OF BORNEO.—BY RICHARD S. BAGNALL.

I hope to make a closer study of this genus from other 
material in my possession which is not at the moment 
available, and from, I hope, the large amount of material 
recorded by Professor Buffa. 
W. Sarawak ; both species from dead bark and trees ; 
Mt. Matang, December, 1918 (G. E. Bryant). 
(b) Docessissophothrips group. 
Genus Docessissophothrips, Bagn. 
Docessissophothrips laticeps i Bagnall, 1915. 
Ann. & Mag. Nat. Hist. ser. 8, xv. p. 822. 
The species of this curious genus are apparently very 
rare; I have described five from remote parts of the world, 
and each is represented by but a single example. Mr. 
Bryant’s record suggests that the extreme rarity may be 
due to a specialized habitat. 
W. Sarawak, one male, Mt. Matang, January 28th, 
1914, under bark with termites (G. E. Bryant). 
(c) Trichothrips group. 
Genus Tetracanthothrips, Bagn. 
Tetracanthothrips horneensis, Bagnall, 1915. 
Tetracanthothrips borneen- 
sis, Bagn., head & prothorax. 
Ann. & Mag. Nat. Hist. ser. 8, xv. 
p. 595. 
A single male example discovered 
by Mr. Bryant is the type of this 
curious genus, chiefly characterized 
by the two pairs of finger-like meso- 
notal spines. It is quite a small 
insect, and apparently comes in the 
Trichothrips group. 
W. Sarawak, Mt. Matang, one brachypterous male, 
December, 1918 (G. E. Bryant). 
Genus Allothrips, Hood. 
Allothrips caudatus , Bagnall, 1915. 
Ann. & Mag. Nat. Hist. ser. 8, xv. p. 595. 
Described from a single specimen collected by Mr. 
Bryant. Hood erected the genus—separated from Tricho¬ 
thrips by the 7-jointed antennae, joints 7 and 8 being fused 
together—for a Nearctic species. 
W. Sarawak, Mt. Matang, one male, December 11th, 
1913 (G. E. Bryant).
