loi. 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 Agrioninse, indicated as 

 new by Dr. Hagen, but these the writer has not seen.
