The gall, about 4.5 mm. long, consists of the subglobular swollen 

 base of the Atriplex leaf, the sides being folded upwards, leaving an 

 open slit above, the margins of which are curled outward. The end 

 of the leaf makes a pointed process at the end of each gall. 



Las Cruces, N. Mex. (Townsend and Cockerell) ; Trinidad, 

 Colo. (L. C. Bragg). Trinidad is the type locality. 



Mr. Bragg also reports that he found Kermes gillettei at 

 Trinidad. 



PARASITE. 



A very interesting parasite has been reared from this insect, 

 which seems to possess characters common to the Encyrtinas 

 and Aphelininse. The material is not in condition for descrip- 

 tion, but this statement is made in the hope that some future 

 observer, finding Atriplicia, will try to rear a good series of 

 the parasite. 



THREE NEW TICKS FROM THE UNITED STATES. 



BY NATHAN BANKS. 



In describing Dertnacentor venustus in my Revision of the 

 Ixodoidea, or Ticks, of the United States, a I had a few speci- 

 mens that would hardly fit and were left unnamed, or placed 

 doubtfully with that species. Several males, in the collection 

 of the Department of Agriculture, were from Prescott, Wash- 

 ington, taken from a horse in February, 1896. Since the pub- 

 lication of the Revision I have received several ticks from Dr. 

 H. T. Ricketts, who is interested in the spotted fever, and 

 among the material were two females and a male from a horse 

 at Mountain Home, Idaho. These agree with the specimens 

 from horse at Prescott and differ from D. venustus in several 

 ways, so that I shall describe it as follows : 



Dermacentor modestus, n. sp. 



Male. Red-brown, marked with white lines and dots, but not so 

 heavily as in D. venustus or D. occidentalis; the heaviest marking out- 

 lines the region of the shield of the female; legs slightly marked with 

 white. Capitulum scarcely as broad as that of D. venustus, the hind 

 angles hardly as much produced; dorsum hardly as much widened 

 behind as that of D. venustus, punctulate as in the allied forms; hind 

 coxae about twice as wide as long on base, armed as usual. 



Length, male, 3.5 mm.

 of Agriculture, 1908.
