formed by the deep emargination of the posterior border; two long 

 hairs arise from the angle just behind the frontal constriction; two 

 black blotches on the front margin, a black fleck bordering the con- 

 striction inwardly, a large black blotch just behind constriction ex- 

 tending to center of lateral border and is continued fainter backward 

 and inward, a narrow, curving, underlying bar extends backward 

 and inward from a point before the anterior lateral flecks: a pair of 

 black anterior metathoracic blotches show plainly through the hyaline 

 posterior-lateral lobes, and from the inner points of these, fainter bars 

 run inward and backward, finally paralleling the median Ime: six long 

 hairs occur along the anterior portions of the lateral margins and 

 four shorter ones from the posterior lobes; a peculiar H-shaped plate 

 involves the entire segment through the cross-bar of which a faint 

 clear stripe intersects. Metathorax and mesothorax, which are indis- 

 tinguishably fused, are continuous with the abdomen; two short 

 spines at each anterior angle, twelve long hairs along the margin of 

 the segment and a central transverse series of six shortish hairs; 

 margined laterally by a dark brown border which widens greatly pos- 

 teriorly; a narrow band parallels this just mediad of same; another 

 narrow band arises inwardly on each side which runs backward and 

 inward, and meets transversely on the first abdominal segment; from 

 the hindmost end of the lateral border horn-like bars are projected 

 backward onto the first and second abdominal segments. Legs con- 

 colorous with ground color and thorax, with dark marginal borders. 

 Abdomen narrowly elliptical, with no marginal constrictions be- 

 tween segments; each segment with three or four long hairs and 

 three or four short hairs laterally; segments one to eight, inclusive, 

 with a transverse row of long spines at the posterior margin as fol- 

 lows : Segment one, 14: segment two, 14; segment three, 16; seg- 

 ment four, 16; segment five, 10; segment six, 14; segment seven, 9; 

 segment eight, 6; first and eighth segments the shortest: terminal 

 segment with a marginal fringe of about 20 hairs: segment one with 

 a median, triangular, brownish blotch whose apex invades the meta- 

 thorax; remaining segments (excepting the last) each with a trans- 

 verse band of same color, which are shallowly emarginate laterally, 

 thus leaving a clear region inside the brown lateral bands which are 

 lined within with a parallel, semi-hyaline edge. 



Physostomum melospizae n. sp. (PI. XXVIII, figs. 3, G.) 



Two females (McGregor No. 90, or No. 178 of the Wash- 

 burn Minnesota collection from the song sparrow, Melospisa 

 melodia, St. Anthony Park, Minnesota. Possibly nearest P. 

 sncinaceiim Kell. from the western flycatcher ; not at all like 

 the Physostomum of the golden-crowned sparrow. 

 Type No, 21608, United States National Musevim.
