Fig. 2. Mesothoraeic appendages of Dinothrips monodon, male. 
This species is to be distinguished from sumatrensis by the 
form of mesothoraeic appendages and of the fore tarsal tooth 
in the male ; but I could not find any other differences, and I am 
therefore unable to distinguish the females. The description 
of affinis Bagnall from Sarawak I have not yet seen. 
Mindanao, Butuan (leg. Baker), 1 male. 
Dicaiothrips bakeri sp. nov. Figs. 3 and 4. 
Wholly brownish black, fore tibiae and tarsi paler, yellowish 
brown, darker, blackish brown along outer and inner margins. 
Antennae very dark, coal black, only the third joint paler, yellow- 
ish, with the apical third blackish.
