df the trunk or large branches, where their mottled gray color renders 

 them very difficult to detect. 



Tclamona extrema, sp. nov. Plate I, figs. 1, la, and Ib. 



Form of unicolor nearly, smaller and with a still longer hump. 

 Greenish testaceous. Length 9 10mm., $ 9mm.; width 5 mm. 



Pronotal hump very high, almost quadrate, occupying the anterior 

 three-fifths of pronotum, anterior margin rising perpendicularly from 

 face, crest highest just back of the well-rounded anterior angl from 

 which it slopes slightly to the almost perpendicular posterior face. 

 Humeral angles moderate, as long as the eyes. 



Color. Greenish testacious; a spot above each eye and the median 

 carina back to the posterior angle of hump fuscous; posterior face of 

 hump broadly marked with creamy white which narrows to a line on 

 the carina posteriorly in the female, and disappears entirely in the male. 

 The lower margin of the humeral angles is sometimes marked with fus 

 cous. 



Described from two females collected by the author at Anres, Iowa, 

 and a pair collected in Marion County, Kansas, by F. M. McElfresh. 

 The two Ames specimens were beaten from a patch of second growth 

 oak. 



Telamona lugubris, sp. nov. 



Form of redwata nearly, slightly shorter and stouter built and with a 

 lower and longer hump and lacking the markings of that species. Ob 

 scurely greenish brown. Length 9 11mm, $ 9.5mm; width 5.5 mm. 



Dorsal hump of moderate size, arising just back of lateral angles; an 

 terior margin sloping back, forming a right angle with tl?e inclined 

 crest, posterior margin perpendicular or slightly overhanging. Base of 

 hump occupying a little over two-fifths of distance from humeral anglei 

 to apex of pronotum. Humeral angles blunt and obtuse, about two- 

 thirds as long as the eye. 



Color. Pale yellow, the more or less darkened punctures giving the 

 insect a general grayish cast with still darker shad ings on the lateral 

 faces of the hump and sometimes on the apex of pronotum. 



Described from six specimens from Ames, Iowa, collected by tha 

 author, and one from Onaga, Kansas, collected by F. F. Crevecoenr. 



The larva of this species was found quite commonly on the trunks of 

 the scrub oak, feeding on the little sprouts and hiding in the crevices of 

 the bark. The adults were found on the small limb*. 



Telamona decorata, sp. nov. Plate I, figs. 6, and Ca. 



Smaller than lugubri*, with a shorter and more rounding hump. Yel
