arcuate, obsolete medially, ending laterally in a short, acute horn above 

 and behind each eye. 



Pronotum margined anteriorly and laterally, convex, with a broad 

 anterior process extending over the head almost to posterior edge of 

 clypeus. Process with base and bifurcating arms somewhat thicker 

 than in typical orpheus, the process bifurcating over the posterior part 

 of the vertex, the ends of the bifurcations thickened and rather 

 hatchet-shaped; process curving evenly downward, similarly as in 

 typical orpheus, when viewed laterally. Pronotal surface with 

 numerous coarse punctures usuall}^ separated by less than 1 diam- 

 eter, most punctures with a small tubercle at their anterior margins; 

 most punctures, including those on the central part of the disc, with 

 long, erect, conspicuous setae that gives the pronotum a much more 

 distinct "hairy appearance" than the other subspecies of orpheus; 

 surface between punctures smooth and shining, laterally with some 

 very minute secondary punctures. 



Elytra with well-defuied, slightlj^ impressed striae; all intervals 

 except the sutural interval and the anterior portion of the second and 

 fourth intervals irregularly biserially punctate-tuberculate, the punc- 

 tures minute and bearing long, erect, conspicuous setae; surface be- 

 tween tubercles mostly smooth and shining, not alutaceous. Pygidium 

 coarsely, setigerously punctate; medially with fine secondary punc- 

 tures and a few coarse ones, particularly posteriorly. Midhne of 

 metasternum very slightly impressed. Abdominal segments coarsely 

 shallowlj^ punctate laterally, the punctures becoming obsolete me- 

 dially; last segment emarginate medially to receive pygidimn. Legs 

 as described for the male majors of the typical orpheus (p. 47). 



Male minor. — Paratype, length 6.0 mm., width 3.6 mm. Dif- 

 fering from the male major in the following respects : Ch pens reflexed 

 only slightly more anteriorly than laterally, truncate at anterior edge, 

 not emarginate; clypeal carina slightly higher than that of male major 

 but of same general shape; carina of vertex only vaguely indicated 

 medially, raised laterally in a thin bladelike, sharply arcuate ending 

 above and behind the eyes. Pronotal protuberance still forming a 

 short, flat shelf that extends over the posterior part of the vertex and 

 is deeply emarginate medially (indicative of bifurcation of male major) ; 

 other male minors lack the pronotal projection, having only a vague 

 median hump that does not extend over the anterior margin. Legs 

 as described for male minor of typical orpheus. 



Allotype. — Female, length 6.5 mm., width 4.0 mm. Differing 

 from holotype male major in the following respects: Dorsal color 

 almost entirely green; clypeus rather evenly arcuate, shallowly 

 emarginate anteriorly, and faintly to moderately reflexed ; disc coarsely, 

 rugosely punctured, much more so than in male. Both carinae
