in the Muscites. Imago with the apical seta of the antenna 

 exarticulate ; ligula large, fleshy, bilobed 

 and pilose ; alula of the wings wanting ; 

 wings rather wider than in the preceding 

 order, beautifully variegated, striped and 

 spotted with different shades of black and 

 brown ; body glabrous, or with a slight 



Tephritis cornuta. ., ., , 



pilosity, of moderate length and stoutness, 

 and, in the females, furnished with a large, exserted and 

 conspicuous ovipositor. Tephritis. 



Phytomyzites. Larva inhabits the interior of plants and 

 fruits, and sometimes putrid substances. Pupa as in the 

 Muscites. Imago with the apical seta of the antennae ex- 

 articulate ; ligula large, fleshy, clavate ; alula of the wings 

 wanting ; wings as wide as in the preceding order ; the 

 body very delicate, often very slender, glabrous ; colour 

 black, or black variegated with yellow. Phytomyza, Chlo- 

 rops, Meromyza, Agromyza, Discomyza, Gymnopa, Asteia, 

 Drosephila, Ochthiphila, Opomyza. 



Phorites. Larva inhabits the flowers and seeds of vege- 

 tables, and the larva of other insects. Pupa as in the 

 Muscites. In the imago the apical seta of the antenna is 

 composed of four joints, the three basal ones being very 

 short, the apical one very long ; ligula very short ; alulae 

 of the wings wanting ; wings very wide, extending beyond 

 the body, which is very small, acute at the extremity, and 

 in colour inclining to black or yellow. Phora. 



Borborites. Larva inhabits putrid animal and vegetable 

 substances. Pupa as in the Muscites. Imago with the apical 

 portion of the antenna perfectly simple and exarticulate, 

 sometimes orbicular ; ligula large, membranous and bilobed ; 

 alula of the wings wanting ; wings very large and wide ;
