M. vuLPiNUs, Fin. 



Tliorax black, covered with white tomeiitum, and marked with four longitudinal 

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

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

 white tessellations, assuming the form of irregular broken transverse bands on the 

 sides ; cheeks bare ; chin with a few soft haii's, but no bristles ; legs testaceous, with 

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

 Sphecia bembeciformis. 



M. FULGENS, Mgn. 



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. 



Rare. 



M. HJEMORRKOIDALIS, Fin. 



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

 nished with both hairs and bristles ; by the antennae 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 tibiae 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 Mr. 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 ; 

 antemije 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 ; proboscis long, narrow, pointed, and projecting hori- 

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

 third longitudinal vein setigerous. 



A. LONGIROSTRIS, Mgn. 



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 froutalia and palpi are testaceous, the latter having 

 black tips in the male, according to Macquart. Tliis 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-frontai bristles in both sexes ;* facialia unarmed ; cheeks 

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



This only appUes to the fir.st and typical species.
