BEETLE GENUS ONTHOPHAGUS — HOWDEN, CARTWRIGHT 31 



striae shining; strial punctures distinct, slightly crenating the intervals; 

 intervals flat with uTegular rows of widely spaced fine tubercles. 

 Pygidium alutaceous throughout, with scattered, moderately fine, 

 shallow punctures slightly closer laterally and apically. Ventral sur- 

 faces smooth and shinmg; mctasternum with very fine, scattered punc- 

 tm'es at middle and moderate pimctures forward and to sides; terminal 

 abdominal segment with a smgle transverse row of setigerous punc- 

 tures scarcely larger than those of the preceding segment; segment nar- 

 rowed apically to receive the pygidium. Forelegs slightly longer and 

 thinner than m the female. 



Allotype. — Female, length 8 mm., width 4.5 mm. Shining; bead 

 black in front of clypeal carina, green behind; pronotum dark bluish 

 green, elytra black. Clypeus narrowly reflexed anteriorly, gradually 

 less so to genae; broadly trmicate-emarginate at middle; disc moder- 

 ately, transversely punctate-rugose, most of the punctures anasto- 

 mosing and more or less indistmct; clypeal carina with narrow band 

 of close fuie punctures on anterior slope, carina almost angularly 

 higher at middle. Frons ciuite closely punctate, the punctures sepa- 

 rated by 1 to 2 diameters; punctm'es fine anteriorly to moderately 

 coarse at frontal carma; frontal carina weakly arcuate posteriorly, low 

 and sharp medially, elevated each side to a high, acutely tipped 

 tubercle; tips of the tubercles slightly nearer the middle than to the 

 edges of the eyes; occiput, moderately finely punctate, more coarsely 

 so around the tubercles to the eyes. Genae closely coarsely punctate, 

 many of the punctm'es anastomosing; margin evenly obtusely rounded 

 to clypeus with only a tiny notch marking the juncture. 



Pronotmn fuiely margined, faintly and very fuiely so basally; disc 

 strongly convex, a wide, vague prominence in front with a shallow ver- 

 tical concavity on each side; anterior angles not sharply rounded ; surface 

 everywhere with close mLxcd moderate and fine punctures, the moder- 

 ate pmictures separated by 1 to 2 diameters; surface otherwise smooth 

 except for very fhie alutaceous sculpture narrowly along the base. 

 Elytra alutaceous except at shoulders; striae shining and sparsely, 

 shallowly punctate; intervals flat, the first with one, the second with 

 two and part of a third, and the next four with two irregular rows of 

 fine tubercles, separated by four to six or more times their diameters ; 

 tubercles overhanging setigerious punctm*es but the setae so short as 

 to be almost invisible. Pygidium apically convex and shining, aluta- 

 ceous basally; scattered fine punctm*es becoming closer and deeper 

 apically. Ventral surfaces smooth and shining; metasternum with a 

 distinct, shallowly impressed midline, some fine scattered pmictures 

 at middle, and moderate to coarse punctures forward and to sides. 

 Abdominal segments finely alutaceous, each with transverse row of 

 very fine tubercles overhanging very fuie setae; setae relatively short
