NEW COCCID^E FROM THE ARGENTINE REPUBLIC AND 



PARAGUAY. 



BY T. D. A. COCKERELL, E. LAS VEGAS, N. M. 



The Coccidae herein described were collected by Professor L. Bruner 

 in 1897 and 1S98. I examined the collection with more than ordinary 

 interest, as practically nothing was known of the Coccidaa of the Argentine 

 or Paraguay. The flora of the southern part of South America resembles 

 in many respects that of the arid region of North America, and it was 

 therefore not wholly unexpected that this resemblance should extend to 

 the Coccidas. The collection is too small to show how far such a 

 resemblance may extend, but the species of Orthezia and Lichtensia, at 

 least, are entirely representative of North American types. 



(1.) Orthezia ultima, n. sp. — $ . Waxy lamellae in two dorsal series, 

 with a deep median sulcus, and the usual lateral series ; the dark surface 

 of the back is narrowly exposed between the dorsal and lateral series ; 

 anterior lamellae of the dorsal series thick, prolonged over the head, but 

 not greatly produced nor divergent ; posterior lateral lamella? narrow and
