furcula of moderate length, dentes nearly four times as long as broad at base, with 

 hairs beneath, mucrones about one-third the length of dentes, serrate below, tip 

 down-curved. Length, 2 mm. 



Among dead leaves in \vood.s, Sea Cliff, N. Y. Known by banded 

 legs, and mottled abdomen. 



Smynthurus argenteornatus, sp. nov. 



Pale; head with various pale brown markings, but obscure, more prominent be- 

 tween antenntE, and one larger near each eye : antennae pale, dark on apical joint ; 

 legs pale, the tibiae sometimes brownish ; abdomen pale on base, darker on apical 

 half, often the distinction veiy marked ; the basal part, however, has brown marks and 

 lines ; on each side are about six silvery white spots or patches, venter pale, ana- 

 tubercle when fully marked shows a pale round spot each side above ; furcula pale, 

 dentes rather darker. Antennae of moderate length, basal joint a little longer than 

 wide, second not twice as long, third nearly twice the length of second, fourth longer 

 than others together, with about l8 annulations ; abdomen of usual shape, not elon- 

 gate, broader behind, hairy above ; furcula moderate, dentes fully three times as long 

 as wide at base, a few hairs below, mucrones about one-third the length of the deutes, 

 slender, serrate below, and down-curved at tip. Length, 1.8 mm. 



In woods, on ground. Sea Cliff, N. Y. Differs from S. sylvesiris 

 in pale color, unbanded legs, silvery spots on sides, and longer third 

 joint of antennte. There is a form which I take to be but a variety of 

 this species, variety albesc€7is. Pale whitish or greenish, eyes black, 

 antennce dark except basal joint, silvery spots on sides show in fresh 

 specimens. Does not differ in structure from the type, except pos- 

 sibly a slightly shorter third joint of antennae. It occurs only in a 

 moss {^Polytrichiiin co/n/nii/ie^. 



Smynthurus dorsalis, sp. nov. 



Head pale, faintly lined with reddish, sometimes showing a more distinct reddish 

 band connecting bases of antenna;, eyes black ; antenna; pale on basal joints, last joint 

 dark ; abdomen pale yellowish, but with many fine blackish marks on sides becoming 

 closer behind and extending farther on dorsum till they meet somewhat before tip, 

 where it is black ; this leaves a pale broad dorsal mark, [rather sharply outlined be- 

 hind, but not in front, anal tubercle dark ; legs and furcula pale, venter pale, dark 

 marks on basal part. Head rather large ; antenna; arise directly in front of eyes, first 

 joint nearly one-half as long as second ; third is one-half longer than second, fourth 

 longer than second and third together, at first simple, then with i8 annulations ; legs 

 short ; abdomen nearly twice as long as broad, with scattered hairs above, more 

 numerous behind and on anal tubercle ; furcula short, manubrium short, dentes nearly 

 twice as long, tapering, with a few hairs below, mucrones short, about one-third the 

 length of dentes, covered at tip, serrate below. Length, 1.5 mm. 



In woods, Sea Cliff, N. Y. Recognized by pale dorsal area.
