28 MEMOIRS ON THE COLEOPTERA 



surface rather sparsely punctate, more densely and slightly more 

 coarsely laterad, having an impressed longitudinal line at the middle; 

 elytra at base slightly narrower than the thoracic base, gradually 

 widening toward apex, the three costae distinct, feebly convex and 

 very finely, irregularly punctate; subsutural and second intervals 

 with a more irregular row of coarse punctures than those of the 

 geminate rows enclosing the costae; at the sides the punctures form 

 almost regular rows; pygidium convex, rugose, sparsely hairy at tip; 

 under surface coarsely punctate; metasternum with a few erect 

 hairs; front tibiae with a single external tooth, the apical process 

 elongate, curved; inner claw of the anterior tarsi (cf ) very feebly 

 cleft, the upper portion extremely slender and short, that of the 

 intermediate tarsi scarcely visibly cleft. Length 7 mm. Arizona 

 (Bakersville?) clypealis Schf. 



Clypeus transverse, moderately arcuate at apex, with broadly rounded 

 angles and sides that either diverge slightly or become parallel 

 basally; size not so small 13 



13 Basal bead of the pronotum entire but extremely fine and depressed 

 slightly below the general surface. Body almost evenly elongate- 

 oval, convex, rather shining, pale brownish-flavate aboveand beneath, 

 the head dark brownish-rufous, the pronotum at apex with a large 

 medial spot of dark brown, which is prolonged posteriorly along the 

 median line, generally in a narrow line, the elytra with the suture and 

 outer edge, sometimes very broadly toward tip, piceous or blackish; 

 head rather shining though densely but not coarsely punctato- 

 rugulose, the eyes very moderate, not differing much sexually, 

 separated by three times their width; clypeus rather broadly and 

 strongly reflexed, obsoletely at base, where the sides become parallel; 

 antennal club (9 ) small, as long as the five preceding joints; pro- 

 thorax distinctly less than twice as wide as long, the sides rounded, 

 converging apically, the basal lobe broad and rather feeble; basal 

 angles broadly rounded, the apical sharp but more than right, the 

 sinus shallow; punctures minute and very sparse throughout; elytra 

 slightly elongate, rounded apically from slightly behind the middle, 

 very feebly inflated medially, only slightly wider than the prothorax, 

 having regular and evenly spaced rows of rather strong punctures, 

 coarser laterad, where the rows become somewhat impressed, the 

 second interval broad, confusedly and strongly punctate, broadly 

 basally, more narrowly posteriad; pygidium convex, shining, hav- 

 ing the short arcuate scratches feeble and sparse. Male with 

 the upper ramus of the inner anterior claw very short and slender, 

 the female with the inner claw cleft at apex, the lobes subequal, the 

 upper projecting evidently beyond the lower. Length (cf 9 ) 

 7.8-9.0 mm.; width 4.2-4.5 mm. Lower California (Santa Rosa). 

 Four examples centralis Lee. 



Basal thoracic bead not so fine and always interrupted medially 14 



14 Eyes in the male only moderately prominent, more widely separated; 

 elytral punctures deeper and more conspicuous 15 



Eyes in the male very convex and prominent, separated by about twice 

 their width; elytral punctures feeble and rather indistinct 16
