"It is a large conspicuous species about 3 mm. (^ of an inch) 

 in length, quite broad, the head nearly circular in front and con- 

 stricted behind ; the thorax small the abdomen widening to near the 

 end and terminating abruptly. The head, thorax and legs are 

 yellowish with dark margins and spots ; the abdominal segments 

 bear lateral whitish fascia bordered with black."

The \^ariable Chicken Louse (Lipeuriis variabilis, Nitzsch.) 



The description in op. c. is as follows: "It is about 2 mm. 

 (1-12 of an inch) in length, the body eolngated of a whitish color 

 and smooth and shinmg. The margins of the body are black ; 

 the head is large, rounded on the anterior margins and the whole 

 appearance sufficiently distinct from any of the species infesting 

 chickens, so that there can be no difficulty in distinguishing it at 

 a glance."

The Pigeon Lipeurus (Lcpeiirus bacuhts, Nitzsch). 



Following is the description in the above cited work: "It is 

 about 2 mm. (1-12 of an inch) in length, the body very slender; 

 the head and thorax are of a bright reddish brown color, while 

 the abdomen is rather dusky with a series of patches of a brown 

 color corresponding with the segments of the abdomen. So far 

 as known this species is confined to pigeons and there seems no 

 danger of their being transmitted to other fowls with which they 

 may associate."

A CHICKEN FEATHER MITE. 



Immense numbers of this mite were collected by Mr. G. P. 

 Wilder on the chicken feathers and brought to this office for study. 

 Its identity has not as yet been ascertained but it is doubtless one 

 of the comnion poultry pests.
