VI. Elytra Icevia. 



20. Strigoderma auriventris. (Tab. XIV. fig. 22.) 



Elongata, obloDga, fere tota glabra, polita, capite, tborace et scutello caaruleis, elytris nigris, subtus viridi-aurea 

 splendidissima, pedibus cyaneis, femoribus aureis vel rufo-aureis ; capite confluenter punctulato, vertice 

 kevi, clypeo brevi trapezoidali, angulis sat distinctis, margine reflexo antice medio minus reflexo subsinuato ; 

 tborace paullo ante medium dilatato, postice vix ampliato, angulis posticis subrectis, sulculo marginali 

 basi medio late interrupto, supra laevi polito, vix perspicue sparsim punctulato utrinque foveis tribus 

 laevibus partim confluentibus ; elytris striis omnibus (marginali recta mox a callo humerali incipient! 

 excepta) obsoletis, politissimis. Pygidium viridi-aureum, nitidissimum, punctulatum. Mesosternum 

 latissimum, apice tumidum nee porrectum. Tibia? postice elongatas, basi angustatae, suratae. 



Long. 14 millim. $ .

Two examples, females. This beautiful species differs but little in details of structure 

 from Strigoderma, although the peculiar sculpture, or lack of sculpture, and the 

 Butela-like coloration seem to indicate a different generic type. The membranous 

 border of the elytra is well-developed, and the antennae are 9-jointed, though the fifth 

 joint is much longer than any of the rest, and the mesosternal epimera are tumid at 

 the sides and strongly ascendent. The most important differences are in the labrum, 

 the visible basal part of which is longer than in the Anomalas generally, and has no 

 trace of median depression, but is straight and sharp-edged, and dips vertically in front 

 with its lower (or anterior) edge not visible ; and in the mentum, which is in the same 

 plane as the ligula and longitudinally concave.

This distinct genus consists only of one very variable species, apparently confined to 

 Mexico.
