152 HAUSTELLATA. LKPIDOPTERA. 



cylindric, terminal, elongate-ovate^ somewhat acuminated at the apex, about 

 one-third as long as the second : maxilla: as long as the antennae. Antennw 

 rather long, serrated in the males, simple in the females: head and eyes small, 

 the latter naked : thorax stout, woolly : wings shghtly deflexed ; anterior 

 with transverse lines, stigmata obscure or wanting; entire, rounded behind, 

 the apex obtuse : legs rather short, stout : the femora with dense fascicles of 

 hair. Larva naked : pupa subterranean. 



It is not without reluctance that I adopt the present genus, which 

 I have termed Grammesia, in allusion to the transverse lines on 

 their anterior wings, which give the insect the habit of Mythimnse, 

 to which genus they are evidently very closely allied ; but from the 

 observations under the genus Dypterygia, it would be inconsistent 

 to continue the genus Caradrina in the artificial state as left by 

 Ochsenheimer. From Mythimna the Grammesise diifer by having 

 the anterior wings obtuse, and by the woolliness of the thorax ; and 

 from Caradrina by the serrated antennse of the males, the stoutness 

 of their body, and plain, obscure, transversely lineated wings, by 

 which latter mark they may be readily known from Segetia. 



Sp. 1. trilinea. Alis anticis Jlavo- avt griseo-canis, strigis tribus sesquialterd 



fuscescentibus. (Exp. alar. 1 unc. 3 — 5 lin.) 

 No. trilinea. Wien. V. — Ca. trilinea. Steph. Catal. part ii. p. 74. No. 6152. 



Plain flavescent- or hoary-griseous, thickly dusted with minute fuscous atoms ; 

 the abdomen rather paler : anterior wings with three distinct transverse dusky 

 strigfe, the first and third of which occupy the place of the ordinary second 

 and fourth strigse, and the second traverses between the space usually occupied 

 by the stigmata ; there is also an abbreviated one at the base: these strigae 

 vary considerably in their position : the first is slightly undulated, the second 

 a little bent towards the costa, and the third somewhat arcuated ; and in 

 general they are equidistant. Posterior wings fuscous, with pale griseous 

 cilia. 



Var. )S. Steph. Catal. I. c. — Differs in having the strigae approximating towards 

 the inner margin of the wing, and the basal one nearly obsolete. 



Var. y. Steph. Catal. I. c. — With the basal half of the wing to the central striga 

 pale rufo-griseous, the posterior half deep ashy- or rufous-brown ; the central 

 striga very stout. 



Caterpillar ashy-gray, with pale lateral stripes : it feeds on the plantain. 



Found, not very uncommonly, in Coombe and Darenth-woods ; 

 also at Hertford, and near Ripley ; Var. 7 is however less frequent. 



Sp. 2. bilinea. Alis anticis fusco-griseis, strigis duabus rectis, stigmate obsole- 



tissimo interjecti. (Exp. alar. 1 unc. 4 — 5 lin.)

 Of a deeper colour than the foregoing; which it remotely resembles: anterior
