“Of all the painted populace that live in fields and live ambrosial lives,” there is scarcely a family better known than those which compose the last of all the tribes Hard-shells, the Coccinellidæ. To the young and to the old, to the illiterate and to the scientist, they are equally familiar and equally interesting. Popular sympathy is extended towards them by the elders because they do much good in preventing the excessive multiplication of Aphides; by the juveniles because they are very pretty.

Having spent considerable time during the past season in the collection and study of various larval forms of our twilight and night-fliers, I was peculiarly impressed with the novel colors, markings, and external structural characters presented by those that were taken late in the autumn, at the period when the leaves were donning their autumnal hues. To one who has rendered himself familiar rvith their usual outward characters, a moment's inspection was sufficient to show a marked contrast between those taken early in the season, when the leaves were fresh and green, and those captured later, when the foliage of the trees had sustained a check to their vitality. That these larval changes have a producing cause it shall be my aim to show in the conclusion of the present article.

The meeting with Papilio turnus on the Island of Anticosti, astonished me, as I did not expect to find this butterfly so far north in the Gulf of St. Lawrence. Only two specimens were taken during the season. and old settlers say that it is ahvays rare. Anticosti is evidently its most northerly limit, as it does not occur on the opposite shore of Labrador. It is common at Halifax, N. S., and in many localities along the south side of the St. Lawrence, until we reach the lake and rocky regions on the heighth of land from which the Assomption river flows north of Montreal.

The little insect which I have made the type of this new genus, unites in itself the characters of several genera.

Tongue naked, about as long as the maxillary palpi, which nearly conceal it. The maxillary palpi are about as long as the labial palpi and in the dead insect are laid upon the coxae ; they are rather densely scaled, the scales being somewhat roughened.
