of the femora and tibiae. Claw formula : (^2:1.2:1.1:1; $1:1.1:1.1:1. 

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

 median series also rather long. Cell Rg over twice as long as its stem in the female, 

 its base slightly proximal to that of cell Mj. Wing-length 4-4 -vS mm. 



Larva : Head rather broad for this group ; clypeal hairs all simple. Antennae 

 moderately long, slightly curved, almost cylindrical and nearly bare ; a single hair 

 just beyond the middle. Comb of eighth abdominal segment consisting of a triangular 

 patch of 50 or more pointed scales. Siphon about three times as long as its greatest 

 breadth, slightly contracted at base and tip, not very strongly chitinised. Pecten 

 short, consisting of about 12 (fewer in the younger larvae) sharp-pointed, simple 

 teeth, placed so close together that their bases touch ; the first of these teeth is situated 

 at about one-lifth of the length of the siphon, but in some specimens the actual pecten 

 is preceded by one or two small, widely-spaced, simple bristles. Hair-tuft of about 

 eight hairs, situated a little beyond middle of siphon. Tracheal tubes very large, 

 strongly chitinised, occupying almost the whole of the middle part of the siphon, but 

 strongly and abruptly contracted before the base of the latter. Anal segment with 

 a lightly chitinised saddle ; gills very small and globular. Brush well-developed, 

 with 10-12 elements. 



West Australia: Yallingup, ix.l914 {Dr. J. H. Ashworth). Type and one 

 other male, one female, and a dozen larvae presented to the British Museum by the 

 Imperial Bureau of Entomology in 1915. 



This species is nearly allied to 0. crucians, Walker {tasmaniensis, Strickland), and 

 0. (Caenocephalus) concolor, Taylor, differing from both chiefly in the details of the 

 hypopygium. 0. crucians has the clasper very much swollen in the middle, its 

 terminal spine shorter and stouter, and the flattened bristles on the margin of the side- 

 pieces much less numerous ; the terminal joint of the male palpi is much more slender. 

 Probably the specimens of 0. concolor from Tasmania recorded by Taylor are really 

 0. crucians ; the true 0. concolor from New South Wales (which was wrongly described 

 as having simple female claws) resembles 0. crucians in its hypopygium, but the 

 claspers are less swollen, the scales on the claspette lobes are less numerous, and the 

 last joint of the male palpi is swollen, as in 0. aslmorthi. Doubtless the three forms 

 are geographical representatives of the same type. 



Aedes (?Skusea) funerea, Theobald. 



A male and female, apparently of this species, have been received from Dr. Swellen- 

 grebel, from Amboina. No Australian male is available for comparison, and the 

 identification is therefore not absolutely certain, though probably correct. The male 

 hypopygium of the Amboina specimen does not show the least resemblance to 

 5. pembaensis, but, on the other hand, resembles that of Aedes panayensis, Ludlow ; 

 from this it differs in the absence of a long process at the base of the side-piece, and 

 in the presence of a short spine instead of a thick projection at the tip of the side- 

 piece. Probably the species would be better placed in the subgenus Aedes than in 

 Skusea, but much more knowledge of the biology of these forms is necessary before 

 their classification can be regarded as satisfactory. 



Aedes (? Skusea) funerea var. ornata, Theobald. 



Lepidotomyia lineata, Taylor, Trans. Ent. Soc, 1914, p. 191 (1914). 



A male and female have been received from Dr. Swellengrebel from Ceram. The 

 male hypopygium is identical with that of 5. funerea from Amboina, and the form is 

 therefore probably correctly regarded as merely a variety of S. funerea, in spite of the 

 striking difference in thoracic ornamentation. Two female paratypes of L. lineata, 

 sent by Mr. G. F. Hill, agree with the female from Ceram,
