SOME NEW MOSQUITOES FROM CEYLON. 239 



Observations. — Described from a single perfect £. Whether it will 

 oome in Megarhinus or Toxorhynchites it is not possible to say, but I 

 fancy it is a true Megarhinus. Its small size will at once separate it 

 from all known members of the two genera. It is also peculiar in 

 having spines or bristles in the place of a caudal fan and in the very 

 minute first fork-cell. The abdomen shows all manner of metallic and 

 color reflections.

 front ; pleurae brown with white puncta. Abdomen deep brown, the 

 third, fourth and fifth segments with basal median triangular white 

 spots, apical segments yellow-scaled, lateral white median spots to all 

 the segments. Legs with very narrow pale basal bands to some of the 

 tore and mid tarsi, broader ones on the hind pair ; knee spots snowy 

 white, also base of hind femora.

 apex apparently truncated. Antennae brown, basal segment testaceous. 



Thorax black clothed with rather long, thick silky white and creamy 

 narrow curved scales, most densely in front and rather broader scales 

 in front of the scutellum ; golden-brown bristles project over the

 and with golden-brown border bristles ; metanotum reddish-brown ; 

 pleurae brown with patches of white scales. Abdomen deep blackish- 

 brown, the third, fourth and fifth segments with a basal white median 

 spot, somewhat triangular on the fourth and fifth segments, the apical 

 segments with yellowish and creamy scales, except the extreme apex 

 which is black, no markings dorsally on the first and second segment, 

 each segment with lateral median white spots ; border-bristles small 

 pale golden. 



Legs brown with some basal white bands : on the fore legs there is a 

 narrow band at the base of the metatarsus and first two tarsi ; the base
