SOME MEXICAN HEMIPTERA-HETEROPTERA NEW 

 TO THE FAUNA OF THE UNITED STATES. 



By H. G. Barber, 



RosELLE Park, N. J. 



In the last few years I have obtained a number of Hemiptera, 

 hitherto recorded only from Mexico or Central America, which have 

 been taken in the extreme southern limits of New Mexico and Ari- 

 zona. The addition of these to our fauna goes to swell the ever- 

 increasing number of insects which are spreading northward from 

 Mexico into the southern limits of the United States where the con- 

 ditions are similar on either side of the border. The majority of the 

 species which I desire here to record are a result of my collecting in 

 the Huachuca Mountains, Arizona, in the summer of 1905. 



Brochymena haedula Stal. 



I took six specimens of this species in the Huachuca Mts., Ari- 

 zona. It is very closely related to B. arborea Say. I have some 

 doubt concerning their separation as distinct species. Stal in his 

 diagnosis in Enum. Hem., 2, p. 17, points out that hccdiila differs 

 in having the three lobes of head equal, the fore tibiae expanded 

 near their apices and the base of all antennal joints paler. The 

 specimens before me have the pronounced dilatation of the anterior 

 tibiae, and with the exception of the possibly more pronounced arma- 

 ture of spines on the pronotal angle I can find no other constant 

 differential character. In these specimens the base of the fifth anten- 

 nal joint is not pale. 



Euschistus spurculus Stal. 



I have received a single specimen from the F. H. Snow Collec- 

 tion from San Bernardino Ranch, Cochise Co., Arizona, collected at 

 an elevation of 3,750 ft. It agrees in every particular with Stal's 

 description but is considerably paler than other specimens which I 

 have from Durango, Mexico. Its occurrence within the United 

 States was noted by Snow in the Trans. Kas. Acad. Sci., Vol. XX, 

 Part I, 1906.
