and differently impressed pronotum, black, feebly convex, shining; 

 head moderate, with very deep anterior impressions, the epistoma 

 and labrum broadly and feebly sinuate at tip; antennae piceous; 

 prothorax as in amethyst-inns, except that the external of the two 

 latero-basal impressions is not feeble and rounded but deep, elongate 

 and linear, with its external side cariniform, the angles nearly right 

 but slightly blunt, the inner longitudinal impression deep and strong; 

 elytra nearly three-fourths longer than wide, the sides parallel, 

 feebly arcuate, the striae fine, impunctate, feebly to strongly impressed 

 intero-externally, the intervals virtually flat to distinctly convex 

 correspondingly; humeri rather strongly denticulate; hind legs 

 missing in the type. Length ( 9 ) 12.5 mm. ; width 4.8 mm. British 

 Columbia. A single example sent by Prof. James F. Kemp. 



scenicus n. sp. 



Form still narrower and more elongate, smaller in size, strongly shining 

 and very pale yellowish-testaceous throughout in the type prob- 

 ably from immaturity, although the integuments are full and firm 

 and with no indication of distortion on drying; head three-fifths 

 as wide as the prothorax, the impressions fine, arcuate and diverging; 

 prothorax as long as wide, feebly convex, the sides broadly and 

 moderately arcuate, feebly converging but becoming not evidently- 

 more than straight basally, the angles slightly and minutely promi- 

 nent, sharp and right; base feebly sinuate medially, four-fifths the 

 maximum width; surface depressed and feebly rugulose between the 

 transverse impression and the base, with a larger feeble concavity 

 involving the latero-basal impressions, which are feeble, the inner 

 only a fourth the total length, the outer almost obsolete; elytra 

 elongate-oval, not evidently wider than the prothorax, broadly 

 rounded at the sides, rather acutely rounded at apex, three-fourths 

 longer 'than wide, the moderate impunctate striae rather deeply 

 impressed, the intervals feebly convex, strongly so laterad; humeral 

 denticle very small; scutellar stria long, joining the first stria at 

 a long distance behind the scutellum; legs moderate, the tibiae (cf ) 

 feebly crenulate within, the tarsi rather stout, the basal joint shorter 

 than the next two, grooved at the side, the second not grooved. 

 Length (cf ) 11.5 mm.; width 3.7 mm. California (Sta. Cruz Mts.)- 



arcanus n. sp. 



j? Body rather small in size and suboblong, feebly convex, shining, 

 piceous-black to black, the entire under surface, legs, antennae 

 and labrum piceo-rufous; head moderate, the impressions rather 

 shallow, diverging, the epistoma and labrum truncate; prothorax 

 slightly shorter than wide, the sides broadly arcuate, feebly oblique 

 posteriorly, becoming just visibly subsinuate near the angles, which 

 are more than right though minutely, subdenticularly prominent; 

 base feebly sinuate medially, margined laterally, the latero-basal 

 impressions moderate, the inner long but not very deep, the outer 

 small and almost obsolete; elytra oblong-oval, barely one-half longer 

 than wide, depressed above, strongly declivous laterad, with strong, 

 impunctate and deeply impressed striae and moderately convex in- 

 tervals, sometimes becoming nearly flat suturally; supplemental
