BORNEAN DRAGONFLIES. 319 



different in shape ; that of M. exiterfe as shown in the figure 

 given (loc. cit. text-fig. 1 , a) is rather deeply indented, that of 

 M. westwoocli mncli more nearly straight. But the readiest 

 means of discriminating the two species is afibrded by the anal 

 appendages of the male. In the specimens of M. eaterpe I have 

 examined, the upper pair are in every case almost destitute of an 

 external tooth, and are but little shorter than the lower appendix. 



In the case of M. loestivoodi both the specimen before me and 

 that described by de Selys have the external tooth well 

 devoloped, and the lower appendage exceeds the upper pair in 

 length very considerably, projecting beyond them by nearly a 

 third of its total length when seen in profile. 



For the rest I record M. cingtdata Ramb. and M. gerstaeckeri 

 on Martin's authority.]
