TWO NEW SPECIES OF CHELONETHI (PSEUDO- 

 SCORPIONS) FROM AMERICA. 



By ;^LBERT JULLGREN. 



Atemnus floridanus n. sp. 



The whole body very brilliant. Céphalothorax and abdominal 

 segments red-brown, the latter often paler. Pedipalpi dark red- 

 brown, cheliceres paler. Legs brown-yellow. 



The breadth of céphalothorax is about 3 quarters of its 

 length, its foremost part rounded without furrows, but the chiti- 

 nous scale has very fine transversal wrinkles, or strije, is thinly 

 clothed with very long simple to a little toothed hairs. Length 

 1,05 mm., breadth 0,35 mm. 



Eye-spots two, situated at the base of pedipalpi. 



Dorsal segments of abdomen wrinkled. The five first ones 

 entire, the back-edge in the middle a little incised, the five following 

 distinctly divided by a length-furrow; the last entire. All those 

 in the back-edge with long simple — slightly toothed hairs; 

 those of the last abdominal segments very long. 



Cheliceres very long. Galea at the head more or less bent 

 outward with 6 (by one examined specimen 5) branches, which 

 are nearly straigth. Flagellum consists generally of 3 set«, the 

 first is the greatest and has 8 or 9 teeth along the fore-edge; 

 these teeth are straight — a little ascending, those in the middle 

 are the longest (up to thrice as long as the breadth of the prin- 

 cipal stalk). The other two setae are shorter, entire and slightly 

 curved. By one examined specimen I have seen three simple setae.
