398 Goleopterological Notices. 



E. estriatus n. sp. — Moderately robust, strongly convex, smooth and 

 highly iwlished, the pronotum very slightly alutaceous. Head rather trans- 

 verse, moderate in size, rather coarsely punctate, the punctures sparse toward 

 the middle, very dense and setose laterally ; antennae rather short and robust, 

 the third joint very slightly longer than the next two together, fourth less 

 than twice as long as wide. Prothorax just visibly wider than long, the apex 

 truncate, equal in width to the base which is subtruncate ; sides broadly 

 arcuate anteriorly, convergent and nearly straight in basal half, the basal 

 angles very obtuse and not at all prominent ; disk moderately convex, very 

 finely and sparsely punctate throughout. Elytra about three times as long as 

 the prothorax, widest behind the middle and about two-fifths wider than the 

 prothorax, at base equal in width to the base of the latter, the humeri not 

 rounded but also not prominent ; apex acute but not greatly prolonged ; disk 

 moderately declivous behind, finely but distinctly and very sparsely punctate, 

 the punctures not asperate, not denser laterally and arranged without trace 

 of order throughout. Length 17.8-26.0 mm. ; width 6.5-9.7 mm. 



California (San Francisco). 



The two specimens before me differ very greatly in size but are 

 exactly of the same form, the legs, however, in the small specimen, 

 are relatively longer and more slender than in the larger one, in 

 which they are unusually short and robust when compared with 

 longicoUis or giganteus, to which this species is allied. It differs 

 from the former in its broader more anteriorly dilated prothorax, 

 much shorter and rather more robust antennaa and coarser punctua- 

 tion, and from the latter in the smaller size, less attenuate form, 

 wider epiplcura?, less convex pronotum, less arcuate sides of the 

 prothorax, shorter elytra and many other characters. In giganteus 

 the elytra are generally but slightly less than four times as long as 

 the prothorax. 



The anterior tibial spurs in estriatus are rather slender, similar 

 and very slightly unequal in length ; in the larger specimen they 

 appear to be relatively a little longer. I am therefore uncertain as 

 to whether the two specimens are both males or both females, or 

 whether the smaller is a male the larger a female ; I am inclined 

 however to think that the latter may be the case as if my memory 

 is correct they were taken at the same time. 



Although giganteus is said by Horn (Rev. Ten., ]>. 312) to occur 

 near San Francisco, I have never found it in that locality, but have 

 it from San Diego which is also the locality assigned it by LeConte 

 in a penciled note. LongicoUis does not occur within the true 

 Pacific coast fauna.
