Mr. M. Burr — Notes on the Forficularia. 383 



The posterior margin of the metasternal lobe is always 

 sinuate or excavate in the Pygidicranina?. It is invariably 

 truncate in the Pyragrina3, a very Labidurine feature. 



The two curious genera Anatcelia from the Canary Islands 

 and Challia from Korea resemble the Pygidicraninee in tiieir 

 general form and appearance, even to tlie compressed, and 

 carinate femora, but the lobe of the metasternal plate is 

 straight, and the first seven or eight antennal segments do 

 not agree. For the present they may be regarded as aberrant 

 forms which may be most conveniently placed as a sort of 

 appendix to the Pygidicraninse. 



The chief characteristics of the group are as follows: — 



Antennai with over 30 segments ; 3 not much longer than 

 2; -1-7 shoit, not longer than 2, as broad as long, the re- 

 mainder lengthening out to long and cylindrical. 



Elytra quite flat on the dorsal surface, strongly folded, but 

 usually with no keel ; lateral surface hollowed; axillary angle 

 ot elytra weak, exposing a triangular scutellura of varying 

 size. The pronotum is oval or rectangular, but longer than 

 broad, it scarcely extends over the elytra. 



The piosternum is narrowed behind the middle, then dilated 

 on each side at the extreme base. Mesosternum subquadrate, 

 the angles rounded and posterior margin truncate or rounded. 

 Metasternum with lobe transverse, posterior margin sinuate 

 or excavate. 



Femora stout, compressed, and furnished with several 

 carinuke; tibiae compressed ; tarsi of various forms.

They were neglected by later authors till VerhoefF employed the nar- 

 rowing of the presternum to characterize the Gonolabidte, but tlie value 

 of his work in this respect may be estimated when it is understood that 

 he omitted to examine all available CtonolabidtB, -with the result that Ids 

 cliaructerization of the family excludes the type of the genus Gonulubis !
