of Los Angeles, who has very kindly placed them at my dis- 

 posal. In one example the elytral vittae are almost entirely 

 wanting, in the others a little better defined. The antennal 

 club is relatively shorter than in any of our previously de- 

 scribed species. The shorter spur of the anterior tibia is 

 about three-fourths the length of the longer one, and this 

 seems also about the ratio prevailing in both diffracta and 

 crinita notwithstanding Casey's statements of existing dif- 

 ferences. 



Lachnosterna lenta n. sp. 



Oblong, scarcely wider behind, robust, not strongly convex, castan- 

 eous, legs paler. Clypeus feebly emarginate, border rather widely re- 

 flexed, surface moderately finely punctate, the punctures well sepa- 

 rated ; front similarly punctured, more sparsely at middle, in some 

 examples. Thorax obliquely narrowed in front, sides subparallel pos- 

 teriori}-, margin finely crenate, punctuation coarse, close, and nearly 

 evenly distributed. Elytral punctuation as coarse as or slightly coarser 

 than that of the thorax, and equally dense; sutural costa distinct, 

 discal costa faint but evident, marginal obsolete. Pygidium finely 

 sparsely punctate, nearly smooth in the female. Metasternum hairy in 

 both sexes, the hairs shorter and less dense in the female. Abdomen 

 minutely remotely punctate. Last joint of maxillary palpus elongate 

 fusiform, not impressed. Length 17-20 mm., width 10-12 mm. 



Male. Antennal club slightly longer than the entire stem ; pygid- 

 ium broader and evenly convex ; abdomen flattened at middle, the 

 penultimate segment with an arcuate or subangulate slightly rough- 

 ened ridge a little behind the middle; last ventral broadly concave, 

 smooth at apex ; inner spur of hind tibia short, one-third to two-fifths 

 the length of the outer one; ungual tooth smaller, acute, distinctly 

 intra-median in position. 



Female. Antennal club shorter tnan the stem ; pygidium smoother, 

 more narrowly rounded and slightly tumid at apex; inner spur of 

 hind tibia nearly as long as the outer ; ungual tooth larger, median. 



This species is a member of the ephelida group and should 

 stand between gcnerosa and praetcrmissa. It is closely re- 

 lated to the latter, differing in its rather more robust form, 

 * coarser, denser punctuation, somewhat more widely reflexed 

 clypeus, the thoracic margin more evidently crenulate. The 

 genitalia are quite distinct from the figures given by Smith, 

 for praetermissa, the male claspers more complex as viewed
