Hesperia syrichtus and montivagus (Lep.). 

 By HKXKY SKIXNKK. 



Dr. J. I,, keverdin has published an interesting article* on 

 Ilcspcria syrichtus Kal>. Ik- gives tin- synonymy of the specie- 

 and has made an extrusive study of (lie genitalia from num- 

 erous specimens. As this is a North American species, it is 

 of interest to our students of the butterflies. He describes and 

 figures the typical form and also two new varieties, fitmosa 

 and syrichtides. Fitmosa is the common form at l\'/y West. 

 Florida. The whole underside of the secondaries is light brown. 



It has been a matter of considerable interest to know what 

 the Pyrgns montivagus of Reakirt is. 1 have previously 

 pointed outt that montivagus Reak. is a synonym of svrichtns 

 Fab. The evidence that this is so is very good, but it is hard- 

 ly possible to know these things absolutely. Montirac/us has 

 been treated in different ways by a number of authors. The 

 original description says: "Hab. Rocky Mountains, Colorado 

 Territory. (Coll. Tryon Reakirt)." "Mexico, near Yera 

 Cruz." "Win. H. Fdwards." "Most probably an Alpine 

 modification of the common Pyrgns oilcns." P\r<;ns oilcus 

 West. -Humph, pi. 38, fig. 14-15, is said by the aiuhors to be 

 a North American insect and the figures probably represent 

 syriclitus Fab., where it is placed by Kirby in his catalogue. 

 The Tryon Reakirt collection was purchased bv Herman 

 Strecker and it is now in the Field Museum, Chicago, Illinois.

Mr. \Y. J. Gerhard, of the Field Museum, has supplied me 

 with information in regard to these tvpes. 



"There are in his collection (Streckcr) two specimens, a male and 

 a female, with a red-bordered pin label on each and with the inscrip-

 The male, which is spread to show the under side, is of average size, 

 and. with one exception, agrees exactly with tin- specimen you sent as 

 syriclitus. The exception is that the color of the secondaries Ix-low
