910 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



INSECTS INJURIOUS TO THE COMMON JUNIPER. 



Jiiniperus communis. 



1. The low-bush juniper inch-worm. 



Eupithecia miserulata Grote 



Order Lepidoptera ; family Phal^nid^. 



Feeding on the common low spreading juniper bush, a small pea-green span-worm, 

 with a narrow thread-like subdorsal and a wider lateral white line, changing early 

 in June to a chrysalis contained in a thin white cocoon, the small moth appearing at 

 the end of the month and through the summer. 



This small delicate common moth was reared by Mr. Cassiuo at Salem, 

 Mass., and like its European congeners lives on the bush juniper (not 

 on Taxus haccata, as stated in ray monograph of geometrid moths). 

 The larva was found late in May, and June 4 began to spin, the pupa 

 being inclosed in a slight white cocoon. It ranges from Maine to Texas. 



Larva. — Of the characteristic form, being rather thick in the middle, the body seen 

 dorsally decreasing in thickness from the tail to the head. Supra-anal plate large, 

 triangular, not acutely pointed, deep red, white on the edges. Head small, not so 

 wide as the prothoracic ring, pea-green, color of the leaves on which it feeds, dorsal 

 line dark-green ; subdorsal white, and a wider lateral white line. Segments trans- 

 versely wrinkled. Body provided with short, black, scattered hairs. Length, 0.50 

 inch. 



Pupa. — Four abdominal segments project bejond the ends of the wings, the thorax 

 and under side of the wings and limbs with a greenish tinge ; the rest of the body 

 pale horn-brown, as usual. Head full, convex between the eyes. End of abdomen 

 with a long rounded spine, with three pairs of long hairs curved outwards at the 

 end. Length, 0.2S inch. 



Moth. — This is our most common pug-moth, and may be distinguished by the pointed 

 fore wings, with the numerous transverse lines angulated sharply outward, the extra- 

 discal line formipg a sharp angle opposite the discal dot, and notched inward on the 

 subcostal vein ; by the distinct submargiual wavy white line ending in a large white 

 twin-spot at the inner angle ; by the fine dark lines on the hind wings, and by the 

 heavy black costal spots and marginal lines on the under side. The fore wings ex- 

 pand 0.85 inch. 



2. The juniper web-worm. 



Dapailia rutilana Hiibner. 



Order Lepidoptera ; family Tortricid^. 



The following account is taken from Professor Riley's report to the 

 Department of Agriculture for 1878, with the accompanying illus- 

 tration : 



"This leaf-roller has been found to seriously injure the imported 

 Irish and Swedish junipers {Juniperus communis var.) in nurseries on 

 Long Island, having first become known in this country in ISTTj it has
