 former distinctly longer than wide, the latter slightly wider than long, 

 eleventh conoidal and acuminate as long ;is the two preceding together;, 

 labrum nearly four times as wide as long, truncate at apex, sides parallel. 

 Prothorax slightly wider than the head; about on -fourth wider than long; 

 sides nearly parallel and feebly arcuate, more strongly so anteriorly; base 

 slightly wider than the apex, broadly and evenly arcuate; the latter broadly

 punctate. Abdomen short and broad, very slightly narrower than the elj-'tra; 

 sides parallel; surface minutely, feebly and very sparsely punctate; boder 

 very deep, vertical, thin. Legs slender; first joint of the anterior and mid-

California (Sau Francisco, 1). 



The ligula is deeply bilid, the mentura transversely trun- 

 cate, the third joint of the maxillary palpi being feebly swol- 

 len and longer than the second. The species is described 

 because of its departure from the normal European forms, in 

 that the second antennal joint is distinctly shorter than the 

 third, and the first joint of the posterior tarsi but slightly 

 longer than the second.
