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



The posterior margin of the metasternal lobe is always 

 sinuate or excavate in the Pygidicraninae. It is invariably 

 truncate in the Pyragrinse, a very Labidurine feature. 



The two curious genera Anatcelia from the Canary Islands 

 and Challia from Korea resemble the Pygidicraninae in their 

 general form and appearance, even to the 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 Pygidicraninae. 



The chief characteristics of the group are as follows: — 



Antennae with over 30 segments ; 3 not much longer than 

 2; 4-7 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 

 of elytra weak, exposing a triangular scutellum of varying 

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

 broad, it scarcely extends over the elytra. 



The piosternumis 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 

 cannulas ; tibiae compressed ; tarsi of various forms.

Tbey were neglected by later authors till Verboeff employed the nar- 

 rowing of the presternum to characterize the Gonolabidae, but the value 

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

 he omitted tu examine all available UonolabiiUe, with the result that his 

 characterization of the family excludes the type of the genus Gonvlabis !
