the lateral angles; a hiovvnish marginal band fading posteriorly runs backward from 

 the lateral angles; narrow, black, ventral bands (showing through from beneath) 

 running from the lateral angles to the anterior angles, and from there backward to the 

 posterior portion of the median, longitudinal band ; coxk visible from above. Meta- 

 thorax large, with sides straight and diverging, posterior angles with one long and 

 two short hairs; posterior margin rounded, with four long hairs ; a circular brown 

 blotch at the median portion of the anterior margin, ])r()jecting over into the prothorax ; 

 another larger, somewhat quadrangular lilotch in the posterior median jwrtion of the 

 segment ; the two posterior pairs of coxk showing through very distinctly as black 

 circular lines ; narrow black bands on the ventral surface as follows : one long 

 curving band from the anterior angles to the middle of the first abdominal segment ; 

 one along the anterior border from the angles inward to the border of the median 

 circular blotch, then straight backward to the middle of the segment; lastly a trans- 

 verse, intercoxal band from the middle of the curving lateral bands inward to the tip 

 of the longitudinal band and then curving backward to the margin of the segmertt. 



Abdomen oval, with posterior angles slightly projecting and furnished with one 

 long and one short hair on segments one to four and six and seven ; two short ones 

 on segment five, two long and one short one on segments eight, and two long ones in 

 the middle of the eighth segment, which has the appearance of being divided trans- 

 versely ; posterior margins of the segments slightly curving anteriorly, with a fringe 

 of short, unpustulated hairs; lateral bands of segments dark brown, broad and slightly 

 broken at the sutures; heavy, median, transverse bands, nearly reaching the lateral 

 bands, and broken by clear sutures, except between the eighth and ninth segments ; 

 ninth segment large, longer than the others, with rounded posterior margin and 

 darkened tip ; genital hooks laige and heavy, extending from the fifth segment to the 

 ti[) of the abdomen. 



Legs long and stout ; femora swollen, especially the anterior pair, with several 

 short hairs along the anterior margin ; all with darkened base and tip and with a large 

 clear pustule near the base (not shown in the plate on the two posterior pairs) ; tibiae 

 slightly swollen, and darkened at the tip, where there is also a clear pustule ; a fringe 

 of short hairs near the tip on the inner side ; tarsi with the first segment short, the 

 second long and stout ; ground color of legs the same as body, a very pale testaceous. 



A single male collected from an American Crossbill {Loxia curvi- 

 rostra minor) at Warbonnet Cafion, Sioux Co., Neb., June 17, 1901. 

 This is the first record of any species of Colpflcephalum being col- 

 lected from this host and the species is quite distinct, though it has a 

 somewhat superficial resemblance to the general color and outline of 

 laficeps Kell., but it is very readily recognized by the bold blackish 

 bands on the ventral surface of the thorax, which show nearly as plainly 

 from above as below. 



Physostomum picturatus, sp. nov. (PL XXIII, Fig. 3.) 



Ft-jualt-. — Body, length 2.9 mm., width .65 mm. ; almost white, except a tint of 

 golden on the prothorax and a few dusky median spots on the abdomen ; with heavy 

 blackish borders to the abdomen and thorax.
