191-i.] NATURAL SCIENCES OF PHILADELPHIA. 521 



Local Distribution. — Confined to the Coastal Plain, where it 

 usually appears to be of infrequent occurrence, though in some 

 seasons it may be fairly common. Does not seem to occur on the 

 beaches. 



Ecological Distribution. — Seems, so far as my experience with 

 it goes, to be more campestral in its hal^itat preferences than the 

 other species of the genus. Frequents low scrub and grassy thickets 

 in dry locations. 



Locality Records. — 



Middle District. — Lucaston (N. J. St. Mus. Rep.) ; Jericho, in 

 sandy barrens (Fox). 



Pine Barrens. — Atsion (Hebard); Parkdale (Rehn and Hebard). 



Coastal District. — Ocean View (Fox). 



Cape May Interior. — Sea Isle Junction (Fox); S. Seaville (Fox); 

 Clermont (Fox). 



MICROCENTRUM Scudd. 

 M. rhombifolium Sauss. (= laurifoUum Linn.). 

 M. retinerve Burm. 



PIEROPHYLLA Kirby (= Cyrtophyllus). 

 C. perspioillatus Linn. 



The three preceding species are the more strictly arboreal forms, 



which were not studied in connection with the present investigation. 



The few specimens which I took add practically nothing to the data 



already published elsewhere. 



CONOCEPHALUS Thunberg of authors. 



(= Conocephaloides Perkins.) 

 C. robustus Scudder. 



General Range. — Coastal New England south near the coast to 

 North Carolina; local in the interior, especially about the region 

 of the Great Lakes. 



Local Distribution. — Of common occurrence throughout the 

 Coastal Plain, especially in the Middle and Coastal Districts; rather 

 local apparently in the Pine Barrens. Frequent on the beaches. 



Ecological Distribution. — Typical of tall, grassy thickets in 

 both moist and dry situations. Largely limited to campestral 

 stations. Not frequent in salt marshes.
