GEOMETRID NOTES. 



BV HARRISON G. DVAR, WASHINGTON, D. C. 



In Can. Ent. for April, 1907, Mr. Taylor has a note on Euchoeca 

 perlineata, Pack. It appears to me that he is clearly in the right in his 

 conclusions, for in any case where published descriptions and figures con 

 tradict an alleged type, it is the evidence from the publication that must 

 prevail. Types, even when labelled by the author himself, cannot take 

 precedence over a published description, except in cases where an error 

 of observation can be demonstrated. 



I think it has not been put on record that Cosymbia albocostaliata, 

 Pack., is a Noctuid. It will be probably best placed in Pleonedyptera^ 

 Grote, and, to follow Professor Cockerell's recommendation (Can. Ent., 

 XXX IX, 136, 1907), I hereby provisionally nominate it Pleonectyptera 

 albocostaliata. There is a specimen in the Neumcegen collection in the 

 Museum of the Brooklyn Institute, and two in the U. S. National 

 Museum, the latter collected by Mr. YV. F. Fiske at Tryon, North 

 Carolina. I have not seen the type, but the specimens agree perfectly 

 with Packard's figure. 



LAERTIAS (PAPILIO) PHILENOR (LINN.EUS). 



BY A. A. GIRAUL1\ BLACKSBURG, VA. 



On June 2olh, 1903, at Blacksburg, Virginia, a colony of the larvs" 

 of this species was obtained from vines of the Dutchman's Pipe 

 ( AristolocJiia) growing over the ruins of an old stone building. The 

 majority of them were nearly full-grown, and the whole colony was placed 

 in a breeding cage and supplied with food I offer the following notes at 

 the risk of repeating : 



The Larva. — Nothing especially important was noted concerning the 

 cater[)illar, excepting a variation in the number of spots in the dorso- 

 lateral line. This line of orange spots or tubercle areas consists usually 

 of a tubercle on the first abdominal segment just above the spiracle, and 

 four tubercle areas, one on the 4th, 5th, 6th and yth abdominal segments 

 resj^ectively, and all about the same size, but varying somewhat in colour. 

 In the case of one larva, an additional area was present on the 8th 

 abdominal segment, l)ut was faint; in another larva, after the first segment, 

 the areas began on segment 3 instead of the 4th, continuing to the 7th 

 (inclusive). Two larvie were found with the si)Ots running from the 3rd 

 to the 8th abdominal segments, but those on the 3rd and 8th segments 

 were faint. Apparently, when there are more than the usual number 

 jiresent the additional ones are faint. All of the larvte were in the last
