apical half, very broadly truncate at apex, the apico-lateral serrules acute, about 

 three in number ; sculpture nearly as in pubescens, except that the disk is finely, 

 sparsely punctulate toward base, without trace of imbricate sculpture. Elytra 

 smooth, conspicuously pubescent; apical tubercles small and rather feeble,

It is probable that pubescens is the species identified as sericans by 

 Gorham in the "Biologia." 



Amphicerus Lee. 



This is a rather large and important genus among our bostrichids, 

 not at all closely allied to Apate as is said to be the case by Mr. Gor- 

 ham in the "Biologia," the two differing radically in the form of the 

 antennal club among other characters. The species known to me are 

 as follows : — 



Elytra deeply margined at apex 2 



Elytra not strongly margined at apex, smaller species, brown or testaceous in color, 

 with the sculpture toward the base of the pronotum less broadly granulose and. 



more nearly strigose , 7 



2 — Elytra 4-tuberculate at the summit of the apical declivity, less distinctly so in the 



female ; body generally black throughout 3 



Elytra bituberculate at the summit of the apical declivity, rudimentarily so in the fe- 

 male ; color dark brown, the elytra less coarsely punctate 6 



3 — Pubescence of the elytra wanting or not distinguishable under low power 4 



Pubescence of the elytra conspicuous but decumbent 5 



4 — Elytra of the female more elongate, distinctly more than twice as long as wide, 

 with coarse and close-set punctures. Southern Texas to Honduras. 



punctipennis Lee. 

 Elytra of the female distinctly shorter, about twice as long as wide, with smaller and 

 sparser punctures. Female. — Body cylindrical, black, polished and glabrous. 

 Head two-thirds as wide as the prothorax, with the eyes rather large, very Con- 

 vex and prominent; vertex transversely tumid and pubescent; sculpture 

 coarsely granulato-rugoee ; antennae as long as the width of the head, dark rufo- 

 piceous. Prothorax as long as wide, parallel and broadly arcuate at the sides, 

 narrowed and serrate at the sides anteriorly, the apex sinuato-truncate, with the 

 apical teeth small; surface coarsely asperato-granose anteriorly, smooth with 

 flattened contiguous tubercles posteriorly. Elytra more than twice as long as the 

 prothorax and a little wider, the punctures coarser and closer toward the sides 

 and strongly and coarsely confluent on the apical declivity; tubercles rudiment- 

 ary. Abdomen with whitish pubescence, minutely and densely punctulate, with 

 coarse punctures interspersed. Length 12.0 mm.; width 4.0 mm. Texas (Gal- 

 veston) maritimus, sp. nov. 



5 — Female. — Body very slender, cylindrical, shining, black with a feeble piceous 

 tinge. Head three-fourths as wide as the prothorax, the eyes very convex and 

 prominent; vertex moderately tumid, the surface granulato rugose with a smooth
