Odenesis, Lasiocampa, Clisiocampa, Curtis. 



Gastropacha, Eutricha, Odonestis, Lasiocampa, 



PcEciLocAMPA, Cnethocampa, Eriogaster, and 



Clisiocampa, Stephens. 



Obs. Ochsenheimer remarks that this genus embraces, in fact, 

 several groups well distinguished by peculiar characters, 



yet 



* In tlie twenty-third Number of his Illustrations of British Entomology, 

 published on the first of this month (February, 1829), Mr. Stephens has in- 

 troduced some further divisions of certain of the preceding genera of Och- 

 senheimer, which we take the earliest opportunity of communicating to our 

 readers. 



1. Genus Fumea, Haworth, adopted to receive the five following species, 



separated from Schrank's Genus Psyche, as given by Ochsenheimer ; 

 viz, nitidella, pulla, viuscella, bombycella? and pectinella, 

 " Fumea, Haw. 

 " Palpi and maxillcB wanting, their place occupied by a tuft of hairs. Arv- 

 tenruB of the male elongate, bipectinated, the pectinations subclavate, 

 ciliated and straight; of the female very short, simple, the two basal 

 joints largest : head pilose anteriorly : thorax slightly hairy, and ge- 

 nerally glossy : abdomen of the male pilose, with a tuft at the apex ; 

 of the female more robust, with a woolly mass at the tip : wings in- 

 cumbent, of the male diaphanous, deeply ciliated, pilose ; of the female 

 wanting : legs rather stout, the posterior tibice very pilose, with elon- 

 gate spurs at the apex. Larva inclosed in a case, in which it changes 

 io ])upa." — Steph. Illusl. Brit. Ent. Haust. II. p. 81. 



2. Genus Nudaeia, Haworth, adopted to receive the three species, mun- 



dana, hemerobia and senex, separated from the Lithosiee of Fabricins, 

 Latreille and Ochsenheimer. — Stephens's second species, hemerobia, 

 Hiibn. is quoted by Ochsenheimer as synonymous with immdana. 

 " NuDAiiiA, Haw. 

 *' faljii minute, curved upwards, squamous, triarticulate, the two basal 

 Joints of equal length, the terminal minute, cylindric -. maxillee longer 



than
