the snlcas distinct, narrow and rather abruptly formed as in perexilis 

 and ending behind in the same small deep fovea which is not wider 

 than the salens itself; scnteliar granules not parted along the middle; 

 eljrtra longer and much broader but otherwise nearly similar, broadly 

 and obsoletely impressed behind the scatellum, the punctnres very 

 fine, only moderately sparse, becoming close-set, larger and more 

 asperulate near the inner basal angles; abdomen distinctly narrower 

 than the elytra, parallel with evidently arcuate sides, the sculpture 

 close- set but fine and feebly asperulate, the first impression with very 

 few obsolescent coarser punctures, the second and third impunctate; 

 hind tarsi much shorter than the tibiae. Length 1.65 mm.; width 

 0.42 mm. New York (Catskill Mts.),— H. H. Smith.. hndsonica n. sp. 



P(irexilis is one of the smallest falagrioid species known to 

 me within our faunal limits, but is more than equaled in this 

 respect by some of the forms of Melagria and greatly sur- 

 passed by the next genus ; it was found in some abundance 

 by Mr. Wickham. Hudsonica is represented at present by a 

 single specimen. 



Anenrota Csy. 



In its short tarsi, with more abbreviated basal joint than in 

 liny other tj^^e of the Falagriae now known to me, depressed 

 and parallel form, large quadrate head, peculiarly impressed 

 along the median line, short bristling hairs along the sides of 

 the body and some other characters, this genus is wholly iso- 

 lated in the present subtribe. That it belongs here, however, 

 seems to be evident because of the very narrow neck, but I 

 have been unable to break out the anterior coxae in the unique 

 type and am therefore not positive concerning the structure 

 of the concealed part of the prostemum. From glimpses 

 between the anterior parts of the coxae in a strong light, with 

 high magnifying power, it would seem that corneous plates 

 exist under the latter and that they are slightly incomplete or 

 rounded on the median line anteriorly, leaving a minute tri- 

 angle of membrane exposed. A more detailed statement of 

 its characters may be found under the original description — 

 Ann. N. Y. Acad. Sci., VII, p. 347. The type may be de- 

 scribed as follows : — 



Form depressed, parallel, shining, dark piceous in color, the abdomen black, 

 the legs pale testaceous; pubescence sparse; head large, parallel aid
