THE CANADIAN ENTOMOLOGIST. 93 



the suture between 3 and 4 is not very distinct. Legs with femur + 

 trochanter 90 ; tibia 51 ; tarsus 50, or rather more. 



Hab. — Mendoza, Argentine Republic, Jan. 26, 1898, on pithy stems 

 of some herbaceous plant. This agrees with Hempel's C. novcesi in the 

 small legs, with the tibia and tarsus about equal ; it also agrees externally, 

 except that the wax of novcesi is paler and not so red. It seems best 

 to regard the two as geographical races of one species. 



(S.) Ceroplastes Bernardensis, n. sp. — Waxy scale about 63^ mm. 

 long, 6 broad, and 5^ high, cream)- white, not divided into plates nor 

 marked with white lines ; dorsal nucleus white, with no dark area 

 surrounding it. Denuded $ lively ferruginous, blackish dorsally ; length 

 47^, breadth 3, height 2^2 mm.; dorsum with a longitudinal crest ; caudal 

 horn short but large, directed backwards. 



Anal area with a ferruginous chitinous patch, the edges of which are 

 not well defined ; anal plates shaped as in C. scutigera ; skin with 

 scattered minute perforations ; mouth-parts small, about 130 // diameter. 



Femur + trochanter, 135 \>, ; tibia 100; tarsus 66. 



Antennae about 240 //, long, 8-jointed ; joints measuring : (1.) ?, 



(2.) 42, (3.) 33, (4-) 33, (5-) 39, (6-) 18, (7.) 18, (8.) 30. 



Hab. — San Bernardino, Paraguay, Sept. 23, 1897. On twigs of 

 undetermined plant. This agrees externally with the species which 

 Hempel regards as C. Janeirensis, but the structure appears to be 

 different. I cannot reconcile Hempel's Janeirensis with Signoret's account 

 of that species, and believe it is wrongly identified. The South American 

 species of Ceroplastes .are so numerous that it is next to impossible to 

 identify them by such descriptions as were given by the older authors ; 

 fortunately, these descriptions are few, and the great majority are well 

 described by Mr. Hempel. 



C. Amazonicus resembles Bernardensis, but on close inspection it is 

 seen that the wax is divided into plates, though the sutures are colourless. 



A CANADIAN ANOPLONYX. 



BY W. HAGUE HARRINGTON, F. R. S. C, OTTAWA. 



Among Hymenoptera which I sent to Provancher in 1885 was a 

 sawfly which he determined as Nematus malacus, Nort. As it did not 

 correspond to the description of that species, it was set aside with some 

 undetermined material. While rearranging my Nematidae, I recently 

 examined the insect to ascertain its generic position, and found that
