The tprmin.il Scatomyzides have the seta simple; the antenna' a.wnys abort and .straight j they arc small and 

 glabrous Plies, black, and more or less varied with buff; the legs strong, and the eyes large. I be upper aide of 

 the bead is flat, with a brown, triangular mask, in which the ocelli are placed. They arc found in (lowers. Many 

 of their larva: mine the interior of vegetables, and some are very injurious to agriculturists, destroying vsrious 

 cereal plants previous to their fructification. The larva of Mitsca Frit semetunes destroy the barley cropa in 

 len, to the amount of 100,000 golden ducats in a year, being one-tenth of the produce. The larva- of Uscinii 

 pumilionii and Uncut a, Fab., are equally obnoxious. They constitute our genus 



Oacinis, Latr., to which we add the genus Ctiloropt, 

 Meig., and I'iophila, Fallen. 



The fifth division (Dolichocbra), which em- 

 braces the genus Te/anoccra, Dum., is closely allied 

 to the preceding, but the length of the second 

 joint of the antennae, which equals or surpasses 

 that of the third, at once distinguishes it. These 

 organs are porrected, as long as, or longer than, 

 the head, and pointed at the tip. The upper

surface of the head forms a triangle, obtuse at the tip. 

 Some have the antenna? shorter than the head. 



Otitet, has the seta simple, and tin- lower part of the face is not produced. 



Eut/u/cera, Latr., has the seta plumose, and the lower part of the face produced into a truncated muzzle. 

 The others have the antennae as long as, or longer than, the head. 

 Sepedon, Latr., has the antennae evidently longer than the head] and the seta simple. 

 Tctanocera, Dum., has the antenna as long as the head, and the seta sometimes plumose. 



The sixth division, Leptopodites, is remarkable for the length and slenderness of the feet, the 

 hind ones being at least as long again as the body, which is also slender and filiform ; all the tarsi are 

 short. The head is spherical or ellipsoid, and terminated in a point. The antenna; are very small. 

 They are found on plants, and many frequent aquatic places.

Valnliata, Fabr., has the head spheroidal, and the seta often plumose. 



X< iiiis, Fabr., has the habit of Micropeza, but differs in the antenna' being as long as the head. 



The seventh division, Carpomyzje, has the wings vibratile, spotted with black or yellow, an appear- 

 ance very like that of the Domestic Flies, but with the eyes apart, and the abdomen with four or five 

 external segments, mostly terminated in the females by a cylindric or conic ovipositor ; the antenna' 

 always short, with the seta rarely villose. The larva; of many species live in fruits or seeds, in the 

 germ of which the parent fly had deposited its eggs. 



Many species approach the preceding subgenera in the narrow and elongated form of the body, and long 

 as well as in the globular or more elongate I form of the head.

legs of I leinte length.
