the latter being denser than in punctulatus. Joints 2 and 4 of the antennse are 

 of equal length, 6 and 8 are equal and a little shorter, 3 and 5 nearly equal and 

 very distinctly longer; 7 shorter than 3 or 5, but longer than 6 or 8 ; 9 rather 

 longer than the three preceding united and evidently narrower than in punc- 

 tulatus. Length 4i mm. 



California. One example, seemingly a female, in the Horn col- 

 lection. 



5. E. collaris n. sp. — Form of punctulatus; black, prothorax dark rufous, 

 tibiae and tarsi paler. Head densely granulate, eyes rather small, separated on 

 the front by three times their vertical diameter; antennse (£) rather short, 

 joints 2-5 nearly equal, third and fifth a little longer, 6-8 shorter, the seventh 

 just visibly longer than the sixth or eighth, sixth and eighth scarcely longer than 

 wide; ninth fully as long as sixth to eighth united. Prothorax a little more 

 strongly rounded on the sides, and with the front angles more rounded than in 

 punctulatus; punctuation throughout nearly as in the latter species; pubescence 

 cinereous. Length 3.4 mm. 



California (Pasadena). 



Described from a single female specimen taken by Dr. Fenyes, in 

 whose collection the type remains. This species should be at once 

 known by its color if that proves constant, otherwise the very short 

 sixth to eighth joints of the antennse may be relied upon to distinguish 

 it from its allies, of which the smaller forms of punctulatus seem 

 nearest. The presternum is unusually long before the coxa?, being 

 fully equal to half the coxal diameter from front to back. 



6. E. alutaceus Lee. — Size of rather large mollis, but obviously narrower 

 than either that or punctulatus. Head finely granulate, prothorax scarcely visibly 

 so, elytra with simple, fine punctuation, except at extreme base, where it becomes 

 finely granulate. Prothorax distinctly transversely impressed across the middle 

 of the disk, the outline and angles nearly as in punctulatus. Joints 3, 4, 6 and 8 

 of antennse nearly equal, 5 and 7 a little longer, but the disparity is less marked 

 than in mollis and punctulatus ; 9 subequal to the three preceding. 



The type is said by LeConte to be a female, but this is by no 

 means certain ; indeed, I should rather think it a male, judging 

 from the parallel ninth antenna] joint and the prominent eyes, the 

 front barely twice as wide as the longest diameter of the eye, or 

 about two and one half times the width of the eye as seen from the 

 front. The sixth abdominal segment is feebly notched at the tip. 

 Tarsi quite stout for an Emobius. 



" California." Collected by Murray. 



7. E. crotcllii n. sp. — Similar in form to ahitaceus or very slightly more 

 elongate, prothorax plainly granulate, base of elytra just visibly so. Prothorax 

 narrower than in alutaceus and fully three-fourths as long as wide, obviously 

 narrower than elytra at base, the transverse impression feeble but traceable.
