Vol. XXviii] ENTOMOLOGICAL NEWS 225 



macher, in Eldorado, Plumas, Del Norte, Humboldt, Placer, 

 Monterey, Shasta and Lake Counties, California, demonstrates 

 very clearly that aditlterina is the prevailing race of cordata. 

 The specimens collected in Del Norte County are on the aver- 

 age smaller than those collected elsewhere, otherwise they are 

 true adultcrina. The above series is augmented by 156 speci- 

 mens taken in Tuolumne and Mariposa Counties. 



Eleodes hybrida n. var. (A race of cordata Esch.) 



Prothorax as in cordata, except that the pronotal intervals are flat 

 and more or less alutaceous. The punctures are rather abruptly defined, 

 more or less coalescent and irregularly placed, leaving small and im- 

 punctate areas on the central part of the disk. The moderately deep 

 punctures give the intervals the appearance of being raised, although 

 not in the least rugose. 



Measurements. Alales — Length, 12.5-13.0 mm.; width 5.5 mm. Fe- 

 male — Length, 12.5-13.0 mm.; width, 6.0-6.5 rnm- 



Types in my own collection. Type locality, Plumas County. 



Habitat. — -Plumas and Lake Counties. F. W. Nunenmacher, 

 collector. Number of specimens studied, 55. 



In adulterina the prothoracic intervals are rugose as in cor- 

 data and the punctures finer. The first two joints of the pro- 

 tarsi at tips beneath, bear moderate tufts of piceo-flavate 

 pubescence, and the first joint of the mesotarsi has a small 

 transverse submarginal tuft at tip {$). 



Eleodes trita n. var. (A race oi farvicoUis Esch.) 



Opaque, sculpturing eroded, oblong-ovate. Thorax somewhat trans- 

 verse. Elytra depressed, humeri prominent and obtusely rounded. 



Head and antennae as in producta Mann. Pronotum less transverse 

 and less arcuate behind the middle than in producta; disk moderately 

 convex, more or less slightly impressed laterally, rather coarsely and 

 somewhat densely punctate, punctures shallow and eroded, denser 

 and finely granulate along the lateral margin, the sumfnits of the 

 granules bright and shining; apex, sides, base and angles as in pro- 

 ducta. Propleurae sparsely granulato-punctate and more or less 

 rugulose. 



Elytra about twice as long as wide, less elongate than in producta; 

 base truncate, distinctly wider than the base of the pronotum; sides 

 more or less arcuate and subparallel, becoming arcuately and some- 

 what convergent in apical third, apex rather broadly rounded; disk 

 distinctly flattened at base, thence more or less evenly convex, rather 

 obliquely and somewhat rapidly declivous posteriorly, arcuately rounded
