up-to-date genera. He says, " // is easy to stigmatize ivhat one 

 will not take the trouble to understand." I have very carefully 

 studied these up-to-date genera and also those proposed in the 

 last thirty years and that is the reason I have not adopted 

 them. If anyone familiar with the Hesperidae will consult Dr. 

 Dyar's review of the family * he will find generic fantasies 

 to satiation, and will also see that in many cases the species 

 in a given genus are more nearly related to species in other 

 genera than they are to each other. Several examples of 

 generic fantasies will suffice. The species nianataaqua Scud- 

 der and cernes Bdl.-Lec. are so close that it is not unlikely 

 that they are forms of one species, yet the former is placed 

 in the genus Limochroes and the latter in Thymelicus, and 

 these two genera are separated in his review by SEVEN- 

 TEEN other genera. Associated with manataaqua are a rpa, 

 palatka and dion which are not closely related to it. The pin- 

 nacle of fantasy is illustrated by the following : Thirty-four 

 years ago Mr. Scudder proposed the genus A try tone without 

 description, and cited as the type iowa Scudder (arogos Bd. 

 Lee). Dr. Dyar in his review erects the genus Anatrytonc 

 and places the type of Atrytone among the four species in his 

 new genus and considers them congeneric. The species he 

 places under Atrytone are not congeneric with the type. The 

 so-called up-to-date genera are replete with this sort of thing, 

 but space forbids dilating on it further. Dr. Dyar is sure of 

 one man who won't swallow up-to-date genera on the imputa- 

 tion that he has never studied them.

[Those interested in the entomolog)' of the United States, 

 especially of their southern portions, will inevitably have their 

 attention attracted more and more to the insect-fauna of 

 Mexico and Central America. As entomological exploration 

 of the region to the north of the Rio Grande and the Gila pro- 

 gresses, the greater will be the number of species found to be 

 common to the United States and to Mexico. Although every
