the apical one is nearly as long as the segment itself ; long terminal spnr of 

 liiniltibia nearl}' two-thirds the length of the first tarsal segment. Spurs as a 

 rule with one or more spines. Sexnal armature resembling tliat of geminus. 

 Paronjxhium with long lobes, one on each side. 



(?. Tenth tergite more gradually narrowed than in (/eminiis ; sternite as in 

 that species. Harpe rather deeply concave, intermediate in shape between those of 

 i/rmiiius and cremitoides, with a simple dorso-distal tooth ; no serration (thougli 

 Smith, /.(•., describes the harpe as " dentate and serrate "). Penis-sheath 

 (PI. XXIX. f. T) nearly the same as in fieminxs, the tooth not quite apical : 

 the lobes projecting from the sheath heavily dentate, with the teeth almost 

 arranged in a row. 



?. Vaginal plate closely resembling that o^ geminus, but as mueli wrinkled as 

 m jiistiriae. 



Larva jieculiar, the third thoracic segment being raised anteriorly into a 

 triangnlar protuberance, and the third and fourth bearing a velvety black dorsal 

 patch. — Food : Mentha, Salvia, Monarda. 



Pujja : tongue-case 10 mm. long, straight, slightly separated from the breast, 

 end bulbous. 



Hab. Canada to Georgia, westward to Missouri. (Clemens records it from 

 Texas t).

As said by Schaus, I.e., the present species has nothing to do with lugens of 

 1856, nor is it identical with the species described as separatus by Neumoegen. If 

 one has separates and eremitoides side by side — and docs not compare tiiem too 

 superficially — the distinctness of the insects becomes at once evident. //. eremi- 

 toides is the paler and smaller of the two ; it differs from the other chiefly iu the 

 following jioints : the black abdominal side-marks are smaller, more triangular, 

 the prothoracic tegnlae have no obviously yellow marginal spots, the mesial streak 

 of the mesothoracic tegula is very much narrower, being not essentially lieavier 

 than the black dorsal border of the tegula, which border is distinct ; the basal and 

 medic-costal areas of the forewing are more white, the apical, oblique, interrupted 

 black streak is mnch thinner, the snbliasal white band of tlie hindwing is more 

 grey, and the distal border of the hindwing narrower. The midtibia is as long ( ? ), 

 or nearly as long (J), as the first two tarsal segments together, while in separatus 

 it equals in length the first tarsal segment {<S), or barely surpasses it(?). The 

 foretibia is more densely spinose (PI. LXIV. f. 3) than in separatus (PI. LXIV.
