Dark indigo blue throughout. Eyes (fig. 

 12) sixteen. Posl-antennal organs (figs. 13, 

 14) of four elliptical-oval elements. Anten- 

 nae shorter than the head, with segments as 

 5:8:7:10; basal segment globose, second 

 and third sliglitly expanding, fourth subcj- 

 lindrical with rounded apex. Body subcj- 

 lindrical. Superior claws (fig- 15) broad, 

 almost straight, untoothed ; inferior claws 

 of hind feet two fifths as long as the superiors, 

 slender, lanceolate, acuminate; of the remain- 

 ing feet, one fourth as long, small ; tenent 

 hair stout, exceeding the large claw, apex 

 bent. Manubrium as long as the rest of the 

 furcula ; denies (fig. 16) one sixth as long, 

 oblong, distally rounded, terminating in an 

 upturned tooth. Anal spines (fig. 17) two, 

 three fifths as long as a superior claw, stout, 

 feebly curved, erect ; upon contiguous papil- 

 lae. Clothing (fig. iS) of many stout curving 

 serrate setae of moderate length and fewer 

 long erect capitate setae, more or less serrate. 

 Length, 2 mm. 



This is the species that Packard redes- 

 cribed as nivicola Fitch. Packard's 

 specimens are not in the Museum of 

 Comparative Zoology, with the rest of 

 his Essex County material, but I am in 

 possession of his original drawings, 

 which leave no doubt as to what species 

 he regarded as nivicola. Harvey and 



Lintner depended upon Packard's 

 account of nivicola, and the specimens to 

 which they applied that name are, indeed, 

 the same species that Packard had in 

 hand ; this I have learned from an 

 examination of the identical specimens 

 that Harvey and Lintner used in prepar- 

 ing the papers mentioned above in the 

 synonymy. 



As I have good reasons (already 

 given) for believing that the nivicola of 

 Packard is not that of Fitch, and needs 

 a new name, I gladly name it packardi.

This species is frequentl)' found on 

 red maple trees, crawling on the trunk 

 or remaining under the bark or in crevi- 

 ces, especially about the base of a tree. 

 I have occasionally found it under the 

 bark of pine, oak, and apple trees, or 

 about the roots ; or clustered under moss 

 on a stone. Full grown individuals 

 occur from mid April until the middle of 

 June ; a second brood begins to appear 

 late in June and has disappeared by 

 the last of August. I have twice (April 

 22, 29) found abundant eggs of this 

 species under the loose moist bark of 

 red maple roots, protected by the sod ; 

 they were pale yellow, spherical, 135 

 micra in diameter, occurred in irregular 

 masses and hatched in a little under one 

 month.
