smaller size and dotted subterminal line must always distingiiisli it read- 

 ily. The new form has the primaries of a faded orange, all the lines faint, 

 concolorous, so that the wing wants all fascous shadings. The mark- 

 ings are like f err ugineoides, except that they are not laid down in fuscous. 

 The stigmata are concolorous, the reniform upright with contrasting in- 

 ferior stain. Hind wings light yellow, immaculate. Beneath pale yel- 

 low with obsolete exterior line. Expanse, 38 mil. Northern Indiana in 

 June. 



Orthosia inops n. s. 



Bears about the same relation to euroa that ferrugineoides does to 

 ralla. Smaller, brighter colored, the fuscous lines single. Slight

 euroa. Hind wings whitish, with obsolete bands, tinged outwardly 

 with reddish. Beneath with faint double fuscous lines and discal marks. 

 Front and middle tibise and femora brown. Expanse, 26 mil. Kittery 

 Point, Mr. Thaxter. 



Lathosea n. g. 



The head is broad, closely applied to the thorax. Ocelli. Palpi with 

 the third joint rather long and slender. Yestiture shaggy and coarse. 

 Tongue moderate. Eyes naked. Male antennae provided with a series

^ . Gray ; the veins on primaries black ; the fore wings shaded with 

 blackish. Ornamentation simple, consisting only of the two median 

 lines, which are not very distinct. Inner line single, black, forming 

 three very large teeth, one on the cell, one on submedian space, another 

 below vein 1 ; a short tooth on costa. Outer line interrupted, uneven, 

 forming a tooth on vein 1 ; obsolete between the veinlets superiorly : 

 forming black and white dots on the veins j its course is straight after 

 its costal extension, where it is black, continuous, distinctly lined with 

 white outwardly. Fringes white, soiled with blackish outwardly. A 

 terminal blackish shade band cut by white points at the extremity of 

 the black veins, which latter show a fine white edging. Traces of the 

 reniform spot. Hind wings blackish fuscous, subtransparent, the veins 

 darker, the fringes white, incompletely lined; no bands. Beneath 

 nearly concolorous; fore wings darker; the ground is fuscous, with a 

 mixture of white scales; the veins are prominently darker on hind 

 wings, which show a discal cloud. On fore wings the terminal darker 

 edging, interrupted by white' points, is repeated beneath. The hirsute
