101. Diplax corrupta Hagen. One male on the sea-shore near 
New Brighton, Staten Island, June 27, 1896, by Mr. Wm. T. Davis, 
and submitted to the writer for examination. Mr. Davis recorded that 
the frons, base of the wings and abdomen were scarlet in life. Compare 
also Mr. Van Duzee’s paper. This is a common western species which 
perhaps is extending its distribution eastward. See also Trans. Am. 
Ent. Soc., xx, p. 264. 
Dr. Lintner also mentions four species of Agrioninae, indicated as 
new by Dr. Hagen, but these the writer has not seen.
