The Alypia Caterpillar. 

 The Alypia caterpillar has frequently proved a serious pest in cer-

 off its terminal shoots and thus arresting its extension. It may be 

 readily recognized from the representation given of it in Fig. 8, at a

 The head is yellowish, with about eight black dots on each side. The
