as the thorax, humeri obtuse ; disc moderately deeply striate, strise crenately 

 punctured, intervals slightly convex, very minutely sparsely punctate. Body 

 beneath sparsely, abdomen more closely punctate. Mesosternum alutaceous and 

 sparsely punctate. Anterior tibise smooth in front, tridentate externally and 

 crenate above, the first tarsal joint shorter than the second. Posterior femora 

 very sparsely punctate and finely alutaceous, the first tarsal joint nearly as long 

 as the next three. Length .26-.28 inch ; 6.5-7 mm. 



Male. — Spur of anterior tibia stout, strongly arcuate. 



Female. — Spur slender and feebly arcuate. 



This species is larger than eitlier of the preceding with niacuhxte 

 elytra, and is not as dai'k in color on the thorax or l)eneath. The 

 inner three stride reach the tip of the elytra and are not united with 

 the outer stria?. 



The nmculation of the elytra is never distinct, but it presents the 

 same style as has l)een described for pardalls. The same style of 

 arrangement of darker spaces may be observed in aleutus, in which, 

 however, they are more diffused. 



Occurs in Maine and eastein Canada. 



A. iiiiitilis u. sp.— Oblong, moderately robust, piceous, sides of thorax paler, 

 elytra dull red, legs yellowish. Antennae pale, the club darker. Head moder- 

 ately convex, sparsely punctate, front not tuberculate, but with the frontal suture 

 slightly elevated ; clypeus hemihexagonal, very feebly emarginate in froiat with 

 rounded angles, the gense scarcely prominent, very obtuse. Thorax convex, 

 slightly narrowed in front the sides feebly arcuate, hind angles very obtuse, base 

 arcuate, with fine marginal line, disc sparsely finely punctate with coarser punc- 

 tures intermixed along the base and at the sides. Elytra a little wider at base 

 than the thorax, humeri distinct, sides parallel, striae moderately deep and rather 

 coarsely crenately punctate, the intervals slightly convex with a single series of 

 very fine punctures. Body beneath very indistinctly punctate, abdomen rather 

 coarsely punctate at the sides. Mesosternum opaque and strigose at middle, 

 coarsely punctate at sides, not carinate between the coxae. Anterior tibiae smooth 

 in front, strongly tridentate externally, but not crenate above, the first tarsal 

 joint shoi-ter than the second. Posterior femora with extremely few punctures, 

 the first four tai-sal joints decreasing gradually in length, the first being shorter 

 than the next two together. Length .14 inch ; 3.5 mm. 



The two specimens before me have the anterior tibial spur slender 

 and acute, they are probably females. 



This species is small and inconspicuous in its characters, those 

 given in the table are the more conspicuous. The comparative short- 

 ness of the first joint of the hind tarsus will readily distinguish the 

 species from any other in the group. 



Occurs at San Francisco, Cal., and in Oregon. 



A. piiiiiilus n. sp. — Oblong, convex, parallel, piceous or nearly black, side 

 of thorax indefinitely paler, elytra yellowish, the sutural interval, oblique stripe, 

 lateral space and subapical spot piceous, legs yellowish testaceous. Antennre tes-
