the female just before, ” Tk. abbreviatus ", after, oviposition. In H. N.d. Arane'ides, Walckenaer says of Tk. onustus: ’’abdomine orbiculato-

trigono, postice latiore, bituberculato”. "L’abdomen est jaune,

court, tres-large a sa partie posterieure, qui est arrondie et a en-dessus deux tubercules”; and in Tabl. d. Aran, the description ofthe form of the abdomen is couched in the same words. (The figurein H. N. d. Aran, is miserable). Compare also the characteristicsof Walckenaer ’s ”2 e Race, les 2'rapizoides" , in Ins. Apt., I, p. 517.That the anterior side-eyes in TU. onustus are larger than the others,is nowhere stated in any of Walckenaer ’s earlier works, and his clas-sing, in Ins. Apt., loc. cit., Th. onustus among "les Trapdzoides”,which are said to be distinguished by that characteristic, was withouta doubt caused by his believing Th. Peronii Sav. et Aro. (whichmust not be confounded with the "Th. Peronii, Var.”, that we havecited in the Synonyms!) to be identical with Th. onustus: in Savi-gny’s figure in fact the anterior lateral eyes of this Th. Peronii areslightly larger than the other eyes.

Lepechin ’) has described a white crab-spider, which he foundin Siberia under the bark of trees, and which Walckenaek adducesunder his Th. onustus. Whether this spider, to which Gmelin 1 2 ) in 1788gave the name of Aranea alba , really belong to Th. onustus , appearsto me very uncertain, and I have therefore not accepted the name*albus ” for the species before us.

Thinking it probable, that Philodr. auro-nitens Auss. or Pli. ce-spiticolis Westr. (see above, p. 266) might be identical with Ph .variatus Blackw., I had sent a fullgrown male and female of theformer species to Mr Blackwall, asking for his opinion on it: he nowinforms me, that "Ph. auro-nitens appears to be distinct from Ph . va-riatus” , and I have therefore thought it safest to register these twoforms as separate species.
