BEETLE GENUS ONTHOPHAGUS — HOWDEN, CARTWRIGHT 113 



hairy appearance, from the long yellowish seta at posterior edge of each 

 tubercle. Elytral striae black, usually shining, distinctly but not deeply 

 punctate; intervals flat and alutaceous between small, shiny tubercles 

 which are usually arranged in very irregular double rows, except on 

 sutural interval; posteriorly each tubercle with a long, yellowish seta 

 at its base, coloration uniform, no spots being evident in any of the 

 specimens examined. 



Pygidimn alutaceous and finely punctate over basal half, shiny 

 over slightly convex apical half with rather coarse punctures, all the 

 punctures, both basally and apically, bearing long, yellow setae. 

 Ventral surfaces usually brownish black with only a trace of the dorsal 

 blue or green; stem of antenna dark reddish brown with club grayish 

 brown. Anterior coxae more rounded and not as transverse as in 

 hecate, their anterior surface appearing finely rugose. Metathorax 

 laterally coarsely punctate, each puncture bearing a long, reddish- 

 yellow seta, the surface between the punctures finely alutaceous; 

 midline smooth, impunctate, anteriorly forming a vague ridge. 

 Abdomen, excluding the first segment, with a regular line of very 

 small, setigerous punctures running completely across the base of each 

 segment, the last segment emarginate as is typical in males of the 

 genus. Forelegs elongate, the apical end of the forefemur extending 

 slightly beyond the lateral margin of the thorax; foretibia very long 

 and sUghtly curved with an apical conical projection over the tibial 

 spine, the spine thickened and abruptly recurved at apex. Middle 

 and hind femora with scattered, coarse punctures, each bearing a 

 long seta, 



Male minors. — Length 5.5 to 7 mm,, width 3.3 to 4 mm. Differing 

 from male majors in the following respects: Clypeus rather evenly 

 rounded, reflexed upward anteriorly only slightly more than laterally; 

 disc evenly, rugosely punctate, with punctures bearing short setae; 

 clypeal carina more pronounced than in male major but of more uniform 

 height and extending completely across the posterior margin of the 

 clypeus; area between the clypeal carina and the frontal carina smiilar 

 to that described for the male major; frontal carina evident through- 

 out its length, but highest laterally, where it forms a small horn at 

 each end, a few scattered setigerous tubercles behind the carina; genae 

 only very slightly produced laterally, the margins protruding only a 

 short distance beyond the clypeal margin. 



Pronotum less convex but with tubercles and setae similar to male 

 major, margin generally similar in outline but without smooth concave 

 area in the anterior angles, the protuberance often indicated by only 

 a slight anterior median swelling, the swelling sometimes dehmited 

 laterally by smooth anteriorly directed humps.
