BuiT, Note 011 the Classification of tlie Dermaptera. 327 



Subfamily 4. Ä n e e h u r i n a e. 



The arrangement here is modified. Thnomenus Burr , is re- 

 moved to the Opithocosmiinae. Odontopsalis will probably coincide 

 with Amchura. 



Anechura elongata Borm. will probably require a new genus 

 when better known. Anechura torquata Burr , may require a new 

 genus representing the transition to Allodahlia ; a new genus will 

 also probably be repuired for Pseudochelidura hiolleyi Bor., P. vara 

 •Scudd'. , another for Ps. schmitzn Bor and A. cavalUi Bor. , and 

 another for Ps. edentula Woll. 



A new genus is required for A. feae Borm. , I propose the 

 name Homotages. The elytra haTe no keel , the second tarsal 

 Segment is much longer than in its allies and is scarcely dilated 

 and more than half as long as the third ; the first segment is 

 unusually long , equalling the other two united. The pronotum 

 is of the type occurring in the Chelisochinae , to which subfamily 

 this genus is a transition. The pronotum is decidely longer than 

 broad, and is distinctly widened posteriorly. 



Pseudochelidura analis difiers from the other species in having 

 a keel on the elytra ; this is a very distinctive feature , shared 

 in this family by Allodahlia, but P. analis differs from that genus 

 in the short , quadrate elytra , which are obliquely truncate at 

 the posterior margin. On the strength of these characters , I 

 propose the new generic name Lithinus ; no other known species 

 is included. 



Subfamily 5. Ancistr o g as trinae. 



Poverty of material has hitherto prevented me from working 

 sufficiently at this group. Skendyle Burr must probably be 

 moved here. 



Subfamily 6 . Forficul i n a e. 



The arrangement of 1907 is again modified. I would include 

 here Diaperasticus Burr, now restricted to its type, D. sansiharicus 

 Karsch ; removing F. erythrocephala Oliv., to Elaunon Burr. 



Apterygida Westw. , now only includes its type , albipennis 

 Mag. , as A. arachidis Yers. , is undoubtedly a Labia. Doru Burr 

 is placed here. 



Subfamily 7 . pis thocosmiinae. 



This group is difficult to classify ; I modify the arrangement 

 proposed in 1907 , including here Eudohrnia Burr , Neolobophora 

 Scudd. , Emboros Burr , Cosmiella Verh. , Liparura Burr , Obelura
