ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Major James Carroll, Surgeon, U. S. A., died September 16th, in 

 Washington, D. C. Major Carroll was a member or the commission 

 that proved that mosquitoes transmitted the cause of yellow fever to 

 human beings. All honor to his memory. 



Cambridge Entomological Club. — The Club held an exhibition of 

 Insects on Wednesday, Thursday, Friday and Saturday, November 20, 

 21, 22, 23, at the rooms of the Appalachian Mountain Club, in the Tre- 

 mont Building, 73 Tremont St., Boston. 



The office of State Entomologist has been separated from the chair of 

 Zoology and Entomology of Clemson College and located at Columbia, 

 S. C. On September 11, 1907, Prof. Chas. E. Chambliss resigned his 

 position of Assistant Professor of Zoology and Entomology to accept the 

 appointment of State Entomologist. 



Captures of Diptera. — The following of my captures of flies during 

 1907 are of interest ; Dizotiias tristis, Washington, D. C, June 21 ; Vol 

 ucella obesa, Glencarlyn, Va., June 28; Pterallastes thoracica, Glencar- 

 lyn, Va., June 14, at Ceanothus ; Gymnochaeta alcedo, Falls Church, Va., 

 July 20; Pterocalla strigula, Washington, D. C, September 5; and, 

 Pseudotephritis cribellum, Falls Church, Va., September 30. I also took 

 a few more specimens of Cordiligaster minuscula and Cyrtometopa fer- 

 ruginea. The former is fairly common at some places along the Potomac 

 river, five or ten miles above Washington. — Nathan Banks. 



Occurrence of Dilar Americana McLach. — This rare Neuropteron 

 of the family Hemerobiidae was described from one female taken by 

 Sanborn in Kentucky. The type and only recorded specimen is now in 

 the Museum of Comparative Zoology. On July 20, last summer, while 

 collecting in an open woods near Falls Church, Va., I saw three fluffy- 

 winged little insects on the bark of a large tree. I placed a vial over 

 two, the third flying away. Once dead, I recognized Dilar arnericana ; a 

 male and a female. The male resembles his mate, but is rather smaller and 

 darker, and of course, with the pectinate antennae characteristic of the 

 males of this genus. — N. Banks.
