TRIMEROTROPIS SAXATILIS, new species. 



Trimrrotrujiis verrnnilntd Thomas, ^'intli Kept. P^iit. 111., 1880, p. 112. 



Very similar to Ti'iiiicroft'opis ntnculata and possibly not distinct 

 from that species, but differing in the following particulars: 



Scutellum broader; pronotimi with the metazone not more than one 

 and three-quarter times as long as the prozone. with the process rec- 

 tangular. Tegmina, as well as the whole body and limbs, excepting the 

 lower surface of the head and abdomen, extremely variable in color, 

 the groiuid color l)eing white, bluish green, or brown, generally very 

 strongly varied with fuscous, ])ut sometimes nearly plain bv the suffu- 

 sion of the ground color with fuscous. Wings shorter relativel}^ as well 

 as positively, being consideral^ly less than twice as long as broad; fus- 

 cous band broader, being from one-fourth to one-tifth the length of the 

 wing, extending along the posterior border much beyond the middle; 

 apex hyaline, with many or few fuscous spots. Posterior femora with 

 the lower sulcus black, crossed by two white ])ands on the apical half, 

 the median not completely cutting the black. Posterior tibia? varying 

 with the color of the femora; the prevailing color greenish, with a 

 lighter, generally conspicuous, sul)apical annulus. 



Length of body, male, 20 to 22 mm., female, 27 mm.; length of 

 tegmina, male, 22 to 23 mm., female, 26 mm.; length of posterioi" 

 femora, male, 12 mm., female, 13 mm. 



Southern Illinois. Thomas; Union Coiuitv, Illinois (French collec- 

 tion); Arkansas. 



In Arkansas the species is found oidy on rocky ground, and its color 

 varies with the surroundings. Where the exposed rocks are light col- 

 ored or white and covered with lichens the individuals will be white, 

 green, and black in color and so thoroughly protected that it is quite 

 impossible to see them when at rest. 



TRIMEROTROPIS PILOSA. new species. 



Size small, colors plain or dark, but the tegmina conspicuousl}' 

 banded. Head, thorax, and limbs conspicuously hairy. Scutellum 

 very broad, even in the male, but moderately long, being one and a 

 quarter times as long as broad; deeply sulcate, with the median carina 

 distinct. Pronotum with the median carina very moderately cristate 

 on the prozone; metazone nearly twice as long as the prozone, its disk 

 iinely and evenly granulate, and the metazonal process decidedly 

 obtuse angular, the sides straight and the tip rounded. Tegmina with 

 the usual bands distinct, the basal one unusually broad and plainly 

 encroaching upon the light band just l)eyond it, which is unusually nar- 

 row. Wing very broad, l)eing less than one and a half times as long 

 as bi'oad, with the tip not at all attenuate; fuscous ])and rather nar-
