Characterizatiox of Species. 



The characters given for many of these species are so brief 

 that it would be useless to tr}' 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. Smynthurns guttatus Say. 



. 1859. Smynthurus guttatus LeConte. 



187.3. Papirius guttatus Packard. 



1895. Papirius guttatus Dalla Torre. 



Prevailing color, yellowish-white. Head maculated. An- 

 tennae, reddish-brown, hairy. Eyes black. Body, vellowish- 

 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 tiomcated 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 bv Sav, 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 onlv the 

 original description. Perhaps this may be accounted for bv 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 ^•ery 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. Smvnthurus novoeboracensis Fitch. 



1873. Papirius novoeboracensis Packard. 



1893. 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 o\'erlooked
