should be known as Mesohomotoma lutheri (Enderlein) ; T. sterculiae Froggatt 

 does not belong to the present genus but should be referred to another, perhaps 

 Neocarsidara. 



3. Mesohomotoma camphorae Kuwayama * 

 Several specimens from Samoa, and a large number in another collection 

 from Fiji, agree in every respect with Kuwayama's description of this Formosan 

 species. It would appear to be a widely distributed species in the South Pacific 

 Islands. This species in Formosa, however, was found on camphor trees while 

 the Fiji specimens before me were taken on foliage of the milo tree, which is 

 somewhat related to Hibiscus. A very closely similar species {Tyora hibisci 

 Froggatt) was described in 1901 as occurring on Hibiscus foliage in Australia. 

 While I have not had the opportunity of examining authentic specimens of 

 Froggatt's species, there is no doubt that the Formosan species is either identical 

 with it or dif?erentiated only by very minor characteristics. The fact that the 

 milo tree is rather closely related to Hibiscus is of special interest in this 

 connection.

There are a number of psyllid nymphs taken on Hibiscus foliage on Efate 

 Island, New Hebrides, by P. A. Buxton, 3.vii.l925. These may be nymphs 

 of Mesohomotoma hibisci (Froggatt), or perhaps of M. camphorae.
