276 SPECIFIC DESCRIPTIONS OF 



perceiving the difference between the present species 

 and the one known to himself as N. ccsmentaria, Latr., 

 concludes it to be identical with N. meridionalis, Sim. 

 Examples, however, of this latter, from M. Simon's 

 cabinet, show that they are very distinct. 



On N. meridionalis, Sim., see p. 289 ; and on 

 N. ccementaria, Sim., p. 280, M. Simon has, I under- 

 stand, subsequently admitted the error of his conclu- 

 sion, published I.e. SNjjra. 



Habitat. San Eemo, Mentone, Cannes, Hyeres, and 

 Marseilles. 



Nemesia incerta, sp. n., Plate XIX., fig. D, p. 229. 



Adult male, length slightly above 4J lines. 



CephalothoracV oval, truncate at each end ; mode- 

 rately convex above, the profile line forming a pretty 

 even, sloping, curved line, but fiattish in the middle 

 near the thoracic fovea, which is of a strongly curved 

 form ; the other normal indentations are not strong, 

 though fairly defined ; the colour of the cephalo- 

 thorax is yellow-brown, palish and clothed with 

 yellowish-grey adpressed hairs on the margins, and in- 

 clining to orange on the caput. The clypeus is 

 somewhat steep, about equal to half the height of 

 the facial space, and the sides of the caput ai-e 

 dark blackish-brown, leaving a longitudinal, central 

 reddish orange-brown band tapering to the thoracic 

 fovea. 



The upper and hinder part of the thorax is 

 strongly suffused with brown, leaving broad but 

 irregular pale lateral margins ; there is a group of 

 strong bristles directed forwards from the margin 

 of the clypeus, and two or three more in the median 

 line behind the ocular area.
