2. SUBFAM. MEGARHININ/E, Theobald 



This subfamily can be told from the following in which the palpi are long in both sexes by the 

 very small first submarginal cell and curiously bent proboscis. They are all large insects with brilliant 

 coloration and caudal tufts. They are frequent^ spoken of as Elephant mosquitos. The scale structure 

 differs widely from that of the Anophelina, the head especially. In scale structure and general appearance 

 they resemble the next subfamiry T oxorhynchitince but the o*'s of the lattei have short palpi. 



Characters. — ■ Head densely clothed with flat scales and some upright forked scales; palpi in 

 the £? long, acuminate, in the 9 n °t so long as the g* . Proboscis much curved. Antennae of o* plumose, 

 of 9 verticillate, basal joints scaly. Thorax clothed with spindle shaped scales, broader flat ones at the 

 sides and over base of wings ; scutellum clothed with flat scales ; metanotum nude ; prothoracic lobes 

 with flat scales. Abdomen covered with fiat scales and with a caudal fan of fine hair like scales always 

 present in the cj . Wings with very small fork-cells, the first submarginal being very small, the stems of 

 the fork-cells very long; in the cf the wings are longer and narrower than in the 9 j supernumerary 

 cross-vein nearer the apex of the wing than the mid. Ungues of 9 equal and simple, of q* unequal on 

 fore and mid legs, the larger always toothed. 



This subfamily at present contains only one genus (Megarhinus). The species are only found 

 in tropical and warmer subtropical countries.

Megarhinus. Robineau-Devoidy, Essai sur les Culic. (Mem. Soc. Hist. Nat. Paris), Vol. 3, p. 412 (1827). 

 Characters. — Same as those of the subfamily. The members present most beautiful metallic 

 coloration. Some are said to bite severely. They are mostly confined to South America, West Indes 

 Malay States and East Indes. Most are purely sylvan in habits. Larvae with siphon. 



(1) The type is in the British Museum, but I cannot find any description.
