Occurrence .— I am indebted to Dr. Finlayson of Singapore for the 
pecimens of this mosquito. They are all bred from larvae found in pitcher 
>lants in the neighbourhood of Singapore. 
Remarks .—It is a very distinct species and when fresh a very beautiful 
nosquito the purple of the abdomen being magnificent but the colours fade 
erribly when dry. In some respects it resembles M. ferox, but the 
.bsence of the caudal tuft the total difference of the cross veins of the wing 
.nd the bright purple abdomen distinguish it at once. Though there is no 
audal tuft the build of the insect and the five-jointed palpi prove it to belong 
. o this genus rather than Toxorhynchites. In some respects the mosquito 
esembles M. purpureas, but the female palpi have no resemblance to those 
igured by Theobald as those of M. purpureus. The cross veins also differ 
n M. purpureas from these specimens and the leg banding in the mid legs is 
>n the metatarsus and first tarsal joint in T. Acaudata whereas in 
1 1 . purpureus it is on the first two tarsal joints. 
Teromyia Ouasiferox. n. sp. 
m 
Thorax black with brilliant metallic bronze-green fusiform scales 
! >n the dorsum, on the margin a broad stripe of scales varying in colour 
Ivith the light, from azure-blue to apple-green and at times almost 
.ilvery-white and over the wing roots patches of bright peacock-blue spatu- 
ate scales with similar scales in front of the scutellum; some of the 
. pecimens shew an ill-defined bluish central stripe. Scutellar scales varying 
rom bright apple-green to peacock-blue. Head with bronze-green scales 
vith a margin of silvery scales along the eyes edged behind with peacock- 
due and laterally swelling into a small patch of silvery or pale green scales. 
3 alpi purple with violet and rose tints above at the apex, and at the apex 
>f the second joint. Legs much banded in the female. The whole tibia of 
nid leg except the extreme apex golden scaled. Metatarsus golden with a 
bale green apex ; tarsal joints white. Knee spots of all legs peacock-blue. 
jAbdomen with first segment apple-green, second segment bronze-green, 
remaining segments steel-blue; caudal tuft orange and black. 
Female Head. —Black, clad with large bronze-green spatulate scales; 
dong the eyes is a silvery margin edged behind with peacock-blue scales 
-pecially well seen on the vertex, so that passing backwards from the eyes 
*ou have first silvery scales then a margin of peacock-blue merging into the 
)ronze-green. In certain lights all the bronze-green look peacock-blue and the 
ilvery orbital margin takes on a beautiful rose-pink. Right back in front of the 
i nargin of the occipital foramen are three or four rows of dark brown upright 
orked scales difficult to see unless the head is flexed. Basal joint of antenna 
>lack, densely clad with small piriform silvery scales, second joint brown, with 
lark brown scales at its base, and some dark brown hairs; remaining joints 
orown, thickly covered with downy hairs and dark brown verticils. Palpi 
,.bout one-third the length of the proboscis, five-jointed; first joint small, 
(tbout as broad as long, second twice the length of the first, enlarged apically, 
hird as long as the two preceding, and the fourth and fifth of nearly equal size 
ind like two beads on the end of the third but quite distinct joints. Only the 
unction of second and third can be plainly seen when the scales are on.
