so varied, new species so frequently being described, new characters 

 assuming importance , and the passage from genus to genus so 

 gradual that I have already been obliged to modify the arrange- 

 ment then suggested and further modification will certainly be 

 necessary. In the meantime , I tentatively put forward the fol- 

 lowing scheine : 



Table of subfamilies: 



1. Tarsorum segmentum 2 angustum, sub 3 in lobum angustnm 

 productum (see fig. 5). 



2. Abdomen valde depressum ac deplanatum ; pronotum antic& 

 fortius angustatuni 1. Aiichenominae. 



2. 2. Abdomen convexum, haud valde deplanatum; pronotum antice 

 vix angustatum 2. Chelisochinae. 



1. 1. Tarsum segmentum 2 latum, utrinque in lobum latum dila- 



tatum, cordiforme (see fig. 6). 



2. Corpus apterum , elytris nullis (corpus saepius dilatatum^ 

 sat depressum) 3. Chelichtrinae. 



2. 2. Corpus alatum (alis saepius abbreviatis ; elytris perfecta 



explicatis, vel abbreviatis, vel interdum rudimentär iis). 



3. Meso- et metasterna lata, transversa (corpus latum, depres- 

 sum, saepius fortiter dilatatum) ... 4. Anechurinae. 



3. 3. Meso- et metasterna subquadrata vel paullo latius quam 



longius, haud valde transversa. 



4. Corpus plus minus depressum. 



5. Abdomen medio fortiter dilatatum, apice plus minus angustatum. 



5. Ancistrogastrinae. 

 5. 5. Abdomen medio paullo dilatatum, fere vel omnino parallelum. 



6 . Forficulinae. 

 4. 4. Corpus vix depressum , supra convexum , plus minus dila- 

 tatum, vel lateribus parallelis . . . 7. Opistliocosmiinae. 



Subfamily 1 . Auchenom i n a e. 

 Agreeing with the Chelisochinae in the form of the tarsi, but 

 differing in the remarkably depressed body , the restricted and 

 rare genus Auchenomus deserves Separation into a subfamily. 



Subfamily 2 . Chelisochinae. 

 I have not feit obliged to alter materially the arrangement 

 suggested in the papaer quoted above. 



Subfamily 3 . Ch e l i d u r i n a e. 

 This subfamily remains unchanged except for the inclusion 

 of some remarkable new Central Asian forms described by Semenoif.
