364 ANNUAL EEPORT OF NEW-YORK 



PLUM. LEAVES. 



circular lid, the moth coming from it the following Jul}'. Tills 

 moth is most readily distinguished by the fine prostrate curled 

 hairs covering its fo-re wings and arranged in regular waves run- 

 ning as it were from the base to the tip. Its body and legs are 

 also very hairy and at the tip of the abdomen is a tuft of long 

 soft hairs forming a bushy tail. It is of a straw yellow color 

 with the fore wings more or less dusky on the outer margin, and 

 the feet and orbits of the eyes black. The fore legs are often 

 black on their anterior side and sometimes the face is also black. 

 Width 1.20 to 1.80. I have never met with this in New- York 

 and it is omitted in the second edition of Dr. Harris's Treatise, 

 but it appears to be common at the south and west. The Spa?-- 

 shalli of Mr. Curtis can scarcely be distinct from this somewhat 

 variable species, and I suspect Mr. Stephens (List Brit. Mus.) is 

 in error in giving that as an Australian insect and that Boisduval 

 was correct in regarding it as North American. Mr. Westwood's 

 generic name Trichetra was published the year before Dr. Harris's 

 name Lagoa. 



American Vaporer moth. A slender pale yellow caterpillar, 

 its head and two little knobs on its back bright coral red. See

 the body of the tree early in spring. See No. 38.
