Jensen-Haarup, New species of Coleoptera from West Argentina. 551 



Smaller (3^2 ^^)' Thorax narrower, more cordiform, stronger 

 constricted at base and with considerably more rounded sides ; 

 anterior angles strongly rounded, not prominent at all. Antennae 

 shorter and more robust (middle joints not twice as long as 

 broad). In other respects like B. Rijei and together with this 

 species. 



Patria : Prov. Mendoza (Argentina) ; not rare. 



B embidium Byei § n. sp. 



Length of body : 4^/2 mm. 



Shape : Head narrower than thorax. Thorax much wider 

 than long, considerably narrower than elytra, somewhat narrower 

 at base , with sharply right-angled (90 ") hind angles and with 

 moderately rounded sides ; anterior angles rather prominent. Elytra 

 oblong-oval, with moderately rounded sides. 



Sculpture : Frontal furrows single, parallel, flat and not deep. 

 Thorax with double, impunctate basal furrows, of which the most 

 sidewards is the longest and finest (but sharpest defined) and 

 laterally limited by a fine keel. Elytra finely punctate-striate ; 

 Striae disappearing towards sides and apex. 



Colour : Entire surface of body uniformly metallic black, with 

 aeneous reflection. Antennae, palpi and legs pitchy red ; femora 

 and aipcal joints of antennae darker. 



Patria : Prov. Mendoza (Argentina) ; not rare, together with 

 the preceding. Dedicated to my English entomological friend, 

 Mr. B. G. R y e , Copenhagen. 



B embidium paravarium n. sp. 



Note: Allied to B. dubium and B. Rtjei, but elytra variegated 

 with yellow. 



Length of body : 4^/^ — 5 mm. 



Shape: Almost in airrespects like B. Ryei, but anterior angles 

 of thorax rounded and not prominent. 



Sculpture: Frontal furrows single, rather deep and broad, 

 converging in front. Basal furrows of elytra double; the most 

 sidewards of these furrows fine and linear but sharp and placed 

 close to side margin, laterally limited by a fine keel ; the inner- 

 most one much larger, rounded and deep ; median line of thorax 

 strongly impressed behind. Elytra finely punctate-striate; striae 

 of equal strength down to apex. 



Colour : As in B. Ryei, but elytra speckled with yollow spots 

 almost as in the palearctic B. variim, conseqiicntly the luetallic 

 black colour very much predominating. 



Patria : Prov. Mendoza (Argentina) ; very fcw specimens.
