 — Only he who has endeavored to find his way in the devious labyrinth of 

 the calyptrate Muscidae can appreciate this important and valuable paper, 

 the most important that has ever appeared on the subject, and one that 

 will mark a new epoch in our knowledge of the group. To give even an 

 outline of its contents is impracticable here, nor would I feel at all com- 

 petent for the task, were my opportunities unlimited. A paper that intro- 

 duces fifty new families and one hundred and fifty new genera would 

 appall any ordinary critic, and I know only enough about the insects to 

 appreciate the labor and research the paper has cost. The authors, fol- 

 lowing out Prof Brauer's previously published taxonomic views, present 

 an almost entirely new classification of the group, which is coextensive 

 Vith what has been generally known as the Muscidae calyptratae, with the 

 inclusion of the Oestridse. " Families," groups and genera are defined, 

 and three hundred and ten admirable lithograph figures, graphically illus- 

 trate most of the genera. All the known genera are not included; only 

 those of which the authors had definite or artoptic knowledge; still, there 

 cannot be many wanting, and the work must remain as the sifte qua non 

 of all dipterologists who have anything to do with these flies. The work 

 is nothing if not iconoclastic, and I do not think will, and ought not to, 

 obtain the concurrence of entomologists in all respects. The autliors' 

 conception of the genus is, I think, not tenable, and there is a great lack 

 of uniformity in the group names. But, whatever the differences may be, 

 all will unite in their appreciation of the great value of this bahubrechend 



work. — S. W. WiLLISTON.
