpi, and thorax 

 above pale-brown, beneath concolorous with under surface of wings glistening. 



Dimensions: Fore-wings, 17-20 mm ; hind-wings, 11.5-17 111 " 1 : length 

 of body, 7.5-10 mm . 



The venation and the shape of the head and antennae is about as in 

 P.ferrugalis shown in figure 2. 



The moth bears a strong super lie ial resemblance to the common
