A NKW WAXSCAI-E FROM THK ARGF.NTINK. 



BY T. 1). A. COCKKREI.L, IJNIVKRSHY OK COLORADO. 



The Coccidro of the Argentine Republic must be considerably more 

 numerous than the records show. A carefully prepared list, with full 

 bibliographical details, was i)ublished by Kugenio Auiran in 1907 (Hoi. 

 Minist. Agricultura, \'1I), but it shows only 32 species. One may now be 

 added ; I have had it in my possession for a number of years, but only 

 recently, with the assistance of Miss L. H. Falk, have I been able to 

 examine it in detail. 



Ceroplastes La/ii/lei, n. sp. 

 Waxy scale about 3 mm. long, 2^-2 broad and 1 ',■ high, solitary or 

 aggregated in masses more or less surrounding the branch, the wax of the 

 different individuals then completely confluent ; wax creamy-white, wholly 

 without red or brown ; dorsal patch oval, consisting of the elongate-oval 

 dorsal nucleus, and the six lateral and one anterior plates surrounding it, 

 having their several nuclei distinctly developed ; caudal |)atch with a large 

 dark spot, consisting of the caudal horn ; lateral wax abundant, convex m 

 section, more or less concentrically grooved, with the usual broad vertical 

 bands of chalky-while secretion. In lateral view the dorsal patch is hardly 

 or not visible.

 I 1/5 high ; pale ochreou*;, with the broad low shining mainmifi)rm caudal 

 horn deep chestnut-brown, in strong contrast ; dorsum obtusely keeled, 

 and sides with the usual tubercles. In lateral view there is a deep 

 impression between the dorsal hump and the caudal horn.
