1G2 THE CANADIAN ENTOMOLOGIST. 



As compared with our other species, it is decidedly smoother than 

 any, and less elongate than all except possibly puncticollis, the form of 

 which I do not now recall. In bicolor and gibbula, the only other species 

 now before me, there are three or four elongate spiniform bristles on either 

 side of the prosternum in front, in place of the single Jong and one or two 

 shorter ones in the present species ; perhaps an individual variation. 



Scyrhnus bifugus, n. sp. — Broadly oval, outline nearly continuous, 

 black; head, anterior part of the side margins of the prothorax and two 

 large transverse connected spots on each elytron, yellow ; under surface 

 brownish, legs entirely pale. Upper surface very finely punctulate and 

 moderately shining ; prosternum without elevated lines, sides of 

 mesosternum and abdomen sparsely but more distinctly punctate than the 

 elytra; metacoxal line incomplete, parallel with the first ventral suture; 

 abdomen with six segments. 



Length, 1.5 mm. One example, San Jose del Cabo. Type in the 

 collection of the California Acadamy of Sciences. 



Belongs to Horn's Group I!, and must be associated with amabilis 

 and guttulatus, from both of which it differs by its more broadly oval form 

 and the elytral markings. The elytral spots are nearly equal in size, and 

 are rather narrowly connected at the middle. 



Bostrichus fascicu/atus, n. sp. — Blackish-brown, moderately shining. 

 Head closely punctate, front feebly margined at sides. Prothorax as wide 

 as long, front margin sinuate, with two slender unciform processes ; hind 

 angles prominent, dentiform ; entire upper surface strongly though not 

 very densely tuberculate, and clothed thinly with moderately long, recum- 

 bent, subinterlacing yellowish-brown hairs, with numerous erect pointed 

 tufts of blackish hairs. Elytra coarsely, deeply, subcribrately punctate, 

 without costae ; vestiture similar to that of the prothorax, the interspersed 

 pointed tufts of blackish hairs longer and very conspicuous. 



Length, 7 mm. ; width, 2.4 mm. Santa Rosa, Lower California 

 (Beyer). A most singular insect, totally different in its vestiture from any 

 species previously known to us. 



The elytral fascicular are approximately as follows : a subsutural series 

 of three prominent tufts, exterior to which are three or four others less 

 regularly placed ; a sutural series of much smaller tufts, and a number of 

 similar ones toward the side margin. 



Atanius confertus, n. sp. — Oblong, moderately robust and convex, 

 piceous-brown, surface dull ; beneath red-brown, legs not paler. Head
