The balance of the Lepidoptera are classed in a general way as ' micro,' or small, although as a matter of fact many of them are larger than some of the '' macros.'' Yet, as a rule, the fam- ilies contain small, and sometimes very small, forms. At the head of this aggregation is placed the superfamily PyralididcE, which contains species of moderate size, varying greatly in appearance. We have one series, the Pyraustidcs, with slender bodies and rather thinly scaled wings. The pri- maries are banded, the secondaries are moderate in size, never larger than the fore-wings, and the colors are, as a rule, pale, usually a light clay-yellow, while the markings, which are wavy, are yellowish brown or black. The caterpillars in this series are nearly always green, with pale stripes and spots ; sometimes without any markings at all. The head is either black or yellow, hard and shining, and there is a hard shield of the same color as the head on the first thoracic segment. Most of them have the abdominal legs crowned with a complete circlet of spines, and by this character, which is an easy one to see, we can tell with al- most absolute certainty the caterpillar of a micro from that of a macro, in which the circlet of hooks is never complete, if we except the Hepialidcs and Cossidcs, which will not confuse us, on account of their great size and wood-boring habits. The pro- legs are complete,—that is to say, there are four pairs,—and the Fig. 354. The pickle-moth, Margaronia nitidalis, and its larva; the latter shown on a small cucumber which had been eaten into at b. insects have, therefore, no appearance of or relation to the loopers, or GeometiHdcB. Many, perhaps most, of the caterpillars are silk-spinners, and often five more or les
