HanitscH: Blattidae from the Buitenzorg Museum, 



215 



In 9 specimens the spines are equal on the two sides; in 7 cases those 

 of the right preponderate, and in 3 cases those of the left. 1 obtained similar 

 results by examining the series of 37 specimens of P. javanica in the 

 O. U. M. The spines varied from nil to five; in 25 cases they were equal 

 on the two sides ; in Q cases those of the right preponderated, and in only 

 three cases those of the left. An examination of other species of Panesthia 

 brought the same result: the spines are never constant in number; in most 

 cases they are equal on the two femora; if they are unequal, then those 

 of the right more often preponderate than those of the left. The following 

 tables give particulars, the first column indicating the locality, the second 

 the Collector's name, and the third and fourth the number of spines on the 

 left and right anterior femora respectively.
