FAM. CULICID/E i3 



Geographical distribution of species. — It is extremely difficult to tell <j* specimens from tf's 

 of the next subfamily as the (f characters are practically the same both in regards to scale ornamentation, 

 venation and palpi.

3. SUBFAM. TOXORHYNOHITIN/E, NOV. subfam. 



This subfamily differs from the precceding in that the 9' s have the palpi short and rather thick; 

 differences as great as those between the Anophelina and Culicinte. Both species with caudal tufts and 

 species devoid of this form of ornamentation occur and it is probable that two genera founded on 

 this character should be formed. Several species previously supposed to belong to Megarhinus (the 

 species having been founded on the cf's only) are now included here. A single genus occurs. 



I. Genus TOXORHYNCHITES, Theobald 



Toxorhynchites. Theobald, Mon. Culic. Vol. i,p. 244 (1901). 



Characters. — Head clothed with flat scales and a few upright forked scales. Thorax with 

 small flat spindle shaped scales and long spatulate scales; scutellum clothed with long,flat scales. Meta- 

 notum nude. Abdomen clothed with flat scales, with or without a caudal tuft. Venation as in Megarhinus 

 Palpi of rf long; of 9 short and thick, composed of three segments. Proboscis curved as in Megarhinus. 



The genus occurs in Africa, Asia, East Indes and Australia. 



Geographical distribution of species. — The most widespread species is immisericors Walker 

 which is extremely variable, it occurs from Ceylon up India to the Malay States and East Indes and I am 

 inclined to think that the Australia Speciosa Skuse is only a variety of Walker's species. Africa also 

 seems the home of this genus. 



None have so far occured in South America where its place is taken by Megarhinus.
