tullgren: two new species of chelonkthl 155 



Orange county in Florida collected from under bark by Dr. 

 Einar Lönnberg (Vu, ^Vio 1892). 



It is with some hesitation I give this Atcinnus as a species 

 new to science. I can not deny that the likeness between this spe- 

 cies and At. nidificator Balzan is very great. By when com- 

 paring with this species - we find first of all that the length of 

 the body of my species is greater. Céphalothorax is not smooth, 

 but wrinkled as by CJiclifcr robustus Balz., Ch. argcntimis 

 Thor, and several others. So are also the abdominal segments. 

 The five first of these always are more or less entire. The four 

 first only are by At. nidificator entire. Some small traces of 

 division may be seen on these five segments by certain speci- 

 mens, by others, on the contrary, not at all. As to the pedi- 

 palpi Balzan says they are by his specimens »un po' striate)-. 

 I have only found them very finely punctuated or totally smooth. 

 Tibia is by At. ßoridaiins a little longer than femur; by At. 

 nidificator these joints are said to be of equal in length. The 

 proportions of manus and digiti respectively seem to me in some 

 way difterent, digiti thus being shorter than manus by At. 7izdi- 

 ficator than they are by my species. Concerning the galea there 

 is an unveniable, though may be important, difference between 

 the two species, which is most easely seen from the figures. 

 Flagellum, Balzan says, consists of »quattro setole»; by At.flori- 

 danus I have generally found only three setae, of which the 

 anterior one both in the number and the size of its teeth difters 

 from the corresponding organs by At. nidificator. 



Chelifer (Chelanops) patagonicus n. sp. 



The body brilliant. Céphalothorax and pedipalpi dark brown. 

 Dorsal segments dark olive-brown, each segment with a darker 

 spot. The interspaces and the middle furrow light yellow. Ven- 

 tral segments paler. Legs yellow-brown.
