2 pis. 

 Date? Tipulidae, Limoniinae. Alexander, Ihid. (in preparation). 



Antennae with from 5 to 39 segments, in local species with not 

 more than 19, commonly 13 (Tipulinae, most Pediciini) ; 14 (most 

 Limoniini) ; 16 (most Hexatomini and Eriopterini) ; form of anten- 

 nae various, from moniliform and setaceous to serrate and pectinate 

 (males of Livionia, subgenus Rhipidia', Cfenophora; Tanyptera: Figs. 

 25, A, B; 34, F, G). Maxillary palpi with from one to four segments, 

 commonly the latter. Labial palpi reduced, at most 2-seginented. 

 Frontal prolongation of head in most Tipulinae bearing a small 

 ^'■nasus'^ or nose at apex of dorsal surface; in cases, the mouth parts 

 are produced into a slender rostrum that exceeds in length one-half 

 the entire body, this either comprised of a long, slender prolongation 

 of the front, with the reduced mouth parts at extreme tip {Elephan- 

 tomyia^ Fig. 46, L; Toxorhina) or else made up chiefly of greatly 

 elongated labial palpi {Limonia, subgenus Geranomyia, Fig. 34, C). 

 Eyes glabrous, rarely (Pediciini) short-hairy; eyes usually of moder- 

 ate size, separated above by the wide anterior vertex, the latter some- 

 times reduced or lacking, producing a holoptic condition (males of 

 Lhnonia species). No ocelli. Posterior sclerites of head sometimes 

 produced and narrowed behind. 



Pronotum usually well developed. Thoracic dorsum comprised 

 chiefly of the mesonotum, with well-developed praescutum (lying be- 

 fore the so-called V-shaped or transverse suture. Fig. 22, D), scutum, 

 scutellum, and postnotum, the latter with a median (mediotergite) 

 and lateral (pleurotergites) subdivisions. Praescutum often with 

 paired double dots {tuherculate pits) near cephalic end, or with a 

 polished impressed humeral area {jjseiidosutural foveae) on either
