yellow) as well as in liabits from those in Myolin, the larva? of the 

 latter being parasitic upon Ilijmenoptera or Goleoptcra {CurculionuJce), 

 while those of the former are said to live in the bodies of the cater- 

 pillars of Lepidoptera {'^esiai). 



L. AUEEA, Fin. 



Jiavescens, Dsv. 

 Ochreous ; head and face golden-yellow, with silvery glitter ; frontal stripe 

 narrow, and reddish-brown ; antennae dark yellow ; palpi yellow, long and narrow 

 in the male, and slightly thickened at the end in the female ; thorax light brown, 

 with golden-yellow pubescence, and very faintly striped ; abdomen ochreous and 

 translucent, the sides and hinder edges of the segments having silvery-white 

 reflections ; calyptra and halteres yellow ; wings bi-ownish-yellow ; legs yellow, 

 with brown tarsi. Very rare. 



29.— R^SELIA, Dsv. 



Gen. cA.— Eyes nude, and distant in both sexes; fronto-orbital 

 bristles in a double row in both males and females, and descending to 

 the roots of the antennpe ; facial setae ascending half-way up the face ; 

 antennae with first and second joints short, and tbe third five or six 

 times as long as the second ; arista bare ; abdomen oblong and convex, 

 with the rings of nearly equal lengths, and with both discal and mar- 

 ginal setfe ; wings mostly without the apical cross vein, and having 

 the outer cross vein placed in the middle between the little (inner) 

 cross vein to the point of fiexure of the fourth longitudinal one. The 

 sexes are very difficult to discriminate. 



R. PALLIPES, Fin. 

 nntiqua, Mgn. 

 Cinereous ; forehead slightly prominent, frontalia wide, with a broad black or 

 piceous stripe ; antennse with the first and second joints rufous or testaceous, and 

 the third black, with the apex pointed in front ; palpi rufous ; thorax with four 

 narrow lines, the outer ones small and broken ; scutellum yellow at the apex ; 

 abdomen grey and immaculate, with the sides slightly rufous and diaphanous ; legs 

 yellow, with black tarsi, fore femora sometimes nigrescent at the base. There is no 

 doubt that Meigen's R. antiqua is only a variety of T. paUipes, Fin., in which the 

 apical cross veins are deficient ; therefore. Fallen's name, which has the priority, 

 must be adopted. Falle'n remarks at the end of his description of T. pallipes : 

 " Var. /8 9 Monstrosa, nervo alarum quarto abbreviate ;" this variety seems more 

 common than the other, and I cannot make out that it is a sexual peculiarity, as 

 Fallen's remark would lead one to suppose. This fly is not uncommon ; Mr. 

 Brunetti sent me two captured at the same time at Dulwich, in one of which the 

 apical cross veins are present, and in the other absent ; I have one or two specimens 

 captured by myself, in which a small portion of this vein remains, while the rest is 

 deficient.
