part of the last century, owing to the cultivation of cotton upon which it 
feeds. It came every year with the zodlogical wave which follows the 
rising thermometer and the extension of summer over the northern-part of 
our Continent. I discovered that the moth hibernates with us (where it 
occurs) as a moth, and that it gradually proceeds northward, breeding as 
it goes, until in the early full months it has passed the area of cotton 
growing, and is found in Maine and Canada in the months of September 
and October. In the North it is very probable that it has found a substi- 
tute food-plant, though I do not know it, upon which the final brood is 
matured. But I found out that it was winter-killed over a large region, or 
sutyiving, the wintering moths failed to make a spring brood. How far 
North this state of affairs is complete is not yet ascertained. 
To resume my remarks on the Anomiingw. Plerwtholix has the male pri- 
mary provided with a blister-like expansion, and the male of the broader- 
winged Ohytoryzea has a smaller one. It. is here that the wings, being en- 
tire, and broadening, tend to resemble the Ophiusinw, and make it likely 
that the large naked-eyed and smoothly-haired Hulepidotis belongs more 
naturally in this subfamily. The body structure is very similar in all the 
genera here discussed and its type, once apprehended, is easy of detection. 
The head is broader and freer than in the Drasteria-like group with which 
I precede Catocala and allies. We have at least two species of Aletia ; the 
second a Texan form which may have also a more southern parentage. In 
form the genus Aletéa is more typical of the group than Anomis with its 
angulated wings. 
1%. Litoprosoping m. This group has the terminal joint of palpi 
elongated, and resembles Plusia, differing by the more robust and un- 
tufted body. The eyes are naked ; tibise unarmed, The wings are long 
and without the broadening outwardly, and the tooth at anal angle which 
characterizes the three next groups. Litoprosopus is a tropical form, and 
Professor Posy describes a species, L. Hatney, from Cuba. Our form is 
found in Florida. 
18. Calpinw m. We have only one genus which is equivalent to the 
FBuropean, and in fact our single species may not be different from Thalic- 
tri. I do not know Hemiceras Cadmia of Guenée, nor whether it really 
belongs to the present group. ‘ 
19. Stirdinw m. This group is characterized by rather weak body-parts, 
the thorax short, having the tegule often deflected at the tips, the collar 
a little relieved, the abdomen untufted, the ovipositor prominent, the 
wings widening outwardly, and often with a projection at anal angle, the 
fore tibises with a claw, the palpi weak and with small third joint, conical 
and more prominent in Basilodes. As a group it oscillates between Calpe 
and Plusia in shape of ‘wing and ornamentation, this being sheeny or me- 
tallic quite often, in armature of tibiee and in appearance (Plagiomimicus, 
Acopa) it presents an oceasional resemblance to the Heliothinw. The palpi 
differ from the Plustinw as also the untufted abdomen and the impromi- 
nent head. I have lately reviewed the genera in ‘*Canadian Entomolo-
