low; occipital foveas near the middle of the length, and mutu- 

 ally twice as distant as either from the eye; sulcus obsolete 

 near the frontal tubercle, the middle part of the vertex very 

 convex. Antennce as long as the head and prothorax 

 together, the two basal joints stouter; seventh and eighth 

 slightly larger than the preceding; ninth and tenth increasing 

 in length and twice as wide as long; eleventh slightK- wider 

 than the tenth, twice as wide as long, and equal in length to 

 the threa preceding joints, ovate, acuminate. Prothorax 

 slightly wider than long, slightly wider than the head, widest 

 before the middle, broadly arcuate to the neck, sinuate behind, 

 base three-fourths of the greatest width; disk convex, trans- 

 verse sulcus deep, posteriorly angulate in the middle, where it 

 is deeper; lateral fovese small, pubescent. Elytra^ across the 

 prominent shoulders, slightly wider than the prothorax, suture 

 one-half longer than the prothorax; sides slightly arcuate, 

 depressed, sutural lines arcuate, discal ones one-third the 

 length, wide at the base; intermediate basal puncture very 

 small. Abdominal segments widest at the base, diminishing 

 in width, the three basal ones each with two carinas.

E. DECORUS, Casey. Reddish brown, elytra, legs, and 

 antenuEe, j-ellowish red, polished, translucent; pubescence 

 short, fine, inconspicuous. Length 1.4 mm. 



Head large, slightly longer than wide, tempora as long as 

 the large eyes, slightly arcuate, convergent, frontal margin 

 arcuate anteriorly, depresssed in the middle, supra-anlennal 

 tubercles large, rounded, prominent; vertex fiat above, decliv- 

 ous on the sides, elevated far above the eyes, sparsely punctu- 

 late; there are two pubescent, circular, foveas in a line with 

 the posterior margin of the eyes, mutually one-half more 

 distant than either from the eye; sulcus very convergent, thin, 

 and obsolete anteriorly. Antennce very short, slightly longer 

 than the head, second joint sub-globular, thicker than the first; 

 the other joints transverse; the tenth more than four times 

 wider than long, lenticular; the last as long as the four pre-
