The specimens were mounted on 75 x 25 mm. slides and covered with 

 round, 12 mm. cover slips. After drying for several days on a 40°C. 

 slide warmer they were ringed with asphaltum. Specimens were mounted 

 separately or, when possible, a d' and 9 of the same species were mounted 

 on the same slide. 



Measurements of total length and width and length of the abdomen 

 are unreliable in many of the Menoponidae as they are dependent on the 

 amount of pressure exerted by the cover slip in mounting which often 

 causes "telescoping" of the abdomen. The length of the head is again 

 an unreliable measurement owing to the fact that the head often does 

 not lie flat under the cover slip and the occipital margin may be dis- 

 torted. The measurements least affected by distortion seem to be those 

 of the width of the head at the temples and at the preocular enlargement 

 and probably also the width of the prothorax. Nevertheless, I believe 

 that measurements are still an important character in that they give an 

 indication of general size which can be used for comparative purposes. 



In New England, there are commonly found seventeen of the nine- 

 teen orders of birds found in North America north of Mexico. The orders 

 not found here are the Psittacif ormes and the Trogoniformes. The petrels, 

 can be found in the waters off the New England shores but due to a paucity 

 of both collections of these birds and their Mallophaga, a study of this 

 order was impossible. 



The New Hampshire Fish and Game Department (1964) lists 296 

 species of birds occurring in the State of New Hampshire, 74 of which 

 are considered rare or very irregular, leaving 222 more or less common 

 species. The Checklist of Birds of Southern New Hampshire (distrib- 

 uted by The University of New Hampshire Bookstore) lists 214 species 

 (215 including the Starling which was inadvertently omitted) . 

 Dearborn (1903), in his Birds of Durham and Vicinity lists 252 species, 

 and the Audubon Daily Field Card published by A. W. Argue, Boston, 

 Massachusetts, lists 282 species of birds which may be found in the 

 New England area. 



The host classification followed is that of the A. 0. U. Checklist 

 of North American Birds, fifth edition. Sub-species are omitted. Rare 

 and accidental species are omitted except where noted. Exotic species 

 successfully introduced are included. 



During the course of this study, the Mallophaga collections of the 

 United States National Museum, University of Rhode Island, University of 

 Massachusetts, Harvard University and the Connecticut Agricultural 

 Experiment Station were examined. 



The New England records of Mallophaga from the Cornell University 

 collection were also used.
