NOCTUIDiE. SEGETIA. 153 



wings griseo-fuscous, with two nearly straight dusky strigae, accompanied by 

 two paler ones ; the basal one placed before the middle, the second towards 

 the hinder margin ; between these is placed an obsolete reniform stigma : 

 posterior wings fuscous, with the cilia rufous. The female is of a darker 

 colour, with the strigae less evident. 

 Caterpillar unknown. 



Few examples of this rare species have yet been detected in 

 Britain. In July, 1815, I fortunately captured a female (the only 

 one I have seen) in Coombe-wood; and I have seen others which 

 have been taken near Birch-wood. " Epping," — Mr. H. Doubleday. 



Genus XCVII. — Segetia mihi. 



Palpi slightly ascending, densely clothed with squamose hair; the terminal 

 joint exposed ; triarticulate, the basal joint reniform, stouter than the fol- 

 lowing ; the second as long again as the first, a little attenuated towards the 

 apex ; terminal minute, ovate, obtuse : maxilloB about the length of the an- 

 tennae. Antennae moderate, stout and ciliated in the males, slender and simple 

 in the females : head small : eyes naked : thorax stout, woolly, not crested : 

 wings slightly deflexed, short; anterior obtuse and rounded posteriorly, with 

 distinct stigmata : Z)o<f?/ rather short, the male with a tuft at the apex; the 

 female with the apex acute : legs with the femora very pilose. Larva naked • 

 pupa subterranean. 



Ochsenheimer includes the two species of this genus amongst 

 his My thimnse, forming a section for their reception ; but the ge- 

 neral habit of the insects, and their autumnal flight, seems to indi- 

 cate more than a sectional distinction ; and if we are to consider 

 the outline of any importance in the discrimination of Lepidopterous 

 genera, the dissimilar form of the wings, exclusively of other 

 characters, at once points out their generic pretensions : the dif- 

 ferent proportions of the palpi, naked eyes, abbreviated anterior 

 wings and body, the former with distinct stigmata, may be pointed 

 out as evident characters to separate the genus from Mythimna.

A variable species: head, thorax, and anterior wings castaneous or dusky, 

 sometimes deep fuscous ; the latter with an abbreviated striga at the base, 

 then an irregular one before the stigmata, which are usually pale-yellowish 

 or lutescent, followed towards the hinder margin with a third bent one, 

 formed of minute black spots or connected lunules ; between which and the
