50 MAINE AGRICULTURAL EXPERIMENT STATION. 1917. 



Genus CLEORA Curtis. 



Body of usual type ; face-parts not much elevated ; antennae 

 reaching the caudal margin of the wings, the distal end of each 

 curved slightly mesad ; a small portion of the labial palpi ex- 

 posed caudad of the labrum; maxillae reaching almost to the 

 caudal margin of the wings, the proximo-lateral angles not 

 extending quite to the eye-pieces ; prothoracic legs three-fourths 

 the length of the wings, their femora exposed; mesothoracic 

 legs equal in length to the maxillae; mesal length of prothorax 

 two-fifths that of the mesothorax, mesothoracic spiracle with an 

 ovate tubercle adjacent to its caudal margin, the surface covered 

 with fine setae; mesal length of metathorax one-fourth that of 

 the mesothorax; first eight abdominal segments coarsely punc- 

 tate; the spiracular furrow present cephalad of each spiracle on 

 the fifth abdominal segment, the surface of the furrow very 

 rugose; dorsal furrow never present between segments nine 

 and ten; abdominal spiracles almost circular in outline; cre- 

 master triangular at base, the distal half spine-like, and slightly 

 bifurcate at tip. 



This genus includes a number of species but only two are 

 commonly found in Eastern North America. One of these 

 Cleora pampinaria is described here.

 Fig. 2, F and I. 



Color chestnut brown, usually without markings, some- 

 times with a few small dark spots on the appendages ; face-parts 

 and appendages almost smooth and appearing polished; pro- 

 thoracic leg slightly elevated near the large exposed part of the 

 femur ; thorax smooth, or with very fine transverse impressions ; 

 abdomen densely punctate with medium punctures on the first 

 eight segments; spiracles almost circular, the openings ellipti- 

 cal, that of the sixth slightly ventrad of the others; spiracular 

 furrow (Fig. 2, I) with the surface deeply rugose, the outer 

 edge heavily chitinized, almost black and apparently serrate; 

 surface slightly concave between the furrow and spiracle, crossed 

 by faint elevated lines; cremaster about 1 mm. long, the dorsal 

 surface convex and rugose, the distal end spine-like and bifur- 

 cate.
