part is a rouuded elevation covered with black-centered pustules, a similar 

 elevation on the outer posterior part of the nietanotum ; nietanotuni slij^htly 

 shorter than mesonotuni ; wing pads greenish, with some traces of veining 

 and some brownish markings, projecting slightly beyond the metanotum ; 

 abdomen short and thick, seven segments, whitish, with light brown mark- 

 ings, the brown areas dotted with white, a dark-centered pustule on each 

 side and somewhat removed from median line in segments 3, 4 and 5, 

 similar pustules on the ^ides of segments 2, 3, 4, 5 and 6, four on the end, 

 four on the 3rd, three on the 4th, two on the 5th, and one on the 6th, a 

 brownish area in the region of these lateral pustules ; segments 3, 4, 5 and 6 

 have a vellow spot on the tergum on each side, about midway between 

 median line and margin, somewhat nearer to the margin; venti-al side of 

 abdomen while ; first and second femora and tibiae banded, brown and white ; 

 posterior femora brown, white at knee ; posterior tibite brown, with lighter 

 stripes, three spines on outer edge (wanting in the adult), one large and six 

 smaller spines at apex, some green in tibite and tarsi ; hind tarsus three- 

 jointed, first joint wide, with four spines at apex, third joint with two hooks. 



The coloration varies, some specimens with more brown than others, and 

 in some the wing pads are greener. 



Abdomen covei-ed with a white, thread-like, cottony secretion, which at 

 the tip of abdomen is formed into a tuft ; a pair of similar tufts on meta- 

 thorax, and another pair on mesothorax. This material is very easily rubbed 

 off in the insect's movements, or in being handled. It gives to the insect a 

 protective resemblance to tufts of hairs on leaves or in the axils of petioles. 



II. Onnoiis scptoitrionalis Spin. 



Four larvae of this species were collected, Attgttst 4, 1902, 

 from a hedge fence coiiipo.sed of variotis kinds of .shrtibs, and 

 bordering one side of a clover field, in the vicinity of Sandusky, 

 Ohio They were on the underside of crumpled leaves of the 

 dogwood ( Cornus asperifolia). Each one was on a separate leaf, 

 situated in a depression between crumpled folds, and was cov- 

 ered, over so as to be almost hidden by the white cottony secretion 

 of wax from its abdomeij^ (Fig. \oa) . Some of this sttbstance 

 was also spread around on the leaf, upon an area having a raditts 

 of one-half inch to one inch from the insect. It is probable that 

 the crumpled tiature of the leaf was the resttlt of its being ptmc- 

 tttred by the insect in feeding. It .seems evident that, tmless dis- 

 ttirbed, they remain upon the same leaf throughout the larv^al 

 period, for leaves were found which had two and sometimes three 

 exuviae .situated on the places where the insects had been feeding, 

 as shown by the presence of the cottony stibstance. 



A dozen or more adttlts were taken from the bttshes in this 

 same locality. One .specimen, still soft and fresh, was found on 

 a leaf near the exuviae of a larva amidst its cottony .surroundings. 

 About two dozen leaves were found having the cottony substance 

 and the exuviae of larvae. These were mostly dogwood leaves, 

 only one being red oak, one hawthorne, and two were prickly ash 

 leaves. 



On the following day, however, examining a different part of 

 the same hedge, extiviaewere found more abundantly on leaves of
