96 [April. 



29.— K^SELIA, Dsv. 

 Gen. ch. — Eyes nude, and distant in bofb sexes ; fronto-orbital 

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

 the roots of the antennae ; facial setsD ascending half-way up the face ; 

 antennae with first and second joints short, and the 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 setsB ; 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 flexure of the fourth longitudinal one. The 

 sexes are very difficult to discriminate. 



E. PALLIPES, Fin. 



antiqua, Mgn. 

 Cinereous 5 forehead slightly prominent, frontalia wide, with a broad black or 

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

 the tliird 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 ancV immaculate, with the sides slightly rufous and diaphanous ; legs 

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

 doubt that 7' s R. antiqua is only a variety of T. paUipes, Fin., in which the 



apical cro/ -eins are deficient; therefore, Fallen's name, whi,ch has the priority, 

 must be adopted. Fallen remarks at the end of his description of T. pallipes : 

 ' Var. j8 9 Monstrosa, nervo alarum quarto abbi-eviato ;" 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. 



30.— MEiaENIA, Dsv. 



Tachina, p. Mgn. 



Masiceea, p. Mcq. 



Spilosia, End. 



Gen. ch. — Eyes bare or pubescent, approximated in the males, and 

 widely separated in the females ; fronto-orbital bristles extending to 

 about the apex of the second joint of the antennse ; facial setae few ; 

 anteunsD with the second joint somewhat elongated, and the third from 

 two to four times as long as the second ; arista bare, cheeks nude ; 

 vibrissae placed at some distance above the upper margin of the mouth 

 (epistome) ; abdomen conical, mostly spotted, and having both discal 

 and marginal setae ; wings with the fourth longitudinal vein bent at 

 an obtuse angle, and the outer cross vein placed rather nearer to the 

 angle than to the inner cross vein.
