MOSQUITO NOTES — II. 75 



dark brown narrow scales ; ochreous narrow scales round the front margin, round the 

 ante-scutellar space, and in two lines extending from the scutellum for nearly half 

 the length of the mesonotum ; in other specimens the dark scales are lighter and the 

 pale scales are more numerous, forming an indistinct pale median transverse band. 

 Scutellum with narrow pale ochreous scales. Prothoracic lobes with broadish curved 

 scales; pleurae with broad flat white ones. Abdomen ochreous, with dark brown 

 scales dorsally ; tergites 2-4 with complete basal creamy bands, broadening some- 

 what lateral^, 5 and 6 with lateral basal creamy spots. Venter pale-scaled, sternites 

 4-6 with dark apical bands. In the female the seventh segment is remarkably 

 small, narrow, and partly retracted ; the cerci are long and narrow, nearly three times 

 as long as broad. Male hypopygium : Side-pieces nearly cylindrical, almost four 

 times as long as their width at the base, without lobes, but with an aggregation of 

 hairs into a small dense patch at the base of the lower flap. Cla.spettes entirely 

 unrepresented. Claspers long, the outer third rather suddenly narrowed and curved 

 inwards ; terminal spine long, slender, almost straight. Lobes of ninth tergite small., 

 with a few short bristles. Mesosome rather short and broad, simple. Anal segment 

 normal. Legs entirely dark-scaled, except for the undersides of the front and middle 

 femora, and the greater part of the hind femora, except the tip and a line along the 

 upper side of the outer half. Claw-formula :— cJ 2 : 1. 1 : 1. : ; $ i ; i. i ; i.o-O. 

 Wings entirely brown-scaled ; scales of the lateral series long, linear, those of the 

 median series also rather long. Cell Ro as long as its stem in the male, longer in the 

 female, its base slightly proximal to that of cell M^. HaUeres ochreous, knob 

 somewhat darker. Wing-length 3-5-4 mm. 



Queensland : Eidsvold {Dr. T. L. Bancroft). Type female, 12 other females,, 

 and 3 males presented to the British Museum by the Imperial Bureau of Entomology ; 

 received through Mr. G. F. Hill. 



The only near ally of this species is 0. multiplex, Theo., which differs in thoracic 

 ornamentation, in the larger seventh segment of the female abdomen, and in the 

 straighter and nearly C3dindrical male claspers. 



Aedes (Ochlerotatus) ashworthi, sp. nov. 



Head clothed at the sides with broad flat whitish scales ; in the middle of vertex 

 with loosely applied narrower flat straight scales ; on the nape with quite narrow 

 curved scales ; bristles black. Proboscis dark-scaled, slender, nearty one-half longer 

 than the front femora. Palpi dark-scaled ; in the female nearly one-fourth as long as 

 the proboscis, the second joint swollen and longer than the first ; in the male about 

 four-fifths as long as the proboscis, long joint almost divided in the middle, equal in 

 length to the last two joints together, tip of long joint and whole of penultimate joint 

 with long dark hair, terminal joint very broad, slightly shorter than penultimate, 

 nearly bare. Thorax : Integument of mesonotum dark brown, with large pale humeral 

 patches, and traces of three blackish longitudinal lines ; mesonotal scales all narrow, 

 mostly ochreous, with some black ones intermixed. Pleurae with some flat, dull 

 whitish scales. Abdomen brown, a broad band of dull grey scales at the base of each 

 segment. Seventh segment of female large ; eighth sternite also rather large and 

 prominent ; cerci very small, not longer than broad. Male hypopygium : Lobes of 

 ninth tergite clothed with short hairs. Side-pieces about 3-5 times as long as broad, 

 the lower flap without lobes, but bearing on its edge a row of pecuhar bristles which are 

 flattened towards the tips, almost club-shaped, these bristles extending for more than 

 two-thirds of the distance from the base of the side-piece. Claspette represented by 

 a small basal lobe of the upper flap of the side-piece, this lobe truncating apically and 

 bearing about a dozen rather long twisted scales or flattened bristles. Claspers long, 

 nearly cylindrical, gradually narrowed and somewhat curved on the apical half, with 

 a moderately long terminal spine. Mesosome rather short and broad, simple. Legs 

 dark, except for the whitish undersides of the femora and the narrowly ochreous tips
