which forms a diffuse dark dorsal shade not strongly contrasted, and 

 oblique lines as in the preceding species. Tubercles brown, in the pale 

 parts of the surface; setae short, pale. Feet pale, equal; spiracles black. 

 Food plant, dead leaves. Dept. Agriculture, No. 2585.

 Body yellowish with fine dark red reticulations crinkled and broken, form 

 ing no bands. Tubercles large, brown, in the pale parts of the surface;

49. Bomolocha caducalis Walker. 



Head 2.3 mm., green, tubercle i black with a little dark blotch below

Frcm the species recorded in Bulletins 35 and 44 of the U. S. 

 National Museum, it appears that only a fraction over 10 per 

 cent, of the described species of North American Noctuidae (ex 

 clusive of the Acronyctae) have had their larvae made known. 

 The present article brings this proportion up to 13 per cent., but 

 this is still too small to make the recognition of species from the 

 larva alone feasible, so that a synoptic table of Noctuid larvae 

 would be of little use at this time. I have, therefore, simply 

 thrown the species here described into synoptic form, to indicate 

 the general lines on which our Noctuidae may be separated when 

 they are better known. This synopsis is also in part supple 

 mentary to the descriptions, as several of the more general char 

 acters here given are not repeated separately under each. 



1. Tubercle iv (joints 7 to 10) behind the center or upper edge of 



spiracle 2 



Tubercle iv (joints 7 to 10) below the center of spiracle or lower. 32 



2. Mottled with brown, the ground usually a lighter shade of brown, 



rarely greenish .... 3
