antennal tubercles and the margins of the eyes ver}' promment (in 

 most specimens of gloriosa this carina is almost obsolete) ; genae 

 posteriori}' bounded bj' an obscure carina (in gloi^sa the genae are 

 distinct ty rounded posteriorly) ; thorax with only an inconspicuous 

 scutellar scale and no carina anterior to it (in glonosa the thorax 

 with an irregular transverse carina just anterior of the scutellar scale,, 

 the latter broad and prominent) ; second abdominal tergite very 

 coarsely and deeply punctate (in gloriosa moderately and shallowly 

 punctate) ; pygidium very prominently longitudinally striate (in 

 gloriosa irregularly rugose) ; body and legs blackish (in gloriosa red).

 tergite with long, erect, yellow pubescence, abdomen from apex of 

 segment two with black pubescence. Length, 13 mm. 



Head black ; mandibles acute at the apex, bidentate within near the 

 tip: clypeus bidentate medially at the apical margin, closely and 

 finely punctate, clothed with long, erect, black pubescence; scape 

 punctured, clothed with sparse, erect, black pubescence ; first segment 

 of flagelium distinctly shorter than the second ; antennal scrobes dis- 

 tinctly carinate above; front with close, shallow, more or less con- 

 fluent punctures, clothed with long, rather dense, erect, black pubes- 

 cence; the vertex similarly punctured but the pubescence mostly yel- 

 low; genae with close, shalloAv more or less confluent punctures, 

 clothed with long, erect, black pubescence; relative widths of head 

 and thorax, 7-10. 



Thorax black ; anterior margin of prothorax broadly and shallowly 

 emarginate medially, the cephalic surface of the emargination gla- 

 brous, impunctate ; pronotum, mesonotum and scutellum and metano- 

 tum closely, more or less confluently, and shallowly punctured, 

 clothed with long, dense, erect, yellow pubescence; propleura with 

 large, very shallow, more or less confluent punctures; mesopleura 

 with large, shallow punctures, those of the anterior half separated, 

 those of the posterior half more or less confluent, clothed with sparse, 

 erect black pubescence ; metapleura glabrous, impunctate on the dor- 

 sal half, closely, shallowly j)unctate on the ventral half, clothed with 

 sparse, erect, black pubescence: sides, dorsum, and posterior face of

 black pubescence; tegulae blackish, glabrous, the basal and lateral 

 margins closely punctate, clothed with long, j^ellow pubescence. 



Abdomen black; first segment subnodose; first tergite closely and 

 confluently punctured, the punctures smaller and closer on the apical 

 third, clothed with long, erect, black pubescence; the second tergite
