230 MR, walker's catalogue of dipterous insects 



femora with a black subapical band ; tibiae with blackish tips ; wings 

 whitish, long, narrow ; veins pale testaceous with numerous black 

 bands ; halteres whitish with blackish tips. Length of the body 5-7 

 lines ; of the wings 16-20 lines. 



The wing-veins of the following species are much like those of L. stri- 

 givena ; but the veinlet between the 2nd and 3rd externo-medial veins 

 is much nearer the base of the former. 



5. LiMNOBiA auADRiFURCA, n. s. FcETO. Ccrvina, vix gracihs, an- 

 tennis nigricantibus pallido cinctis, thorace vittis quatuor piceis antice 

 connexis, abdomine vitta dorsali nigra, pedibus nigricantibus, femo- 

 ribus pallidis apice nigricantibus fascia subapicah pallida, tibiis basi 

 pallido fasciatis, alis pallide cinereis, costa fulva, venis pallide testaceis 

 nigro conferte cinctis, linea subapicali obliqua nigricante. 



Female. Fawn-colour, hardly slender; antennae short, blackish, with 

 pale rings ; thorax with four piceous stripes, which are united and 

 form a piceous disk in front ; abdomen with a black dorsal stripe ; 

 legs blackish ; femora pale, blackish towards their tips, near which 

 there is a pale band ; tibiae with a pale band at the base ; wings pale 

 cinereous ; costa tawny ; veins pale testaceous, with very numerous 

 black rings ; an oblique blackish line at the base of the apical areolets. 

 Length of the body 7 lines; of the wings 16 lines. 



The wing-veins of the next species differ much from those of the two 

 preceding LimnobitB in structure, though the veins are slightly cui-ved 

 near the tip of the wing ; the veinlet which connects the cubital vein 

 with the 1st externo-medial vein is nearly opposite the veinlet which 

 connects the 1st and 3rd externo-medial veins and emits the 2nd. 



6. LiMNOBiA PERDECORA, n. s. Mtts. Picca, breviuscula, sat robusta, 

 thorace antico perangusto, abdomine pallide testaceo apicem versus 

 nigro, pedibus piceis longis, femoribus testaceis apice nigricantibus, 

 alis fcrrugineis, costa fasciisque duabus nigricantibus, macula costali 

 subapicali nivea. 



Male. Piceous, rather short and stout ; mouth prominent ; antennae 

 short, with the 1st joint long; thorax very narrow in front ; abdomen 

 pale testaceous, black towards the tip ; legs piceous, long, slender ; 

 femora testaceous, blackish at their tips ; wings ferruginous, irregularly 

 blackish along the costa, and with two irregular blackish bands which 

 converge hindward and enclose the transverse veinlets ; a snow-white 

 spot near the tip of the costa ; halteres pale testaceous. Length of 

 the body 7 lines ; of the wings 14 lines. 



7. LiMNOBiA TERMiNALis, u. s. Fosm. Ocliracea, capite iigro, ani- 

 tennis setaceis, thorace vitta lanceolata picea postice abbreviata guttis- 

 que duabus lateralibus nigris, abdomine fasciis duabus apiceque nigris, 

 pedibus nigris, femoribus basi ochraceis, alis fuscescenti-cinereis, 

 venis halteribusque nigris. 



Female. Ochraceous ; head black ; smtennae short, setaceous ; thorax
