obsolete), thus destroying the analogy evidently existing between Papilio 

 and Pier is. As, therefore, (so far as I know), no butterfly has more than 

 12 nervures, and these nervures are not always analogous when numbered 

 straight on, and since it has been customary to call the costal nervure 12 

 and the two nervures usually arising from the top of the cell 10 and 11, 

 I have found it necessaiy to give the supplementary cell at apex of wing 

 another name, and I call it 8a. to prevent confusion. This is all I have 

 to offer as an excuse to those gentlemen whose susceptibilities I may have 

 offended by my vagary. I am very sorry, but at present I cannot even 

 promise not to offend again.

NEW SPECIES OF NOTHOCHRYSA. 



BY ALEX. D. MACGILLIVRAY, ITHACA, N. V. 



Since 1861, the date of Hagen's Synopsis, only three additional 

 species of Chrysopidse have been recorded from the United Stales — one 

 from Florida, one from Texas and one from California. During the past 

 summer T received a short note from Mr. A. P. Morse, of VVellesley, 

 Mass., enclosing a i^ff specimens of Chrysopidte which he thought might 

 prove new to our collection. When the specimens were studied they 

 were found to belong to the genus Nothochrysa and probably new. 

 Upon communicating this fact to him he requested me to describe the 

 species and sent all his material, together with some other miscel- 

 laneous Chrysopidse, among which was found another new species of 

 Nothochrysa. The collection also contained specimens of Chrysopa 

 upsilon, Fitch, and Chrysopa chi, Fitch ; the latter was unknown to Dr. 

 Hagen when he wrote his Synopsis, and is apparently rare. 



The American species of Nothochrysa can be separated by means of 

 the following table : — 



A. Antennae with the second segment annulated with 



black ajnmlata. 



A. A. Antennas with the second segment not annulated with black. 



B. Antennae white, prothorax green, size large phantasma, 



B. B. Antennae and prothorax black, size small calif or7iica, 



Nothochrysa annulata, sp. nov. — Antennas nearly or quite as long as 

 the wings, basal segment white, immaculate, second segment ringed with 

 black, remaining segments yellowish ; head ferruginous, marked with 

 black, as follows ; Six dots on the vertex, one at each corner of an imacin-
