Zoology at Cambridge, and they agree perfectly with Mr. Grote's 

 description ; but I am also in doubt whether Mr. Morrison's 

 description of the female really applied to this species, of which 

 I have females only. But as there is no other to which the 

 description applies, even approximately, I have adopted Mr. 

 Grote's identification. 



Of the names* now in the catalogue, oblonga, subcarnea, and 

 permagna apply to one species only, reducing the number of 

 good species to three, and to these must be added a new form 

 from the Pacific coast bred by Mr. A. Koebele some years ago. 



Of three of these species I have material sufficient to study the 

 male genitalia ; of Iceta I have seen only cne male, and that was 

 not available for dissection. The matter is not so important in 

 this genus as it would be in some others, because the characters 

 seem to have no modification corresponding to the extraordinary 

 female structures. On the contrary, they are extremely simple ; 

 the harpes are long, moderate in width, subequal to near the tip, 

 but somewhat irregular ; the tip rounded and varying a little in 

 form. Oblonga seems to have no corneous clasper of any kind, 

 and on this point I examined the subcarnea as well as the pcr- 

 magna forms and a series from California, lest I might be misled 

 by superficial resemblance. Subflava and alameda have each a 

 curved corneous clasper inserted at about the outer third of the 

 harpes and projecting forward. The uncus is unusually thickened 

 in all the species, but there seems to be nothing different in type 

 from the usual Noctuid form. 



Oblonga Grt., is the largest of the species, reddish gray in color, 

 with minute black powderings, which tend to form in the male, 

 a blackish shade along the median vein. The t. p. line may be 

 represented by a simple or a double row of dots, or may be trace 

 able as a denticulate line, the dots being the remains of the teeth. 

 The ordinary spots are usually traceable as more reddish blotches 

 in which the powderings are not present. Mr. Grote's original 

 description was of an average male and fits that sex nicely ; in 

 the female all the maculation tends to become lost and the extreme 

 in that direction is permagna Grt., represented in the series be 

 fore me by Californian specimens which agree closely with the 

 type from Florida. The normal form is described by Dr. Kelli- 

 cott, and in this the t. p. line is punctiform, the orbicular is marked 

 by one and the reniform may be marked by two dark dots. 



Subjlava is distinctly yellow in tinge, and has the veins more 

 or less marked with smoky or blackish ; the median vein is espe 

 cially prominent, and at the end a diffuse spot tends to darken 

 the vague reniform. The t. p. line is a series of venular dots and 

 the terminal space is dusky in most examples. Females usuallv 

 vary little except in size and in the general tinge of the ground 

 color. The males are generally so different that, without a series,
