hi'ail nnd thorax. In the cut the outer short carina of thorax is ac- 

 cidentally omitted. 



One specimen collected by myself at Camp Grant, Arizona. In the 

 accompanying cut, fig. 1, is G. brcvicristatitm, and fig. 2, G. coHtufr. 



P.^cu(lopsis sulcatus, Nm. Specimens of this species have been 

 taken rather abundantly near Grimsby, Ontario, by Mr. Johnson 

 Pettit. On comparison of these with a type from England I find no 

 specific diftcronces. 



SAPRINUS, Er. 

 S. seneipunctatus, n. sp. — Black ojKniue. Form short robust. Head rctrae- 

 toil, front with few punctures, transverse ridge faint. Thorax twice as broad as 

 long, sides feebly rounded and gradually narrowed anteriorly; surface densely 

 punctured at the sides, smoother and less densely punctured at middle. Ely- 

 tra very densely and coarsely punctured over the entire surface, humeri with 

 small smooth s])aee; jiunctures brilliantly oeneous at bottom. Strioe almost en- 

 tirely obliterated, the first dorsal long, second, third and fourth very short, thi' 

 latter united by faint arch with the nearly obsolete sutural ; humeral stria 

 nearly obsolete, one subhumeral moderately distinct. Anterior tibire five-den - 

 late, the lower three teeth strong; hind tibias triseriately strongly sninulose. 

 Prosternurn acutely carinate. Body beneath black shining, coarsely punctured 

 at the sides, smoother at middle. Pygidium convex, densely punctured and 

 nearly vertical. Femora smooth. Length .12 inch ; breadth .10 inch; .3 — 2.;> 

 mm. 



This species must be referred to ^larseul's group V, and Leconte'.'* 

 gvornp 9 near pafraclis and liicidiilns. It resembles in form a minia- 

 ture sulcifrons^ and is more coarsely and densely punctured than any 

 .species in our fauna. Resembles also hi(jem7neits, Jjcc, but may be 

 readily known by the compresso-carinate prostcrnum and the absence 

 of the well defined small scutellar spaces of that species, although some 

 specimens of seticipunctatiis, have scutellar spaces slightly more convex 

 than the rest of the surface and somewhat smoother, although punc- 

 tured and rugose. 



Several specimens presented by 3Ir. James Behrens; from the sea 

 coast near San Francisco. 



OTHNIUS, Lcc. 



The above genus was founded by Leconte and indicated as a distinct 

 family. Class. Col. N. xV. p. lOi, at the same time briefly describing 

 one species and indicating a second from memory. Since then two 

 others have been described in our fauna, as follows : 



0. fasciatus, Bland. Proc. Ent. Soc. 1864, 25.'?. Virginia. 



0. lugubris, Horn, Trans. Ent. Soc. ]8t)8, l.!2. Oregon and also 



0. mexicanus, Horn, loc. oil. l.'i.'i, from Mexico. 



Previously however Mr. Pascoe. described a genus under the name 



TUAXs. AMi:n. KNT. SOC. (43) Dr.cKsiuEit, 1871.
