narrowly reflexed ; surface with distinctly impressed longitudinal stria, which 

 are on the disk, especially near base, punctate ; intervals flat, more or less 

 convex near side and towards apex ; the transverse lines almost entirely ab- 

 sent on the disk but present at sides and at apex, tegulae at sides and apex 

 formed by the transversely impressed lines elongate, but shorter and some- 

 what acute or graniform at apex. Length 13 mm., width 7 mm. 



California (coll. O. Dietz). 



This species belongs to liixatum and allies and is principally dis- 

 tinguished from any of those known so far by the distinctly striate 

 elytra. 



Pterostichus caligans, Horn. 



I received lately a specimen of this interesting species. By its 

 large head, etc., it resembles Pt. grandiceps more than any other spe- 

 cies and ought to be associated with it and not with Pt. angustus. 



Family EROTYLID^. 



Scaeother opacus new species. 



Black, opaque, below piceous, tibise and tarsi paler, the first five antennal 

 joints pale the others black. Head and prothorax moderately closely and not 

 very coarsely punctate; third joint of antennae about as long as the next two, 

 which latter are equal, sixth joint smaller than fifth, seventh wider than 

 sixth, eighth wider than sixth and rather strongly transverse, last three joints 

 very much wider than the eighth and strongly transverse. Scutellum sparsely 

 and finely punctate. Elytra with regular rows of moderate punctures ; inter- 

 vals irregularly, finely punctate. Beneath not coarsely nor closely punctate. 



Arizona (coll. O. Dietz). 



This looks very much like certain species of Platydcma of the 

 family Tenebrionidse. The genus Scccothcr is closely related to Myco- 

 tctrus from which it principally differs by its short, transverse men- 

 turn and the tibise scarcely dilated at apex. Only one species, ^. car- 

 bonarius Champ., was known so far, which was described from 

 Mexico. vS". opacus seems to be very closely allied to ^. carbonarius 

 but the scutellum in the former is not " thickly punctulate as the rest 

 of the upper surface," and the color of antennae and legs are different. 



Family CHRYSOMELID.F:. 

 Plagiodera versicolor Laich. 



Specimens which agree with the description of this European spe- 

 cies were taken by Messrs. E. Shoemaker, Lewis B. Woodruff and 

 Wm. T. Davis, commonly on willow on September 9, at Bull's Head,
