NEW .SPECIES OF PAPIRIUS. 



lUSTUS WAISON FOLSOM, CAMBRIDGE, MASS. 



Pupiriiis hageiiii, n. sp. 



Head li'anslncent orange ochraceous, orange 

 around mouth ; eyes black ; a few stiff, white 

 bristles upon vertex and face. Antennae 

 nearly as long as body, orange, becoming 

 purplish on last two segments ; basal segment 

 naked; second four times the first in length, 

 a few hairs distally ; third equalling the 

 second plus one-half the fust, verticillate ; 

 terminal segment twice the basal, whorled 

 as usual. Thora.x yellow. Abdomen oval 

 in dorsal aspect, dark purple, almost black, 

 covering the sides and meeting the pale 

 ventral surface with a well-defined but zig- 

 zag margin; on posterior half of dorsum, a 

 yellowish brown pattern, very variable 

 (sometimes almost absent) but consisting 

 fundamentally of a median elongated mark 

 widening behind and one quarter the length 

 of the abdomen, lying between four rounded 

 triangular spots, the anterior pair of which 

 are inore or less three-lobed. These five 

 spots maybe separate, but the three anterior 

 usually unite into a figure having a large 

 posterior median lobe, three lateral lobes 

 and a large anterior median sinus; tht two 

 posterior spots may unite to form a long, 

 irregular crescent before the apex of the 

 abdomen; abdomen with a few short, white 

 bristles on apical half; many two or three 

 times longer upon the yellow anal tubercle. 

 Legs yellow, paler at base ; tibia spin\ ; claws 

 transparent, slender, rather straight, little 

 curved inside; superim- claw witli a sharp 

 tooth inside, one thinl from apex; second 

 tooth obscure, in the middle; inferior claw 

 two thirds the other in length, with one 

 stout, knobbed tenant hair, twice as lon<', 



fixed to its inner side except at the tip, uhich 

 is free. Fnrcula (TuUberg's name for the 

 spring) extending to mouth, stout, pale 

 yellow at base, becoming white distallv; 

 manubrium (basal segment) over two thirds 

 the denies (middle segments) in length; 

 dentes three times mucrones (apical seg- 

 ments), each dens with a row of long spines 

 on either side; mucrones cylindrical, apex 

 rounded, minutely serrate beneath; ventral 

 abdominal surface with an oval, yellow 

 swelling either side the manubrium and two 

 similar but much largerones placed obliquely 

 and anteriorly. Average length, 1.3 mm. ; 

 maximum, 1.5 mm. 



Described from over twenty specimens 

 collected by me in October and early No- 

 vember, 1895, at Arlington, Mass. This 

 active, tmcommon species occurred in pine 

 woods under damp, decaying twigs and 

 needles. 



Pa f if ins pi}u\ n. sp. 



Chestnut brown, except for white claws, 

 mucrones and bristles. Head paler; eyes 

 black; a few short, stiff bristles upon a 

 protuberance on vertex and down sides of 

 face. Antennae four-fifths the length of 

 body; basal segment stout, naked; second 

 four times as long, a few long hairs distally ; 

 third equalling the first two, with distal half 

 of seven false sub-segments and three less 

 evident, s\yollen terminal ones; each sub- 

 segment with a pair of hairs; a few hairs 

 near base of third segment; fourth equal to 

 basal, with short hairs. Abdomen ovate 

 dorsally, dilated at sides; dorsum darker, 

 with several long white bristles anteriorly
