Papaipema nitelia Gn. ( Syn. Gortyna. ) The Potato Stalk Borer 

 Larva boring in twigs of black locust, peach and several herbaceous 

 plants.

Acronycta americana Harr. (Syn. Apatela). The American Dag- 

 ger Moth. The larva of this moth feeds upon the black locust and 

 several forest trees, of which the maple is its favorite.

Halisidota tesselata A. & S. The Tiger Moth. Larva feeds upon 

 leaves of several forest trees, among which is the black locust.

Sabine stimulae Clem. (Syn. Emperetia). The Saddle Back Cat- 

 EPiLLAR. The larva of this moth is easily recognized by a large green 

 patch on its back, on which is a purplish-brown oval spot, from which it 

 •derives its name. It is a general feeder, eating the leaves of a large 

 number of trees and vines, but seems to prefer the Virginia Creeper.

Family Liparidae. 



Hemerccampa leucostigma S. & A. (S)'n. Notolopus). The White 

 Marked Tussock Moth. The moths of this species emerge in the fall. 

 The female is wingless and lays her eggs upon the cocoon from which 

 she just issued, covering them with a white frothy mass. The cocoons 

 are placed against a tree trunk or on a twig, and in the latter case are 

 usually partly enclosed by a leaf. The eggs hatch in the spring and the 

 larvae feed singly. They are very prettily marked, and are the most beau- 

 tiful of our caterpillars. The body is clothed with white hairs ; the head 

 and two glands near middle of back are bright vermillion red. A broad, 

 velvety black strip extends along the back, with yellow ■ stripe on either 

 side ; just below the spiracles is a second yellow stripe. A dense brush-like 

 tuft of cream colored hairs is borne on each of the first four abdominal 

 segments. The prothorax bears two plume-like pencils of black hairs, 

 and a similar one projects backward from the eighth abdominal segment. 



Both the larvae and pupae are quite extensively parasitized, but direct 

 measures are necessary to control this insect. The larvae, being voracious 

 foliage feeders, may be poisoned with an arsenical spray. The cocoons 

 which remain on the trees over winter may be gathered, but should not 

 l)e destroyed, because of the parasites they are likely to contain. They 

 should be placed in a box away from vegetation, so that any newly 

 liatched larvae will starve, and yet allow the parasites to escape. On
