indistinctly so, the surface alutaceoiis. Posterior femora coarsely and rather 

 closely punctate. Tarsi brownish, the first joint of the posterior tarsi as long or 

 longer than the next three. Length .22-.24 inch ; 5.5-6 mm. 



Of this species I have seen but two specimens only one of which 

 is now before me, it shows no sexual characters. 



The spinules of the apex of the hind tibiae are very plainly unequal. 

 The mesosternum is coarsely punctured in front, not carinate betw^een 

 the coxse. 



This species resembles lutulentm in form, but is more obtuse poste- 

 riorly. 



Occurs in California and Vancouver. 



.4. lultileiitus Hald. — Oblong, moderately elongate, black, subopaque. An- 

 tcnnse ferruginous, club piceous. Head densely puuctulate with feeble traces of 

 frontal tubercles in the male. Clypeus broadly but feebly emarginate at middle, 

 strongly angulate or subdentate each side, sides of clypeus arcuate with a distinct 

 sinuation at the end of the frontal suture, gente prominent, but obtuse. Thorax 

 convex, gradually narrower to front 9 or with the sides parallel and arcuate 

 near the front angles % , hind angles very obtuse, base arcuate, but slightly sin- 

 uous, disc convex, feebly shining % or opaque 9 i the punctures rather fine, very 

 dense over the entire surface 9 oi" spar.ser at middle % . Elytra not wider than 

 the thorax, oblong oval gradually narrowed to apex, humeri slightly dentiform, 

 disc striate, strife punctured, intervals flat opaque, longitudinally strigose with 

 moderately coarse punctures which are often submuricate or granular. Body 

 beneath more shining than above, sparsely punctate. Mesosternum opaque and 

 strigose, not carinate between thecoxfe. Hind femora coarsely sparsely punctate. 

 First joint of hind tarsus not longer than the next two. Length .22-.28 inch ; 

 5.5-7 mm. 



Male. — Spur of anterior tibia very long, equalling the first four tarsal joints. 

 Upper spur of middle tibia very short and obtuse. Posterior edge of hind femora 

 very broadly and obtusely angulate, the posterior tibise rather broad and thin, 

 the lower face smooth the transverse ridges very feeble, one only being at all 

 indicated. 



Female. — Anterior tibial spur of normal size. The posterior femora of normal 

 form, the tibiai rather slender, the ridges indicated, but feeble. 



The females are of smaller size and more opaque than the males, 

 the thorax more narrowed in front and more densely punctured. In 

 this sex I have observed specimens without the emargination of the 

 clypeus and consequently without trace of angulation, but these may 

 be distinguished from stupklm by their larger size and the more pro- 

 longed elytra. 



At the time of my former synopsis this w-as one of our rarest spe- 

 cies and the female was apparently the only sex known and for this 

 reason the curious male characters escaped observation.
