1 had inadvertently omitted this species from the list in my "Malayan 

 Blattidae". It has a wide distribution, similar to that of P. javanica. The 

 O. U. M. has specimens from Selangor (H. C. Pratt), Borneo (M. Burr), 

 Sarawak (Shelford), Java, the Philippines, Dutch New Guinea (H. C. Pratt) 

 and New South Wales (J.J, Walker). It has also been recorded from For- 

 mosa, by Karny. To these localities can now be added Sumatra and Ceram. 



Variation in the number of spines of the anterior femora of Pancsthia. 



Stal '), in his definition of P. saiissurii, mentions the varying number 

 of spines on the anterior femora (viz. "femora antica variant inermes, vel 

 spinis duabus vel una armata"), and KARNY ^) confirms StaFs observation and 

 points out that the number of spines can be of no value for the purpose 

 of identification, though SAUSSURE^) had used that character in his keys of 

 classification. KARNY further states that frequently the number of spines 

 may differ between the right and left anterior femora, and also that specimens 

 with three or four spines occur. In the collection from the Buitenzorg Museum, 

 comprising 17 examples of P. sanssnrli, the spines vary from nil to five in 

 number; in 12 specimens the spines are equal on the two femora; in 4 specimens 

 those of the right are more numerous, whilst in no case those of the left pre- 

 ponderate (In the specimen from Sumatra both fore legs are missing). The 

 O. Ü. M. has a series of 19 specime ns, with the spines varying from one to five.
