* Ochsenheimer has divided this genus into four families, the first of 

 which agrees pretty nearly with the second division of Latreille's genus Li- 

 thosia, and the second family contains three species of his genus Callimorpha. 

 Several species of the genera Lilhosia and Callimorpha, l.atr. are arranged 

 by Ochsenheimer under his own genus Eyprepia. Altogether, no small 

 share of confusion prevails with respect to the species of these three genera ; 

 and we hope that some one better qualified for the task than ourselves, and 

 not too fond of creating new genera, will disentangle this perplexed web. 

 We are already indebted to Mr. Curtis for having done something towards 

 it; and the sure grounds which that author goes upon — dissection of the 

 essential parts, and the admirable manner in which those dissections are 

 executed and delineated — not only create unlimited confidence in his re- 

 sults, but leave notliing to wish for, as far as he has gone. To him and to 

 Mr. Stephens, amongst our own entomologists, now actively and so much 

 to their own honour devoted to the science, we must look to have "all 

 these odds made even." Of his genm Lithnsia, Latreillesays (iVo!(r. Diet. 

 (THist. Nat. vol. xviii. p. 130. 1817-), " This genus answers in great measure 

 to the genus Lithosia of Fabricius, and to the Setincs {Setina) of Schrank." 

 And a little further, •' M. Ochsenheimer, in his Lepidoptera of Europe, 

 arranges some of my Lithosice with his EyprepicB, which comprehend many 

 species of Arctia, and my CallimorphcB P "The Lilhosia" Latreilie adds, 

 " are, in general, species of Bomhy.r, having the form of Tinea, either nar- 

 row or elongated, adorned with pleasing colours, sometimes uniform, some- 

 times variegated, and marked with dots, maculae, or bands. Their wings 

 form a sort of mantle. These Lepidoptera remain quiet, during the day, 

 on the trunks of trees, or the stems of plants." 



The species enumerated by Curtis (£n7. Ent. I. 36.) as belonging to this 

 genus are eight : namely, L. muncerda, Hiibn. ; Jlava, Fab. ; aurantia, Haw.; 

 ocZ/reo/a, Hiibn. ; helveola, Hiibn.; complana, Linn.; griseola, Hiibn.; and 

 quadra, Linn. : and he concludes the subject with the following observation : 

 *' L. quadra will form a second division in this genus, since the second joint 

 of the palpus is as long as the first, and curved upward ; Bomh/x pnlclulla 

 and ruhricolUs, Fab., with some others, are included by that author and 

 Latreilie in the genus Lithosia, which has occasioned the latter to state that 

 the palpi are three-jointed, whereas Fabricius has described them as biarti- 

 culatc : after dissecting several specimens of our genus, and examining them 

 most carefully, I can discover only two joints; B. pulchclla and rubricollit 

 having three distinct joints in the palpi, must therefore be constituted into 

 a new genus."
