perdon*). The perfect insects are found for the most part on 

 oak foliage." On Sept. 26 last, Mr. H. S. Jackson, Asst. 

 Mycologist of the Delaware Station, brought me a specimen 

 of a species of Scleroderma which he had taken in an open 

 grove made up rather largely of oak trees. A slight cut which 

 had been made in the Scleroderma revealed the presence within 

 of numerous small, white coleopterous larvae in their cells. I 

 placed the specimen, which measured about one and one-half 

 inches in diameter, in a glass dish, which was covered with a 

 small pane of glass, and set it aside in my laboratory to await 

 developments. One larval cell, which was opened enough to 

 reveal the presence of a larva within, was examined occasion- 

 ally, and on October 5th an adult, nearly of normal color, was 

 found within it. This cell, when examined two or three days 

 previous, had contained a pupa, but the exact length of the 

 pupa stage was not determined. On October i2th, I found a 

 number of specimens in the dish, and by partially breaking 

 open the Scleroderma several more were secured, making 

 about 25 specimens in all. On October iSth, 44 more speci- 

 mens were secured, and a few days later a few others, enough 

 to bring the total to 72, were found. An examination of the 

 body of the Scleroderma showed that it had been pretty thor- 

 oughly worked over by the larvae. 



When a number of the adults were inclosed together in a 

 small vial, a very evident stridulation was noticed at times 

 which reminded one somewhat of that made by Conotrachtht* 

 nenuphar under similar conditions, though weaker, of course. 



It may be of interest to note, further, that a few specimens 

 of C. oculata have been taken in trap-lanterns at this place. 



THE INFALLIBLE ERRS. The March, 1906, number of The Journal of 

 the New York Entomological Society, edited by Dr. Harrison G. Dyar, 

 page 7, lines 23, 24, gives v^scupracens, instead of cii/v-asce>is> as a specific 

 name in Cicindela, and on page 51, line 23, Laca'pede for Lacepede. 

 Very little experience in proof-reading is required to teach the proof- 

 reader how easy it is to overlook typographical errors, and were it not 

 for certain remarks quoted in the NEWS for Dectiuht->\ /QOJ, page _, /*>. 

 we would not dream of calling attention to these slips in our esteeim >! 

 contemporary. It is a certain satisfaction, however, to meet with t \i 

 dence that its Editor is of not altogether different clay from the rest uf 

 the entomological fraternity. ONE OF THK I'IIILADEI.PHIANS.
