yellow and the terminal segment of the antennae sanguineous. The 

 first segment of the antennae is a trifle longer than the second. 



Mamurius mopsus Stal. 



Four specimens of this species were taken in the Huachuca Mts., 

 Arizona. 



Burtinus notatipennis Stal. 



A single specimen was obtained in the Huachuca Mts., Arizona. 

 After a very careful comparison of this specimen with Stal's descrip- 

 tion of notatipennis and Distant's femoralis I am fairly certain that 

 the latter is a synonym of Stal's species. Stal, evidently through 

 oversight, neglected to mention the series of ventral black spots on 

 the abdomen, the four pronounced long, black spines of the posterior 

 femora which are mentioned by Distant in his description. The 

 single specimen before me has only a slight indication of a pale spot 

 behind the middle of the corium and lacks the darker coloring beneath 

 the head but in this is probably subject to variation. In all other 

 respects this specimen agrees with the two descriptions. This species 

 has dorsally a very close resemblance to Megalotomiis quinque-spi- 

 nosus Say. 



Harmostes subrufus Dist. 



I collected eight specimens of this species in the Huachuca Mts., 

 Arizona. The basal segment of the antennae extends about one third 

 of its length beyond the apex of the head and the enlarged fourth 

 joint is a trifle longer than the basal joint; the humeri are broadly 

 rounded; the areas between the veins punctate and mottled with red- 

 dish brown ; narrow reflexed costal margin of corium immaculate. 

 Xenogenus extensum Dist. 



Two specimens collected in the Huachuca Mts., Arizona. They 

 have the appearance of a long, narrow Harmostes refleculus Say. 

 The fourth segment of the antennae is not much thickened and only 

 slightly shorter than the third segment; the antenniferous tubercles 

 are not produced nor spined; the ocelli are elevated; the anterior 

 angle of the pronotum is not produced in a spine; the apical half of 

 the posterior femora armed with some twenty-five sharp spines. 

 Stenomacra marginella H. Schf. 



This species was very common in a garden in the Huachuca Mts., 

 Arizona, where I found it feeding on Asparagus. The fore tibiae
