on windows in houses, in marshy places, and on putrid sub- 

 stances, as dungheaps, &c. Mr. F. Walker iniorms me that 

 he has 50 species, many of which he captured by sweeping 

 grass, and others were flying about cucumber-frames. I am 

 indebted to Mr. Haliday for the species figured, as well as for 

 two very distinct ones which I shall describe. The following I 

 am able to record as native species : 



A. Winged, a. Wings as in Meig. t. 62. f. 16. 



1. B. grossipes L. ? 



b. Wings as in Meig. t.62.f. 17. 



2. B. subsultans L. — curvipes Lat. Belfast Mr. Haliday, and South- 



gate Mr. Walker. 



3. B. denticulatus Meig. May, meadows, Southgate, Manchester, Scot- 



land and Belfast. 



c. Wings similar to the species figured. 



4. B. nitidus M. — 5. equinus Fall. — 6. niger M. Southgate, and 5th 



at Belfast. — 8. fimetarius M. 

 8^. B. hamatus Hal— Curt. B. E. pi. 469 S • 

 11. B. ater M. Southgate, and middle of October, Lowestoft Denes. 

 17- B. rufipes.? M. April, paling near a dunghill; middle of October, 

 Isle of Wight. 



e. Wings as in Meig. t. 62. f. 20. 



23. B. limosus Fall. Belfast and Southgate. 



24. B. silvaticus M. The male of this insect has very curious interme- 



diate legs ; there is a brush of hair on the thighs beneath, a pen- 

 cil of bristles inside the tibiae, and others at the apex ; the 2 first 

 joints of the tarsi are elongated, and the basal one is emarginate 

 beneath ; the penultimate joint of the abdomen is furnished with 

 a curved process at each angle. Beginning of May, Suffolk, Bel- 

 fast and Southgate. 



25. B. fenestralis Fall. Southgate.— 26. clunipes M. May, Suffolk, 



Dorset and Southgate. 

 27. B. pumilioM. Southgate. — 29. ochripes ikf. Southgate and Belfast. 



f. Wings shorter than the body ; 4th and 5th nervures not united. 

 29*. B. nivalis Hal. Scarcely 1 line long : rather dull piceous ; hypo- 

 stoma ochreous : wings brownish ; legs ochreous brown; inter- 

 mediate tibiae with 2 pairs of bristles on the outside. 

 Common about roots of trees in the winter, Belfast, 

 g. Wings with the 2nd longitudinal nervure not reaching the apex, and 

 forming a large oval cell, the transverse nervures close together at 

 the centre. 

 29''. B. nigerrimus Hal. Length one third of aline. Velvety black ; seta 

 of antennae pubescent ; wings transparent ; anterior tarsi a little 

 dilated. Taken near Belfast. 



B. Apterous. Meig. t.62.f.2\. 

 30. B. pedestrisM. Banks of theWandle above Wandsworth, Mr. Haliday; 

 and end of March, amongst moss, Glanville'sWootton, Mr. Dale. 



The Plant figured had a scent somewhat like violets at a 

 distance, when growing, but was very offensive when dried: it 

 seems to differ materially from the Phallus fcetidus Lam. 

 {P. impudicus Linn.); I found it in some abundance on the 

 sand-hills near Lowestoft, Suffolk, in the middle of October. 

 Flies of all descriptions were much attached to this Fungus, 

 and, as well as bees and beetles, seemed very fond of the shining 

 matter which dropped from the pileus.
