This species is very closely allied to the preceding, but is at once distinguished by the colour of the palpi. 
The expansion of the fore wings varies from eight to ten lines. It is of a blue-black colour ; the head has a 
very slender white line before the eyes; the palpi are entirely black in the female, but in the males they are 
white on the underside ; the thorax is unspotted above ; the breast has a large fulvous patch on each side. The 
abdomen has the fourth segment fulvous red ; this segment on the underside in the female is black, with a white 
margin; but in the male it is entirely white, as well as the extremity of the abdomen, The fan-tail is 
unspotted, the markings on the wings are black ; the tibiee blue-black, and the tarsi paler. 
This species is the most abundant of the red-belted kinds in gardens round London in May and June. I 
believe it was this species which Mr. Vigors reared from the apple-trees in his garden, in Whitehead’s Grove, 
Chelsea. Mr. Newman thinks it probably feeds on the pith of the Rubus ideus. Near Hertford, Ripley, and 
Dublin, are mentioned as its localities by Mr. Stephens. I have taken it in a sand pit near Woolwich (at the 
beginning of June 1822), and in other places in the neighbourhood of London.

Conopia Myopeformis 2, teste Newman. 
Expansion of the wings 114 lines. ‘‘ Blue-black head, with a slender silvery line before the eyes; palpi 
totally black ; thorax glossy immaculate ; breast with a fulvous patch anteriorly ; abdomen shining, with the 
fourth segment above bright fulvous-orange, interrupted by a broad dusky black line beneath, caudal tuft 
immaculate ; femora blue-black, tibiz the same, the anterior yellowish within; the spines black ; tarsi blue- 
black above, yellowish beneath ; anterior wings above, with the base, costa, nervures, a broad transverse line, and 
the apex, deep bluish-black ; beneath with the costa at the base, the margins of the discoidal line, and the space 
between the nervures at the apex (which are very broad and dusky-blue), bright golden fulvous ; posterior with 
the nervures, margin, and anterior lunules, bluish-black ; beneath the same, with the costa slightly margined 
with fulvous.” This is Mr. Stephens’s description of “‘a single specimen in beautiful condition,’ which he con- 
jectures to have been taken at Darenth, having been informed that Mr. Chant possessed a pair captured 
there on the IOth July, 1825, and that Mr. Davis found a specimen at Gravesend. MHiibner figures hos 
Stomoxyformis with two red stripes on the thorax; and Mr. Stephens’s Latin character accords therewith, 
but not with the English character which he gives. Moreover, in the description of his plates, Mr. Stephens 
states the specimen figured by him to be a female. Mr. Newman, however, having “ carefully examined 
the specimen described and figured by Mr. Stephens, and also those in the cabinets of Mr. Davis and
