Characterization of Species. 
The characters given for many of these species are so brief 
that it would be useless to try to form a key. Therefore we will 
give in summary what, from the descriptions, seems to be the 
chief characteristics. 
1. Papirius guttatus (Say). 
1821. Smynthurus guttatus Say. 
1859. Smynthurus guttatus LeConte. 
1873. Papirius guttatus Packard. 
1895. Papirius guttatus Dalla Torre. 
Prevailing color, yellowish-white. Head maculated. An¬ 
tennae, reddish-brown, hairy. Eyes black. Body, yellowish- 
white with numerous irregular spots disposed in bands; numer¬ 
ous sparse, white hairs; two tubercles each side of the middle of 
the body which are truncated at the tip; ventral part of body 
white. Spring, flesh colored. Length, 1.3 mm. Habits, 
“found under the bark of the long-leaved pine (P. palustris) in 
Georgia.” 
The chief characteristics of this species as given by Say, seem 
to be a prevailing color of yellowish-white with numerous, 
irregular, reddish-brown spots. Neither MacGillvray nor Har¬ 
vey have reported this species, and thus far we have only the 
original description. Perhaps this may be accounted for by the 
fact that it is a southern form, and probably with a restricted 
habit, since Say only mentions having found it under the bark 
of the long-leaved pine. The description is so very brief it 
would be hard to identify a specimen by it. P. guttatus is placed 
in this genus on account of the tubercles which are not found in 
the genus Smynthurus. 
2. Papirius novoeboracensis (Fitch.) 
1862. Smynthurus novoeboracensis Fitch. 
1873. Papirius novoeboracensis Packard. 
1S93. Papirius novoeboreacensis Harvey. 
1895. Papirius novoeboracensis DallaTorre. 
Prevailing color, dull brownish-yellow. Head pale. An¬ 
tennae nearly the length of the body, long and slender. Eyes 
black. Body but little broader than head, oval, slightly at¬ 
tenuated at its tip, with an impressed, transverse line conspic¬ 
uously separating the apex from the body. Legs light yellowish- 
brown in color. Length about 2 mm. Habits under rubbish 
and boards. 
The chief characters, as given by Fitch, which distinguishes 
this species, as a Papirius is. as he says, “the length beyond the 
elbow of the antennae being obscurely divided into three joints.” 
This point was definitely settled by Harvey who examined the 
type specimens and said that Fitch in his work had overlooked
