Aftisops platycnemis Fieb. 



Head lalher large, with prominent eyes, notocephalic lateral margins slightly 

 diverging from -synthlipsis and again converging toward the vertex ; to the naked eye, 

 the notocephalon appears of equal width throughout. Pronotum overlapping base of 

 head somewhat pointedly, and terminating in a point at the meeting of the heme- 

 lytra. Metanotum completely covered by the hemelytra. Hemelytra pearly, lustrous, 

 varying in color when closed from pure white through a bluish to a blackish tinge, in 

 this respect resembling strongly the shadings of mother-of-pearl. Alar nervurespale ; 

 K\x hyaline. Abdominis dorsum varying from testaceous base and blackish tip to 

 nearly entirely black. X'enter black. Pedes testaceous. Long. 6,7-8. i mm.; lat. 

 2-2.3 mm. 



This species I have taken only in Staten Island with Mr. Davis, 

 where we found it in large numbers in a rock hole in an abandoned 

 trap-rock quarry, on October 25. Its slim, long shape was seen at 

 different depths with its long sweep-like hind legs ready for a swift 

 stroke, floating motionlessly among the algae. We took a large num- 

 ber of specimens on this occasion and a subsequent one. 



This species can be readily distinguished from the local species of 

 the genus Notonecta by its rather long and slender shape, its narrow 

 notocephalon with parallel sides separating the large eyes ; and by 

 the l)eautiful pearly luster of the hemelytra, which vary from a pure 

 white to a blackish tinge, according to the color of the dorsum 

 abdominis. 



NOTES ON THE CICINDELID^E OF THE PINE 

 BARRENS OF NEW JER>EY. 



Bv Charles W. LeN(;, B.S. 



The following notes are prejmred from the collecting experiences 

 of Mr. Edw. D. Harris, Mr. William T. Davis and the writer, who 

 have, separately or together, visited the pine barrens in each month 

 from April to October. The point visited has usually been Lakehurst 

 (formerly called Manchester), situated about seven miles south of 

 Lakewood and in the midst of a typical })ine barren country, where 

 sand, stunted pines and dwarf oaks are repeated with little variation 

 mile after mile ; other excursions have been made to Jamesburg, which 

 is rather on the edge of the pine barren than in its midst, and Brook- 

 ville, which was selected for its proj)in(iuity to the East Plain, the 

 most extremelv barren portion of the jjine barren. On the East Plain,
