THE DIPTERA 



3. Thorax with hair-like, curved scales, and some narrow curved 



ones in front ; abdomen with apical lateral scale-tufts and scaly 

 venter; no ventral tuft. Wing scales lanceolate — Arribalzagia 

 Theobald. 



4. Thorax with hair-like, curved scales; no lateral abdominal tufts; 



distinct apical ventral tuft. Palpi densely scaly. Wing with 

 dense, large, lanceolate scales — Myzorhynchus Blanchard. 



5. Thorax with hair-like, curved scales, and some narrow, curved 



lateral ones ; abdomen hairy, with dense, long, hair-like, lateral, 

 apical, scaly tufts. Wing scales short, dense, lanceolate; fork 

 cells short — Christy a Theobald. 



6. Thorax with very long, hair-like, curved scales; abdomen with 



hairs, except last two segments, which are scaly. Dense 

 scale-tufts to hind femora. Wings with broadish, blunt, lanceo- 

 late scales — Lophoscelomyia Theobald. 



7. Thorax and abdomen with scales: — 



{a) Thoracic scales narrow-curved or spindle-shaped; abdo- 

 minal scales as lateral tufts and small dorsal patches of 

 flat scales — Nyssorhynchus Blanchard. 



(h) Abdomen nearly completely scaled, with long, irregular 



scales, and with lateral scale-tufts — Cellia Theobald. 



(c) Similar to above, but no lateral scale-tufts — Neocellia 



Theobald, 



[d) Abdomen completely scaled with large flat scales, as in 



Culex — A Idrichinella Theobald . 

 {e) Thoracic scales hair-like, except a few narrow-curved ones 



in front; abdominal scales long, broad, and irregular — 



KerUszia Theobald. 

 (/) Thorax with narrow, hair-like, curved scales, some broad 



straight scales, and some spatulate laterally. Abdomen 



with fine hairs except last three segments, which have 



scales. Tufts of scales on hind femora. Wing scales 



lanceolate — Manguinhosia Cruz. 

 Note. — The genus Ccelodiazesis Dyar and Knab is said by Theobald to be 

 invalid, being based on Anopheles, barberi, which is a true Anopheles. 



Anopheles Meigen, 1 81 8. 

 Essentially Anopheles are temperate zone or hill-station Anophelinge, of 

 which the type Anopheles maculipennis Meigen, 181 8, has been already 

 described. 



Eighteen species are definitely known, but in addition there are the uncertain 

 species of A . ferruginiensis Wiedemann; A. martini Laveran; A. pursati 

 Laveran; A. vincenti Laveran; A. vestitipennis Dyar and Knab, 1906; A. strigi- 

 macula Dyar and Knab, 1906; A. apicumacula Dyar and Knab, 1906; A. 

 punctimacula Dyar and Knab, 1906; etc. 



Theobald gives the following table by means of which the species may be 

 recognized: — 



Anopheles. 



A. Wings spotted: — 



I. Legs unhanded: — 



1. Wings with spots formed of collections of scales ©n the wing 



field; no costal spots — -maculipennis Meigen. 



2. Wings with light and dark costal markings. 



(i) Costa with two yellow spots: — • 



{a) Large species : — 



(a) No fringe-spots — punctipennis Say, 



(b) Fringe-spots present — pseudopunctipennis Theo- 



bald. 



[b) Small species. Wings much spotted — franciscanus 

 McCracken. 

 (2) Costa with one spot — perplexus Ludlow.
