The following species also belong to the Subgen. AspJiondylia : 



C. Kibesii, Meig. On Rides rubrum ? 



C. Genistse, Loew. In green galls on Genista Germanica. 



C. Echii, Loew. In knobs on Echium vulgare. 



133. fasciata, Meig. Zw. i. 94. 2 (1818); Winn. Fcem. fusca, 

 antennis \^-articulatis, thorace fusco-flavo, vittis tribus nigro-fuscis, 

 pectore nigricante, alis pallide cinereis, halteribus abdomineque albidis, 

 hoc nigro-fasciato. Long. 3 lin. 



Fern. Brown. Antenna fourteen-jointed. Thorax brownish-yellow, 

 with three blackish-brown stripes, and with a black spot on each side 

 behind. Pectus blackish. Wings pale grey. Halteres yellowish-white. 

 Abdomen yellowish-white, with a black shining band on the hind bor- 

 der of each segment, from the first to the seventh. 



Meigen supposes that his C. grandis may be the male of C. 



fasciata, but does not mention whether the two are alike in the 

 structure of the thorax. Winnertz describes a male, and observes 

 that his, and the two following descriptions of males, Cecidomyia 



fasciata, Bremi, Neue Denkschr. Schw. Gesell. 60 (1847), and 

 Cecidomyia fasciata, Loew, Prog. Gymn. Pos. 31 (1850), com- 

 prise three distinct species. Rondani's genus Ozirhincus seems 

 to be nearly allied to this and to the following species. 



134. extrema, Walk. E. M. iii. 179 (1835) .cucullata, Meig., 

 var. ? Fcem. testacea, antennis nigricantibus %5-articulatis corporis 

 dimidio brevioribus, thorace vittis tribus fulvis, alis cinereis, pedibus 

 fuscis, pedibus robustis, tarsis incurvatis. Long. 2-2|; alar. 3^-4 lin.
