Confributions to the Study of thc Lipoueuridae Lw. 153 



Eyes hairy (a minute, short pubesccncc in all the specics; in 

 Bibioc. there is, besides, a secondary, longcr pubescoiicc on the 

 lower portion of the eyes; in Uapalothrix the eyes uro clothed 

 with long hairs). 

 Ocelli. Three, rather large. 



'SB, Dr. F. M. (p. 81, line 14 from bottom) observes tbat the ocelU arc 

 snialler in the $ [Snowia, f. 13), tbaii in the (f {Curujnra, f. 15); 

 in the latter they are placed on a protuberance on the Vertex A 

 sirailar protuberance in Hamm, (f (Loew, 1877, p. 75 at top), 

 Apist. Q.. Do such differences between (f and Q in the size of 

 the ocelli occur in other genera? 

 Antcnual flagellum with a microscopic pubescence, without verti- 

 cils (Loew, 1877, p. 64, Bleph. „Ohne alle längeren Haare"). 

 NB. In Lip. yos. I perceive some longer hairs on the proximal third of 

 the Segments. In Hapal. the antennal scapus is hairy, like the rest 

 of the body. 

 Palpi insertod at thc base of the proboscis, as far as observed, 

 four-jointed (Dr. Y. M. flg. 21 c/), sometimes apparently five- 

 jointed. 

 In Palt, Hamm., and Apist. the palpi are more or less abortive. In this 

 case these flies seem to foUow the law which prevails with many other 

 flies with a long proboscis, the palpi of which are stunted, like Ge- 

 ranomyia, Toxorrhina, Elephantomyia\ raost of the Cyrtidae etc. 

 NB. Bigot describes the palpi of Apist. as „triannulati, subcylindrici" 

 (Ann. 1862, p. 110). This description is just as exact as bis de- 

 scription of the palpi of the Midaidae „palpes etroits, non- 

 lamelleux" (Ann. 1857, p. 536). Mr. G. Tos writes me tbat he 

 could not distinguish any palpi in the specimen in the Turin Mus. 

 Thorax with a distinct transverse furrow, interrupted in the niiddle. 

 Body glabrous (hairy in Hapal.). 



Legs comparatively long; the bind pair longer than the others. 

 Spurs developed on the posterior tibiae only; on the two anterior 

 pairs they are wanting, or only rudinientary (no spurs in Hapal.). 

 Piilvilli none; empodia rudinientary. 



Ungues generally somewhat incrassate at the base; sometimes besct 

 with stiff, minute bristles on the under side. (Comp. Dr. F. M., 

 fig. lü, Curupira cf.) In Hapal. the ungues are abnormal, 

 pulvilliform. 

 Forceps of the male somewhat like those of the Limnohina, but 

 flatter, with many modifiications. (Comparison of the foi-ccps Bleph. 

 and Lipon, in Loew, 1877, p. 66.) Figures in Loew. 1877, f. 4, 

 Bleph. cap.\ in Dr. F. M., f. 24, Curupira, — In Bibioc. and 

 Agathon., the forceps is projecting, as in the Asilid Era^v.
