33-i [June 20, 



Horn] L 



late, middle and posterior tibiae biseriately spiuulose. Length .10 inch ; 

 2.5 mm. 



The rather coarsely denticulate tibiae and fimbriate margin ally this 

 species to some of the following groups. The middle tibiae are also 

 more coarsely spiuulose than is usual in this or any of the preceding 

 groups. 



This species appears to be rare in California. 



Group VII. 

 Prosternum narrow, acute at summit, striae almost entirely lateral, 

 strongly divergent anteriorly, ascending, terminating in a shallow de- 

 pression. Thorax with margins fimbriate in nearly all the species. 



This group and the preceding are very closely allied, and it becomes a 

 matter of difficulty with some of the species of both groups to decide to 

 which they should be referred. It is probable that a more natural 

 division would be into those which have, and those which have not the 

 margins of the thorax fimbriate. In the event of such a division of the 

 groups, neglectus and rubriculus should enter the preceding, and ciliatus 

 removed from it. 



With the exception of two unique types before me, all the species are 

 represented by good series of specimens, and an amount of variation is 

 seen leading to the belief that were similar series collected of all the 

 species, the number of our Saprini would be reduced fully one-half. 



A study of the material before me has resulted in the following table, 

 which I believe exhibits the forms which are entitled to rank as 

 species : 

 Prothorax with margins not fimbriate. 



Prosternal striae well-marked, fossae simple , neglectus. 



Prosternal striae feeble, fossae linear uniting at the summit 



of the prosternal carina in front rubriculus. 



Prothorax with fimbriate margins. 



Elytra with smooth scutellar space, sometimes well-limited. 



Third dorsal stria entirely obliterated vitiosus. 



Third dorsal normally developed. 



Scutellar mirror distinctly limited behind. 



Interstrial spaces densely punctured lubricus. 



Smooth space at the base between striae 2-4 plenus. 



Scutellar mirror not well defined, punctures diffuse. 



Third dorsal attaining the base of elytra fimbriatus. 



Third dorsal abbreviated at base acilinea. 



Elytra punctured over the entire surface which is opaque. 

 Color, bluish ; elytra less densely punctured iu the sub- 



scutellar region coerulescens. 



Color, brownish ; elytra equally densely punctured vestitus .
