150 SEKKICOENTA. 



Hab. Panama, Tole {Champion). 



This species is remarkable for its form, being almost equally narrowed in front 

 and behind, with the head very broad and the elytra acuminate, the greatest width 

 being at the middle of the latter. The head and thorax are finely reticulate-striolate. 

 The thorax is not much narrowed in front (as compared with allied species), with the 

 sides lightly transversely impressed in front and at the base. The elytra are purple, 

 with some very short pale pubescence, which forms a not very distinct fascia behind 

 the middle, and appears almost to cover the apex ; a few pale hairs are also visible 

 near the base. The terminal segment of the abdomen of the male has the apex very 

 broad, almost truncate, with the angles rounded, furnished with about twenty short 

 blunt teeth, one or two at the extremities of the series being small and not so well 

 defined as the others (fig. 16).

Hab. Guatemala, Cahabon, Chiacam, and San Juan in Vera Paz (Champion). 



This species has a short thorax and relatively long elytra. The greatest width is at 

 the juncture of the elytra and thorax; the width slightly diminishes to the middle of 

 the elytra, and then a little more obliquely to the apical truncature. The thorax has 

 rather large, very shallow punctures scattered over the surface and is sparingly pube- 

 scent. The elytra are punctured and are slightly rugose at the shoulders, with a 

 smoother patch between the pubescent bands, this smoother part being of a darker 

 colour than the rugose part ; there is a little pale pubescence in the basal region, and a 

 not very distinct narrow fascia at the middle — commencing from the margin it curves 

 upwards to near the suture and then turns obliquely downwards to the suture ; the 

 posterior fascia commencing from the margin is very slightly directed downwards, 

 then very slightly upwards, and then clescends again to the suture, this fascia being 

 more dense near the middle and at first sight appearing like an oblique whitish spot ; 

 there are a few pale hairs near the apex. The terminal segment of the abdomen of 

 the male is rather widely produced at the apex, widely but not deeply emarginate, with 

 a slight notch in the middle, nearly parallel at the sides, with two acute teeth on the 

 outer side at a lower level (fig. 17). 



The foregoing description is taken from a specimen from Cahabon. The example 

 from Chiacam is of a more brownish-brass colour. Four female examples from San 

 Juan are of a dark bluish-green.
