across the dorsum; broadly rounded on the front margin; the disc polished, deeply 

 rather coarsely and closely punctured; the smooth median line faintly indicated, 

 distinct only on the middle third; the lateral callus feebly indicated; the trans- 

 verse, subbasal, arcuate impression very faint; the basal median prominence 

 distinctly compressed as usual; the pubescence very minute. The meso-sternum 

 is oblique between the coxae. 



The elytra are more than one-third longer than wide; with the base arcuate, 

 elevated and finely crenulate as usual; the striae on the disc moderately narrow, 

 distinctly wider than in dentatus and canadensis, with the punctures distinct 

 and wider, but the strige narrower and the punctures smaller than in pimctatus; 

 the striae moderately impressed, more strongly than in dentatus, less so than in 

 canadensis; the lateral striae widely and deeply impressed only near the side 

 margins; the discal interspaces rather wide, distinctly outcurved towards the 

 base, the second moderately widened basally; moderately convex, the last three 

 on the sides very strongly convex; coarsely not very closely granulate-punctate, 

 with a few transverse rugosities near the base and uniseriately finely serrate near 

 the declivity; the declivity closely and roughly punctured; the first and third 

 interspaces moderately elevated, each with a regular row of small, blunt, moder- 

 ately close serrations; the second as wide as the first or third, not narrowed 

 towards the tip, nearly flat, closely roughly punctured; the outer interspaces 

 finely rather closely serrate, the fourth hardly serrate, the ninth carinate to the 

 apex; the pubescence yellow, minute and almost invisible except on the declivity 

 where it becomes much closer and minutely scale-like. 



This species resembles punctatus in many respects, but has the elytra! 

 punctures smaller, the interspaces a little more closely granulate, the second 

 interspace on the declivity as wide as the others, and the pronotum more 

 sparsely and coarsely punctured. The mesonotum is oblique in the few speci- 

 mens examined, and it is therefore placed in the cristatus group. 



Described from five specimens: Scaffold Meadow, Tulare Co., Cal., 

 Juniper, Hopping. Two of these have the dechvital serrations noticeably 

 coarser and sparser and may possibly be the males; there is no decided 

 frontal or pronotal differance. 



Phloeosinus juniperi, n. sp. 



A species of moderate size, hitherto confused with dentatus; readily dis- 

 tinguished from dentatus by its larger size, (usually), the more coarsely and more 

 sparsely punctured frontal disc, with usually strongly developed carina and lateral 

 calli, the coarser strial punctures and the oblique mesosternum. 



Description of the female. — Length, 3- 8mm.; width, l-7mm. Relative pro- 

 portions: pronotum, width 41, length 30; elytra, width 43-45, length 60. 



The head has the front plano-convex, with a broad transverse postepistomal 

 impression, the median carina and epistomal median lobe nearly obsolete; very 

 densely, coarsely granulate-punctate; the eyes deeply, broadly emarginate; the 

 antennal club elongate with the sutures oblique; the pubescence fine and 

 indistinct. 



The pronotum is one-fourth wider than long, widest at the extreme base, 

 which is very slightly narrower than the base of the elytra; bisinuate behind; 

 the sides regularly arcuately narrowed from base to apex, except a faint con- 

 striction behind the front margin, the constriction distinct across the dorsum; 

 the front margin very broadly rounded; the disc brightly polished with the 

 punctures of moderate size and only moderately close, with traces of irregular 

 rows in front; the median carina distinct except in front, sHghtly elevated and 

 shining, widest on the median third; without a distinct subbasal, arcuate, 

 transverse impression; with a polished lateral callus on each side behind the 

 middle, midway between the median line and the lateral margin; the pubescence 

 very fine, short and indistinct.
