LABIA. 115 



Proreus simulans and P. hulelcingi, and also, as de Bormans 

 suggested from the description, Apterygida erythrocepTiala -, it 

 also recalls Elaunon bipartitus. For this reason it is important 

 to examine the tarsi, as the simple cylindrical second segment 

 will at once remove all idea of its identity with any of the 

 above-named species. 



Perhaps the doubtful Apterygida cingalensis, Dohrn, should be 

 referred here.

Type, Forficula minor, Linn. (Palisarctic and Ethiopian). 



Small insects. Antennae with 10-15 segments ; the first long 

 and pear-shaped, the second very small, the third long, almost as 

 long as the first, fourth nearly or quite as long as the third, 

 the rest gradually lengthening, cylindrical or cylindro-conical. 

 Pi'onotum as broad as the head. Elytra always, wings usually 

 well developed; former with no keel. First tarsal segment 

 hardly longer than the third, the second very small ; the tarsi

not strongly pubescent beneath. Abdomen depressed, some- 

 times rather widened in the middle. Last dorsal segment 

 transverse. Penultimate ventral segment rounded in both sexes. 

 Pygidium prominent or concealed. Forceps various, but generally 

 remote at the base in the (S , elongate or short, nearly straight 

 or strongly curved, unarmed or toothed ; in the $ simple, short, 

 straight. 



Range. Cosmopolitan. 



About fifty species, from all parts of the world, are at present 

 included in this genus ; but it requires subdivision, and some 

 members at least will be removed to other groups. A good many 

 species are unrecognizable owing to insufficient description.
