28 THE CANADIAN ENTOMOLOGIST. 



March 6, 1909. The stalks showed openings of minute tunnels, greatly 

 resembling pin holes. These holes appeared on one stalk otherwise 

 perforated by Arcecerus fasciculatus. Dr. Hopkins reported that the 

 specimens taken from the stalks constituted two apparently undescribed 

 species as designated. His remark will also apply to the SteJ>ha?ioderes 

 specimens collected by me at Alexandria, La., as previously mentioned. 

 Similar work by these insects was later found by me in an upper joint of 

 a green cornstalk, which, however, was beginning to mature, being found 

 at Alexandria, La., August 2, 1909. 



Batratchetra Rileyi Wlshm. — (Det. A. Busck.) In cornstalks 

 infested by Arcecerus fasciculatus, or where it had worked and left, and 

 decay had begun, numbers of the pink larvae of this moth were living. 

 They occurred particularly in rotting, rain-soaked stalks. Collected at 

 Alexandria, La., September 18, [908; adults matured in breeding cage on 

 October 22 and 29. Larv?e also found frequently associated with or 

 following the work of Arcecerus fasciculatus in green cornstalks, and some- 

 times in ear tips injured by corn-worm, Heliotkis obsoleta Fabr., at same 

 place, August 2, 1909. Mr. J. D. Mitchell submitted pupal cases taken 

 from Arcecerus cavities in cornstalks at Victoria, Tex., March 7, 1909. 



Monorium carbonarium F. Sm.-— (Det. R. A. Cushman.) These ants 

 were found by Mr. J. D. Mitchell in the cells of Arcecerus fasciculatus in 

 old cornstalks at Victoria, Tex., March 7, 1909. 



Pterodela pedicularis L. — (Det. N. Banks). This Psocid bred in dry 

 cornstalks attacked by Arcecerus fasciculatus, collected at Alexandria, 

 La., September 18, 1908. Adults were taken in breeding cage October 

 29, and April 14 following. 



Cluetopsis cettea Wd. — (Det. D. W. Coquillett.) Adult flies emerged 

 August 10 and 23, from green cornstalks cvjllected August 2, 1909, at' 

 Alexandria, La. The larvse appeared to be associated with or following 

 \\\e \\o\k oi Arcecerus fasciculatus \n\o\xtx joints, occurring generally in 

 spots at node or base of leaves. 



Oscijiis carbonaria Lw. — Adult flies emerged August 10 from green 

 stalks as in preceding case, though apparently independent of Arcecerus 

 fasciculatus attack?. 



Oscinis trigavwia Lw.— Det. D. W. Coquillett.) Two adult flies 

 emerged from old cotton boll, Dallas, Tex., March, 1909. 



Gryllus Pennsylvajiicus Burm. — A body of this cricket was found 

 impaled evidently by a loggerhead shrike, otherwise called the southern
