LXVIII. — Notes on the Forficularia. — XXI. Progress in 

 Dermapfera in 1912 and 1913. By MALCOLM BuRR, 

 D.Sc, F.E.S., F.Z.S., F.G.8., F.L.S. 



In response to the sug-gestioii of several friends I offer the 

 followiiig notes on the progess in our study of the taxonomy 

 of the Dermaptera since the appearance of my Fascicule in 

 Wytsman's ' Genera Insectoruin ' in 1911. 



It will be observed that several new genera and a lar^e 

 number of new species have been characterized, and several 

 important alterations of generic position and of synonymy 

 effected. 



I hope at an early date to publish a paper which will very 

 considerably modify the existing system in detail, though not 

 much in general^ embodying the results of the comparative 

 study of the opisthomeres, the wing-venation, the manubrium 

 of the ninth sternite of the male, and of the genital armature 

 of tiie male, and of the gonapophyses of the female, in a con- 

 siderable amount of material, amplifying and enlarging the 

 very valuable work of Zacher on these lines. Tlie results 

 will profoundly modify the generic arrangement of the Psalidje, 

 but will not have any very far-reaching effect upon the other 

 groups. 



Tlie following is the list of woiks referred to in tliis paper 

 which have appeared since the publication of the Fascicule 

 on Dermaptera: —
