THE CANADIAN ENTOMOLOGIST. HI 



Marginal lines black, present on all wings. Fringes paler than above 

 Thorax, abdomen and legs ashen, with dark scales sprinkled heavily on 

 femora and fore legs, and on abdomen toward tip. 



The type, a female, has long been a unique in the collection of Mr. 

 W. H. Broadwell, who has kindly allowed me to retain it, and bears the 

 label, Palmerlee, Arizona. The single male co-type is from the collection 

 of Dr. Barnes, submitted to me by Mr. J. A. Grossbeck, and was taken at 

 Redington, Arizona, January i, 1910.

ON MERRAGATA LACUNIFERA BERG. 



BY J. R. DE LA TORRE BUENO, WHITE PLAINS, NEW YORK. 



In 1879, i" h's ''Heniiptera Argenti?ia,"^ Carlos Berg described a new 

 Lygaeid genus, Lipogomphus^ placing it near geocoris^ which contained a 

 ne\v species, lacuniferus^ so called because of the white corial lacuna 

 bounded by the thickened brown veins. This was founded on three 

 specimens of an unknown bug taken in Buenos Aires by himself, in com- 

 pany with the Argentine Entomologist, Enrique Lynch. Subsequent 

 study caused him in 1884;^ to phce his new genus near Hebrus Curtis 

 (now sometimes Nœogeus Laporte). No further reference appears to have 

 been made to this species, except its enumeration by Lethierry and 

 Sévérin,* till 1898, when Champion^ referred the genus to Merragata 

 Buchanan White, whose type, Merragata hebroides F. B. White, is from 

 Mexico. 



To my good friend, Rev. Longinos Navas, the learned Spanish Jesuit, 

 I owe the possession of four examples of this very interesting form, which 

 were secured at Montevideo, Uruguay — a second locality for the sjiecies. 

 These specimens agree very well with the original description, although, 

 being carded and slightly mutilated, the discrepancy in the number of 

 joints in the hind tarsi, which Chalnpion points out, could not be deter- 

 mined without further mutilating them. The number and proportion of 

 the rostal joints in the individuals before me does not agree with the
