Collin — Notes on Specimens of Borboridce and some Ephydridce. 241 



4. Limosina arcuata Macq. — Three specimens, two labelled arcuata, are 

 curvinervis Stenh. {r oralis Rdi) ; five other specimeus are fontinalis Fin. 

 Haliday in his description said, " size of L. limosa ; sometimes but half the 

 size " : so he obviously included fontinalis, which are always larger than 

 curvinervis, and in addition have some acrostiehal bristles strongly developed. 

 In the errata at the end of vol. iii of Walker's Ins. Brit. Dipt., he placed the 

 name arcuata as a synonym oi fontinalis. 



5. Limosina geniculata Macq. — I found a pair of this species in the 

 Collection ; it belongs to the group with bristly base to costa, a strong bristle 

 on middle trochanters and incurved bristles on front of thorax. It is 

 exceedingly closely allied to breviceps Stenh., but appears to have a less 

 projecting keel between the antennae. 



6. Limosina crassimana Hal. — Originally described as follows : — 



" Sp. 6. L. crassimana. Nigra alis infumatis ; lialterihus fiiscis ; tarsis 

 crassis ; mas, tibiis anticis clavato-compressis. 



"Nerea stercoraria, Kob. D. 803. No. 2? 



" Black ; the front sometimes with a narrow reddish margin : arista 

 finely pubescent : scutel scarcely so long as the raetathorax (witli but 

 four bristles, as in all which follow to the end of this section) : legs 

 more pubescent than in any of the following ; spines or bristles of the 

 middle shanks scattered : feet thick ; fore pair evidently dilated in the 

 male, in which also the fore shanks are clavate and furrowed, and the 

 hind feet have two joints dilated : poisers brown or blackish : wings 

 rarely hyaline, generally dusky : nerves darker ; base of the costal ciliate 

 with short hairs ; the 2d ending nearer to the 3d than 1st : interval of 

 the cross-nerves generally one-half longer than the principal one. 

 (Length 1 ; wings 21 lines, sometimes less.) 



" In profusion everywhere on dunghills and hotbeds, more rarely 

 on fungi." 



A number of this very common species. 



7. Limosina ochripes Meig. — Eight specimens. Haliday described the 

 antennae as " black, or red at the base," and there is one specimen in the 

 collection which has the antennae distinctly yellowish on the first two joints; 

 tliis might pass iov fulviceps Rnd. were it not that it could hardly be called 

 much smaller than ochripes, and the last costal segment is not " manifeste 

 longlore, uon subsequale peuultimo."
