Vol. 1] Van Duzec. — Lake Tahoe Hemiptera 245 



on July 5. Typical examples of Bolteria picta Uhler received 

 from Mr. Heidemann show but few black hairs and they seem to 

 be entirely wanting from specimens taken by me on the plains 

 about Denver, Colorado. 



HOMOPTERA 



Okanagana rimosa Say. Common at all levels from Fallen 

 Leaf Lake up to 8500 feet on Angora Ridge, the first individuals 

 appearing on July 3. This species has the habit of resting in 

 trees fifteen or more feet above the ground, and being wary are 

 very difficult to capture. 



Okanagana ornaia Van D. On July 11 I took from low oak 

 bushes growing on the top of the lateral moraine east of Fallen 

 Leaf Lake three male examples of a form agreeing entirely with 

 ornata except that the orange colors are replaced with pale 

 testaceous. Possibly the local conditions might account for this 

 difference in color or these specimens may not have been fully 

 colored. 



Aphropliora permutata Uhler. Common at lower levels and 

 first reaching maturity about July 15. 



Stictocephala pacifica Van D. Not uncommon about Fallen 

 Leaf Lake during July. 



Telamona harbata Van D. On July 30 I took numbers of 

 what may prove to be this species from a willow having pale 

 green foliage, growing on the southern slope of ]\Iount Tallac. 

 These have the crest more erect and elevated than the types from 

 New York State. 



Telamona ohsoleta Ball. One example of this form was beaten 

 from a willow near Glen Alpine Springs, July 22. 



Orgerius rhyparus Stal. Two fully grown examples were 

 taken near the lower end of Fallen Leaf Lake July 17. 



Elidiptera woodworthi, new species 



Closely allied to septentrionalis ; broader, more mottled with white; 

 front whitish with its base and the clypeus fulvo-testaceous. Length 

 7 mm. 



Vertex a little shorter than in septentrionalis, scarcely as long as 

 broad, the impressed median line almost obsolete in the female. Front 

 a little narrower than in the allied species, sides almost rectilinear, at 

 apex curving inward to base of clypeus. Pronotum as in septentrionalis, 

 narrowly produced to about the middle of the eyes and truncate at apex.
