Rhinophora. 249 



Female. Likewise quite similar to the female of chalyheata; the 

 bristles on second abdominal segment sometimes wanting. 



Length 4,5 to about 5 mm. 



M. nigrita is not rare in Denmark; Ordrup Mose, Lundtofte, 

 Hareskov, Ryget Skov, Nærum, Frerslev Hegn, Grib Skov, Humle- 

 bæk, Skelskør, Boserup, Svenstrup, at Sorø; on Lolland in Kæld- 

 skov; on Funen at Veflinge; in Jutland at Sønderborg, Augustenborg 

 and Skeide, and on Bornholm at Hasle; the dates are -^e irito August. 

 It is recorded to have been bred from a lepidopterous pupa. 



Geographical distribution: — Europe; towards the north to 

 middle Sweden. 



Remarks: Whether the above two species are really distinct 

 or only varieties of one, as Pandellé thinks, I dåre not decide. It is 

 well possible that chalybeata represents larger and stronger specimens 

 with the frons a little broader and cubital vein more bristly. On the 

 other hånd the difference regarding the eye-facets seems to speak for 

 their distinctness. — Dr. Bengtsson has communicated to me that 

 T. nitidiuscula Zett. is not present in Zetterstedt's collection, but 

 probably it is found in Boheman's collection. 



42. Rhinopliopa R. D. 



Small, shining, æneous black species with a little pruinosity on 

 abdomen. Head broader than thorax, slightly convex behind, especially 

 below, about as long as high. Frons somewhat narrow in male, broader 

 in female, very slightly protruding, and a little flattened or only 

 slightly arched from lunula to vertex. Jowls narrow. In both sexes 

 ocellar and inner and outer vertical bristles, and in female two orbitals. 

 Postocellar and occipital bristles distinct. Behind postocular bristles 

 black hairs. Frontal bristles reaching to lunula, about three upper 

 somewhat reclinate, and in female the uppermost directed outwards. 

 Cheeks with fme hairs. Vibrissæ not ascending. Eyes bare. Epistoma 

 not retreating, but reflected and rather protruding below. Oral cone 

 and proboscis of some length, slender; clypeus incised in apical half. 

 Palpi small, thread-like, slightly dilated apically. Antennæ inserted 

 below middle of the eye, third joint slightly longer than second; 

 arista pubescent. Thorax quadratic; three postsutural dorsocentrals 

 and an intermediate præsutural and a præscutellar pair of acrosti- 

 chals; two intraalar bristles. Scutellum with two marginal bristles
