H.^BITS. 



In openings in the woods, in places which had been boggy but which were now dried 

 by the heat, I found a few Tettigide>i parfipcnnis, both inuiiature and mature specimens, 

 and one or two Tettix pbbosus (Downer's Grove, ill.. Aug. ig. igol). 



The male of Teltigidea farvifeitms is quite prettilv marked with white over the face 

 and below in front on the pronotum on each side. The palpi are also of the same color and 

 they are kept constantly in motion when the insect is leedmg. Tliese colors are more 

 perceptible if viewed in profile and front. Krom above this ornamentation is obscured, 

 only the somber earthen fuscous of the back, top of head, eves and legs is seen. The 

 female is not ornamented with white, except as to the palpi which are thus marked. 



At Twin Lakes. Wisconsin, the author came to a spring in which the overflowing water 

 passed down as a little brook to the shore of a large lake. In the neighborhood of the 

 spring were butternut and a variety of lu.\uriant forest trees, and in the shade a natural 

 black muck gave nourishment to a rich growth of lichens in the greatest varietv. mosses 

 and other forms of both low and high orders. Even the tree tmnks kept constan'tlv moist 

 were covered with green lichens. In these perpetually boggv surroundings Tettigids were 

 found associated ivith crickets so abundant that the ground was sprinkled over with them. 

 Most numerous were Tettigidea panipeniiis while an occasional Tettix grntiulatiis was 

 seen. Nearer the spring Tettix gibbosui was most common. In all the author caught by 

 hand sixty-seven. The color of Tettigidea famipennis was amazinglv variable, but every 

 insect was perfectly in keeping with the environment. Here one would be on the lichens, 

 another on the swamp grass, and still others on the black muck, and vet all generally speak- 

 ing accorded with the surroundings. The dried specimens have changed since, so that the 

 light clay ochre-yellow on the pronotum of some, and the spots of the same color on the 

 dark ground on the femora have become dull. Whole rows of specimens which when fresh 

 presented the prettiest variations now present a dark, uninteresting hue.— .\ug. 27, 1898.

 than twice the width of one of the eyes in the female, in the 

 male little wider than one of them, the fronto-lateral carina 

 slightly oblique, little more rounded in the male, lateral mar- 

 gins of crown strongly sinuate, widened posteriorly, the supra 

 ophthalmic lobules more or less conspicuous, median carina
