Maskell. — On Coccidae. 329 



Assuming a validity here for colour, M. fabricii may be 

 discarded as having the abdomen black. There remains the 

 question, for the others, of the tassels ; and here it must be 

 noted that these are exceedingly brittle, so that amongst 

 perhaps twenty specimens hardly five are found with the full 

 number, and the box in which I received mine was littered 

 with fragments of tassels. It is therefore quite possible that 

 the "three" of M. leachii and the "four" of M. saundersii 

 may really be five ; indeed, Signoret expresses the opinion 

 that saundersii and burmeisteri are identical. As for M. 

 atri'pennis, there is a doubt. West wood's words are not clear. 

 He says, " Abdomine . . . incisionibus profundis inter 

 segmenta, appendiculisque duobus carnosis hirtis apicalibus," 

 which may mean two or more tassels — Signoret takes him to 

 mean several. However, I will also discard this species for 

 the present. The three which are left are so similar in 

 colour, in size, and in the tassels that it seems immaterial 

 which we select ; but as M. hurmcisteri has alphabetical 

 precedence it may be well to adopt it, at all events until we 

 know more about them. 



The localities set down by Westwood for his species are all 

 in the oriental region, except for- M. illigeri, Tasmania, and 

 M. raddoni, Western Africa. I see no reason why M. hur- 

 meisteri should not, like so many other Coccids, range over a 

 wide extent, from India to Japan, or further. 



It is to be noted that Westwood, following Burmeister, 

 attributes twenty-two joints to the male antenna of Mono- 

 vhlebus. This error arose from a failure to observe the 

 compression of the joints, which those authors took for a real 

 division.

I received during the year, from Mr. Koebele, some speci- 

 mens of a species of Icerya, covered with cotton partly white 

 partly pale - yellow. At first this seemed to be new, and 

 perhaps allied to I. crocea, Green, a species from Ceylon with 

 yellow cotton ; but two of the specimens were so precisely 

 similar to a drawing of I. sacchari by M. Poujade, reproduced 

 by Signoret in his pi. xviii., fig. 2, that there was little room 

 for doubt that they belonged to that species. Further ex- 

 amination of the anatomical details, and comparison with 

 specimens of /. sacchari sent me in 1882 by Dr. Signoret, 

 satisfied me on the point. Only one character remained un- 

 certain : Signoret says that in the larva the tibia is excessively
