MALLOPHAGAN RECORDS AND DESCRIPTIONS. 



Herbert Osborn. 



III. LOUSE OF THE RUSTY GRACKLE. 



Docophonis barbatus ii. sp. 



Elongate, head and thorax red brown, abdomen fuscous brown. Length 

 2 mm. 



Head much narrowed in front of antennae, the margin shghlly incurved ; 

 clypeus convex in front, clypeal signature long, narrow behind, clypeal space 

 bordered by sinuate chitinous bars ; trabecule conic, anterior border scarcely 

 .sinuate ; antenna? small, fir.st joint thick and short, second longest. Border 

 of head with five bristles in front of antennae, two long bristles and two 

 short minute hairs on border behind antennse, and four very minute hairs on 

 occipital border. Prothorax quadrate, anterior angles rounded, postero- 

 lateral angles nearly rectangular, hind border slightly convex, a long bristle 

 in angle ; metathorax with prominent lateral angle and with three or four 

 -strong bristles. Abdomen elongate ovate, scarcely wider than head ; fascia 

 broad, fuscous brown, each segment with marginal row of strong bristles ; 

 terminal segment with distinct incision. 



The male genitalia are slender, the terminal segment almost truncate with 

 a few stiff bristles on apical margin, the segment being dark below and the 

 abdominal fasciae nearly continuous above. 



This .species presents some quite remarkable similarities to 

 .speot3'ti 0.sb., especially in the clypeal strticture and the excision 

 of terminal segment in the female, and ^vere there not apparent 

 certain constant differences I shoitld be tempted to think it that 

 species and its occtirrence on the grackle accidental. The shape 

 of head, terminal segment of male and genitalia differ, and I 

 conclude they must be distinct. Collected from the rusty grackle, 

 Scolecophagus carolinus, at Lincoln, Nebraska, by Professor 

 Lawrence Bruner. 



IV. NEW SPECIES AND RECORDS IN COLPOCEPHAEUIM AND 



PHVSOSTOMUM. 



Colpocephaluiii pectinatum n. sp. 



Light brown with conspicuous ocidar and occipital spots. Length 2 mm. 



Head of usual form ; anterior border strongly convex ; about six minute 

 hairs and one long bristle in front of the antennae ; postero-lateral lobes with 

 three long bristles and several small hairs. Occipital spots connected b}- a 

 brown band, but no distinct connecting band with the ocular spots. Pro- 

 thorax with prominent lateral angles, a strong bristle and a small hair at 

 extreme angle and six bristles on the hind border. Metathorax with long 

 marginal bristles. Legs unicolorous, the hind femora with three combs of 

 minute teeth. Abdomen elongate ovate, with faint brownish transverse 

 bands and a row of marginal bristles ; third segment below with two combs 

 cf minute hair-like teeth on each side, a little nearer the margin than median
