CULICID^: THE ANOPHELES MOSQUITOES 69 



§ Nyssorhynchus Series. 



a. Abdominal scales present on some of the distal segments 



= Nyssorhynchus. 



b. Abdominal scales scattered over all the segments = '■'■ Neocellia." 



c. Abdominal scales fairly abundant on all the segments, and also form- 



ing regular outstanding tufts which may be either lateral or ventral 



= " Cellia." 



The following forms are not included in the above synopsis : — 



1. Aldrichia error, Theobald. One specimen from India, now in the 

 British Museum. As it stands it is a composite specimen, consisting of 

 the head, thorax, and wings of a Myzomyia rossii to which the dark scaly 

 abdomen of some other species of mosquito has been attached with gum. 



2. Bt'ronei/a £^racz'lzs, Theobald. Three males from New Guinea, now 

 in the Budapest Museum. According to Theobald the palpi are shorter 

 than the proboscis, the 2nd marginal cell of the wing is extremely small, 

 the wings are not spotted, and the covering of the thorax and abdomen 

 consists of hairs. 



3. Dactylomia, Newstead and Carter. One specimen from Ceylon. 

 Said to resemble a Myzomyia except for having a pair of projecting 

 finger-like thoracic lobes. 



Subgenus Anopheles {sensu restricto). 



Including Anopheles and Stethomyia and part of Cyclolepidopieron of 

 Theobald's Monograph ; and Neostethopheles and Patagiantyia, James. 



There may be some narrow scales on the pronotum and 

 front edge of the scutum, but the vestiture of the scutum 

 consists mainly of hairs, which are sparse. There may, very 

 rarely indeed, be a few inconspicuous narrow scales on the 

 genital lobes, but the vestiture of the abdomen also consists 

 of sparse hairs. The wings are either unspotted, or have a 

 few dark spots formed by clumps of scales ; or they may 

 have a few colour-spots, in which case not more than two of 

 these — distinctly formed— ^are present on the anterior (costal) 

 edge. The wing-scales are usually, but not always, long and 

 narrow. Palpi usually, but not always, slender. 



The subgenus is represented in all the great zoogeo- 

 graphical regions, but only just enters the Ethiopian region. 



I. European Species. 



Anopheles bifurcatus, L. A large species, in which there 

 are no spots on the wings, and no bands on the palps and legs.
