Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; . black markings are so reduced as to be scarcely visible, except on careful inspection. The caterpillar, which is green and nar- rowly striped, feeds on clovers, and, while abundant, is not prac- tically harmful. Among the pets of the lepidopterist are the species of Catocala, a series of large moths with the hind wings black, or yellow and red banded with black. We have a great number of s])ecies, and while the hind wings are so prominently col- ored and marked, the fore-wings are mottled gray, brown, and black. They rest exposed during the day up- on the bark of trees, entirely invisible because so closely resembling their surroundings, the gaudy hind wings being com- pletely covered by the modest fore-wings. While some of the caterpillars feed upon cultivated plants, especially the plum, they are never abundant enough to attract attention. Last in the Noctuids we have the " snout-moths," or deltoids, the latter term applied from the fact that when the insects are at rest the outline bears somewhat a re- semblance to the Greek letter de/la J. The species are recognizable without much trouble by the unusually long palpi, which in many cases point directly forward and form a decided snout. The only species that has occurred in nuiu- bers justifying the term injurious is the Hypena hjinmli, the caterpillar of which —a slender green creature—feeds upon hoi>s. Within my experience it has never been sufficiently troublesome to make insecticides necessary ; but should it ever Catocala ullronia and its larva. Fig. 348.
