the former resembles it rather closely in this respect. The following 

 species belongs near calif ornicus Horn: 



Mycetophagus provensis n. sp. Elongate, parallel, convex, distinctly 

 shining throughout, piceous, the elytra each with four spots of paler 

 tint as in calif ornicus, except that the anterior spot is larger, enveloping 

 the entire humeral angles and extending along the base half way to the 

 middle of the scutellum; pubescence short, subdecumbent, not very dense; 

 head scarcely more than half as wide as the prothorax, punctured and with 

 very deep epistomal suture, the eyes only moderate but notably prominent; 

 antennae nearly as in calif ornicus; prothorax still shorter, distinctly more 

 than twice as wide as long, widest at the basal angles, the converging sides 

 evenly and moderately arcuate thence to the apex; surface nearly as in that 

 species, except that the sides are concavo-deplanate nearly throughout 

 the length; scutellum similarly transversely oval; elytra nearly as in 

 californicus in size and outline, but the serial punctures are rather larger 

 and better defined and the intervals rather less conspicuously punctulate; 

 under surface with the punctuation similarly dense but finer and less 

 granulose. Length (9) 4-3 mm.; width 1.75 mm. Utah (Provo), 

 Wickham. 



Resembles californicus closely, but differs in the rather smaller 

 though notably more prominent eyes and deplanate sides of the 

 pronotum; the very pallid color of the type is probably due to 

 immaturity, at least in great part. 



Litargus Erich. 

 Subgenus Litargellus Csy. 



This subgenus, or genus as it will probably be considered when all 

 the components of the Litargus group are more fully known, is 

 composed of small species of regularly oval, convex form and with a 

 complex design of pale and darker markings on the elytra. On 

 looking over my material again, it seems apparent that there are 

 more than the single type species, nebulosus Lee., and I would suggest 

 the following tabular arrangement of them : 



Prothorax black, nubilously pallescent near the sides; general color above, 

 beneath and throughout the legs black or nearly so, the elytra each 

 with a system of transverse pale markings which might be termed 

 trifasciate, the middle fascia on each directed posteriorly toward the 

 suture; punctures rather small, close-set and asperulate on the upper 

 and lower surface; pubescence stiff, reclining, less distinct beneath; 

 head with the coarse hairs directed outward from the median part, 

 the eyes rather small; antennae small, slender, the first joint of the 

 club as long as wide, with straight diverging sides, the second trans- 

 verse and the third truncate and shorter than wide; prothorax more
