punctured, and with a large broad black mark in the middle, the base being rounded ; 

 the arese obsolete. Petiole smooth, shining, impunctate ; postpetiole shining, with a few 

 obscure punctures at the apex. Remaining segments of the abdomen punctured, pilose, 

 the pubescence on the apex being especially long ; on the second segment there is, at 

 the base, a broad black band, which narrows at the middle, then runs on either side 

 along the gastrocceli, the base of which is black ; on the third segment is a narrower 

 black band ; on the apical segments the basal band is obscure, if not obsolete, and the 

 apex itself is almost fulvous, smooth, shining, and almost impunctate. Gastrocceli 

 very broad, the bottom with large longitudinal striations ; sides smooth, impunctate. 

 Areolet 4-angled, triangular above. 



In some examples the black basal band on the abdominal segments is broad and 

 distinct on all the segments ; others have the apex of the posterior tarsi black, and the 

 line on the metanotum frequently small and obscure.

Hab. Guatemala, San Geronimo {Champion). 



Body covered with a short pubescence. Head and thorax closely but not deeply 

 punctured, the former excavated above the antennae, and with the vertex in the middle 

 broadly, and the greater part behind, black. Mesonotum covered with a black pubes- 

 cence, more or less blackish, especially in the centre, and semiopaque. Scutellum 

 gibbous, broadly rounded at the base, narrower at the apex, the sides above margined. 

 Metathorax with two large, acute tubercles ; the sides projecting at the apex (which 

 has a slight slope), thus making the centre hollow ; the arese obsolete, the surface 

 subrugose. Petiole yellow for the greater part, smooth, shining, and with a longish 

 hollow on either side at the apex ; postpetiole punctured, the apex in the middle smooth, 

 shining, and impunctate. Gastrocceli deep, aciculated, double as wide as long, and 

 situated quite close to the base of the segment. Abdominal segments punctured, covered 

 with a close pubescence ; at the base of the third segment there is a small black mark, 

 narrowed in the centre ; a broader and wider mark on the next segment, a longer and 

 narrower band on the following, and a shorter and broader one on the apical segment, 

 all black. The apices of the wings are faintly clouded ; the areolet sharply triangular 

 above ; the nervures black.
