sciuiiri', aliuost as long as (he sculuiii in tiic iiiiddlc ; uu'tasciiluiii short. 1h<^ 

 two lialvcs l)cini( uniteil by a very short istliuius. The sciitelhiiu is sliort ami 

 crcscciit-shajx'il. 



]>l(.i,,ni,i — The llauks arc very oblique. Tlie coxa' and trochantines col- 

 leelively are rallier short, tliick, and soniewliat swollen, though not so much 

 so as in Toiirix. 



i*hulini\d(c {Eiitrapela tvansversata, pi. 7, fig. 21, 21rt). — We now come 

 to moths in wliieh the thorax becomes more spherical and concentrated than 

 berore. This is due to Andouin's law of enlargement of one part of a seg- 

 nu'nt at the exjiense of an adjoining jiart. The ditlerences may l)e best 

 brought out by comparing the thorax of an Eiitraiula with a ILulriia The 

 entire thorax is longer than in Ucidfna; the Hanks are more ol)liqi!e. 



Tergum. — Tin; mcsoscntuni in the median line is ai)out as long as the 

 (uitire piece is wide. The sciitellum is considerably shorter than wide, and 

 does not (hirer from that of Hadr/it/. The two pieces of the meta.scutnm arc 

 widely separated by a distance nearly equaling the width of the scutellum. 

 The latter is very short, transversely linea'r-obloiig rather ti)an crescent- 

 shaped. 



I'leurum. — The epimera and episterna are rather narrower and scarcely 

 as long as in Iladvna, while the co.XcC and trochantines are longer and much 

 narrower. The proportions are the same in A)ihoptcnjx pomcfaria 9, PI 7, 

 Fig. -. 



Nocluidce {Iladena desfn/c/or, pi. 7. fig. 15, 15a). — The thorax is, shorter, 

 Ujore s|)herical, and the Hank less oblique than in the P/taicoiidw. 



^i'ergum — Meso.scutum shorter on the mediau line than broad. '^1 he 

 two halves of the ineta.scutuin arc i)ot so widely separated as in the Plialcc- 

 nidce, the distance between them being equal to about half the width of the 

 scutellum. The scutellum is linear crescent-shaped. 



I'leurum — The characters have already been brought out in the descrip- 

 tion of the rh(da'ii'id(e. 



]i()j)ihijcidre {Telca Pohjpliemus, pi. 7, fig. IG, IGt/). — The thorax in Tclca 

 is not so spherical as in Jhidoiti, w liih^ the llauks ai'c much less oblitpie. 



'^rergum. — The mesoscutiim is shorter than in the FluilixnUkc, \\hile the 

 scutellum is c(pfilaterally triangular, being less produced behind than usual, 

 'i'lie two halves of the metascutum are widely separated, much as m IladiiKi, 

 and the scutellum i.s much the same.
