Antennae light fuscous with indistinct darker annulations. Labial 

 palpi white, dusted with black. Face, head and thorax bluish white 

 minutely dusted with black atoms, each scale being white with dark 

 lines. Forewings bluish silvery white, densely overlaid with black and 

 brown in ill-defined wavy transverse lines. Each white scale is tipped 

 with black. The apical part of the wing is strongly cupreous brown, 

 especially around the edge. Cilia bluish white, dusted with black.

A Suggestion to Collectors on the Southeastern Coasts of 

 the United States. — Recent study of Eryihrodiplax berenice Drury 

 (also known as Micrathyria or Diplax berenice') and of Hagen's Dy the- 

 litis naeva make it probable that these two Odonates grade into each 

 other as subspecies in the sense of the Code of the American Ornitholo- 

 gists' Union. Berenice has been found on the coast from Massachusetts 

 to North Carolina, naeva in southern Florida, the Bahamas, Cuba, Guate- 

 mala and Panama. Intermediates occur in Texas and Mexico. Of Odo- 

 nata from the coasts of South Carolina, Georgia, northern Florida and 

 the Gulf nothing is known. Anyone familiar with berenice, visiting these 

 last-named localities, would do well to gather a large series of any forms 

 which appeared to resemble berenice and so shed some light on the rela- 

 tionship suggested above. — Philip P. Calvert. 



Editor Entomological News. — I noticed in the Notes and News of 

 the June (1905) News your report of the capture of Pyrgus centaurece 

 at lona, N. J., which is, as you state, "apparently the first record for 

 centaurece south of the Orange Mountains." So much attention is now 

 being given to the making of local lists, and the determination of the 

 geographic range of each species, that the records which I am able, to 

 add to yours will doubtless be of interest. Though not as far south as 

 lona these localities are all farther south than the Orange Mts. The fol- 

 lowing captures were made during May, 1904, on the dates and at the 

 places specified : 3d, one c? centaurece, Millersville, Lancaster Co., Pa.; 

 7th, one ° centaurece, York Furnace, Lancaster, Pa.; 8th, one tf cen- 

 taurece, Peque Creek, four miles from Millersville ; 14th, one $ cen- 

 taurece , Welch Mts., near New Holland, Pa.: 15th, one <3\ one $ cen- 

 taurece, Tucquan, Pa.; 21st, two <$, three 9 centaurece, Tucquan, Pa. —
