writer are carefully considered, and their affinities pointed out so far as 

 practicable from the descriptions. In these notes the authors describe and 

 name a new genus Rileya (type R. americana), in honor of Dr. Riley. 

 It is unfortunate that two Hymenopterous genera have already been, 

 named Rileya, one by Mr. Howard and one by Mr. Ashmead. The 

 tachinid genus might, however, be known as Rileymyia. Further notes 

 on the sections and the genera they embrace follow, together with a sum- 

 mary of the writer's groups and genera of North American Tachinidse 

 s. sir. given in the Trans. Am. Ent. Soc. A supplement to the alphabetic 

 list of species mentioned in the work comes next. The whole is con- 

 cluded by a general index of all the genera mentioned in the three parts, 

 which contains all the Calyptrate Muscid genera of the world erected up 

 to the time of publication of this part.— C. H. Tyler Townsend.
