Ceroplastes bergi, n. sp. 



AVaxy scale 9-11 rnm long, 8-9 broad, 4,5-6 liigli, irre- 

 gular, the insects usnally massed togetlier in great numbers ; 

 pía tes n ot distinguishable : wax bright pink throughout, tlie 

 pink coloring matter readily staining paper when the wax 

 is pressed upon it; conspicuous lines of white secretion, two 

 lateral and one terminal. 



Denuded of wax the 9 ^ s "^ mm l° n g» 3 broad, 1,5 high; 

 long oval, flattened, very dark red-brown, with a strcug 

 dorsal keel, in the middle of which is a prominent tubercle; 

 caudal horn rather large, but short and broad, mammiform, 

 broader than high; five marginal tubercles, two oneach side, 

 and one at the anterior end of the dorsal keel, all prominent. 



Antennae 9-jointed, formula 3 (29) (146) (578). The joints 

 measure approximately as follows in ¡j. : - (1.) 42- (2.) 48- (3.) 

 (30- (4.) 30-42- (5.) 30-32- (6.) 39-41- (7.) 30- (8.) 30- (9.) 48. 

 The suture between 5 and 6 is sometimes indistinct, but the 

 examination of several antennae shows that it is not a «false 

 joint». 



Háb. — Buenos Ayres, collected by Dr. Carlos Berg, who 

 reports that it is very common there on Schinas molle, Liga-

Ceroplastes bergi is a species of the gronp of C. ceriferus, 

 and is nearest allied to C. granáis Hempel, from which it is 

 easily distinguished by the antennae and the beautiful color 

 of the wax. 



The coloring matter of the species of Ceroplastes long ago
