what dorsal or ventral, according to the different stages betweeu 

 meager and well fed, or pregnant. Ventral side (Fig. 34) like that 

 of the male except the folio wing particularities. Genital aperture 

 a long trapezium, shut by two doors, each provided with a thin 

 chitinous bar (siguification ? attachment of muscles?), anteriorly 

 limited by a crescent-shaped chitinous bar between the proximal 

 ends of epimera II; posteriorly reaehing the level of the distal ends 

 of coxal plates III. On a line with the anterior end of the anal 

 split 4 small hairs of which the inner are the smaller. Mandibulae, 

 maxillae, legs, like in the male. 



Habitat like that of Gl. cadaverum (Schrank). 



Patria: Frauz-Joseph Archipelago (Fischer), Sweden (De Geer), 

 Netherlands (Oudemans\ Great-Britain (Michael), Germany (Hering, 

 Koch, Thudichem, etc), France (Grognier, Gervais, Gruby, etc), 

 Spain (Fumouze), Italy (Contarini, Moriggia, Targioni, etc), Austria 

 (Kirchner, Karpelles), consequently most probably entire Europe, 

 North-Africa and West-Asia. Further it has been found by . . . . ?

This variety differs from the type in the particularity of having 

 in stead of two front-hairs before the crista, only one bifurcate 

 hair. Of course this hair is a fusion of the two typical front-hairs. 



Since we know that such anomalies are most probably the origin 

 of new species, we must draw our attention to them more than 

 hitherto has been done. I found only one female. *
