Ostoinodcs Reitt. erected by Reitter for the species Grynocharis 

 pilosula Cr. and mainly founded on the supposed toothed claws, which 

 however, was an error. Leveille calling attention to the mistake re- 

 jected the genus but later restored it again. 



Lophocateres Oliff. with one species L. americanus, described by 

 Motschulsky from New Orleans, is to be added. 



Thymahis Duft. remains unchanged. 



Lycoptiis Casey. A genus of doubtful position which was first 

 placed by its describer in the Colydiidse and later in the Trogositidse. 

 It is unknown to me. — Chas. Schaeffer. 



A Long Island Ants' Nest Eighteen Feet in Diameter. — On 



the slope leading down to the southerly shore of Deep Pond near 

 Wading River, the writer found on July 26, 1914, a nest of Formica 

 fusca rar. subscvicca Say eighteen feet in diameter. In the other 

 direction it was somewhat broader, about twenty feet. This is the 

 largest nest of the species I have ever found. Many of the ants came 

 out when I walked across the nest in measuring it, and attacked me. 

 Sometimes these ants, when the nest is small, do not show such cour- 

 age. The nest of this species is usually not high and mound-like, as 

 is that of Formica exsectoidcs Forel, which also occurs at Deep Pond, 

 but is more spread out over the ground and is generally about two or 

 three inches high. The large nest here referred to is in open woods 

 of pines and oaks, in a not very sheltered position, and does not receive 

 as much sun as it would have had on the opposite side of the pond. 

 ]\lr. Charles Schaeffer later viewed the nest and agrees with me that 

 it appears to be the work of but one colony. — Wm. T. Davis. 



Slides of Wings of Macrolepidoptera. — I have found the 

 following method convenient for preparing slides of the wings of 

 Macrolepidoptera, and fairly good for Pyralids and Pterophorids. 

 (i) Remove wings of right side carefully. The frenulum is less apt 

 to be broken if the wings are removed together and separated later. 

 (2) Wet with alcohol. (3) Transfer to Labarra.que or Javelle solu- 

 tion. I find both are equally good, but either must be fresh enough 

 to work quickly or the stain will not take smoothly. (4) Wash thor- 

 oughly with water or alcohol or both. (5) Leave 12 to 36 hours in a 

 stain composed of 5 per cent, by weight of sodium eosin (for instance
