tures along the outer margin. This system of punctuation prevails 

 throughout the other British species, with the exception of inclinans 

 and formosus. The abdomen is sparingly, but strongly, punctured ; 

 the punctures being thickest at the base of the segments. The apex 

 is set with stiff and long hairs. 



A variety is mentioned by Erichson, in which the Ihorax also is 

 rufo-testaceous. It appears possibly to be the Tachinus merdarius of 

 Gryllenhal. 



I have a male of this species, in which (though otherwise typical) 

 the apical joint of the antennae is very flat, and the elytra are obsoletely 

 punctured all over, besides the usual striae ; the punctuations presenting 

 much the appearance of the depressions caused by rain falling gently 

 upon soft mud. 



Hammersmith Marshes, Stockwell, Preston, Paisley, Falkirk, 

 Glasgow, Hampstead, Crystal Palace, &c. ; not very uncommon.

3-3^ lin. Very like analis in build and colour, but differing in 

 being rather larger and broader, with a more depressed and ample 

 thorax ; also in having the two first joints of the antennae testaceous, 

 the third ferruginous, and the two apical joints testaceous ; the apical 

 joint is also rather more acuminate. The aaterior coxae are black, and 

 the apical joint of the abdomen pitchy. The punctuation of the striae 

 on the elytra is more remote, and not so distinct, and the basal joints 

 of the anterior tarsi in the male are more dilated. 



Erichson remarks that the penultimate joint of the antennae is 

 ferruginous in the female, instead of testaceous, but I find that some- 

 times the male exhibits this colouration, and sometimes the female has 

 both the apical joints decidedly testaceous. 



Varieties appear to occur, in which the two basal and the apical 

 joints only are testaceous ; also in which the three apical joints are 

 testaceous. 



Much rarer than the preceding. Eenfrewsh., Linlithgowsh., For- 

 farsh., and summit of Catlaw (Mr. Hislop,), Paisley, Weybridge. 



3. — INCLINANS, Grav. ; Erichson, loc. cit., 271, 3. 



3-3| lin. Eufo-testaceous ; head, except the mouth, pitchy-black ; 

 the four first segments of the abdomen pitchy, with the hinder margins 

 rufo-testaceous, the fifth segment almost entirely, and the two apical 

 entirely, nifo-testaceous. The apical joint of the antennae acuminate.
