folds black dotted. Thoracic feet faintly brownish. The larva rests on 

 the edge of the leaf, curling its body more or less downward. 



Nematus dorsiviitatus, Cresson. 



Larvae on poplar at Jefferson Highlands, N. H. Identical with 

 Nemattis 7ne7idicus, txct^i in size; width of head 1.7 mm. The dark 

 spottings on the head fail to separate these species, for in these most 

 recent specimens of JY. dorsivittatiis they are about as distinct as in 

 N. mendiais. The anal prongs pointed, black tipped. Larva described, 

 Trans. Am. Ent. Soc, XXII., 303. 



Cladius pectinicoriiis, Foucr. { = isomera, H.a.rns.) 



Larvae on wild rose in VanCortlandt Park, N. Y. Five stages 

 observed with width of head .3, .5, .7, i.o, 1.4 mm. No ultimate stage. 

 The larvae are already adequately described. 



AGRONOMA AGAIN. 



BY JOHN B. SMITH, SC. D. 



In 1895, according to Mr. A. R. Grote, "the European type of 

 Agronoma seems certainly to be vestigialis." This species was declared 

 to be congeneric with the American species classed by me as Feltia, and 

 the latter genus was dropped in favor oi Agronoma., and Mr. Slingerland 

 was scolded because he had adopted the generic name used by me. In 

 the January (1896) number of the Can. Ent. I pointed out for Mr. 

 Grote's benefit, and also for the information of American students, that 

 there existed certain points of structural difference which had escaped 

 Mr. Grote's examination, which made the declared type of Agronoma a 

 member of the genus Agrotis as restricted by me, the latter genus being 

 based upon the very species which Mr. Grote said was its type. As the 

 result of this paper, it has become much less "certain" to Mr. Grote's 

 mind that vestigialis is, after all, the type of Agronoma, and on recon- 

 sidering the matter, it seems to him that crassa had better be considered 

 the type. Mr. Grote states, in the June number of the journal of the 

 New York Entomological Society: "I have examined here, in the 

 Roemer Museum, specimens of crassa. The fore tibiae are heavily armed ; 

 the front is roughened or tuberculate ; the male antennae are pectinate. 



It is therefore a Feltia " "It follows that the type of Agronoma 



must be changed, and crassa, the first species cited, is then the type," It 

 is to be noted that Mr. Grote refers to the front as being " roughened or
