56 THE CANADIAN ENTOMOLOGIST. 



mulberry leaves, is a curious species with a very short ovisac. 

 Lecanium kunoensis, Kiuv., is very much like L. cerasorum, Ckll., 

 and may possibly be the same. EuUcanium g/ajtdi (Lecanium 

 glandiy Kuw.) is an immense species, 15 mm. long, found on 

 apple, pear, etc. XylococcUi matsumimr is given as a new species, 

 but it was originally introduced to our notice in Insect World, March, 

 j 905. It is not a Xylococcus, but forms a remarkakle new genus. 

 The table of genera allied to Xylococcus, as given in Canad. Entom , Oct., 

 1899, p. 275. may be enlarged as follows : 



Antennae of adult female 8-jointed ; firsl joint extremely large; second 

 short, very much broadei than long; joints broader apicalty than basally; 

 last joint oblong, longer '.'nan any except the first; body elongated, 

 times as long as broad, blunt posteriorly; legs well developed, the 

 anterior femora noticeably stout; tibia' much longer than tarsi; no mouth. 



(Russia) Steinge/ia, X issonow (type .V. gorodetskia, Nassonow).* 



Antenna? of adult female 9 jointed. 



With an anal tube producing a long rod or thread of wax ; last 

 joint of antenna of larva moderate, with long bristles 



< Europe, U S.) Xylococcus, Loewr. 



With no anal tube ; last joint of antenna of larva exceedingly large, 



with short bristles (Japan, Ceylon) Kuwania, Ckll. 



Antenna? of adult female with 10 or 1 1 joints. 



female with a marsupium, in which the eggs are laid 



I Australia) Callipap/>us, Gtierin. 



Female without a marsupium ; broad posteriorly, not elongated, 

 antenna; 10-jointed. close together ; larva with antennas 7-jointed, 

 and very peculiar crab-like legs, the femur large ; male without 

 whorls of long hairs on the antennal joints: caudal brush long, 

 arising from the apical segment ; rudimentary hind wing with very 



large hooks (Japan) 



MatsucoccHs, Ckll. (type Matsucoccus matsumura, Kuwana). 

 Matsu is the pine-tree, on which the new genus was found. It is 

 evidently related to Callipappus, but much less specialized, probably 

 representing; the genera! stock from which Ca/li/>apfius arose. 



In his list, Mr. Kuwana enumerates only two species of Astero- 

 lecanium; but he himself has sent me two others; one new, the other (col- 

 lected by Mr. Kuroyuwa in the Lu Chu Islands) is A. bamhusce, Boisd. 



*I received this insect some years ago from Professor Nassonow, and 

 understood that he was about to publish it, which lie has done in Ann. Mus. Zool. 

 Acad. Imp. Sci., Si. Petersburg, xiii, p. 345. The specimen is now at the Bureau 

 oi' Entomology, U. S. Dept. of Agriculture,
