In this paper, I am publishing a short notice of several Thy- 
sanoptera, which Prof. Charles Fuller Baker collected in the 
Philippine Islands and kindly sent to me for determination, 
several years ago. In this collection there are two very inter- 
esting specimens, each representing a new species; all the 
other specimens belong to Dinothrips sumatrensis Bagnall, a 
common and widely distributed bark-inhabiting species of the 
Indo-Malayan Archipelago. 
Dinothrips sumatrensis Bagnall. Fig. 1. 
This species is represented in the material before me by 
twenty-five females and seven males from Butuan, Mindanao 
(leg. Baker), one female from Los Banos, and one male from 
Mount Banahao, all Philippine localities. I have it in my col- 
lection also from the type locality, Nias Island, Sumatra, owing 
to the kindness of Mr. Bagnall; further from Java (leg. Docters 
van Leeuwen-Reijnvaan, under bark), from Perak (ex coll. 
Staudinger) and from Ceylon ( Horn 1899). From Ceylon this 
species was described by Schmutz (1913) as Dinothrips furci - 
fer; but in the original description of furcifer I could not find 
any distinction from the true sumatrensis, and an examination 
of the type specimen of Schmutz’s species in the Vienna Mu- 
seum — for which I am indebted to the kindnes of Mr. Hand- 
lirsch — has made it clear to me that furcifer is to be regarded 
as a synonym of sumatrensis. This species is further known 
from Bengal, Tonkin, and Burma, and through the whole Ma- 
layan Archipelago as far as New Guinea. 
The coloration of the antenna is very characteristic; it is 
wholly coal black, only the third joint paler, yellowish, at the 
end blackish. One of the females in the material before me 
has the left antenna anomalous. Not only the third joint, but 
also all following are pale yellowish brown. The antenna seems 
to be seven-jointed, but a closer examination shows that on
