206 HAUSTELLATA. — LEPIDOPTERA. 



Pale yellowish or rufescent, with the anterior wings thickly but very irregularly 

 marked with transverse slender ustulated streaks, the base, a fasciseform cloud 

 behind the middle, and a portion of the hinder margin brownish, towards 

 the anal angle an ustulated-purplish blotch ; posterior wings paler, with the 

 base immaculate, the hinder margin with a few ustulated streaks condensed 

 into an ustulated-purplish blotch at the anal angle ; cUia rufescent, purplish 

 towards the anal angle of all the wings : head, antennse, anterior portion of 

 the thorax, and apex of the abdomen ustulated, and sometimes tinged with 

 purplish. 



Caterpillar greenish-brown, with some black spots, and a lateral line, yellow in 

 the middle, and brownish behind : it feeds on the oak, Ume, &c. : — the pupa 

 is brown : — the imago appears towards the end of June. 



Not very common : taken occasionally in Richmond-park, and at 

 Coombe and Darenth Woods ; also at Dover and in Devonshire.

Genus CXCV. — Pellonia, Duponchel. 



Palpi obtuse, not projecting beyond the forehead : maxillcB long. Antennce very- 

 long, bipectinated in the males, simple in the females : wings entire, aU tra- 

 versed by a narrow band towards the centre of the disc, the band often 

 dividing into two hues: legs very long. Larva with ten legs, long, slender; 

 pupa slender. 



Not having had an opportunity of examining an insect of this 

 genus with reference to its generic distinction, I have been com- 

 pelled to depend upon DuponcheFs * abridged character. 



• It is necessary to observe, that in referring to Duponchel, I do so from a firm 

 conviction of the propriety thereof, consequent upon the following passage in 

 his 7 th volume : " Prejudiced in favour of Treitschke's arrangement of the Pha- 

 Isenidce, / had intended to adopt it unaltered in this work (the Lepidopteres de 

 France, commenced by his friend Godart, and carried on so praiseworthily by 

 Duponchel, in consequence of the lamented death of the former) ; but on 

 applying it to my own collection, I found that the author comprehends a host of 

 species in his genera which do not possess the characters assigned respectively to 

 them." From which it is manifest that he, and not Godart, as elsewhere so repre- 

 hensibly quoted, to the confusion of the student, is the proposer of the various 

 generic names to which I have referred in the Geometridas : the same remark 

 will apply to the references to Treitschke, he having in like manner undertaken 

 the completion of the Schmetterlinge von Europa of his friend Ochsenheimer.
