them with a note of doubt, he subsequently reverts to my original statements, 

 because he chooses to overlook my last published remarks on the doubtful 

 points, and in no instance has he admitted more misstatements than under 

 the present genus, which alone induces me to refer to them here, in order to 

 put his readers on their guard as to his usual practice, as well as injustice 

 to my own. 

 In the place above referred to Mr. Curtis gives Ph. Ge. aversata of Linn^ for 

 the type of Acidalia: this, however, is Treitschke's 8th species of Idaea, — 

 the type of his Acidalia being Geo. ochreata of Wien. Verz. I therefore 

 continue my own appellation. 



Page 311. Ac. aversata. Mr. Curtis says, "the other figure referred to by 

 Mr. Stephens is an Eupithecia ! " If he had looked at the plate referred to 

 (Hubner, pi. 75. f. 388) he would have found that it was one of the very 

 numerous errors of a similar description committed by Hubner himself by 

 transposing his own numbers: my reference is Geo. aversata, fig. 388. — 

 now the Eupithecia is fig. 389. (Eu. pumillata), the numbers being trans- 

 posed in Hubner's plate.

Wings pale ochraceous-brown, anterior with the costa red ; a reddish-brown 

 fascia in the middle, waved on its margin, and with a black dot within 

 towards the centre; behind this fascia are two somewhat parallel waved 

 pale fuscous streaks, and a darker line on the extreme edge : posterior wings 

 somewhat similar, but the reddish-brown fascia is more basal, and the black 

 dot is placed beyond its outer edge. 



Taken by Mr. Curtis in the Isle of Portland in June.

 of the twenty-three species of Lepidoptera that were first discovered by us 

 (Mr. D. and himself) in Scotland in the course of a few weeks."*

 doubt in my Catalogue.

• In July 1827, I found at Ripley (within twenty-five miles of London) no 

 less than sixteen species of Lepidoptera that were either entirely new, or not 

 known to inhabit this country, exclusively of taking about one-fifth of all our 

 known insects in the same period, as noted in Mandibulata, vol. i. p. 72.
