666 Coleopterological Notices, VII. 



This species is allied to setosus, but differs in its much longer 

 erect bristles, denser and more uniform crust of scales, pattern of 

 ornamentation, and many other less prominent characters. Three 

 specimens. 



SIBIXIA Germ. 



The following species seems to be congeneric with fulva, but is 

 very much smaller and more narrowly oval, and has the scutellum 

 concealed, as in the European primita, which it considerably re- 

 sembles in outline. 



S. oclireosa n. sp. — Oval, strongly convex, dark rufo-piceous in color, 

 the beak and legs pale; integuments densely clothed above with moderately 

 elongate, closely decumbent, uniformly bright ochreous-yellow scales, the 

 scales denser and more prominent by superposition along the median parts of 

 the elytral intervals, but without isolated suberect squamules, the scales of 

 the under surface whitish and much broader, forming a dense crust. Head 

 and basal parts of the beak densely squamulose as usual, the beak distinctly 

 shorter than the head and prothorax in both sexes, differing but little sexually, 

 rapidly tapering, polished and glabrous beyond the antennse, the latter in- 

 serted at the middle in the female and just beyond that point in the male, 

 short and stout in both, the scape relatively shorter and the club smaller in 

 the female. Prothorax about 2}4 times as wide as the head, % to % wider 

 than long, the sides strongly convergent and almost evenly arcuate from base 

 to the feeble apical sinuation; apex rather less than % as wide as the base; 

 punctures concealed, moderate in size and depth and polygonally crowded. 

 Elytra rather short, oval, less than 2% times as long as the prothorax and not 

 more than % wider; sides parallel, distinctly and evenly arcuate, the apex 

 broadly obtuse, the apices individually rounded; humeri obliquely rounded 

 and not exposed at base; strife moderate in width, shallow, with deep and 

 somewhat widely separated punctures, each of which bears a long slender and 

 decumbent hair-like squamule. Legs short and stout, rather densely squamu- 

 lose. Length 1.4-1.6 mm.; width 0.65-0.75 mm. 



Texas (Brownsville). Mr. Wickham. 



Kesembles Tt/c/iiws sibinioides, but with the beak shorter and 

 the scales of the upper surface shorter and denser, without semi- 

 erect squamules along the intervals. 



Zygopini. 



The generic characters of this tribe were only superficially 

 outlined by LeConte in the " Rhj^nchophora of America North 

 of Mexico," and Zygops had not been discovered within our 

 territories at that time. Psomus, allied to Acoptus, has also 

 been added recently. Another statement of the genera occurring.
