TRIBE X. - MAGDALIXI. 253 



Key Largo, Florida. A Cuban species which occurs sparingly 

 in southern Florida. Scluvffer suggests that possibly rur 

 and HH'I/I are the same. 



III. Ooi-TERixrs Casey. 1S92. (Gr., "egg" + "wing.") 



This genus differs from ()ti<!o<-c/>Ji(ilnx in having the eyes very 

 small ; elytra ovate, rounded on the sides, widest a little before 

 the middle, gradually narrowed and acutely rounded behind; 

 humeri obsolete, scutellum wanting. 



370 (8609). OOPTERIXUS PERFORATTS Horn, 1873, 451. 



Elongate-oval. Brownish-piceous. shining, antennae and legs still paler; 

 upper surface with sparse, rather short, semi-erect whitish setge. Head 

 sparsely, coarsely punctate and with a small, rounded frontal fovea. Beak 

 rather stout, feebly curved, about as long as thorax, coarsely and irregular- 

 ly punctate. Thorax obovate, longer than wide, strongly narrowed toward 

 base, very coarsely, deeply and densely punctate. Elytra two-thirds longer 

 than wide, with rows of very fine distant punctures; intervals with minute, 

 distant pum-tures. each bearing a slender, white, recurved hair. Femora 

 "broadly emarginate near apex, not toothed. Length 3.3 3.7 mm. 



Deer Park. Maryland, April I. Pennington Gap, Ya.. June 

 27. Clayton, Georgia, July. Recorded also from Pennsylvania, 

 Towa, Michigan and Cincinnati, Ohio. The elytra are sometimes 

 pale reddish-brown. "Fts being pallid, only suffused with piceous, 

 and entirely apterous, point strongly to a subterranean habit, 

 probably living on bulbs or other roots." (Hamilton.} Breeds 

 in cynipid galls on roots of oak. ( Pierre.) 



Tribe X. MAGDALINI. 



The members of this tribe differ from all others having the 

 front coxa' contiguous by the hind angles of thorax being acute, 

 prominent and more or less produced over the base of the elytra. 

 In addition, they have the beak slender, cylindrical, as long as 

 thorax; antennal grooves reaching the lower edge of the eyes 

 which are rounded and distant from the thorax; antenna* usually 

 inserted near the tip, male, or about the middle, female, slender, 

 feebly elbowed; scape slender, slightly clavate, curved near the end 

 and usually reaching the eyes; elytra oblong, subdepressed, widely 

 separated at base by the scutellum, separately rounded at tip ex- 

 posing part of the pygidium ; ventral segments unequal, first and 

 second long, connate, 3 .1 short, equal; front coxa* contiguous. 

 prominent; middle and hind ones not widely separated, the latter 

 small, oval; femora not club-shaped, sometimes toothed; tibiie
