A. Jocosns n. sp. — Form elongate, rather slender, parallel : antennae nearly 

 as long as the head and thorax, brown, the basal joints testaceous, apieal joint 

 pale brown, joints 5-10 as broad as long; head quadrangular, black, shining, 

 coarsely not closely punctate, a small median smooth space ; beneath very sparsely 

 punctate; thorax scarcely wider than the head, oblong, very slightly narrowed 

 behind, sides slightly sinuate, surface coarsely not closely punctate, a narrow 

 median smooth space, color reddish yellow ; elytra nearly parallel, very little 

 wider, but distinctly longer than the thorax, color piceous, shining, apical margin 

 not pale, surface relatively coarsely and closely punctate, very sparsely pubescent: 

 abdomen reddish yellow, -the two apical segments paler; surface moderately closely 

 punctate, very feebly shining, sparsely pubescent; beneath as above; legs pale 

 yellow, metasternum piceous. Length .18 inch; 4.5 mm. 



Male. — Anterior tarsi moderately dilated ; last ventral segment with a small 

 triangularly oval emargination. 



Female. — Last ventral entire; anterior tarsi narrowly dilated. 



I have seen but two specimens of this species. It is hirgor than j^pc- 

 de.roides, the elytra longer and more coarsely punctured and without 

 apical pale border. 



Occurs in Delaware and North Carolina. 



A. jllClinclns n. sp. — Form, size and color of pcederoides, and differs by the 

 surface, especially the elytra more densely punctured and opaque, and the apical 

 pale border of the elytra broader, and gradually wider externally ; the head is 

 distinctly narrower behind the eyes. Length .14'inch; 3.5 mm. 



I have seen but two specimens, both apparently females. 



Occurs in South Carolina, and seems to be rare. 



A. eleganttllllS n. sp.— Slender, elongate, pale yellow; head and elytral 

 spot black, metasternum and tip of abdomen above piceous; antennae slender, 

 nearly as long as the head and thorax, piceous, basal joint paler,joints 7-10, nearly 

 as wide as long; head oval, distinctly narrower behind the eyes, shining, coarsely 

 punctate at the sides and beneath ; thorax not wider than the head, oblong, dis- 

 tinctly narrowed behind, sides sinuate, sparsely coarsely punctate at the sides; 

 elytra a little wider and longer than the thorax, longer than wide conjointly; sur- 

 face very shining, coarsely and sparsely punctate, very slightly pubescent; color 

 j'ellow, with an oval spot, black on each side, of variable size; abdomen shining, 

 very sparsely punctate, and with very little pubescence, terminal two segments 

 darker in color ; beneath shining, very sparsely punctate. Length .16 — .18 inch; 

 4 — 4.5 ram. 



Male. — Anterior tarsi slightly dilated ; last ventral with a broad, but not deep 

 oval emargination. 



Female. — Anterior tarsi feebly dilated ; last ventral entire. 

 A pretty species, easily known by its very sparsely punctate surface, 

 and by the elytra almost entirely yellow. 

 Occurs in southern California and Arizona. 



A. terminalis Lee. — Form slendei*, pale reddish yellow, head, metasternum^ 

 elytra in part, and last two segments of abdomen black; antenniB pale brown^ 

 nearly as long as the head and thorax, joints 6-10 as broad as long; head quadrate
