Archasia galeata Fabr. 



An apple-greets somewhat triangular tret- hopper with an enormously developed 

 prothorax, occurs on scrub-oaks and other trees from midsummer to early fall. 



This species has the prothorax remarkably developed into an arched 

 shield covering most of the body [pi. 17. tig. 16]. It is triangular in out- 

 line, whether viewed from the front or above, and the membraneous wings 

 extending from under the pronotum, are greenish, brownish or yellowish 

 brown in color. This species is about 3 £ inch in length, and was met with 

 in small numbers on scrub-oaks at Karner in 1901, specimens being taken 

 the latter part of June, during July and toward the latter part of September. 

 This species is occasionally very abundant and infests hickories as well as 

 oak. 



Cyrtolobus fenestratus bitch 

 This is a prettily marked tree hopper measuring only about 3/ l6 inch in 

 length. It is triangular in form when viewed from almost any aspect, and 

 has somewhat the shape of a very small beechnut. The 

 prothoracic shield is irregularly banded with light, 

 brownish yellow, light brown, dark brown and white, 

 and the banded effect is greatly increased by the brown So- 

 wing tips. The eyes vary in color from a yellowish Fig. 152 Cyrtolobii; 



. . 111 T-i • r i • • fenestratus, enlarged 



white to dark brown. 1 hree specimens of this insect (.original) 

 were taken on scrub oak at Karner June 26, 1901. It has been recorded 

 frc >m as far west as Colorado, as ranging north into Canada and as occur- 

 ring in several southeastern states. It is doubtless a widely distributed 

 form. 



Jassus olitorius Say was taken on scrub oak at Karner Aug. 20, 

 1902. 



Pediopsis basilis V. D. was abundant at Karner June 2, 1903, on 

 poplars. 



Idiocerus suturalis Fitch was taken at Karner the latter part of June 

 1903 in considerable numbers on poplar.
