334 DIPTERA OF NORTH AMERICA. [PART IV. 



CTEDOIVIA' Philippi. 

 (Section LIMNOPHILINA.) 



The following has been translated from Dr. Philippi's article 

 in the Verh. Zool. Bot. Ges. in Wien, 1865, p.' 602 (Tab. XXIII, 

 fig. 2):- 



Head small, globose, attenuated behind, produced anteriorly in a stout, 

 horizontal rostrum. Eyes globose, rather remote. No ocelli. The an- 

 tenna in length are equal to about three-quarters of the head and the 

 thorax taken together ; from 15- to 24-joiuted ; first joint cylindrical, stout, 

 the second equal to one-third of the first, subglobular ; the following eight 

 (or twelve) cylindrical, subequal, emiting a filament and thus forming a 

 comb ; the projection of the third joint is on the external side, and short ; 

 the fourth joint has one on the inside and another on the outside; the 

 joints 5, 6, 7, 8, 9, 10 and beyond, have on the inside a long projection ; 

 joint 11 has a short one on the inside ; the nine following joints are cylin- 

 drical, and difficult to distinguish. Palpi four-jointed, joints cylindrical, 

 the fourth stout, rather short, although a little longer than the third. The 

 tibiae have two spurs at the tip. 



Four species from Chile are described. The wings, as I 

 judge by the plate, have two submarginal, five posterior, and a 

 discal cell ; the second submarginal and first posterior have their 

 inner ends almost in a line ; the second marginal is but little 

 shorter than the submarginal. The venation is altogether like 

 that of' an ordinary Limnophila. 



POLYM0RIA2 Philippi. 



(Section LIMNOPHILINA?) 



The following is translated from Dr. Philippi's article on the 

 Diptera of Chile in the Verh. Zool. Bot. Oes. in Wien, 1865, p. 

 608 (Tab. XXIII, fig. 3) :— 



" Head produced in a rostrum, as in Tipula ; third joint of the palpi 

 stout, the fourth slender. Antennae short, 16-jointed ; first joint elongated, 

 cylindrical, stout ; the second stout, subglobular ; the following gradually 

 decrease in size, short, with long hairs. Wings with six* posterior cells, 



' From xTuJwv, comb. 

 * From wsXu?, much, and /nooiov, part. 



^ Philippi says : six posterior cells ; but both figures given by him show 

 only five.
