160 NORTHERN ZOOLOGY. 



The description that Fabricius and Olivier have given of B. umbellatarum is so 

 extremely brief, that I am by no means certain that the insect I here give under 

 that name is really synonymous with it. As far as their description goes it corres- 

 ponds, and also with Olivier's figure, but that is very indistinct. It has been found 

 in Barbary, Portugal, and Provence. Fabricius says it affords no characters except 

 its colour and smooth elytra ; but it will be found upon a close inspection, I speak 

 with regard to the American specimens, to exhibit several. 



DESCRIPTION. 



Body black-bronzed, covered all over as it were with a fine net-work, produced by minute lines 

 as if scratched by a pin or needle ; above dull, below glossy. Antennae much shorter than the 

 prothorax : prothorax transverse with rounded sides, and longitudinal basilar impressions near each 

 posterior angle : scutellum triangular : elytra with three very slight impressions arranged longitudi- 

 nally ; an obsolete series of punctures runs parallel with the lateral margin ; apex obtuse and very 

 minutely serrated : presternum acuminate. 



xviii. * Subgenus Oxypteris. Kirb. 



Labium minute, subemarginate. 



Palpi last joint subcylindrical. 



Rhinarium indistinct. 



Nose with a sinus taken out forming the segment of a circle. 



Antennae as long as the prothorax, subsetaceous, subserrated internally. 



Body rough from numerous granules. 



Elytra diverging, very acute at the apex. 



Tarsi as in Trachypteris. 



The type of this subgenus is Buprestis appendiculata, it is principally distinguished from the 

 preceding by its longer antenna?, more slender towards the extremity, and by its very sharp elytra.
