Scatopse Guorrr., Meic., Fase. Antenne undecimarticulate, 
perfoliate. Ocelli three. Palps very small, with a single joint. 
Sp. Scatopse notata, Tipula notata L., Metcen Europ. zweifl. Ins, 1. Tab. x. 
fig. 13; De Geer Ins, vi. Tab. 28, figs. 1—4, &c. 
Simulia Muta., Simulium Later. Antenne undecimarticulate, 
moniliform, cylindrical or fusiform. Ocelli none. Palps quadri- 
articulate. 
Small, but very troublesome species, with oral organs developed as in the 
genus Culex (according to the observations of CurTIS, cited by WESTWOOD, 
Introd. 1. p. 558), but shorter. With these they prick, which the Tipule, 
on the contrary, do not. In the south of Hungary, in the Banat, Simulia 
maculata, Musca columbaschensis GMEL., is sometimes, from the enormous 
numbers, very troublesome, and even dangerous. Here belongs also Simulia 
pertinax Kowiar, Brasiliens listige Insecten, fig. 14, which, under the 
collective name of Musquitos (Mosquitos, Moustigues), is joined to the 
gnats (Culices). According to HuMBOLDT, in all the Spanish colonies these 
last are not called Mosquitos, but Zancudos. In North America it seems 
to be the Culices which are named Mosquitos, whilst the Simulia are dis- 
tinguished from them as ‘black flies.’ 
tt Antennz longer than head, mostly of the length of head and 
thorax together. Joints of antenne various, mostly twelve or 
sixteen. 
Cecidomyia Meta. Antenne with 12 or more joints, filiform, 
porrect. Ocelli none. Wings incumbent. 
The larve of many species live in excrescences of plants, like the gall- 
wasps. Here belong Cecydomia destructor, the Hessian Fly of the North 
Americans, and Cecidomyia tritici Kirpy in Linn. Trans. Iv. p. 232, V- 
p- 96, Tab. 4, fig. 1. By such an insect, Cecidomyia salicina, those ex- 
crescences also are caused, which are sometimes seen in the form of double 
roses on the top of willow-branches. SwamMMERDAMM Bijbel der Natuur.
