CAMPYLOMYZA. 61 



Glossy black, nearly as large as Lestremia lemophcea, from which it 

 differs principally by the antennae ; the wings are alike in neuration. 

 Wings pure white ; veins colourless, except the two subcostal, which 

 are rosy in newly-disclosed specimens. Legs pale, much longer in the 

 male than in the female ; hind tibiae and tarsi white. 



Rare. (E. I.) 



Genus XIX. CAMPYLOMYZA. 



CAMPYLOMYZA, Wied.; Meig. Zw. i. 101 (1818); Mcq.; Westw. ; 

 Staeg. Cecidomyia p., Meig. Kl. Zw. Campylomyia, Zett. Porri- 

 condyla ? Rondani. 



Corpus oblongum, parvum aut minimum, plerumque nigrum. Caput 

 paryum. Oculi remoti. Ocelli tres. Proboscis brevis, arcuata. 

 Palpi parvi, porrecti, arcuati. Antennae 11-20-articulatae, monili- 

 formes, porrectae. Thorax ovatus. Alae mediocriter longae, sat 

 latae ; vena costalis cum cubitali ad alee apicem terminata ; medias- 

 tiualis obsoleta ; subcostalis alae dimidio paullo brevior ; venula ob- 

 liqua transversa subcostalem et cubitalem connectens ; vena subapi- 

 calis fere obsoleta ; subanalis distincta, analis angulata aut subobso- 

 lete furcata. Halteres parvi. Abdomen segmentis 8. Pedes sat 

 graciles, non elongati; metatarsus elongatus. Mas. Antennae mo- 

 niliformes, corporis longitudine ; articuli globosi, remoti, pilosi. 

 Abdomen lineare. Fcem. Antennae submonilifonnes, corpore multo 

 breviores; articuli approximati, pubescentes. Abdomen lanceola- 

 tum, valvulis duabus apicalibus. 



Body oblong, small, or very minute, generally black. Head small, 

 sessile. Eyes remote. Ocelli three. Proboscis curved. Palpi small, 

 porrect, curved. Antennae eleven- to twenty-jointed, moniliform, por- 

 rect. Thorace oval. Wings moderately long, rather broad; cubital 

 vein ending at the tip of the wing ; mediastinal obsolete ; subcostal less 

 than half the length of the wing, connected near its tip with the cubi- 

 tal by an oblique transverse veinlet ; cubital nearly straight, ending at 

 the tip of the costal ; subapical almost obsolete ; subanal distinct, 

 nearly straight ; anal forming with its second branch a slightly obtuse 

 angle, its first branch nearly obsolete, contiguous to the anal vein. 

 Halteres rather short. Abdomen with eight segments. Legs of mo- 

 derate length and thickness ; joints of the tarsi from the first to the 

 fourth successively decreasing in length. Male. Antennae moniliform, 

 as long as the body ; joints globose, remote, pilose. Abdomen linear. 

 Fetn. Antennae submoniliform, much shorter than the body ; joints ap- 

 proximate, pubescent. Abdomen lanceolate, with two apical valves. 



The Campylomyza abound in hedges and woods, and are not 

 uncommon on windows. In their habits they are allied to the 

 Sciartz, as well as to the Cecidomyia.
