10. Upright forked scales; 17. Heart shaped scales. 



1 1 . Twisted upright scales ; 



The head is ornamented in a variety of ways with the following scales — upright 

 forked, flat spatulate, narrow-curved and spindle shaped, according to the genus. The eyes are large 

 and reniform, the number of facets varying in the different species. (This is a useless character however 

 as the eyes shrink and become so distorted that the facets cannot be counted.) 



The palpi vary very much in form and also in the number of joints not only in different species, 

 but in the two sexes. They may be composed of one segment only (some Aedines) or of six segments 

 (some Culicines); there are basal constrictions which sometimes may become joints. All stages in length 

 occur from those as long or longer than the proboscis to those single jointed ones scarcely perceptable. 

 It is thus impossible to use them as generic characters particularly as they vary even in the same species 

 according to Xeveu-Lemaire. 



The antenna are pilose in the 9 m a U cases; in the male the}' are usually plumose, but in some 

 genera (Sabethes, Deinoceriies, Wyecmyia, etc.) they are verticillate; the hairs being rather longer than in 

 the 5 's. As a rule they are shorter than the proboscis but in one genus {Deinocerites) they are much longer. 

 The basal segments may or may not be scaled. In one genus (Lophocerataomyia) (1) the antenna? in the (f 

 have a curious sensory organ attached to them forming a distinct brush like process. The relative lengths 

 o the basal joints is also of specific importance in the Megarhinina. 



The proboscis in the 9 ' s composed of an upper and lower lip, the latter ending in the so called 

 lobelia, jointed processes of somewhat variable form, piobably the labial palps; these two parts form a 

 sheath in which lie in the 9 four stylets, two being the mandibles and two the maxillae, and in addition 

 a tubular organ the hypopharynx. In the 0* the mandibles and maxillae are much reduced but traces 

 may be found in certain species. The tf 's however do not bite. In form the proboscis is usually straight 

 and simple as long or longer than the body ; it may be curved (Megarhinina), straight (Culicinee) or elbowed 

 and jointed (Limatus). In Uranotania it is usually swollen apically and in the allied Mimomyias much 

 swollen along its apical half in the male sex. 



The thorax is divided into three well defined areas, the greater part being the mesonotum, in front 

 lie two more a less prominent lateral lobes — the prothoracic lobes — behind this the metanotum and 

 between it and the mesonotum is situated the scutellum. The scutellum is trilobed in most Culicidse 

 {Culicines and Aedines) but in the Anophtlinis and Corcthrines it is simple. All parts are scaly, except in 

 the A nopheles and Corethrina which may have hairs only on the thorax (Anopheles and Myzomyia). As a 

 rule the prothorax in Culex is bristly and not scaly, whilst in the Stegomyias,, etc. distinct scales occur. 

 In all Anophelina , Megarhinina and most Culicina the metanotum is nude, but in Joblotia it has scales 

 and chaetae, as it also has in many Aedines {Sabethes, Limaius, etc.) The scutellum has chaetae bordering 

 its edge (posterior border-bristles) these may vary in number in the same species (Culex faiigans) or 

 they may be constant (certain Aedines), they cannot however be relied upon as specific characters. 



The abdomen may be nude (Anopheles) or partly scaled (Cellia, Nyssorrhynchns) or completely scaled 

 (Aldrickia, Culex, etc.j, the scales may form a complete armour (Aldrichia, Culex, etc.) or may be loose 

 and ragged (Mucidus;, occassionally there are lateral tufts of scales (Cellia), ventral tufts (Myzorhynchus) 

 or caudal fans ( Megarhinus). The rj 1 abdomen is thinner than the 9 anQ ^ ' s usually (Culicines and
