356 Mr. A. G. Butler on new Species of 



olivaceous stripe ; costal border sordid plum-colour, densely 

 irrorated in front with white scales, and bounded behind by 

 a black stripe : body white ; the head, collar, margins of 

 the thorax and abdomen slightly yellowish ; a broad belt of 

 dark plum-colour across the prothorax and tegulae ; antennae 

 bright testaceous ; hind margin of eyes red. Wings below 

 with an undulated discal line in place of the sinuous stripe of 

 the upper surface ; body below sordid white, palpi and legs 

 rosy. Expanse of wings 5 inches 10 lines. 



This beautiful species most nearly agrees w T ith the Mexican 

 T. dictynna, but differs in the absence of the conical chocolate 

 patch uniting the ocellus of primaries to the costal border, in 

 the more wavy discal stripe, and the presence of a second 

 stripe towards the base of the primaries. 



Linnaeus evidently confounded T. dictynna with T. luna ; 

 for although, in the 10th edition of his ' Systema,' he quoted 

 Catesby's figure of the North-American insect and Petiver's 

 representation of the same species as illustrations to his brief 

 diagnosis, yet for the fuller description given in the l Museum 

 of Ulrica ' he quoted Clerck's ' Icones ' first of all ; and the 

 figure in the latter certainly represents the Mexican species, 

 inasmuch as the wings are crossed by a well-defined discal 

 stripe. It is probable that both descriptions are taken from 

 the northern type. 



Limacodidse. 



20. Narosa cidta, n. sp. (no. 771). 



Primaries above pale pinky brown ; an irregular transverse 

 subbasal olivaceous line followed by a broad unequal central 

 olivaceous belt, a line of the same colour parallel to and im- 

 mediately beyond the central belt ; a black oblique patch just 

 beyond the end of the cell, and above it one or two little brown 

 lines ; a rather broad olivaceous discal belt, indistinct towards 

 the inner margin; a subconfluent marginal series of black 

 dots : secondaries pale silky brown, with a dusky marginal 

 line : body pale brown. Primaries and pectus below shining 

 greyish brown ; secondaries shining whitish, with indistinct 

 irregular dusky discal line, a discocellular lunule and an 

 interrupted marginal line blackish : venter whitish. Expanse 

 of wings 1 inch 1 line. 



Lasiocampidae. 



Mr. Pryer has sent home a pair of a curious variety of CEona 

 segregate/,, in which the bands are ferruginous instead of 

 blackish.
