JBall Descriptions of New Tree Hoppers* 181 



Color. Deep brownish fuscous, face and lower margin of pronotum 

 mottled with creamy yellow, a reniform yellow mark with a dark center 

 in front of the hump, a large yellow crescent on each side extending from 

 the middle of the humeral angle nearly half way to the apex and enclos 

 ing a few irregular dark spots, an inverted crescentic line extends from 

 a point below the middle of crest. The posterior face of hump is light 

 and this light area connects posteriorly with a transverse light band. 



Described from one male taken at Flagstaff, Arizona, by E. M. Ehr- 

 horn, who is doing good work in the scale insects, and who has sent me 

 many fine Homoptera from lower California, 



Telatnona pulchella, sp. nov, Plate I, figs, 9 and 9a. 



Resembling coryli but much smaller and with a lower, longer hump. 

 Length 5.5-0 mm.; width nearly 4 mm. 



Dorsal hump arising in front of the lateral angles but still back of the 

 face and pronotal line, anterior face perpendicular, crest slightly sloping 

 posteriorly, both angles slightly rounding, posterior margin sloping and 

 rounding into a very marked carina on the apical portion of pronotum. 

 Besides this there are three well marked lateral carinse on the posterior 

 half of the pronotum. Humeral angles long and acute, nearly twice as 

 long as the eye. 



Color. Pale creamy yellow, the lateral angles pale testaceous, the 

 lower margin lined with white which is again margined internally with 

 black. Hump testaceous, omitting the lower half of each margin and 

 an irregular light stripe on the median third. This stripe usually nar 

 rows on the middle and then expands into a crescent below. The testa 

 ceous on the posterior part of hump extends down io the margin of 

 pronotum and there are a few irregular markings towards the apex. 



Described from three specimens collected by the author in southern 

 Colorado. Taken on the scrub oaks of the foot hills. 



Telamona brevis, sp. nov. Plate I, figs. 8 and 8a. 



Form of obsoleta nearly, much smaller and shorter. Smaller and 

 darker than pulchella, dark fuscous brown mottled with pale. Length 

 5 mm.; width nearly 3 mm, 



< Dorsal crest low, rounding from the anterior margin of pronotum to * 

 point more than half way back from the humeral angles, from here it 

 slopes quickly into the curve of the pronotum. Humeral angles large, 

 stout, half longer than eye. 



Color. Fuscous brown, variable, hump darker, omitting the posterior 

 margin and a crescent on each side. An oblique band runs down from 

 the posterior half of hump to the lower margin of pronotum. 



Described from three females collected by the author in southern 

 Colorado. Taken from oak along with the preceding species.
