To begin with I must state that I wrongly placed the species in my Key 
of the Formosan Dorylas (Ann. Mus. Nat. Hung., X. 1912. pag. 288.), as 
the scut ellum is not bare, but bears some tiny hairs on its hind margin. 
Therefore it comes near to D. gigas from which it differs at first sight by 
its smaller size. 
Eyes touching for about half the space between the vertex and the 
antennae. Frons dull black but in the middle a very little raised, with a

a antenna, b hypopygium from above, c hypopygium from behind. 
shining black callus towards the upper part. Vertex black. Back of the 
head light greyish. 
Abdomen dull black, the only parts shining being the greyish pol- 
linose hindmargins and the greater part of the hardly pollinose fifth segment, 
which bears on the disc two circular depressions, and is 1% times as long 
as the fourth. Hypopygium very small, only a third as long as the fifth 
segment, brownish pollinose ; depression fairly large, oval, on right side. 
The hind femora are bare and shining behind, but not in front, which 
was a mistake in my description. 
All three males come from Formosa, Kankau (IV. V., 1912.). 
The name mutilatus Kert. had to be changed for this name had 
already been used by Loew for an African species.

Eyes touching for more than half the space between the vertex and 
the antennae. Vertex and frons black, but it is possible that the latter is 
also covered by greyish white tomentum like the face, as the head is a little 
greasy. Back of the head dull black and well puffed out, brownish grey on 
the upper half with many very tiny bristles. Antennae blackish brown on 
the basal joints, but yellowish brown on the third joint; the second joint 
bears some long bristles above and beneath, the longest of which extend 
beyond the end of the third joint ; the third joint is short, pointed but not 
rostrate; arista black, the thickened base yellowish. Proboscis orange.
