Studies on Tipulidae IT. 203 
Walker, 1. c. and Verrall, Ent. M. Mag. Oct. 1886, p. 118). Usually 
an open discal cell, coalescent with the third posterior cell. The 
venation resembles Monogr. etc. IV, Tab. 2, f. 4 (Gonomyia sub- 
cinerea) but the praefurca is longer; the tip of the auxiliary vein 
reaches about the middle of the praefurca; its crossvein a short 
distance from the tip: the second‘ submarginal cell reaches a little 
more proximad; the great crossvein a little before the discal cell; 
the second section of the second vein is shorter, less curved; no 
marginal crossvein. Yellow stripe on pleurae, above the coxae; the 
membrans in front, between the collar and the mesonotum, yellowish; 
scutellum and praescutellar callosities yellowish; sides of the abdomen 
more or less distinetly yellowish. The scutellum seems to be variable 
. in its coloring, sometimes yellowish, and in other specimens with a 
more distinet yellow edge. Macquart (l. e.) notices this in his de- 
scription; he also had a specimen with a closed discal cell. — I have 
seen and determined this species in Prof. Bellardi’s collection. The 
forceps of @. lateralis is accurately described by Mr. Haliday (I. e.); 
it is very different from that of @. scutellata. 
G. cineta Egger seems to be closely allied to @. lateralis 
and to have a forceps of a similar structure; the scutellum is de- 
seribed as black or gray; the sides of the abdomen not yellow. 
Larva and pupa of @. schistacea are described by Mr. Beling 
in the Verh. Z. B. Ges. 1886, p. 195. The larva of @. tenella was 
found by the same in the sand of a half-dried brook (l. c. 1878, 
p. 56); no description given. 
Empeda. 
O. Sacken, Monographs etc. IV, p. 183, 1869; wings are repre- 
sented in Schummel, Beiträge, Tab. 2, f. 4 and 5. 
(?) Ilisophila Rondani, Prodr. Vol. I, 1856 (unrecognizable). 
Occurs in Europe (four species) and North America (one descri- 
bed and an undescribed species from California). 
Jlisophila Rondani of which I saw a specimen in Mr. Bigot’s 
collection, labelled by Rondani, is unrecognizable in his Prodrome, 
the more so as the typical species is called Erioptera lutea Meise. 
which is not an Eimpeda at all (compare the Note etc. below). 
Mongoma. 
Westwood, Trans. Ent. Soc. Lond. 1881, p. 364, Tab. 17, £. 1.

First submarginal cell short (as in Gonomyia) and the anterior 
branch of the second vein oblique; marginal crossvein anterior to
