formed by interspaceal white and following blackish dots. Secondaries smoky, 

 dark along external margin. Head and thorax whitish. Tegulae with black 

 marks. Beneath the legs and thorax are clothed with whitish hair. The 

 wings show double faint shaded darker transverse bands. Expanse 40 m. m. 

 Length of body 15 m. m. 



Habitat. — Rhode Island. 



ARZAMA, Walker. 

 Arzama vnlnifica, Grote. — % 9- — Differs at once from A. densa and A. 

 obliquata by its dusky yellow color. The antennal pectinations are notably 

 shorter in both sexes, especially when compared with our Eastern obliquata. 

 The style of ornamentation is similar. On the entirely obscure yellow ground 

 color of the wings the transverse lines are more distinct than usual, obscure 

 ferruginous. About the large oblique reniform is a dull leaden stain accom- 

 panying the angulated median shade. T. p. line narrowly and evenly lunulat- 

 ed. Terminal space irregularly stained without the s.t. line. Secondaries of a 

 uniform dull red or warm brown tint. Thorax coneolorous with the fore wings. 

 Beneath the yellowish wings show a reddish tinge and are crossed by faint red- 

 dish transverse common lines and have shaded discal dots. Expanse 38 to 

 40 m. m. 



Habitat. — Pennsylvania. 



Less robust than A. obliquata and with the anterior wings more 

 rounded posteriorly.

HELIOTHIS, Ochsen. 



Heliotliis prornptiis, Grote. — % 9- — Belongs to the section of the 

 genus which may retain Hubner's term Melicleptria, and which includes H. 

 villosus. The female has a salient oviduct. Blackish with rusty hairs about 

 the thorax. Over both wings stretches the yellowish-white median space as a 

 wideband margined on the primaries distinctly by the usual median lines; 

 the t. p. outwardly projected opposite the cell. Fringes on the secondaries 

 white, on the primaries dusky. A faint discal spot and faint diffuse stained 

 median shade on primaries. Beneath as above the median spaces are nearly 

 white and the discal spot is black and extends to costa. Expanse 24 m. m. 



Specimens were brought by Lord Walsingham from California and 

 are now in the collection of this Society. 



XANTIIOPTERA, Guenee. 



Xantlioptera coeeinifascia, Grote. — %. — Anterior wings bright 

 straw-yellow. From the middle of the costa an intensely bright rose-red mar- 

 ginal band runs to the base of the wing and is continued over the prothorax. 

 The head and appendages are rose-red. An oblique rather broad and some- 

 what irregularly margined shining rose-red band runs inwardly from costa to 

 internal margin, originating about midway between the extremity of the costal 

 marginal band and the tip of the wing. There is a minute cellular dot on the 

 inner edge of this transverse band. The rose-red fringes appear as an even 

 terminal continued band. Thorax coneolorous with fore wings. Hind wings
