NORTH AMERICAN COLEOPTERA. 283 



lateral impression. Elytra widest in the middle, and one and two-thirds longer 

 than wide, shoulders high, prominent, their width as wide as the prothorax, tip 

 rounded, very broadly arcuate, nearly truncate. Pygidium triangular: meso- 

 thorax carinate ; first ventral twice as long as the second, the last longer and 

 convex in the 9 . short and concave in % .

As a sliglit return of favors received this is named in honor of 

 Capt. T. L. Casey. 



Seydnipeniis? ovithorax n. sp. (PI. IV, fig. 12),— Brown, impuuctate, 

 thinly pubescent. Length 0.8 mm. Head three-fourths width of prothorax, 

 nearly quadrate, the frontal margin tiipai-tite by short impressed lines, declive 

 anteriorly. Eyes brown (nyctalopical j very flat and small on the anterior part 

 of the sides and hardly to be discerned: antennal club 3-jointed. Piothorax 

 obovate. without any impressions and rounded sides. Elytra together elliptical, 

 shoulders obsolete, faintly depressed at the middle of the base of each elytron ; 

 sutural lines faintly indicated at the basal fourth, the posterior part seems to be 

 connate (wingless?); anterior cosse contiguous, posterior coxae small, mutually 

 remote, femurs clavate, pedunculate, compressed : ventral segment six, the last 

 very large, as long as the three preceding ones together. 



California, Santa Clara County. Ch. Fuchs. 



Like Scyd. minimus (PI. IV, fig. 13), this is a very doubtful Scycl- 

 mcEiivs, but I prefer to leave it there until similar forms are discov- 

 ered. 



Brachycepsis, of which I described B. Fnchsii (PI. IV, fig. 11) in- 

 cludes all Scydmseni with " colluni imersum thorace" of LeConte's 

 Synopsis and {teste Dr. Sharp) ought be retained in that new genus. 



EUTHIA Stephens. 

 Until the present day the genus Euthia was never discovered in 

 the United States of America. Our present species of the genus 

 Euthiodes, supposed to be Euthia, diflTer in the form of the maxillary 

 palpus, the third and fourth joint being united to a thick fusiform 

 body sharply pointed, the antennae strongly geniculate, the posterior 

 coxse mutually very moderately distant. Common with Euthia is 

 the general form with the head short, pronotum arcuate, quadrate, 

 edged on the sides, elytra finely margined, truncate or not covering 

 the pygidium. The species known, according to LeConte's Synopsis, 

 are : 



Elytra distinctly punctured, prothorax as wide as long, with five basal punctures. 



Length 1.0 mm. (Arizona) COloii Horn. 



Elyti-a faintly punctured, vertex foveate. 



Prothorax wider than long, with an abbreviated basal line. Length 1.1 nun. 



(Alaska, Oregon) scilula Maklin. 



Prothorax as long as wide, basal line entire, connecting three punctures (Cali- 

 fornia) inipressa. 



Prothorax longer than wide, basal line connecting five punctures (California).
