a basi ad apicem sensim pallulo incrassata, pene 4- plo 
longior quam latior ; prope apicem lateris exterioris, supra, 
dente sat parvo sed forti, paullo deorsum curvato, anteriora 
versus et paullo foras directo armata est, cujus apex in duos 
dentes acuminatos est fissus. 
“ Pars tarsalis—pene triplo longior quam latior, ad formam 
ut in A. dimidiato, modo apice paullo breviore. Bulbus a 
latere exteriore visus paullo ante medium subter rotundato 
excisus videtur, ita ut dentem deorsum et anteriora versus 
directum hic formet pars excisa, que supra, antice, in pro- 
cursum sat brevem et latum, apice dilatum, porrectum (non 
ut in priore specie profunde bifurcatum) producta est. 
“Ceph. in fundo luteo-ferrugineo, pube densa flava et 
rubro tecto, itaque flavo, pictura rubra. 
“ Abdomine in fundo subtestaceo, secundum medium 
dorsi late flavo, pube flava, intermixta rubra, que maculas 
saltem ad partem in ordines duos longitudinales dispositos

Dr. Thorell says of this, the type of a new genus, ‘¢ unicam 
feminan nondum adultam, detritam et valde mutilatam (pedi- 
bus plerisque carentem) hujus aranee vidi.” 
It is much to be deplored that an experienced arachnologist 
like Dr. Vhorell should take a much mutilated specimen, an 
immature female, and one which has lost several legs, as the 
type of a new genus. 
New Species of Ctenus. 
I hesitate to attempt to draw up a synoptic table of species 
without more material to substantiate my conclusions as to 
specific differences. The form of the vulva is, however, the 
only really reliable character, and of this portion of structure 
a figure has been given.
