80 FIKST ANNUAL KEPORT OF THE STATE ENTOMOLOGIST. 



Mallophaga — (from mallos, wool, a,ndi phago, to eat); containing 

 the bird-lice of the Hemipterous group Mallophaga, having jaws for 

 feeding on the delicate parts of the feathers and hairs of birds and 

 mammals. 



BIBLIOGRAPHY 



A feature introduced for the first time in our State Entomological 

 Reports, and which it is hoped will meet with approbation, is the 

 list of references to publications which will precede each species 

 discussed, giving in addition the synonomy when the species has been 

 known under different names. It is not attempted to make the lists 

 as full as those presented in the popular volumes of Dr. Coues on The 

 Birds of the North-ioest and The Birds of Colorado Valley, and by 

 other recent writers in Natural History, for such elaborate and valu- 

 able compilations can only be the fruit of the systemized study of 

 years with this purpose in view, together with unusual facilities for 

 the work. It is only proposed to cite the author of the species and its 

 first publication ; to give a few references to European authors when 

 such occur and seem to be of value to the entomological student ; to 

 note some of the best figures which have been given ; and to refer to 

 such of the notices occurring in the recent entomological literature 

 as have come under observation, many of which may be accessible 

 to the general reader, in the Reports of our State Entomologists, Ag- 

 ricultural Reports, and leading agricultural journals. 



A bibliography limited to this extent should not be regarded as ob- 

 jectionable by those who have no desire to avail themselves of it ; 

 while the student who would gladly obtain more extended information 

 of the species than that presented, may find it of practical value. 

 Full bibliography, in all departments of Natural Histoi-y, is of great 

 importance in scientific research, and it is much to be regretted that 

 the vast amount of labor which it involves so seldom permits it to be 

 presented. If shared by many, each contributing his mite, the task 

 will be materially lightened and eventually accomplished.
