NOTES ON THE NOCTUIDiE, WITH DESCRIPTIONS OF CERTAIN NEW 



SPECIES. 



BY H. K. MORRISON, CAMBRIDGE, MASS. 



Charadra decora, nov. sp. 



Expanse 57 mm. Length of body 23 mm. 



Eyes hairy. Antennae simple, black. Abdomen j-ellowish. 

 Anterior wings white, with the usual markings black, wavy, and 

 distinct ; the ordinary lines are marked on the costa by heavy 

 oblique black dashes ; half-line present ; interior line strongly 

 lobed ; the orbicular spot black, figure-eight shaped, very con- 

 spicuous ; median shade present ; the reniform spot large, irregu- 

 lar, open above and below; the exterior and subterminal lines are 

 drawn close together, forming wavy, irregular bands across the 

 wings; at the costa and internal angle the subterminal line forms 

 large black blotches ; a series of short terminal black lines on the 

 nervules ; fringe white, chequered with black. Posterior wings 

 pure white, with a single heavy oblique black dash at the anal 

 angle. Beneath white. 



Hub. California. 



This large and beautiful species is closely allied to our three 

 smaller Eastern ones. 



The white ground color, the peculiarly shaped orbicular spot, 

 and the black mark at the anal angle of the posterior wings will 

 serve to identify it. 



Agrotis badicollis, Grote. 



Ammoconia badicollis, Grote. Bull. Buff. Soc. Nat. Sci., vol. i. p. 136. 

 PL 4, fig. 18 (1873). 



We do not think Mr. Grote's reference of this species to Ammoco- 

 nia, Led., can be followed ; the t} r pe of that genus, the European A. 

 caecimacula, W. V., is a large, heavy-bodied insect, having a broad 

 massive front, pyramidal-toothed antennae, and long hairy lashes 

 to the eyes; the species in question has none of these characters, 

 it agrees with the species of Agrotis having pectinate antennae, 

 and is intimately related to the following new species. 



Agrotis dilucida, nov. sp. 



Expanse 38 mm. Length of body 18 mm. 



% 9. Eyes naked. The antennae of the male strongly bipecti-
