DISSOSTEIRA Scudder. 

 Dissosteira Carolina (Linnaeus). 



Two females of this species were taken on cultivated ground at 

 Albuquerque, September 14. 



SPHARAGEMON Scudder. 

 Spharagemon collare (Scudder). 



A pair of this species taken at Albuquerque, September 14, on irri- 

 gated land are in the collection. They are closer to race angustipennis 

 than to the other forms of the species. 



In this location this species was extremely difficult to capture, par- 

 tially on account of its powerful flight and its extreme wariness. This 

 is the only locality in New Mexico from which the species has been 

 recorded. 



T0M0N0TUS Saussure. 

 Tomonotus aztecus Saussure. 



Apparently this species is generally distributed over that portion 

 of western Texa? between San Antonio and the Pecos River, specimens 

 before us being from Lacoste, Medina County (1 c?), Hondo, Medina 

 County (1 9 ), D'Hanis, Medina County (2 6", 2 9 ), Sabinal, Uvalde 

 County (1(5*), Spofford, Kinney County (2 cf), and Samuels, Valverde 

 County (2 9 ), all taken during train stops on July 8. 



The Samuels specimens are quite pale, while two of the D'Hanis 

 series are quite uniform blackish-gray. The Sabinal, Spofford and 

 Hondo individuals are as a rule quite dark, the Sabinal and Hondo 

 representatives with the tegminal markings distinct, while the Lacoste 

 specimen tends toward ferruginous. 



The senior author's Lactista boscanus u from Ysleta, El Paso County, 

 Texas, is referable to this species. As shown by Caudell 15 the speci- 

 mens recorded by Scudder and Cockerell as Lactista pellepidus also 

 belong to this form. 



The range of this species in the United States is now known to 

 extend from central Texas to south-central Arizona, north to the 

 Organ Mountains of New Mexico. 



MESTOBREGMA Scudder. 

 Mestobregma fusoifrons (Stal). 



Five males and one female of this form were taken at Spofford, Texas, 

 July 8 ; one male and two females also being taken at Dunlay, Medina 

 County, Texas, the same date.
