NEW MALLOPHAGA. I 53 



An immature specimen taken from a Greenwinged 

 Teal, Anas carolinensis (Lawrence, Kansas), is almost 

 as large as the average adult, but is uniformly pale, faintly 

 tinged with clear brownish, showing no markings except 

 a distinct black ocular fleck and the brown mandibles. 

 The dimensions of this specimen are: Body, length 4.5 

 mm., width 1.43 mm.; head, length .81 mm., width 1.28 

 mm. 



Laemobothrium similis n. sp. (Plate xiv, figs, i and 2.) 

 A single specimen from an Eared Grebe, Colyniibus 

 nigricollis calif ornicus (Lawrence, Kansas). This species 

 is very like Piaget's ema?'gi)iat/(iu (Les Pediculines, 1880, 

 p. 585, pi. xlviii, fig. 8), taken from Gall inula hama- 

 toftus (Zool. Garden of Rotterdam), but lacks the occi- 

 pital bands of the head, has more of the peculiar, short, 

 flattened, stiff points on the front margin of the head, has 

 a very differently shaped prothorax (if Piaget's descrip- 

 iion and figure are accurate), lacks the strong markings 

 of emargination, and is a slightly larger species. My 

 specimen is probably not adult, but is of not earlier stage 

 than the last nymphal one. Adult specimens will measure 

 a little larger, and will be a little more strongly marked. 

 This genus has not before been found on a pygopodous 

 bird. 



Female, body, length 4.4 mm., width .87 mm.; uncol- 

 ored (weakly pale brownish) with narrow, sharp, brown 

 markings on head and thorax. 



Head, length 1. mm., width .78 mm.; ocular emargina- 

 tion slight, contraction of sides of head even with the 

 mandibles strong, sides of forehead slightly converging; 

 front with rounding emargination, angles rounding; on 

 each side of the center of the emargination toward the 

 angle are a short hair, a longer hair arising from ventral 

 surface, two short flattened spines, and projecting over
