BYXHOSCOIPIDAE 



Bythoscopus cognatus VanD. A few taken on Cobble Hill. 



Bythoscopus minor Fitch. One example from the low woods 

 along the Ausable river. 



Bythoscopus pruni Prov. Abundant everywhere in the Adiron- 

 dacics on birch and alder. 



Pediopsis viridis Fitch. Common on willows. 



Pediopsis trimaculata Fitch. Taken at Axton by Professor Mac- 

 Gillivray. This is the trimaculata of my catalogue not 

 my i n s i g n i s which Osborn and Ball now place as Fitch's 

 trimaculata. 



Pediopsis canadensis VanD. Two examples were beaten from 

 alder bushes on the Lake Placid Club grounds. 



Pediopsis basalis VanD. One dark specimen taken on Cobble 



Hill. 



Idiocerus pallidas Fitch. Common. 



Idiocerus suturalis Fitch. Abundant everywhere on poplars. 



Idiocerus suturalis var. lunaris Ball. This variety or race 

 occurred here as elsewhere with the typical suturalis. What- 

 ever its relationship may be with that species it certainly should 

 have a name by which it may be distinguished therefrom. 



Idiocerus alternatus Fitch. Not common. 



Idiocerus lachrymalis Fitch. Taken on the summit of Mt 

 Whiteface and at other places on Populus grandiden- 

 t a t a . The males of this species are much smaller than the 

 females and somewhat resemble alternatus. 



Idiocerus provancheri VanD. One example beaten from a thorn 

 bush. 



Agallia novella Say. Occasional. . 



Agallia 4-punctata Prov. Taken on the summit of Mt Whiteface 

 and elsewhere.

22, 1902.

Deltocephalus configuratus Uhler. Not uncommon. One darkly 

 colored female was taken on the summit of Mt Whiteface. 



Deltocephalus minki Fieber. Taken Sep. 22, 1902, near Lake 

 Placid. On Aug. 25 of this year [1904] I swept numbers of them 

 from grass on the hillsides at Phoenicia in the Catskills. 



Deltocephalus sylvestris O. & B. Taken in open woods near 

 the Ausable river and on Cobble Hill. 



Deltocephalus melscheimeri Fh. Several taken on Cobble Hill 

 and elsewhere. This is the smallest species of Deltocephalus 



known to me.

 the pale yellowish forms to those with black elytra.
