Fam. B. The two following species are placed in this divi- 

 sion, as connecting the first and third families, Gastr. 

 potatoria being nearly allied in its characters to the species 

 of the family A. and G. lobulina to those of family C. 

 Ochsenheimer gives no separate characters for this divi- 

 sion. 



the terminal obtuse : maxiUa: very small. Antennee short, recurved, 

 strongly bipectinated in both sexes: head small, with an acute, pro- 

 jecting hairy tuft : thorax and abdomen robust, densely pilose, the latter 

 acute in the female : wings dentated, i-eversed during repose : legs 

 moderately stout : the femora and tibice pilose. Larva broacl, rounded 

 above, with fascicles of hair on the sides, each segment with a fleshy 

 lateral appendage, and on the penultimate joint a distinct truncated 

 tubercle: jnipa obtuse, inclosed in an oblong, broadly constructed co. 

 coon and covered with a whitish powder." — Steph, I/lust. Brit. Ent.

" Paljn not very long, porrected, triarticulate, two basal joints of equal 

 length, terminal more slender and obtuse : maxillcB short, a little spiral. 

 AntenrKE nearly straight, not very short, deeply bipectinated in the 

 males to the apex, which is a little bent; slightly bipectinated in the 

 females: head small ; thorax robust, densely pilose : abdomen the same, 

 rather elongate ; more robust in the females : wings, anterior entire, 

 rounded posteriorly ; posterior obsoletely denticulated, reversed du- 

 ring repose : legs rather slender, not very pilose, with minute spurs 

 at the apex of the tibiae. Larva cylindrical, with fascicles of hairs 

 down the sides, and a tubercular eminence on the penultimate joint : 

 pupa short, obtuse, inclosed in an elongate, subfusiform, loosely-con- 

 structed cocoon." — Ste]jh. Jllust. Brit. Entom. Haust. II. p. 50. 



Curtis's generic characters agree, of course, almost exactly with Stephens's, 

 except as regards the middle joint of the palpi, "twice the length of either 

 of the others," which is one of the principal characters assigned by Ste- 

 phens as a reason for separating Bo. l-'ini, Linn., from Ouonestis, the type 

 of which genus, both according to Curtis and Stephens, is lio. potatoria, 

 Linn. Curtis also doubts the existence of maxilla; and mandibles. His 

 description is accompanied, as usual, with a beautiful plate (vol. i. PI. 7.) 

 on which is represented tlie figure of a male perfect insect, taken at Nor- 

 wich, and that of the female caterpillar, copied from Uoesel, together with 

 figures of the dissected antennae and palpi, magnified.
