Walckenaer's Th. triste (Ins. Apt., II, p. 291) is an entirely 

 different and much larger species, which, in spite of Dufour's pro- 

 test 1 ), I consider to be identical with Th. dispccr Duf., of the ge-

1) Descr. de deux nouv. especes- d'Aran., in Ann. de la Soc. Ent. de France, 

 3 Ser., Ill (1855), pp. 12, 13. — Of a spider which I take to he the same as Th. 

 distpw Duf. and Phmrolithus lunatus C. Koch, 1 met with a couple of females 

 under stones at Nice. It is much larger than Th. triste Hahn, with which it has 

 scarcely anything else in common than a for the most part hlack colour. It is on 

 the contrary nearly related to Lith. corollatus, from which it however may be 

 easily distinguished by a somewhat different colour, thicker mandibles, almost par- 

 allel maxillae etc. The following description of this species will not be out of 

 place here: Long, corporis 10 mm -; cephalothoracis 4 mm -; rat. maxima cephalotho- 

 racis 3y 4 mm -, long, abdom. 7, lat. ejus 5 3 /4 mra -. Cephalothorax inverse ovatus, la- 

 teribus partis thoracicae minus fortiter rotundatis, fovea ordinaria pone centrum 

 sita (inter coxas 2^ et 3 ti; paris), parte cephalica magna, versus frontem lateri- 

 bus rotundatis angustata, fronte rotundata, paullo plus l mm - lata. Altitude clypei 

 dimidiam mandibular longitudinem sequat. Desuper visi, oculi 4 antici lineam re- 

 curvam, 4 postici lineam rectam formant; medii aream fere exacte rectangulam , 

 vix longiorem quam latiorem occupant; medii antici, tuberculo communi impositi, 

 posticis paullo minores sunt et spatio oculi diametro majore inter se distantes. 

 Oculi laterales spatio parvo disjuncti, non contingentes , antici eorum ab anticis 

 mediis spatio vix minore remoti, quam quo distant hi inter se. Mandibular latitu- 

 dine basali fere duplo longiores, ad basin crassitie femoris (latit. earum communis 

 paullo plus l 1 /2 nim 0> cylindrato-conicas , versus apicein extus sub-sinuatae, setis 

 paucis longis prope apicem lateris exterioris; apice truncato, longius setoso, dente 

 intus armato. Maxillae magnae, labio plus duplo longiores,- ad basin angustse, 

 extus latae, lateribus exterioribus leviter rotundatis, parum inclinatis, lateribus 

 interioribus ad labium sub-emarginatis et fortiter inclinatis , supra labium autem 

 sub-rectis, parallelis; apice conjunctim rotundatae, pro se quaeque oblique rotnn- 

 dato-truncatae. Labium transversum, ad basin latius, lateribus leviter rotundatis, 

 apice rotundato-truncato , in medio transverse impressum. Pedes prop. 1, 4, 2, 3, 

 i™ paris cephalothorace 4pio longiores (c:a 16 mm -), 4 tJ his i j^m. breviores, 2d> 

 paris c:a 11 l / 2 mm -, 3*" c:a 9V2 rara - longi. Femora anteriora 4 mm - longa, versus 

 medium paullo incrassata. Patella lmi paris (supra) l 3 /i mm -, tibia Z 1 /^™-. Tibiae 

 posteriores apicem versus paullulo incrassatae. Abdomen altum (c:a 5 mm -), con- 

 vexum, forma ut in L. corollato. — Color niger, sub-piceus, hoc praesertim in femo- 

 ribus ad basin. Abdomen nigrum, fascia vel linea albido-flava, recurva, semicir- 

 culata in declivitate antica, et maculis aliquot sub-triangulis ejusdem coloris, plus 

 minus distinctis, seriem secundum medium dorsi formautibus. — The <J is not known 

 to me. Whether the spider, which Dufour described and figured (Descr. et rig. de 

 quelques Arachn., in Ann. d. Sciences Nat., II (1824), p. 210, PL 10, fig. 6) as <J 

 of his Th. dispar (ibid., p. 209, fig. 4). really belong to that species or not , appears 

 to me uncertain , since it is stated to have the 4 ltl pair of legs longer than the 1 st .
