328 THE CANADIAN ENTOMOLOGIST 



on account of the lack of any heavy markings. It is possibly a 

 suffused variety of puertata, hut the markings above seem tf) 

 indicate a distinct and apparently rare species. 



I take pleasure in naming this form in memory of Mr. John 

 Grossbeck, whom I considered our best authority on the Geo- 

 metridie, and who, shortly before his death, wrote me that he 

 was taking up the mixed Macaria-Sciagrapkia group. I'n- 



fortunately he was never able to finish this work, ha\ing only 

 commenced to assemble the material at the time of his decease. 



Holotype—&, La Puerta Valley, Calif., July 11 (G. Field); 

 also in my collection. 



Allotype— 9, La Puerta Valley. Calif., July 11 (G. Field); 

 in my collection. 



Paratypes — Both sexes, from same localit\', all taken b\- Mr. 

 Field; in his collection and mine. 



Macaria minuta (Hulst). 



Another species, which I was intending to describe. 1 came 

 across labelled by Mr. Grossbeck as Diastictis minuta Hulst. If 

 this identification is correct, as I believe it to be, the species is 

 not a Diastictis, but a Macaria. 



Above, it has a slight resemblance to M. grossbecki: Inii below. 

 the extradiscal shading forms a bright ochre band, which is not 

 solid, and extends only half way to the outer margin. 



I have a very pale female, labelled by Mr. Grossbeck, in 

 error. ''Sciagraphia heliothidata?" Evidently it puzzled him. I 

 think the strong fuscous marginal shading above and the light 

 ochre below will serve to distinguish this obscure species. Hulst 

 was doubtless puzzled through ha\ing only females. There are 

 four brown spots on the costa, from which run pale, irregular, 

 orange, black-shaded lines. 



Macaria puertata Grossbeck is one of the most easily recognized 

 species, and should be readily known by the characters of the 

 underside, as should all these closely-related species. 



My specimens of M. minuta are from La Puerta Valley, Calif., 

 July 11, and Prescott, Ariz., Aug. 13, collected by Messrs. Geo. H. 

 Field and E. J. Oslar
