accolade. The genital skield strongly remembers us of that of 

 Parasitus magnus ; with its anterior margin it follows the exca- 

 vation of the sternal shield. 



Epistoma (Fig. 6) tridentate; the central cusp twice smaller 

 than the lateral ones. 



Hypostoma (Fig. 8). The inner malae feathered outward ; the 

 outer malae of the usual horn-type, sessil. 



Palp (Fig. 8). The first free joint (trochanter) ventrally with 

 two slightly undulated hairs; the second article (femur) with a 

 comblike hair instead of the usual trifurcated one. 



Legs (Fig. 6) slender; leg 1 1200 {*., leg 4 1380 p., coxa 

 1 with a small but distinct spine distally and anteriorly. 



Habitat: decaying leaves. 



Patria: South of France. 



Remark: Probably this is the female of Parasitus Kempersi 

 Oudms. Objections to this supposition are: the different epistoma ; 

 the different situation and shape of the hairs of the posterior 

 dorsal shield; the presence of a mentum.
