proved to be Carcelia rasa Macquart (=Sisyropa angusta Braner and 

 Bergenstamm). This species belongs to the bombylans group which is 

 distinguished by having only one median anterolateral bristle on the 

 midtibia. It differs from C. gnava as follows: Head with front of 

 male at narrowest 0.17 to 0.18 (in three specimens) and of female 0.20 

 (in three specimens) of head width; 13 to 15 frontal bristles in male 

 and 7 to 11 in female which descend to even with arista; genu one- 

 twentieth eye height ; arista thickened on basal two-fifths. 



Thorax more thinly pollinose, so that it is difficult to see the median 

 mesonotal vitta; yellow color of male and female scutellum extending 

 on to posterior portion of scutum. 



Abdominal hairs of male about as long as macrochaetae, which 

 causes marginals of second and third segments to appear more or 

 less indistinct; usually only one pair of marginals on first abdominal 

 segment. 



This species has not been liberated in North America.

Carcelia rcclinata is almost identical in appearance with the Pale- 

 arctic species Carcelia cheloniae Rondani. The adults and puparia 

 of both species can be separated. It is surprising that the name C. 

 cheloniae was used to cover the material represented by Carcelia mala- 

 cosomae, new species, and the introduced species Carcelia laxifrons, 

 which are as easily separated from C. cheloniae as from C. reclinata. 



Head with front of male at narrowest 0.20 to 0.24 (in five specimens) 

 and of female 0.26 to 0.30 (in five specimens) of head width; frontal 

 row of 11 or 12 bristles in male and 6 to 8 in female, extending from a 

 little below base of third antennal segment to 2 reclinate upper frontals 

 (preverticals) ; facial ridge bristly on about lowest one-fourth, some- 

 times ascending higher in males ; gena one-twelfth or less eye height ; 

 frontal orbits silvery gray pollinose, gradually becoming blacker 

 toward vertex, especially so in female ; face, gena, and posterior orbit 

 silver-gray pollinose; antenna black, third segment of male nearly 

 four times and in female about three times length of second; arista 

 thickened on basal one-third, penultimate segment usually a little 

 longer than broad ; palpus yellow, base inf uscated.
