Redescribed from one pair taken on burdock growing on 

 the bank on Niagara River at Buffalo, N. Y., June 28, 1908, 

 and two males taken at Elma, N. Y., August 25, 1912. 



I believe I have rightly identified Mr. Tucker's species as 

 this, although certainty is impossible without reference to the 

 type. I know, however, of no other species that answers so 

 well to his description. The insects of this genus are without 

 a pronotal collum and Mr. Tucker must have referred to the 

 space anterior to the callosities as the collum. 



11. Orthotylus senectus, new species. 



Form of coagulafus but larger ; whitish, irregularly dotted 

 with green above. Length 4mm. to tip of membrane. 



Head a little oblique, with the eyes two-thirds the width 

 of the base of the pronotum. Vertex flat, twice as wide as the 

 eyes; basal carina straight, prominent. Front strongly con- 

 vex, almost overhanging the base of the clypeus. Clypeus very 

 prominent, strongly arcuated before. Eyes prominent, viewed 

 from the side reaching two-thirds the way to the gula. An- 

 tennae rather short, the basal joint nearly as long as the head; 

 third nearly or quite as long as the second. Rostrum almost 

 attaining the apex of the hind coxae, the first joint a little sur- 

 passing the base of the head. Pronotum formed as in coagu- 

 latus, the callosities prominent and the hind margin straight. 

 Basal lobe of the scutellum but moderately exposed. Elytra 

 as in the allied species, the costal margin gently bowing, widest 

 opposite the tip of the clavus. Bristles of the hind tibiae pale, 

 shorter than the thickness of the joint. 



Color whitish tinged with green on the pronotum and elytra 

 and with fulvous on the head and legs ; either side of the ver- 

 tex with a faint fulvous cloud leaving the median line white. 

 Posterior lobe of the pronotum and the elytra irregularly dot- 

 ted with bluish green points. Membrane almost white, the 

 nervures green. Upper surface sparsely clothed with short 

 pale hairs. 



Described from two female examples taken by me at Pueblo 

 and Manitou, Colo., in July, 1900. This species is quite dis- 

 tinct by its whitish color dotted with green above. It doubt- 

 less lives on the whitish vegetation of the semi-arid districts
