tion is readily effected. The thread-like neuter flowers appear 

 to keep the beetles among the pistillate flowers after the dis- 

 agreeable odour ceases, for they seem to like going in and 



out under them during the day, in the second stage of the 

 spathe. 



The trap-mechanism of the Ghet-Kachu resembles that of 

 the Cuckoo-pint {Arum maculatum) in the entrance and exit, 

 being above through the same opening at the constriction of the 

 spathe, but it differs from it in the deliberate opening and 

 closing of the passage leading down into the tube of the spathe, 

 and in the staminate flowers being situated on the exposed 

 upper part of the spadix and not within the tube. 



The floral-mechanism of the Ghet-Kachu differs much 

 from that of the common Kachu (Golocasia antiquorum), in 

 which the entrance for the flies is formed by the margins of 

 the spathe opening slightly only in front below the constric- 

 tion, and the exit by the spathe opening only partly above. 

 However it resembles that of C. antiquorum by having no 

 neuters at the constriction and bv the closing " of the con- 

 stricted part of the spathe after the first stage, but again 



differs from it by the constriction reopening in the second 

 stage. 



The floral-mechanism of the Ghet-Kachu does not seem 

 to be so perfect as that of 0. antiquorum, the common Kachu, 

 but it appears to be an advance on that of the Cuckoo-pint.
