basitriens Walker, Lophodonta ferruginea Packard, Pheosia dimidiata Her- 

 rich-Scliaeffer, Heterocam-pa hiundata Walker, lanassa lignicolor Walker. 



Notodotita basitriens Walker is another fine insect. It is an inch and 

 ten lines in expanse of wings. Its fore-wings are brownish-grey, with a red- 

 dish brown base outlined with brown of a darker shade. It has two trans- 

 verse lines, scalloped inwardly, at about two-thirds of the length of the wing. 

 The bases of the wings of basitriens are suggestive of a small moth, with 

 outspread wings, superincumbent upon the larger one, but in reverse posi- 

 tion. 



Heterocampa pulverea Grote and Robinson, a pretty grey moth, has 

 somewhat of the same appearance (on a more extended sca,le) ; and so has 

 Macrurocampa marthesia Cramer. The prevailing colour of the last named 

 insect is creamy white. The base of the wing is of a warm brown outlined 

 with darker brown. Near the centre of the wing is a distinct brown oval 

 spot. The insect is an inch and eight lines in extent of wings. H. pulverea 

 is an inch and a half. 



A remarkably handsome moth is Lophodonta ferruginea Packard. It is 

 two inches in expanse of wings. Its prevailing tint is a rich cofiee-colour. 

 It has white and brown scalloped lines crossing the fore-wings, and a large 

 white patch on the costa of each of these wings. 



Pheosia dimidiata Herrich-Schaeffer (Fig. 30) is one of the largest of 

 our Notodontians — it is two inches and two lines in expanse of wings. It is 

 our Canadian "Swallow Prominent." The prevailing colour of its wings 

 is white; but in some specimens this is tinged with brown. It has an elon- 

 gated dark brown patch on the lower part of the costa, broken into by a 

 white curved line. Along the inner margin, the fore- wing is dark brown;

and this colouring gradually fades and narrows along the hind margin till 

 it ends at the outer angle. It is interrupted by white linear markings, one 

 of which takes the form of a long oval. At the inner angle of the hind wing 

 is a brown patch. 



A fine moth of neat colouring is Nadata gibbosa Smith and Abbot. It 

 is an inch and ten lines in expanse of wings. Its prevailing tint is ochreous, 

 and it has a band of darker colour across the fore-wing, narrowing towards 

 the inner margin. Within this band, not far from the costa, are twin white 

 spots, small but distinct. Gibbosa bears a remarkable projecting crest on 

 its thorax. 



Nerice bidentata Walker and Symmerista albifrons Smith and Abbot 

 are well known moths. In the former, the brown and grey of the fore-wings 

 in striking contrast — the brown having two tooth-like projections — in the 

 latter the conspicuous white border to the lower half of the costa are features 

 that are easily recognizable.
