85 (- -). APIOX COXALE Fall, 1898, 134. 



Elongate, rather slender. Black, sometimes with a feeble greenish- 

 bronze lustre, finely and sparsely pubescent. Beak of male as long as 

 head and thorax, feebly curved, finely striate and punctate in basal two- 

 thirds, thence more finely punctate and shining to tip; of female longer, 

 more slender, very finely striate and punctate throughout. Thorax about 

 as long as wide, widest one-third from base; disc rather sparsely punctate, 

 its basal fovea elongate. Elytra not quite twice as long as wide, slightly 

 wider behind the middle in female; intervals feebly convex, less than 

 twice as wide as striae. Under surface rather sparsely punctate; side 

 pieces of meso- and metasterna clothed with white, scale-like hairs. 

 Length 1.92.1 mm. 



Ranges from District of Columbia and North Carolina to 

 Arizona and Lower California, and liable, therefore, to occur in 

 Southern Indiana. The only species known to have the front 

 tnbercnlate in male.

Moderately elongate, robust. Black, thorax opaque, elytra with pur- 

 plish-bronze lustre; basal joints of antennae reddish-brown; pubescence 

 fine and sparse. Beak, in both sexes, as long as head and thorax, dilated 

 about one-third from base; finely striate and punctate, tip polished. 

 First joint of antennae about equal to the next two, second reaching the 

 eye, 7 and 8 wider than long. Front strongly punctate. Thorax slightly 

 wider than long, base not much wider than apex, sides curved; disc very 

 densely and coarsely punctate, its basal fovea small, round, deep. Elytra 

 about two-thirds longer than wide, sides subparallel; intervals wide, flat, 

 each with a single row of minute punctures. Under surface densely and 

 rather coarsely punctate, side pieces of meso- and metasterna clothed as in 

 coxale. Length 2.2 2.4 mm.

 When the beetles were confined with the leaves they riddled 

 them with minute holes. A handsome and easily recognized 

 species.
