Genus CNIPARCHUS Cabanis and Heine. 



(1)Megapicos<' Malherbb, Bull. Soc. Hist. Nat. Moselle, 5e cahier, 1848-1849, 

 17. (Tjrpe, by original designation, M. grayi Malherbe=Pi«M pollens 

 Bonaparte.) 



Oniparchus') Cabanis and Heine, Mus. Hein., iv, heft 2, July 11, 1863, 98. 

 (Type, Pieus hiematogaster Tschudi.) 



Large Picidse (wing about 173-193 mm.) resembling Scapaneus but 

 diflfering in relatively longer and more slender bill, much shorter 

 (rounded and "bushy" instead of pointed) crest, shorter and more 

 rounded wing (longest primaries exceeding secondaries by less than 

 one-fifth the length of wing), with relatively larger and broader tenth 

 primary, relatively longer tarsus, and banded inner webs of remiges. 



Bill longer than head, rather slender, regularly wedge-shaped in 

 vertical profile, decidedly broader than deep at anterior end of nos- 

 trils; culmen staight for most of its length but very faintly convex 

 toward base, sharply ridged; gonys a httle more than twice as long 

 as mandibular rami, distinctly ridged, straight for greater part but 

 slightly convex basally; supranasal ridge very distinct, running out 

 to edge of maxilla at a Httle less than one-third the distance from tip 

 to base of tomium. Nostril large, longitudinally elhptical-oval, 

 much nearer to tomium than to culmen, at least partially covered 

 by small antrorse prefrontal feathers. Malar apex and chin with 

 feathers not distinctly antrorse. Orbital region extensively and com- 

 pletely naked. Wing rather short, much rounded, the longest pri- 

 maries exceeding secondaries by less than one-fifth the length of 

 wing; fifth, sixth, and seventh primaries longest, ninth shorter than 

 fourth, tenth (outermost) nearly two-thirds as long as ninth, strongly 

 bowed or incurved, very broad (greatest width equal to one-sixth or 

 more the length). Tail nearly two-thirds as long as wing. Tarsus 

 much longer than outer hind toe without claw. " 



Coloration. — Inner webs of remiges blackish broadly banded or 

 transversely spotted with white or buffy; rump red or huffy; a white 

 or buffy stripe from nostrils across lores and beneath orbital and 

 auricular regions to side of neck; pileum red; rest of plumage black, 

 the under parts of body dark red in O. hsematogaster and C. h. splen- 

 dens, barred with black and tawny in 0. pollens; bill black. (C. 

 hsematogaster and its subspecies have the rump red, and no white on 

 back; C. pollens has the lower back and rump pale buff, lower rump 



« The interrogation mark here has reference to the question of whether Picas pollens 

 and P. hsematogaster are really congeneric. (See remarks under footnote c.) 

 6 "Von Kvl^, Holzwurm und Upxt^: herrschen." (Cabanis and Heine.) 

 c The generic description (except as to color characters) is taken entirely from the 

 type of the genus C. hsematogaster (Tschudi), the only skin available at tie present 

 time of C. pollens (Bonaparte), a species which is doubtfully congeneric but which 

 agrees fairly well in structural and color characters, being so yoimg that I cannot 

 be sure as to relative proportions of the bill, etc.
