ClCINDELID^; 15 



(cf ) 16.0 mm.; width 5.4 mm. California (Mokelumne Hill, Calaveras 

 Co.), Blaisdell. 



Readily distinguishable from parvicollis, or any other of the more 

 southern forms of the group, by its smaller size, less elongate form, 

 still more finely punctured elytra and less evident sparse feeble 

 fovece; its more northern habitat, as a close ally of parvicollis, is to 

 be noted. 



Group V (lecontei} 



It seemed probable at first that the following species might be 

 the one described by W. Horn under the name fiichsi, but it differs 

 in many ways as will appear: 



Omus lacertus n. sp. Female very stout for the lecontei group, the 

 head and pronotum especially developed as in some of the Sierra forms, 

 moderately shining; head large though distinctly narrower than the pro- 

 thorax, strongly, rather coarsely rugose, the middle of the front nearly 

 smooth and with only infinitesimal and remote punctulation; labrum 

 medially produced and quadrilobate, the median sinuate part projecting 

 beyond the small adjoining lobes; antennae rather long and stout; pro- 

 thorax transverse, fully a third wider than long, widest near apical 

 third, but with the sides very evenly arcuate, strongly converging behind, 

 the reflexed lateral margins strong throughout, more rapidly oblique at 

 base, which it virtually attains; surface moderately and almost evenly 

 convex, deeply, vernacularly rugose, the anterior sulcus fine and deep, 

 the subbasal feeble, not quite attaining the sides, the median stria deep 

 and conspicuous between the transverse impressions; elytra oblong-oval, 

 two-thirds longer than wide, two-fifths wider than the prothorax, widest 

 at about the middle, gradually ogival thence posteriorly, subparallel 

 anteriorly to the gradually rounded and not very definite humeri; 

 punctures rather small, somewhat aciculate in form, widely separated 

 throughout, the foveae moderate and in two somewhat definite series; 

 hind tarsi but little longer than the tibise. Length (9) 18.5 mm.; 

 width 6.7 mm. California (Carmel, Monterey Co.), Fuchs. 



In comparing this with the female of fuchsi, as described by W. 

 Horn, a number of irreconcilable differences become apparent. 

 For example, it is said that the pronotum is flattened, the median 

 stria almost obsolete, the elytral humeri broad and distinct, the 

 greatest elytral width well before the middle as in lecontei and 

 the antennae rather short and slender in fuchsi. No one of these 

 characters can be observed in the type of lacertus.
