140 C. STRICKLAND — THE MYZORHYNCHUS GROUP 



joins the latter, involving also the upper branch of the second long vein ; the 

 fringe with a small golden spot at the apex, at the junction of the third vein. 

 Legs very narrowly banded at the articulations ; fifth tarsal segments black. 

 Abdomen black, with dark hairs. 



Myzorhynchus umbrosus, Theo. 



Remarks. Dr. Watson, of Klang, has found a variety of this species charac- 

 terised by two costal spots, but the examination of a large number of specimens 

 of the typical form and of the variety has shewn that the two types are united 

 by annectant forms. The asserted absence of all scales on the abdomen is not a 

 specific character, for I have seen specimens with the last abdominal segment 

 covered with black scales on the dorsum. 



Definition. Mosquito with black palps less than half the width of the head 

 and with the last tarsal segment of the hind leg black. 



Naked-eye appearance. A blue-black mosquito without obviously banded legs, 

 and the mouth-parts not heavy in appearance. Wings not dappled. 



Description. Head: a tuft of long white scales projecting forward over the 

 clypeus from the vertex, behind this a triangular patch of bluish white scales, 

 and elsewhere clad with dark brown upright scales. Palpi and proboscis all 

 black. Thorax : prothoracic lobes with a large cockade of clavate scales ; 

 mesonotum clad with pale golden hairs, a tuft of fine white scales anteriorly, and 

 below each shoulder a tuft of dark brown curved scales. Wings with a spot on 

 the costa at the junction with the first long vein ; wing-fringe with a small yellow 

 spot at the apex, otherwise black. Legs minutely banded at the articulations. 

 Abdomen black, with pale hairs. 



Myzorhynchus albotaeniatus, Theo. 



Remarks. Leicester's specimens were described as having the fifth tarsal 

 segment of the hind leg black at the apex ; the specimens which I have seen 

 have been entirely white at that place. Another point is that the latter have all 

 had an apical wing-fringe spot, which appears to have been absent in Leicester's 

 examples. 



Definition. Mosquito with black palps, and the hind legs very broadly banded 

 with white. 



Naked-eye appearance. A bluish black mosquito, without dappled wings and 

 with the hind legs obviously banded with white. 



Description. Head with a tuft of golden hairs and hair-like scales projecting 

 forward from the vertex, on the occiput a few white upright scales, and on the 

 rest dark brownish black upright scales. Palps and proboscis black-scaled. 

 Thorax : patagia with a tuft of dark brown scales on their apices ; mesonotum 

 clad with golden hairs. Wings with two costal spots, one small one at the 

 junction of the subcostal vein with the costal, and one at the junction of the first 

 long vein at the apex, which also involves the upper branch of the second long 

 vein. Legs : fore and mid legs narrowly banded, hind legs broadly banded with 

 white, the remainder being black ; the banding is complete on the last tarsal 

 segment and extends on to the penultimate segment distally for a third of its 

 length, the next three joints being marked by a broad band which extends on to 

 the segments on each side of the joint. Abdomen black, clad with pale hairs.
