ARACHNIDA. 
Clementi (Am. Ent. i. p. 62) notes the occurrence of Qordius in a Spider j 
and Hagen {ih. p. 69) enumerates similar instances observed in Europe. 
ARANEIDEA. 
Theraphosides. 
Ausserer, in his Beitriige zur Kenntniss der Arachniden-Familie der 
Territellariae ” (Verh. z.-b.Wien,xxi. pp. 117-224, Taf. i),an exhaustive paper 
on the Mygalides {Thei'aphoses^ Walck.), gives an alphabetical list of 74 pub- 
lications, in which Spiders of this group are either specially or incidentally 
treated of ; also an analytical review of the 47 genera and subgenera of the 
author’s Theraphosoidce. Detailed characters are also given of the families, 
subfamilies, genera, subgenera, and 137 species referable to them, with a list 
of 37 additional species, described by various authors, but of which the sys- 
tematic position is uncertain. Although, perhaps, many of the author’s groups 
are scarcely entitled to generic rank, this paper is a bold and successful at- 
tempt to break up into useful working groups a now numerous and hitherto 
unwieldy family of Araneidea, Reference can only be made to the paper 
itself for the characters of the two families (and, indeed, for details generally), 
owing to their length and minuteness). 
The author divides the Theraphosides (= Tei'ntellaricBy Thor.) into two 
sections, comprising in section A the family Catadysoid<^, and in section B 
Liyphistioidce and Theraphosoidce (Thor.). This latter is divided into three 
subfamilies — Atypince (Thor.), JEriodontince, and Theraphosince. The Atypince 
consist of the genera Telecodon (Dol.), Calommata (Luc.), and Atypus (Latr.) j 
the Eriodo7itince, of Eriodon (Latr.) and Antrodioitus^ g. n., founded on a sin- 
gular Spider from Alabama, Mygale unicolor (Hentz). The Theraphosince 
(which include by far the largest number of the species of the Therap>hosides') 
are divided into two main gToups, -^pycephali and Tapinocephali. Each 
of these is again divided and subdivided into lesser groups. It will, however, 
be sufficient here to give the names of the genera included in each of these 
main groups. Of the yEpYCEPHALi are the genera Pachyloscelis (Luc.), Acti- 
nopus (Perty), Closterochilus, Tlm'agretes, 3Iadognatha, Chorizops, Cyclocosmuij 
and Pachylomerus, gg. nn., Idiops (Perty), Idiosoma and AEpycephcdtis, gg. nn., 
Cteniza, Latr., Hexops and Cyrtocarenum, gg. nn., and Cyrtauchenius (Thor.). 
In the Tapinocephali are included Nemesia (Sav., Aud.), Hexathele and 
Erachythele, gg. nn., Eipltira, Koch, Macrothele, Idiommata, Leptopelma, Isch- 
nocohiSj gg. nn. (this last is subdivided into subgenera Ischnocolus and Chceto- 
pelma), Cyclosternum and Crypsidromus^ gg. nn. (the latter divided into sub- 
genera Crypsidrornttsoxi^ Harpaxibius')yChcetorhomhus, g.n., JV’ecAowa (Koch), 
Scurria (Koch), Tapinauchenius^ g. n., Avicularia (Lamarck), Earpacticay 
Selenocosmiaf Acanthoscurria, gg, nn. (the latter divided into subgenera Acan- 
thoscurria, Mygalarachne, and Acanthopalpus'), Eui'ypehna (Koch), divided into 
subgenera Lasiodora (Koch), Lasiomemusy IIomoeo7nma, Eurypelma (Koch), 
Thet'aphosa (Walck.). To the above genera and subgenera are referred 137 spe- 
cies, among them Calommata sumatrana, Sumatra, Pachyloscelis picea, Brazil, 
Cteniza orientalisy Brussa, spp. nn., Hexops whitii=^ Cteniza hexops (White, 
Australia), Port Natal, Cyrtauchenius doleschallidLiidiC.
