Notes on White Mountain Noctuidae. 



The number of species of Koetuidae taken on the excursion 

 of our Club at Mt. Washington was very small in comparison 

 with that which is known to occur there, and this poor suc- 

 cess was mainly due to the difficulties which rendered almost 

 impracticable the Use of " sugar " and "light" in capturing 

 them. However, of those secured, some Were new to science, 

 many were rare, and all deserve mention. Particular interest 

 attaches to the distribution of the species which are peculiar to 

 the mountain fauna, and as, fortunately, many of these were 

 taken in the pupal state (through the kindness of the coleopte- 

 rists of the expedition), we are able to fix beyond question 

 their true habitat and the feeding place of their larvae. 



The notes attached to each specie's show that those of which 

 two or more specimens were captured were found indifferently 

 over the upper part of the mountain, and that therefore the 

 presence of two distinct fauual areas above the tree line was 

 not indicated,, at least for the family to which our observations 

 are confined. 



The great preponderance of the higher genera will be no- 

 ticed, and this proportion holds good in the north temperate 

 countries' of Europe and Asia as Well as America ; the lower 

 forms appear more numerously as the climate becomes warmer, 

 attaining their greatest development in the tropics. 



The following is a complete list of the species : 



PseudAhyatira eymatophoroides Guen. Two specimens of the 

 typical form were taken at sugar in the Glen ; one showed a 

 marked approach to the var. expultfix Grote, which was com- 

 mon in the same locality, and also near the Half-way House, 

 from July 3 to 10.
