M. TULPiNUS, Fin. 



Thorax black, covoivd witli white tomontiini, and marked witli four longitudinal 

 black stripes ; shoulders and sides yellow ; seutelUini yellow ; abdomen rufous, with 

 a wide longitudinal black dorsal stripe, which does not reach the apex, and with 

 white tessellations, assu)ning the form of irregular broken transverse bands on the 

 sides ; cheeks bare ; chin with a few soft hairs, but no bristles ; legs testaceous, with 

 the knees and tarsi nigrescent. Not rare ; has been bred by Mr. F. Norgate from 

 Sphecia bemheciformis. 



M. ruLUEiSs, ilgn. 

 This species differs from the former by having the chin quite bare ; the legs 

 nearly black ; and the abdomen with the dorsal black stripe rather indistinct ; so 

 that it appears to be tessellated or variegated all over with red and white patches.

M. IliEMORRIIOIDALIS, Fin. 



This may be distinguished finm both the other species by the chin being fur- 

 nished with both hairs and bristles ; by the antennse having the second joint only 

 half the length of the third ; by the abdomen being "black with red sides, and white 

 tessellation, as well as having the anal segments red in both sexes ; and by the legs 

 being black, with the tibiffi partly testaceous. This species has not yet been recorded 

 as British, but I possess one specimen which I obtained many years ago from the 

 late ilr. F. Walker, with other British flies, and it is so common in Germany and 

 Scandinavia that I think it may be safely recorded as indigenous. 



3.— APHRIA, Desv. 



Gen. ch. — Eyes bare; face rather oblique; facialia unarmed; 

 antennfe drooping, second joint rather long, only a little shorter than 

 the third joint in the male, and subequal with it in the female ; arista 

 with the second joint elongated, it being about one-fifth of the length 

 of the third ; pi'oboscis long, narrow, pointed, and projecting hori- 

 zontally forwards ; fourth longitudinal vein bent upwards in a curve; 

 third longitudinal vein setigerous. 



A. LONGIROSTRIS, MgU. 



This (the only British species) is whitish-grey ; the thorax is marked by four 

 fine longitudinal black lines ; the scutellum is grey ; the abdomen is also cinereous, 

 with the first segment black, and having a black band on the posterior edges of the 

 other segments ; the second and third and sometimes the base of the fourth rings 

 are rufous on the sides; the frontalia and palpi are testaceous, the latter having 

 black tips in the male, according to Macquart. This rare Tachinid is in Mr. C. W. 

 Dale's collection. 



4— DEMOTICUS, Mcq. 



Oen. ch. — Eyes bare ; frontalia wide, and armed with a double 

 row of orbito-frontal bristles in both sexes ;* facialia unarmed ; cheeks 

 and chin bare ; antennae reaching the epistome, which is somewhat 



* This only applies to the first and typical species.
