their grooves deep, oblique, suddenly and acutely flexed beneath, 

 where 1 they form a dee]), transverse excavation in front of the 

 eyes; scape long, slender, slightly elavate, first joint of fuuide 

 equal to the four following, '2 7 short, club small, oval, pubes- 

 cent, annulated; first and second ventral segments longer than 

 the others, third and fourth short, fifth broadly rounded behind, 

 as long as the two preceding united; legs short, stout, femora 

 thick, not elavate nor toothed; tarsi dilated, spongy beneath, the

Dark reddish-brown, shining, thinly clothed with long yellow prostrate 

 hairs. Head and beak densely punctured. Thorax wider than long, 

 rounded on the sides, feebly constricted near tip, broadly rounded at base, 

 strongly but not very coarsely or densely punctured, without trace of 

 dorsal smooth line. Elytra wider than thorax, feebly emarginate at base, 

 sides feebly rounded, tips conjointly broadly rounded; disc somewhat 

 flattened, stria? well impressed, slightly punctured; intervals nearly flat, 

 punctate. Beneath strongly and densely, the last ventral more finely, 

 punctate. Length 4 mm. 



Plummer's Island, Md., May 13; one specimen beaten from 

 dead branch. The type and only other known specimen was taken 

 by Hubbard and Schwarz at ('apron, Florida, in April. 



Tribe VII. ERIRHININI. 



This tribe embraces a large group of small species having the 

 mandibles 3-toothed, separated by two notches, the middle tooth 

 more prominent; mentum small, not transverse; anteuual grooves 

 beginning at a distance from tip of beak and usually curving 

 obliquely downward ; scape of antennae long and slender, funicle 

 either G- or T-jointed, club oval, ringed, usually entirely sensitive; 

 metasternuni as long as first ventral segment; front coxa? con- 

 tiguous, hind ones widely separated, narrower on the outer side 

 and reaching almost to the elytral margin ; ventral segments un- 

 equal, the third and fourth united usually about equal to the 

 second or fifth; legs rather slender, femora not toothed (except 

 in Doi'i/toiinis) , tibia? truncate and usually mucronate at tip; 

 claws not or broadly toothed. Most of the species occur on plants 

 near water, though the larva 1 of some infest the seeds of sun- 

 flowers and other wild plants, few of them as yet being especially 

 injurious to the farmer. The tribe is represented in the Eastern 

 United States by 18 genera, which, for convenience of treatment, 

 are separated into four subtribes. 



The following are the principal papers treating of the North 

 American species of the tribe :
