one tub seven larvae of Teromyia quasifevox were found. Two species of 
Lophoceratomyia, L. pallidus and Mammilifer and Taeniorhynchus domestica 
and conopas. 
Much of the ground round the houses and settlement is overgrown 
with long grass or low scrub. Into this thick growth innumerable tins, 
bottles and other artificial receptacles have been thrown and it is to this 
accumulation of rubbish which affords suitable breeding places for mosqui¬ 
toes that the prevalence near such land of mosquitoes is to be attributed. 
The presence of Stegomyia fasciata the carrier of yellow fever so far 
inland is exceptional in this country and is the more remarkable that no 
specimens of this mosquito were found on the coast. 
As compared with the West Coast of the Malay Peninsula there are 
certain points of resemblance. Verralina Butleri and Stegomyia fusca have 
been found only on the East and West Coast and the same may be said for 
Myzorhynchus umbrosus. 
Most of the other mosquitoes are found on the East Coast but are 
widely distributed and occur inland as well as on the coast. Of these 
Culex fatigans, Stegomyia scutellavis the three species of Mansonia , the three 
Desvoidea , the two Taeniovhynchi , the two Lophoceratomyiae, Teromyia quasifevox 
the two Uranotaeni are examples. Stegomyia fasciata occurs in Singapore 
but only in a few places on the Western coast as at Port Swettenham, 
Penang, etc. 
As regards the mosquitoes themselves some of the species represented 
have only been occasionally found elsewhere these include Mansonia annula- 
tus, Culex hivsutipalpis; Desvoidea aurolineata, Taeniorhynchus conopas , Lophocera¬ 
tomyia mammilifer. Uranotaenia fusca is a new species but closely allied to 
U. inornata. Certain mosquitoes showed some variation from the type parti¬ 
cularly Cellia Kochii (vide Dr. Leicester’s description). Of the pitcher plant 
mosquitoes the Teromyia appears to be a new species but the male 
resembles T. funessus. It is described below as Teromyia Ater nov. sp. 
The Colonomyia is only definitely separated on account of the marked 
difference in the larvae and pupa from C. Caerulocephala. There are three 
varieties but the differences, merely of colour, are so slight that it is doubt¬ 
ful if they are distinct species. It is described below as Colonomyia Mendacis. 
Teromyia Ater .—As seen by the naked eye appears to be almost black in ordinary 
light with black caudal tufts. When brightly illuminated is metallic colouring seen 
green on the thorax and purple on the appendages. 
Female Head .—Thickly clad with scales black but when brilliantly illuminated green 
and yellow. Eyes black. 
Antenna .—Basal joint black but covered with white scales. Clypeus black Proboscis 
and palpi black but when brilliantly illuminated showing brilliant purple reflections. 
Thorax .—Black covered with broad lanceolate scales showing yellow-green reflections. 
Pleura black with patches of silvery-white scales. Prothoracic lobes covered thickly with 
white scales. Legs purple-black Under surface of femora white. Lighter broad bands 
on tibia and metatarsus of middle legs. Scutellum covered with dark scales with greenish- 
yellow reflections. 
Abdomen .—Dorsal surface dark purple. Venter white scaled. Lateral hairs white. 
These are longer on the sixth segment and continuous with the caudal tufts of long dark 
brown hairs on the seventh and eighth segments
