D i a g n o s i s: Among the 2 heretofore known species of Agnatis   OPITZ, A. curvabilis   most closely approximate A. variabilis   OPITZ, from which A. curvabilis   specimens differ by showing an ovoid hind body.

D e s c r i p t i o n: Size: Length 9.0 mm; width 4.0 mm. Form: As in Fig. 279 View Figs 278-281 . Color: Cranium bicolored, frons, region behind eye, and gular region testaceous, epicranium and venter sides black; antenna, scape black; prothorax bicolored, venter brown; pronotum mostly testaceous, with narrow black vitta at middle; elytra testaceous; pterothorax brown, legs mostly testaceous, femora infuscated distally; tarsi black; abdomen with transverse brown and testaceous lines. Head: Cranium finely punctate; antenna ( Fig. 36 View Figs 28-42 ) capitate, funicular antennomeres gradually wider from pedicel to 8 th antennomere, capitular antennomeres 8 and 9 triangular, antennomere 10 ovoid; eyes small, ommatidia small, ocular notch large, eye much narrower than frons (EW/FW 25/50). Thorax: Pronotum ( Fig. 172 View Figs 171-178 ) transverse (PW/PL 130/120), anterior transverse depression absent; disc coarsely punctate, lateral sides convex, disc concave paralaterally; elytral asetiferous punctures absent, setiferous punctures small and profusely distributed throughout elytral disc (EL/EW 380/140); Abdomen: Pygidium scutiform; aedeagus as in Fig. 214 View Figs 213-218 .

Variation: Length 7.0-10.0 mm; width 3.7-5.0 mm. This species is highly variable in color. The dorsum may be almost entirely black with only the epipleura testaceous, or the dorsum may be nearly entirely testaceous with only the elytral apex slightly black. The mostly dark elytra may have a green iridescence.

N a t u r a l H i s t o r y: The available specimens were collected during June and July. One specimen emerged from wood of a species of Lonchocarpus HUBER (Euphobiaceae). They were also collected on blossoms of Casearia tremula   (GRISEB.) GRISEB. Ex WRIGHT ( Salicaceae   ), on a species of Coccoloba P. BROWNE ( Polygonaceae   ), and on the branches of a species of Acacia MARTINS ( Fabaceae   ). Altitudinally, these beetles were collected from 300 to 2100 m, with blacklights and mercury vapor lights.

D i s t r i b u t i o n: This species is known from Mexico and Guatemala.

E t y m o l o g y: Thetrivialname, curvabilis, is a Latin name with a meaning of "bent"; with reference to the curvature of the side margins of the elytra.
