rather small specimen of the latter species; the narrow constricted 

 reniform and the even brown color of both types point to this asso- 

 ciation ; sobrialis Wlk. has a rather broader, shorter reniform and less 

 even coloration. Smith has figured the type of restrictalis in his revi- 

 sion of the Deltoids (PI. 7, Fig. 1) but the details of maculation do 

 not show well ; we figure a $ agreeing with the type. 



Renia centralis Grt. 



The type at Philadelphia is the $ of the same species as that 

 described later by Grote from the 5 sex as plenilinealis. Both names 

 (and presumably also alutalis Grt., the type of which we could not 

 find at Philadelphia) fall before factiosalis Wlk. 



A type of centralis in the British Museum is very worn and pos- 

 sibly not the same species as the $ type in Philadelphia which is a 

 good specimen and easily recognized ; we would restrict the type 

 therefore to this specimen at Philadelphia. Smith has given fairly 

 recognizable figures of the species on PI. VI of his Deltoid revision; 

 we cannot separate tilosalis Sm. described in Jour. N. Y. Ent. Soc. 

 XVII, 70, 1909, and of which we possess cotypes, from factiosalis.

Racheospila obliqua Hist. 



We think the species should be transferred to the above genus 

 rather than be left in Nemoria as the palpi in the 2 are decidedly 

 long; Mr. Prout to whom we suggested the change, concurred with 

 the suggestion, stating that obliqua was unknown to him at the time 

 of the revision in the Gen. Insectorum. We are not sure but that 

 obliqua and bellonaria may represent seasonal forms ; the type $ of 

 obliqua in the Hulst Coll. is rather small and without discal dots, 

 whereas bellonaria has distinct discal dots and is larger; all the Colo- 

 rado material before us of the former type is dated August, whereas 

 the specimens of the latter form were captured in May and June which 

 would point to either a double brood or a distinct species. More ma- 

 terial than we possess will be necessary to decide the question. 



R. LOUISA Hist. 



The $ type in the Hulst Collection is not the same species as the 

 $ type in the National Museum, being a specimen of hulstiana Dyar ; 

 this would account for Hulst's misidentification mentioned by Dr.
