144 Knapiveed GaU-fly 



the description given by Schiner (1864) is more complete however, and 

 of this the following is a slightly abbreviated translation. 



" Wings yellowish- white, with brown bands, of these the first and 

 second are always widely separated at the anterior border. Body 

 glossy black ; thorax with a brownish-yellow dusted appearance, and 

 with the usual yellow side-stripes as in JJr. stigma ; scutellum yellow, 

 blackish at the sides. Ovipositor much longer than the abdomen, and 

 swollen from the base to the middle. Head yellow, posterior aspect 

 black or brown ; facial aspect paler, frons distinctly brighter in the 

 centre, sometimes rusty-yellow. Antennae, proboscis, and palps, 

 reddish-yellow ; proboscis lobes rather narrow, and much elbowed 

 backwards. Legs yellow, in most specimens the anterior femur with 

 a black stripe on the outer border, less frequently a similar stripe is 

 present on the mid and hind femora ; terminal tarsal joints brown. 

 Wings with a yellowish- white tinge ; at the base and towards the 

 anterior border as far as the stigma, a deeper yellow, with four lighter 

 or darker brown moderately straight cross bands. The first lies near 

 the wing base, is frequently indistinct, and reduced, but always present ; 

 it extends backwards at the most into the anal cell, and is always 

 widely separated from the second band. The second proceeds from 

 the point of the brownish-yellow stigma over the discal cross-vein, 

 almost completely straight to the posterior wing-border ; the third 

 arises at the anterior wing-border in front of the apex of the marginal 

 cell and proceeds moderately straight over the posterior cross-vein to 

 the posterior wing-border ; the fourth is usually narrowly continuous 

 with the third anteriorly, and borders the wing-tip just beyond the 

 fourth longitudinal vein. The clear area between the second and third 

 bands is at least double the width, or frequently only just wider than, 

 the bands themselves. Examples are found in which the bands are 

 very much faded, their position, however, is always distinctly recogni- 

 sable. Discal cross-vein a little beyond the middle of the discal-cell ; 

 3-1— 6-2 mm." 



Bezzi (1910, 1913) has recently proposed that the family name 

 should be Trypaneidae instead of Trypetidae, by which name this 

 family of acalypterate flies has been known so long. He divides the 

 family into two sub-families, the Dacinae and the Trypaneinae ; the 

 latter is divided into three tribes, Ceratitininae, Myiopitininae, Try- 

 paneininae. The second tribe contains only three genera : Mt/iopites 

 {Slylia), Asimonenra, and Urophora. 



Among other characteristics of the tribe Myiopitininae are the
