74 ENTOMOLOGY FOR MEDICAL OFFICERS 



slender. A small patch of flat scales between the eyes. 



Scutum with a conspicuous median white stripe. Rests like 



a Ctdex. 



6. Australian Species. 



Anopheles corethroides, Theobald. Wings not spotted. 

 Palpi and legs not banded. Three brown lines on the 

 scutum — one anterior and median, the others posterior and 

 lateral. South Queensland. 



Anopheles atratus, Skuse { = Pj/retophorus atratus, Theo- 

 bald). Wings with about six black spots formed by clumps 

 of scales ; the fringe at the tip of the wing is light grey, and 

 there are a few small grey spots in the wing-fringe proper. 

 Palpi and legs nearly black, the tip of the palpi pallid. 

 Scutum with some short, yellow, hair-like scales interspersed 

 among the sparse long hairs. 



Subgenus Myzorhynchus, Blanchard (Gr. fi.v^eiv = to moan, 



or to suck ; /5 Jyxo? = beak). 

 Including Myzorhynchus and Lophoscelomyia of Theobald's Monograph. 



There are no true scales in the field of the scutum, 

 though there may be some on its front edge and on the 

 pronotum. Abdominal scales are restricted to a single out- 

 standing tuft on the ventral surface of the penultimate 

 segment, except in one species { = Lophoscelomyia'} in which 

 the terminal segment is covered with narrow scales. Wings 

 very dark, though not without spots ; their front edge (costa) 

 never has more than two spots, exclusive of a spot which 

 may be present in the fringe at the tip of the wing ; these 

 two spots are usually small. The wing-scales are usually 

 spindle-shaped. The maxillary palps are always shaggy 

 with scales, though this character taken singly is by no 

 means diagnostic. 



One species is Palaearctic and one is Australian ; the 

 others are found only in the Oriental and Ethiopian regions. 

 As a rule they are rather large, black-looking, jungle 

 mosquitoes. 



I. European Species. 



Anopheles {Myzorhynchtis) pseiidopictus, . Grassi. Palpi 

 black, with three white bands. The first 4 tarsal seg-
